PURPOSE: To determine the relationship between time from symptom onset or presentation to repair and visual outcomes for macula-on and macula-off rhegmatogenous retinal detachment (RRD).
METHODS: We searched MEDLINE, EMBASE, and Cochrane Library for randomized controlled trials and observational studies comparing best-corrected visual acuity (BCVA) based on time to RRD repair. Study identifiers, baseline characteristics, intervention characteristics, and visual outcomes were extracted. We conducted a random effects meta-analysis. Sensitivity analyses included leave-1-out and influence analyses. Primary outcomes included mean difference (MD) in final BCVA, MD between preoperative and final BCVA (∆BCVA), and relative risk of final BCVA24 hours. Secondary outcomes assessed other time points.
RESULTS: Twenty observational studies reported on 1929 patients. Macula-off RRD repair in 0-3 days from symptom onset was superior to 4-7 days for final BCVA (MD -0.06 [95% CI -0.09, -0.03], P < .001) but was not different for ∆BCVA (P > .05). Macula-on repair in 0-24 hours from presentation was superior to >24 hours for final BCVA (MD -0.02 [95% CI -0.03, -0.01], P < .05) but was not different for ∆BCVA (P > .05).
CONCLUSIONS: Macula-off RRD repair in 0-3 days from symptom onset may have better final BCVA compared to repair in 4-7 days. Macula-on RRD repair in 0-24 hours of presentation may have better final BCVA compared to repair in >24 hours. These results were supported by moderate- and low-quality evidence, respectively, and may have been influenced by differences in baseline BCVA.
