Abstract
Purpose
To identify prognostic factors for visual acuity and anatomic outcomes associated with giant retinal tear management using intraoperative perfluorocarbon liquids.
Methods
All patients with giant retinal tears without proliferative vitreoretinopathy (PVR) who underwent management with intraoperative perfluorocarbon liquids between 1994 and 2005 were re-viewed.
Results
The study included 115 patients (117 eyes), 93 (80.9%) males and 22 (19.1%) females, with a mean age of 30.3±15.2 years. Mean follow-up period was 29.7±26.7 months. Success rate with primary procedure was 78.6%, which increased to 94% with multiple surgeries. On univariate analysis, factors significantly associated with final visual acuity better than 20/200 included phakic/clear lens at presentation (p=0.0113), partial retinal detachment (p=0.0233), absence of all postoperative complications (p=0.0122), absence of recurrent retinal detachment (p=0.0406), and absence of postoperative PVR (p=0.0062). Logistic regression analysis highlighted that phakic/clear lens at presentation, unfolded flap of the giant tear, absence of postoperative cataract, and absence of post-operative PVR were associated with final visual acuity better than 20/200. On univariate analysis, use of gas tamponade was significantly associated with recurrent retinal detachment (p=0.0190). Logistic regression analysis highlighted that placement of an encircling scleral buckle and use of silicone oil tamponade were associated with anatomic reattachment with primary procedure.
Conclusions
Encircling scleral buckling and silicone oil tamponade decrease the risk of recurrent retinal detachment.
