Peripheral Circumferential Retinal Detachment after Pars Plana Vitrectomy: Complications and Management

Abstract

Purpose: This study aimed to evaluate treatment outcomes and complications of peripheral circumferential retinal detachment (PCD) after successful vitrectomy. Methods: Eyes diagnosed with PCD after pars plana vitrectomy (PPV) were retrospectively reviewed. The patient demographic data, complications, management, and treatment outcomes were collected and analyzed. Results: The mean follow-up duration was 18.0 ± 11.9 months. BCVA ranged from light perception to 0.1 (median: counting fingers at 40 cm). Major complications included rubeosis iridis (seven eyes), vitreous hemorrhage (five eyes), hyphema (five eyes), corneal decompensation (three eyes), hypotony (two eyes), and neovascular glaucoma (two eyes). All eyes underwent peripheral retinectomy to remove the detached retina and release traction. Complete retinal reattachment was achieved in all eyes. The final BCVA ranged from hand motion to 0.1 (median: counting fingers at 30 cm). Conclusion: PCD may be associated with delayed-onset complications, causing severe loss of vision. Proper management, including peripheral retinectomy, may preserve visual function.
