Predictors for recovery of macular function after surgery for primary macula-off rhegmatogenous retinal detachment

Purpose To determine predictors of best-corrected postoperative visual acuity (VA) in patients who underwent surgical intervention for macula-off rhegmatogenous retinal detachment. Materials and methods Primary macula-off retinal detachments from the University of Colorado Primary Rhegmatogenous Retinal Detachment Database (2012–2017) were reviewed. The primary outcome measure was a postoperative VA of 20/40 or better at least 6 months after surgery. Patient demographics, medical history, duration of central vision loss before surgery, examination findings, operative technique, and postoperative findings were analyzed as possible predictors of postoperative visual recovery to 20/40 or better. Chi-square or Fisher’s exact test was used to compare categorical variables, and Wilcoxon rank sum test was used for continuous variables. A multivariable logistic regression analysis was used to determine the adjusted odds ratios and 95% confidence intervals for variables that were significant in the univariable analyses. Statistical significance was set at p
