Abstract
Purpose :
To compare the rate of post-operative retinal detachment (RD) in patients who underwent macular surgery for epiretinal membrane (ERM), full thickness macular hole (FTMH), or vitreomacular traction (VMT).
Methods :
A single-center, retrospective chart review of all patients who underwent macular surgery for ERM, FTMH, or VMT between 1/1/2015 and 6/1/2022. Patients who developed subsequent RD were included in the analysis. Those with a history of RD before macular surgery were excluded.
Results :
The overall rate of RD after macular surgery was 1.13% (127/11256) in 127 eyes of 127 patients. The rates of post-operative RD were 1.87% (7/374) for VMT, 1.15% (54/4680) for FTMH, and 1.06% (66/6202) for ERM (p=0.348).
Pre-macular surgery, mean (SD) log MAR [Snellen] visual acuity (VA) was 0.827 (0.598) [20/134]. VA was similar between the three groups (p= 0.555). RD developed 228.72 ± 407.22 days (range: 2 to 1912 days) after macular surgery. Pre-RD surgery mean (SD) log MAR VA 1.288 (0.886) [20/388] was also similar between the three groups (p=0.496). Mean follow-up duration was 1239 ± 851 days.
Single surgery anatomic success (SSAS) rate at 3-months was 87.4% (111/127): 87.0% (47/54), 90.9% (60/66), and 57.14% (4/7) for MH, ERM, and VMT respectively (p= 0.038). SSAS rate at final follow-up visit was 75.6% (96/127): 77.8% (42/54), 75.8% (50/66), and 57.1% (4/7) for MH, ERM, and VMT, respectively (p= 0.489). SSAS with pars plana vitrectomy (PPV) was 70.0% (70/100), while with PPV/scleral buckle (SB), it was 100% (18/18), 66.67% (2/3) with pneumatic retinopexy, and 100% (6/6) with laser (p=0.023). Re-detachment occurred 126.6 ± 149.5 days (range: 9 to 654 days) after primary RD repair. Final reattachment rate was 98.4% (125/127).
Conclusions :
Currently, there is no significant difference in the rate of postoperative RD between PPV for ERM, VMT, and FTMH.
