Analysis of time to failure after retinal detachment surgery

Abstract

Purpose:To present the distribution of time to retinal redetachment in eyes undergoing retinal detachment surgery, using a method for adjusting time to outcome in eyes with silicone oil or heavy liquid tamponade ("oil-filled eyes").Methods:Data from two Australian centers were used. Adjusted time to outcome was measured from the date of tamponade removal in oil-filled eyes, unless failure was diagnosed with tamponade in situ.Results:188/1257 failures were identified (15.0%). Using unadjusted time to outcome, failures in oil-filled eyes occurred later than non-oil-filled eyes (median time to failure 57 vs. 28 days, P < 0.001). After adjustment, the distribution of time to failure was similar ..
