Advantages:

Photocoagulation is currently the most recommended therapy however, the prognosis after laser treatment for diffuse edema was worse than focal edema. Pars plana vitrectomy with ILM peeling appears to be beneficial in eyes with diffuse non-tractional diabetic macular edema, and its effectiveness is maintained long term.

Methods:

Retrospective study of 19 consecutives patients (21 eyes) with 24 months follow-up. Visual acuity and OCT scans were reviewed at 3, 12,24 months post operatively.

Effectiveness / Safety:

The mean preoperative macular thickness was 533+/- 133. The mean postoperative macular thickness was 400+/-169 at 3 months, 383 +/- 169 at 12 months and 363 +/-127 at 24 months. Final best-corrected visual acuity improved of 2 or more ETDRS lines in 43 % patients or stabilized in 19%.

Take home message:

Vitrectomy with ILM peeling appears to be beneficial in eyes with diffuse non-tractional diabetic macular edema, and its effectiveness is maintained long time.
