Study Overview
Brief Summary
Results of retinal detachment surgery may be affected in cases with history of previous intraocular surgery.
Detailed Description
Pars-plana vitrectomy for management of retinal detachment has favorable visual outcome with early intervention and development of small gauge instruments, cases with previous refractive surgery may be affected by other factors that may change the final visual outcome.
In this study, we aim to analyze the effect of refractive surgeries on the final visual outcome after vitrectomy for the management of retinal detachment.

Arms & Interventions
Vitrectomy group with previous refractive surgery
Cases with primary retinal detachment that are prepared for pars-plana vitrectomy with previous history of refractive surgery.
Intervention: Vitrectomy (Procedure)
Vitrectomy group with no previous intraocular surgery
Subjects with primary retinal detachment that are prepared for pars-plana vitrectomy with no previous history of intraocular surgery.
Intervention: Vitrectomy (Procedure)
Outcomes
Primary Outcomes
Visual acuity
Time Frame: Baseline and 6 months after surgery.
Changes in visual acuity from baseline and at the 6th month of follow-up measured by snellen chart and converted to logMAR units for statistical analysis.
Secondary Outcomes
- Corneal endothelial cells count(Baseline and 6 months after surgery.)
