 Abstract
Purpose: We investigated the long-term outcomes of vitrectomy with internal limiting membrane (ILM) peeling as treatment for myopic traction maculopathy (MTM).
Methods: The medical records of patients who underwent vitrectomy to treat MTM were retrospectively evaluated. We excluded patients who exhibited macular holes (MHs) or retinal detachment at the time of primary surgery. The best-corrected visual acuity (BCVA) and central foveal thickness (CFT) were analyzed preoperatively, at 3, 6, 12, and 24 months after surgery, and at the final visit. Complications including retinal detachment or an MH were noted during follow-up.
Results: Twenty-three eyes of 22 patients were enrolled. At the time of primary surgery, the mean patient age was 64.4 ± 11.1 years and the baseline mean logMAR BCVA and CFT, 0.67 ± 0.50 and 431.8 ± 159.5 μm, respectively. The mean follow-up peri- od was 53.7 ± 19.3 months. The mean logMAR BCVAs at 3, 6, 12, and 24 months postoperatively and at the final visit were 0.42 ± 0.39 (p = 0.001), 0.41 ± 0.38 (p = 0.001), 0.39 ± 0.40 (p < 0.001), 0.42 ± 0.43 (p < 0.001), and 0.51 ± 0.47 (p = 0.016), respectively, thus significantly better than the baseline value. The mean CFT at 3, 6, 12, and 24 months postoperatively and at the final visit were 244.6 ± 72.3, 210.5 ± 79.1, 209.6 ± 91.6, 219.8 ± 93.9, and 217.7 ± 81.3 μm, respectively, thus significantly less than baseline (all p < 0.001). MTM resolved in 18 eyes (78.3%) after primary surgery, without any complication, and remained stable to the final visit.
Conclusions: Vitrectomy with ILM peeling afforded favorable long-term efficacy and safety in MTM patients.
