Brief summary
To evaluate changes in ACA induced by pars plana vitrectomy with SO 1000cs injection in vitreo-retinal surgery in phakic eyes using AS-OCT and changes in the IOP preoperatively, post-operatively and post-silicone oil evacuation.
Detailed description
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.
Interventions
DEVICEAS-OCT after vitrectomy
AS-OCT is a light based imaging technique of the anterior segment of the eye in this study it is used to measure the anterior chamber angle changes after pars plana vitrectomy.
