Outcomes

Primary Outcome Measures

Improvement in visual acuity
Visual acuity changes measured by snellen chart and converted to LogMar units.

Secondary Outcome Measures

Changes in metamorphopsia
Changes in metamorphopsia after surgery assessed by M-chart that is specially designed to subjectively assess metamorphopsia, each 1 millimeter deviation from reference line is considered significant deviation.

5. Study Description

Brief Summary
Management of primary retinal detachment due to upper retinal break is one of controversial situation that may face ophthalmologists in vitreoretinal subspecialty.
Detailed Description
There is no single surgical plan for management of primary retinal detachment due to upper retinal break, some surgeons prefer scleral buckling over vitrectomy in cases with no traction over the retinal break, others prefer to perform primary pars-plana vitrectomy with either air or gas tamponade. In this study we aim to compare the results of air and non-expansile gas tamponade in cases with upper retinal detachment with grade a or b proliferative vitreoretinopathy.
