Title

Relaxing retinectomy in the management of retinal detachment complicated by proliferative vitreoretinopathy

Purpose	To review the anatomical and functional results of relaxing retinectomies in non-traumatic retinal detachment (RD) complicated by proliferative vitreoretinopathy (PVR).
Methods	In this retrospective study, we reviewed the outcome of 39 consecutive eyes that underwent relaxing retinectomies for RD complicated by PVR between 2002 and 2010 and with a minimum follow-up of 6 months.
Results	The 39 patients underwent a mean number of 2,15 vitreoretinal surgeries before retinectomy was performed (range 0-4). Mean preoperative visual acuity (VA) was 0,12. One patient had LP only. Prominent features of the surgery included membrane peeling, use of perfluorocarbon liquid (76,92%), relaxing retinectomy (mean size : 141,67°) and intraocular tamponade with silicone oil (94,88%), C3F8 (2,56%) or SF6 gaz (2,56%). Complete retinal reattachment was achieved in 100% of cases at the end of the procedure. Recurrent RD was documented in 18 patients (46,15%). Retina could be reattached by one additional surgery in 5 of these patients. Final success rate was 66,67%. Mean VA at the end of follow-up was 0,088, with a mean follow-up time of 35,15 months (range 6-92). Two patients had a final VA of LP and one other underwent an enucleation. Complications included ocular hypertension (17,95%), corneal decompensation (7,69%) and epimacular membrane development (15,38%). Three patients developed neovascular glaucoma due to chronic RD, and one of them had to be enucleated.
Conclusion	RDs complicated by PVR and in need of a relaxing retinectomy still carry a fair functional and anatomical prognosis.
