Purpose To evaluate the outcomes of perfluorocarbon liquid (PFCL) versus posterior retinotomy (PR) during Pars plana vitrectomy (PPV) for Rhegmatogenous retinal detachment (RRD), focusing on anatomical success, visual acuity, intraocular pressure (IOP), and complications.

Methods This is a prospective randomized controlled trial that included 58 eyes with RRD, divided into Group A (PFCL, n = 29) and Group B (PR, n = 29). Preoperative assessments included best-corrected visual acuity (BCVA), IOP, axial length, lens status, macula status, and PVR grade. Outcomes were evaluated at 1 week, 1 month, 2 months, and 3 months postoperatively. Primary outcomes included retinal reattachment rates and the number of operations; secondary outcomes included BCVA, IOP changes, complications like cataract development, retinal redetachment, epiretinal membrane (ERM) formation, and single-surgery success.

Inclusion criteria:

A clear diagnosis of primary RRD requiring surgery, 18 years or older, The potential to return for follow-up visits for at least 6 months post-surgery.

Exclusion criteria:

When presented with tractional or exudative retinal detachment, had surgery on the affected eye in the past, presented with severe eye disorders like advanced glaucoma or endophthalmitis.
