The primary outcome was the final attachment rate and single surgery anatomic success (SSAS) at 3 months after RD repair.Results A total of 210 eyes were analysed—70 in the delayed RD group and 140 in the acute RD group. SSAS was 58/70 (82.9%) for the delayed RD group and 112/140 (80%) for the acute RD group (p=0.71). At the time of RD diagnosis, mean (SD) logarithm of minimum angle of resolution visual acuity (VA) was 0.51 (0.70) (Snellen, 20/65) in the delayed RD group vs 1.04 (0.92) (Snellen, 20/219) in the acute RD group (p<0.001). Mean VA was better at 1 and 3 months post-repair in the delayed RD group (p=0.005 and 0.041, respectively) but similar by 6 months, 12 months and at the final visit post-repair (p=0.48, 0.27, and 0.23, respectively).Conclusions Delayed-onset RDs occurring ≥6 weeks after initial presentation to a retina specialist with an acute PVD generally had better VA at the time of RD diagnosis and faster post-surgical visual recovery compared with acute-onset RDs diagnosed at the initial presentation. No significant difference in anatomic outcomes was seen between the two groups.Data are available upon reasonable request.
