Outcomes of Retinectomy without Lensectomy in Eyes with Rhegmatogenous Retinal Detachments with Proliferative Vitreoretinopathy

Abstract

Purpose : To report the anatomic and functional outcomes of retinectomy without lensectomy in eyes with rhegmatogenous retinal detachment (RRD) and proliferative vitreoretinopathy (PVR).

Methods : A retrospective review of patients treated with vitrectomy and retinectomy without lensectomy from January 1^st 2015 to January 1^st 2020 was performed. The primary outcome was the final attachment rate and single surgery anatomic success (SSAS) 3 months after retinectomy. Secondary outcomes included predictors of final visual acuity, the mean number of subsequent operations required for complete retinal reattachment, incidence of cataract surgery, and number of eyes that ultimately had successful silicone oil removal (SOR).

Results : Complete final retinal reattachment was achieved in 111/112 eyes (99.1%), with a mean (SD) follow-up of 29 (14) (range, 8-62) months after retinectomy. The 3-month SSAS was achieved in 84/112 eyes (75%). The final visual acuity improved or stabilized in 76/112 (67.9%) eyes. Silicone oil removal was performed in 72 of 112 patients (64.3%) during the study period, and cataract surgery was performed on 101 (90.2%) eyes before the last follow-up visit.

Conclusions : Retinectomy without lensectomy to repair RRDs complicated by PVR demonstrated anatomic and functional results that were comparable to historical reports of retinectomy with lensectomy. This study suggests that removing the lens when there is no significant cataract may not be necessary in these cases to obtain reasonable outcomes.
