OUTCOMES OF SURGERY IN PROLIFERATIVE VITREORETINOPATHY

Abstract

Aim: To present the anatomical and functional outcomes of surgery in cases of rhegmatogenous retinal detachment complicated (at presentation) by proliferative vitreoretinopathy (PVR).Material and methods: Retrospective study of the cases operated upon by a single surgeon between October 2012 and September 2014.Results: A total of 49 eyes of 49 patients had PVR at presentation (12 cases with PVR stage B, 21 with stage C and 16 with stage D). 82% had a VA ≤ 0.05 at presentation. Peripheral retinectomy was the primary surgery in 57% of cases. Reinterventions was required in 16.3% of the cases (silicon oil extraction was not considered reintervention). Although at the first postoperative examination 32% of eyes had an IOP > 21 mmHg without medication, only 8% retained a high IOP at the last visit. At the last visit 73.4% of eyes presented attached retina (an additional 6% had an attached macula under silicone oil, but sub retinal fluid in the inferior quadrants). A final VA ≥ 0.05 was recorded in 67.3% of eyes (of which half had VA ≥ 0.1) Conclusions: In cases presenting with retinal detachment complicated by PVR the possibility of reinterventions and the risk of intraocular hypertension should be considered. Unfortunately, even some cases with favorable anatomical outcome will not present ambulatory vision.
