Management of primary retinal detachment due to upper retinal break is one of controversial situation that may face ophthalmologists in vitreoretinal subspecialty.
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.
