Özet

Aim: To evaluate long-term macular changes following pars plana vitrectomy (PPV) with internal limiting membrane (ILM) peeling for diabetic macular edema (DME). Methods: Forty eligible eyes of 37 patients were included in this retrospective study. Best corrected visual acuity (BCVA), central macular thickness (CMT), and 5-mm macular volume (5-MV) were examined preoperatively, postoperatively after 1, 2, 3, 6, 12, and 24 months, and at a final visit. Response to surgical treatment was considered as recurrence, reincrease, or recovery of DME based on macular changes. Results: Mean follow-up time was 51.1 ± 19.0 months after surgery. Recurrence (n = 5) and reincrease (n = 17) of DME was observed in 22 eyes (55%) and additional treatments were applied. Recovery of DME was observed in 18 eyes (45%). Preoperative and final-visit mean BCVA (logMAR) was 1.08 ± 0.37 and 0.93 ± 0.45, respectively (p = 0.02). Preoperative and final-visit mean CMT was 514.74 ± 155.65 and 281.87 ± 112.58 μm, respectively (p 0.001). The 5-MV significantly decreased following surgery (from 8.18 ± 1.57 to 6.52 ± 1.39 mm p 0.001). DME was present in 12 eyes (30%) at the final visit. Conclusion: Although PPV with ILM peeling had efficacy in DME management, this effect tended to decrease over time, such that a considerable number of patients required additional treatment.
