The authors report a case of a patient who underwent cataract surgery with implantation of a posterior chamber intraocular lens and presented endophthalmitis on the second postoperative day. She was treated with intravitreal injection of amikacin, vancomycin and dexamethasone. After resolution of the infection the patient presented macular infarction and important loss of visual acuity due to amikacin toxicity.

A2-Ai, Ann Arbor, Michigan.
Objective: To develop a population pharmacokinetic (PK) model to characterize serum pegcetacoplan concentration-time data after intravitreal administration in patients with geographic atrophy (GA) or neovascular age-related macular degeneration (nAMD).
Design: Pharmacokinetic modeling.
Participants: Two hundred sixty-one patients with GA or nAMD enrolled in 4 clinical studies of pegcetacoplan.

Department of Vitreoretina, Akhand Jyoti Eye Hospital, Mastichak, Saran, Bihar, India.
Purpose: To compare the anatomical and visual outcomes in eyes with submacular hemorrhage (SMH) treated with a combination of ranibizumab (RBZ) either innovator or biosimilar (Razumab) and intravitreal perfluoropropane gas (CF).
Methods: Treatment naïve neovascular age related macular degeneration (n-AMD) patients with SMH were retrospectively analyzed. Patients received either innovator or biosimilar RBZ (3 loading doses followed by pro re nata regimen) and single injection of intravitreal CF.

Background: To report a case of intraocular inflammation (IOI) after intravitreal injection of aflibercept 8 mg for treatment-refractory neovascular age-related macular degeneration.
Case Presentation: An 80-year-old man with diabetes mellitus had neovascular age-related macular degeneration refractory to treatment with aflibercept 2 mg. Despite ten injections of faricimab, the exudation remained, and we switched to brolucizumab, which resulted in a mild IOI.
Improving ROP management: insights from a comparative analysis of screening and treatment modalities in a tertiary hospital, Pakistan.

Institute of Ophthalmolohy, King Edward Medical University, Lahore, Pakistan.
Background: The principal objective of our study is to evaluate the characteristics of babies with type 1 ROP, screening practices and treatment trends in a tertiary care centre in Pakistan.
Methods: This prospective study at Mayo Hospital, Lahore (July 2022-July 2024), included 89 preterm infants with type 1 ROP, selected using non-probability sampling. Infants were categorized based on international (GA < 32weeks or BW < 1500 g) and local screening criteria (GA < 35 weeks or BW < 2000 g), and treatment outcomes were evaluated across three groups: Anti-VEGF, combination therapy (Anti-VEGF followed by laser), and laser therapy.

Due to its unique physiological structure and functions, the eye has received considerable attention in the field of Adeno-associated virus (AAV) gene therapy. Inherited retinal degenerative diseases, which arise from pathogenic mutations in mRNA transcripts expressed in the eye's photoreceptor cells or retinal pigment epithelium (RPE), are the most common cause of vision loss. However, current retinal gene therapy mostly involves subretinal injection of therapeutic genes, which treats a limited area, entails retinal detachment, and requires sophisticated techniques.
