Background/Objectives: Dry eye disease (DED) is a common condition that can significantly impact cataract surgery outcomes. Preoperative management strategies, including the use of moisturizing eye drops, may improve ocular surface health and postoperative recovery. This study aimed to compare postoperative outcomes in 71 patients undergoing cataract surgery between June 2022 and May 2023 at a single center with and without preoperative keratostill moisturizing eye drops (sterile aqueous 0.3% hydroxypropyl methylcellulose solution) determined using the ocular surface disease index (OSDI), tear break-up time (TBUT), and optical coherence tomography (OCT) at diagnosis, on the day of surgery, and at two weeks postoperatively. Methods: A prospective observational study was conducted on 71 patients undergoing cataract surgery at Saint Barbara Hospital Trauma Center, Sosnowiec, Poland, from June 2022 to May 2023. Patients were randomly assigned to a test group (moisturizing eye drops) or a control group (no preoperative eye drops). The OSDI, TBUT, and OCT were evaluated at the baseline, preoperatively, and postoperatively. Results: The test group showed a significant improvement in OSDI scores (preoperative: 6.34 vs. baseline: 11.81; p < 0.001), which further decreased postoperatively (3.30; p < 0.001). TBUT also significantly increased from baseline to the preoperative visit (6.20 s to 7.97 s; p = 0.002) and remained stable after surgery (7.78 s). In contrast, the control group demonstrated only a minimal postoperative change in OSDI (3.92 to 3.70; p > 0.05) and a significant postoperative decrease in TBUT (5.96 s to 5.69 s; p = 0.864). Only the control group showed a significant postoperative decrease in epithelial thickness in operated eyes (p = 0.021), whereas no significant changes were observed in the test group. Conclusions: The preoperative use of moisturizing eye drops significantly improves the tear film stability, ocular comfort, and epithelial integrity, leading to better postoperative outcomes in cataract surgery patients.

Background: Orbital floor blowout fractures (OFBF) can have serious consequences for the patient. Selecting the right treatment method and materials is essential. Krenkel’s maxillary sinus implant has been used successfully for more than 40 years in clinical practice. The aim of this study was to evaluate the long-term outcome of this implant compared to polydioxanone (PDS) sheets. Material and methods: This retrospective study examined a cohort of 82 OFBF patients over a seven-year period. Clinical and geometric data were collected. Defect size, location, and the volume of the herniated tissue were measured from conventional computer tomography (CT) or cone beam computer tomography (CBCT) scans. The relationship between ophthalmologic rehabilitation and treatment modality was analyzed using logistic regression. Results: The study included 82 patients, 28% female and 72% male, with a median age of 45.2 years. Defect size and hernia volume correlated with preoperative ophthalmological symptoms. At follow-up, 14.8% in the implant group and 28.6% in the PDS group showed mild visual impairment, with no severe diplopia. Conclusions: Our results suggest this method is a reliable and effective solution for repairing OFBFs and ophthalmologic rehabilitation. However, further research in a clinical controlled trial is needed. Full article

Objective: Various orbital conditions (trauma, autoimmune thyroid disease, tumors, infections, congenital malformations) may lead to a consecutive increase in orbital cavity pressure resulting in orbital compartment syndrome (OCS). OCS is associated with acute loss of visual function and a high risk of permanent damage to the optic nerve (compressive optic neuropathy). Orbital decompression surgery (ODS) is a time-critical procedure that reduces pressure on the optic nerve, thereby improving visual function. The surgical management protocol for orbital decompression is not standardized and varies. Surgical techniques differ in orbital fat decompression, lateral canthotomy, and decompression of the medial orbital wall and floor. This retrospective study aims to evaluate surgery procedures and the outcome of visual function after orbital decompression surgery. Methods: In this retrospective study, we evaluated 28 patients (17 male, 11 female) with orbital compartment syndrome from May 2016 to October 2024. All patients underwent orbital decompression surgery as first-line treatment. Visual acuity (VA), diplopia, and ocular motility were analyzed pre- and postoperatively. Recovery was defined as postoperative improvement of vision, diplopia, and ocular motility. Linear and logistic regression analyses were used to assess the associations between clinically relevant risk factors and primary outcomes. Results: Orbital decompression surgery was performed with a median of 8.40 h (Q1: 4.80, Q3: 24.00) upon occurrence of symptoms. The average preoperative measured VA (logMAR) of the affected eye was 1.0. A total of 46% of the patients were preoperatively categorized as ”blind“ according to the WHO visual impairment categories. A total of 96% of the patients showed preoperative ocular motility impairment. Diplopia was preoperatively present in 46% of the patients. After orbital decompression surgery, postoperative visual acuity improved in 36% of the patients. Ocular motility improved by 67% and diplopia by 62% after ODS. The primary surgery technique was two-wall decompression in 68% (19/28) of the cases, followed by one-wall decompression (21%; 6/28), and three-wall decompression (11%; 3/28). Lateral decompression (82%; 23/28) and medial wall decompression (93%; 26/28) were the primary procedures performed. Orbital floor wall decompression was performed in only 14% (4/28) of the cases. Regression analysis revealed a statistically significant effect of preoperative measured vision on postoperative vision, while accounting for age, sex, and time to surgery. Conclusions: Orbital decompression surgery is the time-sensitive first-line treatment of acute visual function loss in OCS. Our data showed a postoperative improvement in visual acuity in 36% of the patients, along with considerable improvement rates in diplopia and ocular motility. The primary surgery technique was a two-wall decompression approach with lateral wall decompression and medial wall decompression. Center-specific timeline optimization of OCS patients is essential.

Background: Suture fixation of intraocular lenses (IOLs) is a rare but essential procedure for patients with inadequate capsular support, offering crucial therapeutic benefits. This study analyzes a large cohort of patients undergoing IOL suture fixation, focusing on demographics, risk factors, and clinical outcomes. Methods: In this retrospective analysis of 332 eyes treated at the Eye Center of the University Hospital Freiburg (2008–2022), we evaluated immediate and long-term postoperative outcomes, including visual acuity and refraction. The follow-up averaged 2.5 years. A detailed analysis of the IOL positioning was performed in 111 patients. Results: The most common indications were pseudoexfoliation syndrome (33%), trauma (17%), and prior complicated cataract surgery (11%). The Zeiss CT27SF lens was used most frequently (91%). The mean spherical equivalent deviation from target refraction was −0.375 diopters overall. According to the detailed analysis, IOL tilt occurred in 6.3% of patients, and decentration occurred in 7.2%. Only three patients (3.6%) required additional ocular procedures specifically for IOL repositioning. Risk factors for further surgery included underlying systemic conditions or multiple previous surgeries. Conclusions: Suture fixation of IOLs proves to be an adequate and effective intervention for visual rehabilitation in patients with compromised capsular support, demonstrating good refractive outcomes and low complication rates. Even in cases where the postoperative visual acuity was comparable to the best-corrected preoperative acuity, the procedure improved refractive correction by reducing the need for extensive refractive aids, such as contact lenses required for aphakia.

Background: Rhegmatogenous retinal detachment (RRD) is an ophthalmological emergency that can lead to vision loss if left untreated. Pars plana vitrectomy (PPV) is the preferred procedure for most complex RRD cases with a high success rate. However, certain parameters related to the patient, disease history, or ocular presentation may influence surgical outcomes. Methods: A systematic review of studies from 2010 to 2023 was conducted using PubMed/Medline (National Library of Medicine, Bethesda, MD, USA) and Scopus (Elsevier, Netherlands). The main objective of this review is to present the most significant data published in the scientific literature over the last 10 years, focusing on the latest implications of prognostic factors affecting the success of PPV in RRD. The search included terms such as “prognostic factors”, “visual outcome”, “functional outcome”, and “rhegmatogenous retinal detachment”. The database search returned 3489 studies. The included studies had to involve participants with RRD treated mainly by PPV, a minimum of 10 participants, and at least a 6-month follow-up period. Studies were excluded if they involved patients with previous PPV treatment or trauma. After reviewing their abstracts, titles, and applying the exclusion criteria, 19 articles were selected. Because it is an ample and interesting topic, many authors explored the connection between prognostic factors involved in the management of RRD and the final visual and functional outcomes. Methodological quality was assessed using PRISMA guidelines. Results: various factors have been studied, ranging from classic ophthalmological parameters, such as refractive error, axial length, lens status, visual acuity, duration of symptoms, description of the RRD, and retinal tears, to more complex findings on optical coherence tomography. Conclusions: The factors that significantly influenced postoperative prognosis in RRD included preoperative best-corrected visual acuity (BCVA), duration of symptoms, macular status (on/off), extent of retinal detachment, presence of macular hole, and proliferative vitreoretinopathy (PVR). Disruption of the ellipsoid zone (EZ), presence of epiretinal membrane (ERM), and lack of external limiting membrane (ELM) integrity were associated with poorer outcomes following RRD surgery.

Background: Artificial iris (AI) implantation is an innovative and increasingly utilized surgical procedure for injured eyes with iris trauma. Methods: A 76-year-old female and a 34-year-old male presented at the emergency department with a traumatic corneo-scleral laceration and perforated corneal ulcer, respectively. Emergency surgeries were performed to restore ocular integrity. In both cases, a modified surgical technique involving the implantation of an AI was performed; however, two different models of AI were used. Results: The AIs were sutured with four stitches directly to the scleral-fixated (SF) intra ocular lens (IOL), and the AI-IOL complexes were implanted, as a single unit, and fixated to the sclera using the lens haptics. Before and after the surgery, patients underwent a comprehensive eye examination, including a visual acuity test. The AI-SF IOL complexes remained well positioned, with no intraocular or extraocular complications observed during the follow-up evaluations of both patients. Conclusions: We reported a straightforward and repeatable modified surgical technique for two patients with two models of AI, both sutured to the SF IOL and fixated to the sclera, as a single unit. This approach may serve as an excellent alternative for managing aphakic eyes with extensive iridodialysis or partial aniridia. Full article

Background/Objectives: Cataract surgery has evolved into a refractive procedure aimed at optimizing both vision quality and quantity. Modern patients, particularly “baby boomers”, expect superior outcomes, increasing demand for premium intraocular lenses (IOLs). However, ocular surface dysfunction (OSD), especially dry eye disease (DED), compromises postoperative satisfaction, with up to 35% of patients dissatisfied despite achieving 20/20 visual acuity. This study aimed to characterize postsurgical ocular surface system failure (OSSF) and explore strategies to improve perioperative management. Methods: An open observational study was conducted at the Ophthalmology Complex Operative Unit, University Campus Bio-Medico, Rome, Italy, enrolling 20 patients with stage N2–3 and C1–2 lens opacities. Patients with diabetes, prior surgeries, or ocular inflammatory diseases were excluded. Preoperative and postoperative assessments included OSDI, SANDE scores, Schirmer test, TBUT, and fluorescein staining. Follow-ups occurred at 1 week, 1 month, and 3 months postoperatively. Statistical analysis used two-way ANOVA (p < 0.05). Results: Despite achieving a BCVA of 20/20, 44% of patients reported OSSF symptoms. Postoperative evaluations revealed significant worsening in OSDI and SANDE scores (p < 0.001), Schirmer test (preoperative mean 19.92 ± 10.06; p < 0.001), and TBUT (preoperative mean 5.88 ± 2.64 s; p < 0.001). Meibomian gland dysfunction and conjunctival hyperemia also worsened. Conclusions: Postsurgical OSSF results from neurogenic inflammation, tear film instability, and meibomian gland dysfunction, exacerbated by surgical trauma. Preoperative and postoperative management, including artificial tears, lid hygiene, and preservative-free regimens, are essential to improve outcomes and patient satisfaction. Comprehensive strategies can mitigate symptoms and enhance the benefits of cataract surgery. Full article

A macular hole is a defect of the neurosensory retina at the fovea. Post-traumatic holes can occur immediately after blunt trauma, causing severe non-penetrating retinal contusion or after sudden detachment of the vitreous from the retina. Post-traumatic macular holes can close spontaneously or may require vitreoretinal surgery. This paper aims to present the case of an 11-year-old boy with a macular hole following a ball injury. The child reported deterioration of visual acuity. Ophthalmic examination, ocular ultrasound, optical coherence tomography (OCT), perimetry, and a pattern visual evoked potential (VEP) test were performed. On the day of injury, the visual acuity of the right eye was 0.04 and intraocular pressure was 28 mmHg; the eyelid skin was reddened, and superficial conjunctival injection was observed. A fundus examination revealed oedema, pre-retinal haemorrhages, and a macular hole; peripheral retinal oedema in the superior temporal quadrant with pre-retinal haemorrhages was also seen. At the follow-up appointment scheduled 5 months following hospital discharge, visual acuity of the right eye was 0.3 and intraocular pressure was 20 mmHg. Follow-up OCT images of the OD macula were comparable to the findings obtained on the day of hospital discharge, i.e., 10 days after blunt trauma to the right eye. The left-eye OCT did not reveal any abnormalities. Full article

Introduction: 3D printing technology has gained considerable interest in the domain of orbital illnesses owing to its capacity to transform diagnosis, surgery planning, and treatment. This systematic review seeks to deliver a thorough examination of the contemporary applications of 3D printing in the treatment of ocular problems, encompassing tumors, injuries, and congenital defects. This systematic review of recent studies has examined the application of patient-specific 3D-printed models for preoperative planning, personalized implants, and prosthetics. Methods: This systematic review was conducted according to the PRISMA guidelines. The PICOS is “What are the current advances and applications of 3D printing for the management of orbital pathology?” The databases analyzed for the research phase are MEDLINE, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), ClinicalTrials.gov, ScienceDirect, Scopus, CINAHL, and Web of Science. Results: Out of 314 studies found in the literature, only 12 met the inclusion and exclusion criteria. From the included studies, it is evident that 3D printing can be a useful technology for the management of trauma and oncological pathologies of the orbital region. Discussion: 3D printing proves to be very useful mainly for the purpose of improving the preoperative planning of a surgical procedure, allowing for better preparation by the surgical team and a reduction in operative time and complications. Conclusions: 3D printing has proven to be an outstanding tool in the management of orbit pathology. Comparing the advantages and disadvantages of such technology, the former far outweigh the latter.

Purpose: Our aim was to investigate risk factors, clinical characteristics, and antibiotic susceptibility patterns of cornea-isolated Streptococcus species collected at a tertiary hospital in China over 18 years. Methods: This retrospective study reviewed data from 350 patients diagnosed with Streptococcal keratitis at Beijing Tongren Hospital between January 2006 and December 2023, including demographics, risk factors, clinical signs, in vivo confocal microscopy (IVCM) imaging, and antibiotic susceptibility testing. Results: The predominant type was Streptococcus pneumoniae (n = 108, 29.8%), followed by Streptococcus mitis (n = 90, 24.9%) and Streptococcus oralis (n = 85, 23.5%). Main risk factors included previous ocular surface disease (24.6%), ocular surgery (21.4%), and trauma (16.3%). Significant differences in clinical characteristics were observed among S. pneumoniae, S. oralis, and S. mitis regarding infiltration location (p = 0.038) and size (p = 0.037), as well as hypopyon presence (p = 0.006). IVCM revealed deeper inflammatory cell distribution and structural disruption as the disease progressed. Resistance rates of aminoglycosides, β-lactams, and fluoroquinolones have increased, with significant differences among species for amikacin (p = 0.010), gentamicin (p = 0.007), and others. Poor outcomes correlated with disease duration over one month, central corneal ulcers, dense infiltrations, hypopyon, and scar tissue presence on IVCM. Conclusions:Streptococcal keratitis is a complex ocular infection with multiple risk factors. S. pneumoniae, S. mitis, and S. oralis are the primary causative agents, exhibiting varying clinical features and antibiotic resistance patterns. Key factors associated with poor outcomes include long disease duration, central corneal ulcers, and severe infiltration. Full article

Purpose: We report the successful surgical treatment of a case of spontaneous complete anterior crystalline lens luxation in a patient affected by retinitis pigmentosa (RP), associated with elevated intraocular pressure and pupillary block. Additionally, we review the current literature regarding the association between ectopia lentis and RP. Case description: A 44-year-old female RP patient presented to our emergency department reporting severe ocular pain in her left eye (LE) and sickness. She had no history of ocular trauma and did not report systemic disorders. The best corrected visual acuity at presentation was 1/20 in her LE, the intraocular pressure was 60 mmHg, and slit lamp examination showed in her LE a complete dislocation of the lens in the anterior chamber, with mydriasis, atalamia, and a pupillary block. The patient had been administered intravenous mannitol 18% solution and dorzolamide–timolol eye drops and was hospitalized for urgent lens extraction. Anterior segment optical coherence tomography and ultrasound biomicroscopy were performed before surgery. Decompressive 23-gauge pars plana vitrectomy and phacoemulsification were performed, and the capsular bag was removed due to marked zonular weakness, with deferred intraocular lens implant. Conclusions: Acute angle closure glaucoma in patients with RP may be rarely caused by spontaneous anterior lens dislocation. To our knowledge, this is the first report of spontaneous anterior lens dislocation in an RP patient, documented through photographs, anterior segment optical coherence tomography, and ultrasound biomicroscopy.

A 25-year-old Caucasic female was referred to our clinic after suffering from infectious keratitis in the right eye for a month. The patient was a contact lens user and had no history of ocular trauma. Furthermore, the patient did not report any relevant antecedent. The main complaint was intense photophobia and pain. Infectious keratitis remains one of the main complications of contact lens wear and can become a therapeutic challenge in some patients. Although the most frequent causal agent is bacterial, other causes such as herpes virus, Acanthamoeba or fungi should be considered when antimicrobial therapy does not work as expected clinically. Fungal keratitis normally appears on previously damaged corneas, but it can also develop in contact lens wearers. Beauveria bassiana is an unusual pathogen which has been diagnosed more frequently lately per the clinical reports in the last 30 years, so it can be included in the diagnostic scheme when a fungal keratitis is suspected. In clinical management, AS-OCT may be a functional tool to assess the evolution and monitor the response to microbial agents and surgery. Although more studies are needed, some characteristic features have been described and can help to diagnose a fungal keratitis against other infections. AS-OCT can also play an important role in monitoring the corneal scarring after the keratitis episode, and it may be useful to plan post-infection therapy for visual rehabilitation. Full article

We present a case of endogenous endophthalmitis with urinary tract infection (UTI) caused by group B Streptococcus (GBS). An 86-year-old female initially presented with ocular pain and sudden visual disturbance of the left eye. The patient did not complain of other symptoms and had no history of recent ocular surgery or trauma. Endogenous endophthalmitis was clinically diagnosed based on ophthalmic examination, history, and lab results showing systemic infection. A few days later, GBS was identified in her aqueous humor, blood, and urine cultures. Intravitreal ceftazidime and vancomycin injections, as well as fortified ceftazidime and vancomycin eye drops, were used immediately after clinical diagnosis. However, the symptoms worsened despite repeated intravitreal injections, so evisceration was performed. Endogenous endophthalmitis caused by GBS is very virulent and may present without evident systemic symptoms. The early recognition of the disease and systemic work up, followed by prompt treatment, is necessary. Full article

(1) Background: Orbital wall fractures are common in maxillofacial trauma, and artificial implants are often used for reconstruction. However, there has always been concern about infection because implants are directly exposed to the airway. This study was conducted to determine the effectiveness of a combination of resorbable plates and antibiotic-impregnated collagen sheets in reconstructions of orbital fractures and to determine whether it had an effect in reducing postoperative antibiotic use. (2) Methods: The retrospective study was conducted on 195 patients who underwent orbital wall reconstruction from March 2019 to August 2022. The 176 patients in the control group underwent reconstruction using only resorbable plates and were administered postoperative antibiotics for 5 to 7 days. On the other hand, the 19 patients in the experimental group underwent reconstruction using a combination of resorbable plates and antibiotic-impregnated collagen sheets and only received antibiotics once before surgery. The occurrence of ocular complications, the length of hospitalization, the infection incidence rate, and the adverse effects of antibiotics were investigated. (3) Results: significant ocular complications were observed in the experimental group during a follow-up period of more than 1 year. Regarding postoperative infections, there were two cases of infection in the control group (infection rate: 1.14%), while no infection was found in the experimental group. The hospitalization period of the experimental group was significantly shorter than that of the control group (p < 0.01), and the incidence of total adverse effects of antibiotics, especially nausea, was lower in the experimental group (p = 0.02). (4) Conclusions: The combined use of resorbable plates and antibiotic-impregnated collagen sheets allows effective orbital wall reconstruction without infection, with a shorter hospital stay, and with fewer antibiotic adverse effects.

Background: Traumatic injuries in eyes previously treated with Deep Anterior Lamellar Keratoplasty (DALK) can lead to ruptures in the Descemet Membrane (DM) and damage to the corneal endothelium, a crucial layer for maintaining corneal clarity. Due to cell cycle constraints, the human corneal endothelium cannot proliferate; instead, it compensates for injury through cell enlargement and migration from adjacent areas. Methods: This study examines a notable case of corneal endothelial cell migration following a penetrating eye injury in a patient previously treated with DALK for keratoconus, supplemented by a review of relevant literature to contextualize the regenerative response. Results: A 39-year-old male with a history of DALK suffered a traumatic eye injury, resulting in damage to the Descemet Membrane and loss of the crystalline lens. After primary repair and considerations for further surgery, the patient’s cornea cleared remarkably, with an improved visual acuity. This demonstrates the DM’s potential for self-repair through endothelial cell migration. Conclusions: The outcomes suggest that delaying corneal transplant surgery for up to 3 months following Descemet Membrane injury due to ocular trauma could be advantageous. Allowing time for natural healing processes might eliminate the need for further invasive surgeries, thereby improving patient recovery outcomes. Full article
