Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Abstract Introduction Ocular hypertension and secondary glaucoma are relatively common and serious complications in silicone filled eyes which may end in blindness. Reports have described the percentage of incidence to be within 3 - 30 % of silicon filled eye which are complicated with secondary glaucoma. \[1\] Aim of study Evaluation of changes in anterior chamber angle and intra-ocular pressure (IOP) in patients with rhegmatogenous retinal detachment (RRD) who underwent pars plana vitrectomy (PPV) with silicone oil (SO) 1000cs tamponade and after silicone oil evacuation.

Population The study was a prospective interventional study. The study included 30 eyes from 30 patients with rhegmatogenous retinal detachment (RRD) who are going to undergo PPV with SO injection. The study was conducted at Ophthalmology department, Minia University Hospital in Egypt between April 2023 and April 2024.
