Purpose:: To evaluate the retinal vascularization process after intravitreal ranibizumab was administered to infants with aggressive posterior retinopathy of prematurity (AP-ROP).
Methods:: Twenty-six eyes of 13 infants with AP-ROP who received 0.25 mg intravitreal ranibizumab were retrospectively investigated. The patients were evaluated at weekly follow-up visits, and the findings were analyzed after retinal vascularization was complete.
Results:: The results showed regression in the AP-ROP of all the patients within the first 48-72 h. Average time for complete vascularization of the nasal quadrant (zone II) was postmenstrual week 45 (range 41-56), and vascularization of the temporal quadrant (zone III) was completed in the postmenstrual week 56 (range 50-65). Reactivation was observed in seven patients, on average at postmenstrual week 42; two of these patients underwent additional treatment. Two patients presented with avascular areas in the peripheral retina despite being 1 year old.
Conclusion:: These results showed that retinal vascularization following intravitreal ranibizumab was completed after a delay in patients with AP-ROP. Further studies are necessary to evaluate when and how vascularization occurs after intravitreal anti-vascular endothelial growth factor treatments.

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.

Purpose: To compare the efficacy of intravitreal antivascular endothelial growth factor (anti-VEGF) agents with oral carbonic anhydrase inhibitors (CAIs) in treating cystoid macular edema (CME) secondary to retinitis pigmentosa (RP).
Methods: This retrospective study analyzed 98 patients (98 eyes) with RP-CME: 47 (48.0%) received intravitreal anti-VEGF agents (Ranibizumab or Bevacizumab) and 51 (52.

Background: Intravitreal anti-vascular endothelial growth factor (VEGF) treatment for diabetic macular oedema (DME) may begin with several initial monthly doses. Characteristics, treatment patterns and outcomes were compared for eyes with DME that did and did not receive such initial doses.
Methods: This was a retrospective database study using American Academy of Ophthalmology Intelligent Research in Sight Registry data (01/01/15-31/12/20; index period).
