Abstract
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 [...] Read more.
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

Abstract
Background: In this study, we compare the 12-month results of eyes that underwent ab externo, open-conjunctival XEN45 gel stent placement with mitomycin C (MMC) with and without the intraoperative addition of Ologen collagen matrix (XEN45 and XEN45 + Ologen groups, respectively). Methods: Intraocular [...] Read more.
Background: In this study, we compare the 12-month results of eyes that underwent ab externo, open-conjunctival XEN45 gel stent placement with mitomycin C (MMC) with and without the intraoperative addition of Ologen collagen matrix (XEN45 and XEN45 + Ologen groups, respectively). Methods: Intraocular pressure (IOP) measurements were recorded postoperation at 1 month, 3 months, 6 months, and 9 months, and 12 months, and IOP reduction, reduction in number of IOP-lowering medications, and success rate were compared between XEN45 and XEN45 + Ologen groups. A complete success was defined as a ≥20% drop from baseline IOP at 12 months without the use of medications and without any of the following: an additional procedure (e.g., needling), a recorded IOP ≥ 21 mm Hg at two consecutive visits, or the occurrence of catastrophic events (e.g., no light perception (NLP)). A qualified success was defined as an IOP reduction of ≥20% from baseline with the use of medications. We included 145 eyes with at least 1 month of follow-up data, 46 in the XEN45 group and 99 in the XEN45 + Ologen group. Of these, 113 eyes had 12 months of follow-up data comprising 41 XEN45 eyes and 72 XEN45 + Ologen eyes. Results: There were no significant differences in the IOP change from baseline between XEN45 and XEN45 + Ologen groups except at the 3-month postop timepoint (p < 0.05). At the 12-month follow-up, 41.5% (17/41) of XEN45 eyes and 52.8% (38/72) of XEN45 + Ologen eyes met complete or qualified success criteria. Conclusions: No significant differences in success rate and decrease in the number of IOP-lowering medications from baseline were identified between XEN45 and XEN45 + Ologen groups. Full article

Background: This study innovatively combines Artificial Intelligence (AI) algorithms with smartphone technology, automatically detecting the Near Point of Convergence (NPC) and diagnosing Convergence Insufficiency (CI) without the need for extra diagnostic tools and, notably, without having to rely on the subject’s vocal response, marking an unprecedented approach in the field to the best of our knowledge. Methods: This was a prospective study that enrolled 86 participants. The real-time tracking of eye structures and movements was conducted using AI technologies integrated with a mobile application (MobileS). Participants brought the smartphone closer, focusing on a target displayed on the screen. The system calculated pupillary distance (PD) and phone-to-face distance, incorporating a unique feature called the exodeviation episode’s counter (ExoCounter) to determine the NPC. Additionally, participants underwent testing using the RAF Ruler test (RulerT), considering the ground truth. Results: MobileS demonstrated significant correlation with the RulerT, as evidenced by a Pearson correlation coefficient of 0.74 (p < 0.001) and an Intraclass Correlation Coefficient (ICC) of 0.73 (p < 0.001), highlighting its reliability and consistency with conventional ophthalmic testing. Additionally, the system exhibited notable sensitivity and specificity in diagnosing CI. Notably, user feedback indicated a preference for the MobileS, with 71% of participants favouring it for its ease of use and comfort. Conclusions: MobileS is a precise, user-friendly tool for independent NPC measurement, applicable in tele-ophthalmology and home-based care. Its versatility extends beyond CI diagnosis, marking a significant advancement in ophthalmic diagnostics for accessible and efficient eye care. Full article

Objective: To report a case of ocular toxoplasmosis reactivation in a patient with neurosarcoidosis undergoing immunosuppressive therapy. Methods: Case report and literature review. Results: A 34-year-old male with neurosarcoidosis, treated with Infliximab and Mycophenolate Mofetil, presented with sudden visual decline in his left eye. Multimodal imaging revealed active chorioretinitis. Serological tests showed elevated Toxoplasma IgG levels with normal IgM levels. Treatment with oral corticosteroids and antibiotics led to significant improvements in vitreous turbidity and lesion inactivity at follow-up, despite unchanged visual acuity. Conclusions: This case highlights the risk of toxoplasmosis reactivation in immunosuppressed sarcoidosis patients. It emphasizes the importance of considering ocular toxoplasmosis even with normal IgM levels, and demonstrates the value of multimodal imaging in diagnosis and follow-up. Full article

Over 2.2 billion people across the globe face significant barriers to accessing essential ophthalmic care, with elderly, rural, and refugee populations being disproportionately affected, deepening existing disparities in eye care. Three-dimensional printing is a novel technology that has the potential to transform the field and improve access by alleviating many patient-specific barriers. This article delves into the evolution of 3D printing within ophthalmology, highlighting its current applications and future potential. It explores various 3D printing techniques and numerous biomaterials discussing their effectiveness in creating advanced solutions such as bioengineered corneas, ocular prosthetics, and innovative treatments for dry eye syndrome, from punctal plugs to lacrimal gland models. Additionally, 3D printing has revolutionized drug delivery systems for conditions like glaucoma, retinal diseases, and ocular brachytherapy. Whether through 3D printed contact lens-based drug delivery systems or polycaprolactone implants that biodegrade and provide sustained drug release without adverse effects, these systems hold immense potential in the field. Despite its promise, the integration of 3D printing into clinical practice presents challenges, which the article addresses alongside strategies for overcoming them. By mapping out the technological advancements and challenges, this review offers a roadmap for enhancing global eye care accessibility and improving patient outcomes on a global scale. Full article
