Visual Outcomes in Macula-Involving Retinal Detachments Based on Time to Surgical Repair

BACKGROUND AND OBJECTIVE: To examine the relationship between duration of macular detachment and postoperative visual acuity in macula-involving rhegmatogenous retinal detachments. PATIENTS AND METHODS: Retrospective review of patients who underwent surgical repair of macula-involving rhegmatogenous retinal detachments was conducted with Institutional Review Board approval. Primary outcome measure was postoperative best-corrected visual acuity (BCVA) as dependent on duration of macular detachment. RESULTS: In eyes with duration of macular detachment less than or equal to 7 days, postoperative BCVA increased by 0.017 logarithm of the minimum angle of resolution (logMAR) units (P = .001), and the odds of achieving logMAR 0 decreased by a factor of 0.43 (95% CI, 0.21 to 0.87; P = .02) with each additional day of detachment. Eyes repaired within 3 days of macular detachment were more likely to have postoperative BCVA of logMAR 0 than eyes repaired 4 to 7 days after macular detachment (odds ratio, 2.32; 95% CI, 1.15 to 4.70; P = .02). CONCLUSION: Increased duration of macular detachment is associated with progressive decline in postoperative visual acuity.
