Objective: The purpose of this study is to investigate the effect of low-dose atropine and dual-focus MiSight contact lenses on myopia control. Methods: This study included a retrospective review of patients (5–13 years old) started on MiSight contacts or 0.05% atropine with a ≥1-year follow-up. Outcomes included cycloplegic refraction, axial length measurement, and side effects. The right eyes were included in analyses. Results: One hundred children were treated with MiSight lenses (n = 55) or 0.05% atropine (n = 45) at an average age of 10.4 ± 2.1 years and 8.4 ± 2.5 years, respectively. At the 1-year follow-up, there was no difference from baseline in spherical equivalent or axial length in the MiSight group (p = 0.61, p = 0.98) or in the atropine group (p = 0.78, p = 0.97). Further, subgroup analysis based on age at treatment initiation (<9.5 years vs. ≥9.5 years) showed no age difference in baseline or final spherical equivalent and axial length in either the MiSight group or the atropine group. Linear regression analysis demonstrated no association between initial age and baseline spherical equivalent, baseline axial length, or the change in spherical equivalent in either the MiSight or atropine group. Conclusions: There was no significant difference in spherical equivalent or axial length after 1 year of treatment with either the MiSight contact lenses or 0.05% atropine eye drops. However, the limited sample size, the difference in age and ethnicity, and baseline refraction prevent a direct comparison between the two treatment groups. Full article

Background: Trabeculectomy and minimally invasive glaucoma surgery (MIGS) such as goniotomy aim to reduce intraocular pressure (IOP) and medication burden but are often performed in patients with differing disease severity. Methods: We retrospectively reviewed 100 eyes from 76 adults with glaucoma that underwent either goniotomy (n = 50; Kahook Dual Blade = 42, OMNI = 8) or trabeculectomy ab externo (n = 50) at a tertiary center between May 2022 and June 2023, with at least six months of follow-up. Baseline and six-month IOP, number of medications, and postoperative complications were recorded. Eyes undergoing trabeculectomy had higher preoperative IOP than those undergoing goniotomy (22.6 ± 7.7 vs. 19.1 ± 5.9 mmHg). Results: At six months, trabeculectomy achieved a greater absolute IOP reduction (8.8 ± 0.8 vs. 5.4 ± 0.8 mmHg; p = 0.004), likely reflecting higher baseline IOP, while goniotomy yielded a larger medication reduction (1.47 ± 0.30 vs. 0.72 ± 0.20; p = 0.041). Hyphema occurred more often after trabeculectomy, and the small number of OMNI cases precluded device comparison. Conclusions: In this short-term retrospective series, trabeculectomy achieved larger absolute IOP reduction whereas goniotomy offered greater medication reduction, highlighting the need to individualize surgical choice and confirm these findings in larger prospective studies.

Background: This study evaluates the incidence and outcomes of patients with dropped nucleus/nuclear fragment during phacoemulsification surgery; Methods: Retrospective review of continuous cases with dropped nucleus/nuclear fragment during phacoemulsification cataract surgery from January 2020 to December 2024. Demographic and perioperative data were collected and analysed. A good visual outcome was defined as a postoperative best-distance visual acuity of ≥6/12; Results: A total of 91,883 cases of planned phacoemulsification cataract surgery were identified, of which 175 (0.19%) were complicated by a dropped nucleus/lens fragment. Mean age was 71 years and median number of days from primary procedure to secondary fragmatome was 5 days. Good visual outcomes were achieved in 127 cases (73%). Median final intraocular pressure was 13 mmHg. Most patients required two (63%) or three (29%) operations in total and none developed endophthalmitis. Hypermature cataracts were present in 70 cases (40%) and were significantly associated with poor visual outcomes (p = 0.003). Surgeon grade and other pre-existing ocular co-pathologies known to increase posterior capsular rupture risk were not significantly associated with poor visual outcomes; Conclusions: Overall incidence and outcomes of cases complicated with dropped nucleus/fragment were favourable despite the presence of pre-existing risk factors. Emergent management is paramount to ensure good outcomes in patients. Full article

Background/Purpose: Ophthalmic triage is challenging for non-specialists due to limited training and rising global eye disease burden. This study evaluates a multimodal framework integrating clinical text and ophthalmic imaging with large language models (LLMs). Textual consistency filtering and chain-of-thought (CoT) reasoning were incorporated to improve diagnostic accuracy. Methods: A dataset of 56 ophthalmology cases from a Singapore restructured hospital was pre-processed with acronym expansion, sentence reconstruction, and textual consistency filtering. To address dataset size limitations, 100 synthetic cases were generated via one-shot GPT-4 prompting, validated by semantic checks and ophthalmologist review. Three diagnostic approaches were tested: Text-Only, Image-Assisted, and Image with CoT. Diagnostic performance was quantified using a novel SNOMED-CT-based dissimilarity score, defined as the shortest path distance between predicted and reference diagnoses in the ontology, which was used to quantify semantic alignment. Results: The synthetic dataset included anterior segment (n = 40), posterior segment (n = 35), and extraocular (n = 25) cases. The text-only approach yielded a mean dissimilarity of 6.353 (95% CI: 4.668, 8.038). Incorporation of image assistance reduced this to 5.234 (95% CI: 3.930, 6.540), while CoT prompting provided further gains when imaging cues were ambiguous. Conclusions: The multimodal pipeline showed potential in improving diagnostic alignment in ophthalmology triage. Image inputs enhanced accuracy, and CoT reasoning reduced errors from ambiguous features, supporting its feasibility as a pilot framework for ophthalmology triage. Full article

Diabetes mellitus (DM) is a debilitating chronic disorder that results in ocular microvascular complications, including diabetic retinopathy (DR) and diabetic macular edema (DME). Early detection and timely intervention for DR and DME are crucial for improving visual outcomes in affected patients. Ophthalmic imaging plays a vital role in the screening, diagnosis, and management of DR and DME. In this review, a comprehensive overview of the imaging modalities frequently utilized in the assessment of DR and DME, encompassing both structural and functional imaging techniques are presented. The key imaging findings that are associated with the various stages of DR and DME are underscored and their diagnostic utility in assessing disease progression and visual function are evaluated. Additionally, we discuss emerging imaging biomarkers that are currently under investigation, which hold significant potential for improving the diagnostic and prognostic capabilities of imaging for DR and DME patients. Finally, the advent of new imaging methods, such as ultrawide-field imaging (UWFI) and deep learning models, which have markedly improved the detection of retinal pathologies are considered.

Smartphone-based fundus cameras and telemedicine are an opportunity for accessing ocular health inequalities in under-resourced areas. The objective of this study is to evaluate the prevalence of retinal findings in a community in the Amazon and propose strategies to enhance ocular health. A retrospective study was conducted in a riverside community. Retinal photos from the posterior pole and optic disc were captured using a portable fundus camera. All photos and data were analyzed remotely by a retina specialist. The final sample was 107 participants, aged 52 ± 17. Retinal findings were detected in 37.4% (95%CI 28.7–46.8) of the sample; the three main retinal findings were epithelial changes (10.3%, 95%CI 5.6–17.1), chorioretinal scars (8.4%, 95%CI 4.2–14.8), and dry age-related macular degeneration (7.5%, 95%CI 3.6–13.6). This study detected retinal alterations in a similar prevalence to that of other under-resourced areas. Telemedicine is an opportunity to address health inequities, especially in ophthalmology, through relatively low-cost portable devices, supporting clinical decisions in areas with low health access; however, maintaining assistance after implementation is a challenge. Enhancing medical education and training local non-specialized health professionals in risk assessment, device handling, and data base use is reasonable to ensure follow-up. Full article

Background: Uveitis, although a rare complication of multiple sclerosis (MS), poses a significant challenge in clinical management. Traditional treatments like corticosteroids, immunosuppressants, and surgical interventions often provide limited efficacy. Treatment for MS-associated uveitis involves a combination of traditional and emerging therapies, with a growing emphasis on monoclonal antibodies (mAbs). While there is an increasing use of disease-modifying therapies for MS such as interferon-beta (IFN-β), mAbs are gaining attention for their potential to address both neurological and ophthalmological symptoms. Methods: We conducted a systematic review of the existing literature and analyzed the clinical effect of IFN-β and mAb therapies in the context of MS-associated uveitis, assessing their efficacy in reducing inflammation, maintaining visual acuity (VA), and minimizing steroid dependency. Results: MS-associated uveitis had improved or maintained VA in 95% (35/37) of eyes (21 patients) after an average of 34.7 months (range of 7.9 to 78.7 months) of IFN-β treatment. One hundred percent (10/10) of patients (19/19 eyes) had improved or maintained VA after a mean of 25 months (range 8 to 43 months) of mAb treatment. We also found that IFN-β effect on MS-associated uveitis is comparable to mAbs. Conclusions: We outline the need for further research through human data to strengthen current findings and guide evidence-based clinical practice. Full article

Optogenetics is a field that emerged with the goal of studying the physiology of nerve cells by selectively expressing opsins—channel proteins that can be activated by light exposure. Once the methodology was established, several research groups sought to express these proteins in damaged nerve tissue to restore proper signal transmission. Over the years, numerous efforts have been made to restore vision in patients with chronic degenerative diseases, particularly retinitis pigmentosa, with clinical trials yielding encouraging results. However, significant challenges remain, such as the difficulty of delivering the signal to specific retinal cells and the complexity of replicating the physiological activation of the target cells. As research continues, optogenetics remains a promising yet evolving field. This review aims to highlight the therapeutic advantages of optogenetics over currently available strategies and to promote further scientific exploration of this emerging discipline. Full article

Background: Glaucoma is the leading cause of irreversible blindness around the world and is characterized as a group of irreversible optic neuropathies with multiple risk factors such as age, race/ethnicity, sex, and intraocular pressure (IOP), amongst many others that play a role in disease etiology. However, IOP is the only modifiable risk factor, with higher IOP often causing increased damage to the optic nerve, resulting in the vast majority of medical and surgical treatments aiming to reduce IOP. There are a number of interventions available to treat glaucoma including micro-invasive glaucoma surgery (MIGS), whose usage has drastically increased due to its safety and efficacy. Studies also highlight the IOP-reducing effect of cataract surgery, which is the most common procedure performed globally. However, other, more targeted therapies and surgeries have been shown to have a more significant effect on IOP reduction. The objective of this study is to compare the IOP and medication reduction between cataract surgery (CS), MIGS, and MIGS and cataract surgery (MACS) clinical trials. Methods: This analysis consisted of publicly available data on CS, MIGS, and MACS clinical trials from 2005 to 2017 using ClinicalTrials.gov. Data reporting and synthesis adhered to PRISMA guidelines. MIGS interventions studied in this analysis include iStent^®, CyPass^® Micro-Stent, Ex-PRESS^®, Hydrus^®, PRESERFLO^™ MicroShunt, and XEN^® Gel Stent. The main variables of interest are the mean IOP and mean number of glaucoma medications used. The primary outcomes were the baseline, post-procedure, and reduction in IOP and glaucoma medication use. Cohorts were further subdivided by the follow-up period (6, 12, and 24 months), as well as their medicated or unmedicated status for pre-op IOP measurement. PROSPERO CRD42025102892. Results: A total of 21 trials were included in this review, comprising 3330 clinical trial participants: 7 CS trials (N = 570), 13 MIGS trials (N = 1577), and 9 MACS trials (N = 1183). All interventions studied resulted in a decrease in both the IOP and medication usage with varying degrees. At 12 months, the wash-out baseline IOP reduction (mmHg) was 6.9 (27.5%) for CS, 8.8 (34.0%) for MIGS, and 8.2 (32.6%) for MACS. The medication reduction was 0.8 (56.1%) following CS, 1.0 (39.5%) for MIGS, and 1.3 (86.4%) for MACS. At 24 months, the wash-out baseline IOP reduction was 6.3 (25.1%) for CS, 8.4 (33.1%) for MIGS, and 7.6 (30.1%) for MACS. At 24 months, the medication reduction was 0.9 (58.3%) for CS, 1.5 (79.8%) for MIGS, and 1.3 (86.1%) for MACS. Conclusions: The results indicate that CS, MIGS, and MACS all result in a decrease in the IOP and glaucoma medications; however, MIGS and MACS outperform CS in IOP and medication reduction. Adopting MIGS and MACS for patients with ocular hypertension or mild-to-moderate glaucoma will help improve patient outcomes through reducing the IOP and medication burden. Given that glaucoma affects certain populations to a greater degree, future research analyzing racial representation is critical in ensuring the appropriate applicability of clinical trial results toward diverse populations.

The prevalence of vision impairment and eye disease is higher among patients with chronic kidney disease (CKD), yet there are no standardized guidelines for this vulnerable population. We hypothesized that there are self-reported unmet ophthalmic care needs among patients receiving hemodialysis. We also hypothesized that limited awareness of the connection between eye health and CKD is a significant barrier to receiving eye care. Methods: From June 2022 to July 2022, patients on dialysis were recruited in-person at two Independent Dialysis Foundation sites in Baltimore, Maryland. Participants completed a survey assessing recent eye exam history, barriers to care, and health literacy. Results: Of 82 participants, 43 (52%) had not received a complete eye exam within the past year. The most common reasons were scheduling conflicts (15 [35%]), not wanting an eye exam (12 [28%]), and costs (6 [14%]). Less than half of respondents (40, 41%) were unaware of a relationship between kidney disease and eye health. Conclusions: Results suggest potential unmet eye care needs and low awareness of CKD-related ocular risks among dialysis patients. Interventions to enhance provider recommendations, improve health literacy, and reduce logistical barriers may help prevent avoidable vision loss in this high-risk population. Full article

Background: Intraocular lens (IOL) alignment is crucial for optimal performance in presbyopia-correcting designs. The aim was to report a case of a patient with a high angle kappa implanted with the continuous transitional focus (CTF) Precizon Prebyopic NVA IOL. Case presentation: A 51-year-old patient presenting large angle kappa values (0.6/0.8 mm) was implanted with the Precizon Prebyopic NVA IOL and followed-up 1 and 10 months post-surgery. This IOL is designed with a butterfly-shaped central area that allows the orientation of the lens so that the visual axis passes through the wider diameter of the optic zone. Postoperative refraction was −0.25D of cyl at 80° for the right eye and +0.25D −0.50D cyl at 170°. Corrected distance visual acuity (CDVA) at the last visit was −0.1 logMAR monocularly and −0.2 logMAR binocularly. Binocular uncorrected distance (UDVA), intermediate (UIVA) and near visual acuities (UNVA) were −0.1, 0.1 and 0.1 logMAR, respectively. The corrected binocular defocus curve exhibited outstanding vision at the 0.00D defocus level and showed a continuous range of functional vision from distance to near. Overall excellent satisfaction was reported, along with low levels of photopic phenomena. Conclusions: Precizon Presbyopic NVA IOL provided satisfactory vision and low levels of photic phenomena in a high angle kappa patient who would potentially be excluded from presbyopia-correcting IOL implantation.

This study reports an unusual case of dramatic change in visual acuity, pachymetry, and corneal topography in a patient with a history of Fuchs dystrophy and radial keratotomy following the use of Rho-kinase (ROCK) inhibitor. A patient with a history of 8-cut radial keratotomy (RK), astigmatic keratotomy (AK), and Fuchs dystrophy showed dramatic changes in visual acuity, pachymetry, and corneal topography after using one drop of netarsudil 0.02%. The dramatic effect of netarsudil in our patient may be due to increased penetration of a rho-kinase inhibitor from the corneal incisions, facilitating the effect on corneal endothelium, resulting in a dramatic improvement in corneal pachymetry. This suggests a potential role for corneal incisions to improve the effectiveness of rho-kinase inhibitors in patients with Fuchs dystrophy. Full article

Background/Objective: Age-related macular degeneration (AMD) is a leading cause of irreversible vision loss. Intravitreal anti-vascular endothelial growth factor (VEGF) therapy is the primary treatment for neovascular AMD. This study aimed to assess racial, ethnic, and gender representation in U.S.-based randomized controlled trials (RCTs) of anti-VEGF therapies. Methods: A systematic PubMed search identified 19 eligible RCTs. Titles and abstracts were screened, and demographic data were independently extracted and cross-verified. Chi-squared analysis was used to evaluate disparities in participant representation. Risk of bias was assessed using the ROBIS checklist. Results: Among 8003 participants across 19 trials, 92.3% were Caucasian. Asian, African American, Hispanic/Latino, and American Indian participants collectively comprised just over 5%. This underrepresentation of non-Caucasian groups was statistically significant (p < 0.01, df = 4) and not associated with study sponsorship. Gender analysis showed 59% female and 41% male participation, which was not statistically significant (p = 0.83, df = 1). Conclusions: Non-Caucasian populations remain significantly underrepresented in anti-VEGF RCTs for AMD. This raises concerns about the generalizability of trial findings to diverse populations. Future clinical trials must prioritize inclusive recruitment to ensure equitable, evidence-based care for all patients. Full article

Refractory full-thickness macular holes (rFTMHs) present a significant challenge in vitreoretinal surgery, with reported incidence rates of 4.2–11.2% following standard vitrectomy with internal limiting membrane (ILM) peeling and gas tamponade. Risk factors include large hole size (>400 µm), chronicity (>6 months), high myopia, incomplete ILM peeling, and post-operative noncompliance. Multiple surgical techniques exist, though comparative evidence remains limited. Current options include the inverted ILM flap technique, autologous ILM transplantation (free flap or plug), lens capsular flap transplantation (autologous or allogenic), preserved human amniotic membrane transplantation, macular subretinal fluid injection, macular fibrin plug with autologous platelet concentrates, and autologous retinal transplantation. Closure rates range from 57.1% to 100%, with selection depending on hole size, residual ILM, patient posturing ability, etc. For non-posturing patients, fibrin plugs are preferred. Residual ILM cases may benefit from extended peeling or flap techniques, while large holes often require scaffold-based (lens capsule, amniotic membrane) or fibrin plug approaches. Pseudophakic patients should avoid posterior capsular flaps due to lower success rates. Despite promising outcomes, the lack of randomized trials necessitates further research to establish evidence-based guidelines. Personalized surgical planning, considering anatomical and functional goals, remains crucial in optimizing visual recovery in rFTMHs. Full article

Background: In clinical practice, visual outcomes with anti-VEGF therapy may be worse than those observed in clinical trials. In this study, we aim to investigate the long-term outcomes of neovascularization treated with intravitreal aflibercept injections (IAI) in a teaching hospital setting. Methods: This is a retrospective, single-center study including 81 nAMD patients (116 eyes), those both newly diagnosed and switched from ranibizumab. All patients had a follow-up duration of at least seven years. Treatment involved three monthly injections followed by either a pro re nata (PRN) or treat and extend regimen. Follow-up care was primarily conducted by training physicians. The primary endpoint was the change in best-corrected visual acuity (BCVA) over seven years. Secondary endpoints included central retinal thickness changes, qualitative OCT parameters, macular atrophy progression, injection frequency, and treatment adherence. Results: Among the 116 eyes, 52 (44.8%) completed the seven-year follow-up. Visual acuity improved by +2.1 letters in the overall population (+6.3 letters in treatment-naive eyes) after the loading phase but gradually declined, resulting in a loss of −12.3 letters at seven years. BCVA remained stable (a loss of fewer than 15 letters) in 57.7% of eyes. Central retinal thickness (CRT) decreased significantly during follow-up in both naive and switcher eyes. Macular atrophy occurred in 94.2% of eyes, progressing from 1.42 mm² to 8.55 mm² over seven years (p < 0.001). The mean number of injections was 4.1 ± 1.8 during the first year and 3.7 per year thereafter. Advanced age at diagnosis was a risk factor for loss to follow-up, with bilaterality being a protective factor against loss to follow-up (p < 0.05). Conclusions: This study highlights the challenges faced by a retina clinic in a teaching hospital. Suboptimal functional and anatomical outcomes in real life may derive from insufficient patient information and inconsistent monitoring, which contributes to undertreatment and affects long-term visual outcomes. It also raises concerns about supervision in a teaching hospital which needs to be improved. Full article

Purpose: This retrospective study aimed to compare the efficacy of cycloplegic (CR) versus non-cycloplegic refraction (NCR) methods in detecting refractive errors among children and adolescents. Methods: Electronic data from pediatric ophthalmology clinics at the University Hospital “Sveti Duh”; Zagreb, Croatia, from January 2008 to July 2023, were analyzed. Comprehensive eye examinations, including Logarithmic Visual Acuity tests, subjective refraction, cycloplegic retinoscopy, slit lamp, and fundus examinations, were conducted. Results: The dataset included 1075 individuals, with 180 undergoing NCR and 895 undergoing CR. In premyopes, the NCR group had a longer follow-up (5.04 vs. 3.45 years; p < 0.001) with similar SE progression. In low myopia, NCR showed more negative first visit SE (−1.86 D vs. −1.35 D; p < 0.001) and faster progression (p = 0.01). In high myopia, follow-up was longer in NCR (5.08 vs. 2.08 years; p = 0.03) with no other significant differences. SE progression was highest in 4–6-year-olds and significantly faster in NCR (−0.61 vs. −0.40 D/year; p = 0.05). Conclusions: Cycloplegic refraction is essential for accurately assessing refractive status, especially in cases of low myopia, as it prevents misclassification and ensures precise evaluation in children and adolescents, thereby facilitating the appropriate diagnosis and treatment of refractive errors.

Background: Rundle’s curve describes the natural progression of disease as gradually worsening before reaching a peak and stabilizing. This study aimed to investigate whether Rundle’s curve could be applied to keratoconus over a five-year follow-up period. Methods: Longitudinal study. Patients with keratoconus who underwent Pentacam tomography imaging from the Australian Study of Keratoconus were included in this study. Patients who received surgical treatment for keratoconus were excluded. Latent class analysis was performed for five parameters: Kmean front, Kmean back, pachymetry pupil, pachymetry minimum and pachymetry apex. A total of 522 patients and 1041 eyes were included for analysis. Most parameters were stable. However, worsening keratoconus in a minority of patients (less than 5% of the population) was observed across the last year of follow-up. The patients that showed progression in the final year were younger in age and had higher baseline parameters. Results: This study suggests keratoconus does not conform to the classic Rundle’s curve of disease progression. Instead, keratoconus exhibits a distinct course characterized by an increased risk of progression among younger individuals and eyes with higher baseline parameter values. Conclusions: These findings underscore the importance of considering treatments that halt disease progression, such as corneal collagen crosslinking, particularly in this specific subgroup of patients.

Background: The prevalence of foveal hypoplasia in different inherited retinal diseases (IRDs) has not been compared in a large patient cohort. We aimed to investigate the prevalence and visual significance of foveal hypoplasia in IRDs. Methods: Participants included patients with IRDs and control subjects. All patients had macular optical coherence tomography (OCT). Results: Among our 357 patients, 123 had rod-cone dystrophy (34.5%), 22 had cone/cone-rod dystrophy (6.2%), 30 had macular dystrophy (8.4%), and 182 (51%) were controls. Having a phenotype of rod-cone (OR = 12.9, p < 0.001) or cone/cone-rod dystrophy (OR = 10.2, p < 0.001) was associated with higher odds of having foveal hypoplasia. Males had higher odds of having foveal hypoplasia (OR = 2.4, p = 0.006). The prevalence of foveal hypoplasia in the retinitis pigmentosa GTPase regulator (RPGR) group (8/15 (53.3%)) was significantly higher than in matched controls (0/15, 0.0%) (p = 0.002). Atypical foveal hypoplasia had the highest LogMAR of 0.50 (±0.37), which was higher than grade one 0.16 (±0.17) (p = 0.038). Grade one LogMAR was not different from normal fovea 0.20 (±0.28) (p = 0.572). Conclusions: We report that rod-cone and cone/cone-rod IRDs are associated with foveal hypoplasia. Based on our findings, detection of foveal hypoplasia in a patient with reduced vision should prompt consideration of an IRD. Full article

This case report describes a unique ocular finding in a 64-year-old male with a history of central serous chorioretinopathy with choroidal neovascular membrane, treated with intravitreal injections of Aflibercept. The patient was found to have an iatrogenic retro-lenticular non-pigmented cystic formation in the left eye, an anomaly not previously documented in the literature. Comprehensive imaging included ultrasound biomicroscopy and anterior segment optical coherence tomography. This report emphasises a rare ocular finding and the significance of recognising iatrogenic cataracts following intravitreal injections. It also highlights the necessity of individualised patient management and preoperative evaluations to prevent surgical complications. Full article
