Purpose: To evaluate photodynamic therapy (PDT) with verteporfin along with intravitreal ranibizumab in treatment of neovascular age-related macular degeneration.
Methods: This prospective interventional care series included 16 patients (17 eyes) of choroidal neovascularization secondary to neovascular age-related macular degeneration who were treated with PDT with verteporfin followed by an injection of 0.5 mg ranibizumab on the same day. The main outcome measures were best corrected visual acuity as recorded by both Snellen and Early Treatment Diabetic Retinopathy Study (ETDRS) charts (logMAR), contrast sensitivity (Pelli-Robson Chart), retreatment frequency, and frequency of side effects.
Results: Seventeen eyes underwent PDT with verteporfin and intravitreal 0.5 mg ranibizumab, following PDT. Patients were followed up every month for a total period of 6 months. Initial visual acuity ranged from CF to 20/32 and final acuity ranged from CF to 20/20. Visual acuity stabilized (gain/loss <2 lines) in 14 out of 17 eyes (82.35%) and improved in 3 out of 17(17.65%). Contrast sensitivity improved in 15 out of17 eyes (82.24%) There were no cases of ocular/systemic adverse events. Retreatment was required in only 2 out of 17 cases (11.76%) with a single injection of intravitreal ranibizumab.
Conclusion: The combination of PDT with intravitreal ranibizumab improves contrast sensitivity and stabilizes vision and reduces the number of retreatments, without significant ocular/systemic risks.

Purpose: To evaluate changes in the retinal microvasculature using widefield swept-source optical coherence tomography angiography (SS-OCTA) following three anti-vascular endothelial growth factor (anti-VEGF) loading injections for diabetic macular edema (DME).
Methods: Thirty-four treatment-naïve patients with DME received an initial three loading injections, followed by injections on an as-needed basis. Macular ischemia was evaluated based on the foveal avascular zone (FAZ) area, perfusion density, and vessel density on a 3 × 3-mm SS-OCTA image.

Purpose: To assess the risk of renal adverse events, particularly acute kidney injury (AKI), between intravitreal anti-vascular endothelial growth factor (anti-VEGF) agents.
Design: Meta-analysis.
Methods: A systematic literature search was conducted on Ovid Medline, Embase and the Cochrane Library for randomized controlled trials (RCTs) published from January 2005 to February 2024 involving adult patients receiving anti-VEGF intravitreal injections for agerelated macular degeneration, diabetic macular edema, and macular edema secondary to retinal vein occlusion.

To present a pediatric patient with a unique configuration of torpedo maculopathy complicated by macular choroidal neovascularization (CNV). A single case was retrospectively reviewed. An 8-year-old male child presented with decreased vision in the left eye and was found to have 2 distinct torpedo maculopathy lesions, 1 a smaller hypopigmented lesion in the temporal parafovea and the other a larger hyperpigmented comet-shaped lesion in the temporal periphery.

Purpose: The purpose of this study was o examine the optical coherence tomographic (OCT) characteristics of hyper-reflective foci (HRF) in patients with neovascular age-related macular degeneration (nAMD) and to assess the potential of HRF as a predictive factor for the development of macular atrophy following anti-vascular endothelial growth factor (anti-VEGF) therapy.
Methods: This was a retrospective analysis of 61 treatment-naïve eyes diagnosed with exudative AMD and type 1 macular neovascularization (MNV). The HRF was identified in the inner retina and outer retina layers, and the treatment response of HRF was documented.
