To evaluate the influence of vitreous surgery performed for vitreous hemorrhage and traction retinal detachment (macular edema excluded) as a complication of diabetic retinopathy with or without ILM peeling on macular edema formation. Additionally to evaluate long-term spectral domain optical coherence tomography (SD-OCT) follow- up of macular structure.


101 eyes of patients, who had undergone vitrectomy were analyzed. 51 patients had vitrectomy with internal limiting membrane (ILM) peeling and 50 patients had vitrectomy without ILM peeling. Postoperative SD- OCT images were analyzed.

Effectiveness / Safety:

Mean preoperative visual acuity was 0.04 in the group qualified for vitrectomy with ILM peeling and 0.03 in the group qualified for vitrectomy without ILM peeling (no statistical difference). Mean follow- up was 19.8 months, and 17.8 months respectively. Postoperative visual acuity was 0.3 and 0.2 respectively. Central macular thickness was 228.5 µm and 258.8 µm respectively (no statistically significant difference).

Take home message:

Vitrectomy with or without ILM peeling may have a role in preventing macular edema in long-term follow-up.
