Over the past decade, intravitreal injections of anti-VEGF agents have been widely used and intensively developed as a treatment option for many ophthalmological indications. Due to its availability and low cost, the most frequently used...

Diabetic retinopathy (DR) and diabetic macular edema (DME) remain major causes of vision loss among working-age adults. Artificial intelligence (AI), particularly deep learning, has gained attention in ophthalmic imaging, offering opportunities to improve both diagnostic accuracy and efficiency. This review examined applications of AI in DR and DME published between 2010 and 2025. A narrative search of PubMed and Google Scholar identified English-language, peer-reviewed studies, with additional screening of reference lists. Eligible articles evaluated AI algorithms for detection, classification, prognosis, or treatment monitoring, with study selection guided by PRISMA 2020. Of 300 records screened, 60 met the inclusion criteria. Most reported strong diagnostic performance, with sensitivities up to 96% and specificities up to 98% for detecting referable DR on fundus photographs. Algorithms trained on optical coherence tomography (OCT) data showed high accuracy for identifying DME, with area under the receiver operating characteristic curve (AUC) values frequently exceeding 0.90. Several models also predicted anti-vascular endothelial growth factor (anti-VEGF) treatment response and recurrence of fluid with encouraging results. Autonomous AI tools have gained regulatory approval and have been implemented in clinical practice, though performance can vary depending on image quality, device differences, and patient populations. Overall, AI demonstrates strong potential to improve screening, diagnostic consistency, and personalized care, but broader validation and system-level integration remain necessary.

Purpose: To analyze the retinal and choriocapillaris changes in diabetic patients with no or with early signs of diabetic retinopathy using high-definition (HD) angio optical coherence tomography angiography (OCTA) software and spectral-domain (SD) OCT. Methods: A total of 112 eyes (54 eyes from 27 diabetic patients and 58 eyes from 29 control subjects) were included in this retrospective cross-sectional study of healthy and diabetic adults. Retinal microvascular changes were assessed by using HD-OCTA software to calculate vascular density (VD) and foveal avascular zone (FAZ). SD-OCT was used to assess retinal thickness and volume in parafovea as well as ganglion cell complex (GCC) parameters. Results: The VD-whole image was significantly higher in the healthy control group (MW z = 1109.5, p = 0.012; t = 2.611, p = 0.010). Also, VD-parafovea was significantly higher in the healthy subjects (MW z = 1053.5, p = 0.004; t = 3.207, p = 0.002). GCC focal loss volume (FLV) was significantly decreased in diabetic patients (p = 0.051). Non-flow FAZ did not show a statistically significant difference between groups, although the FAZ was larger in the diabetic patients. Conclusions: Diabetic patients with no or early signs of diabetic retinopathy have decreased VD compared to healthy individuals. They also present retinal changes at the GCC that are correlated with initial neurodegeneration. HD-OCTA and SD-OCT can detect vascular changes and structural signs of retinal neurodegeneration before clinically apparent diabetic retinopathy. Potentially, these methods may offer new biomarkers for monitoring disease progression and visual prognosis.

Fuchs endothelial corneal dystrophy (FECD) is the most common corneal endothelial dystrophy. It is characterized by the progressive loss of corneal endothelial cells (CECs), guttae formation on the Descemet membrane, and corneal edema, leading to visual impairment. Corneal transplantation remains the standard treatment, but it has limitations such as donor shortages, infection risk, and graft rejection. Rho-kinase (ROCK) inhibitors have emerged as a promising pharmacological alternative. These agents promote CEC proliferation, migration, and adhesion while inhibiting apoptosis and enhancing corneal endothelial wound healing. Several studies have demonstrated the efficacy of ROCK inhibitors in improving corneal clarity and endothelial function, particularly when used as an adjunct to Descemet Stripping Only (DSO) surgery. Additionally, they show potential in preventing corneal edema in FECD patients undergoing cataract surgery. The methodology involved a literature search through the PubMed and Medline databases using relevant keywords. Only peer-reviewed articles in English were included, with additional references from selected articles reviewed to ensure comprehensive coverage. ROCK inhibitors offer a novel pharmacological approach to managing FECD. They have shown potential in promoting endothelial cell regeneration and improving corneal functIion. Despite promising results, further research is required to determine ROCK inhibitors’ long-term safety, optimal dosing, and efficacy in surgical and non-surgical FECD patients. Their potential to delay or prevent corneal transplantation represents a significant advancement in FECD management.

Advanced periorbital basal cell carcinomas may necessitate orbital exenteration and consequent vision loss, which significantly reduces patients’ life quality. Orbital reconstruction is a demanding surgical procedure due to the complex orbital anatomy and vital structures located in the orbit. In this report, we presented an 83-year-old patient with advanced basal cell carcinoma that had expanded into the orbit. An orbitotomy was performed to remove the tumor completely while preserving the eye function. Orbital reconstruction was performed by a standard surgical method using a titanium mesh modeled according to a natural phantom skull. This maintained the eye function and achieved satisfactory facial esthetics.

Objective: To report a rare case of bilateral iris metastasis from small cell lung carcinoma (SCLC) and systematically review the literature on SCLC-associated iris metastases, with emphasis on clinical presentation, management, and outcomes. Materials and Methods: A systematic literature review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. PubMed, ScienceDirect, Scopus, and Web of Science were comprehensively searched on 10 July 2025. Eligible studies included English-language reports of iris metastasis originating from SCLC in human subjects. Case report: A 58-year-old woman with previously treated SCLC developed bilateral iris metastases one year after complete remission of the primary tumor. Ophthalmic examination revealed whitish-gray, vascularized iris masses with iridocorneal angle involvement, associated with secondary angle-closure glaucoma and markedly elevated intraocular pressure (48 mm Hg) in the left eye. Cyclocryotherapy, preceded by systemic and topical antiglaucoma therapy, resulted in pain relief and a reduction in intraocular pressure; the patient died four months later due to pneumonia. Results (Systematic Review): Seventeen studies comprising 17 patients were included; the median age was 60 years, and 64.7% were male. The median interval from SCLC diagnosis to ocular presentation was 4 months, although iris metastasis was occasionally the initial or concurrent manifestation of disease. The most common presenting features were visual impairment (58.8%), ocular pain (41.2%), and elevated intraocular pressure (41.2%), while iris neovascularization (35.3%) and synechiae (29.4%) were also frequent. Bilateral involvement was reported in only one previous case. Treatment approaches were heterogeneous and included antiglaucoma therapy, systemic chemotherapy, local radiotherapy, anti-VEGF therapy, and enucleation. Among patients with available follow-up (n = 12), 58.3% died within a median follow-up of 7.5 months. Conclusions: Bilateral iris metastasis from SCLC is rare and may occur as a manifestation of recurrent disease after remission. It is an aggressive condition characterized by nonspecific ocular symptoms, variable management, and poor survival, underscoring the importance of early recognition and the need for evidence-based diagnostic and therapeutic strategies.
