[Pars plana vitrectomy for diabetic pseudophakic macular edema]

In retrospective study to evaluate the anatomical and functional results of pars plana vitrectomy (PPV) with peeling of the inner limiting membrane (ILM) on pseudophakic eyes with diabetic macular edema.

PPV with peeling of the ILM was performed in 5 eyes (5 diabetic patients) after cataract surgery with posterior chamber intraocular lens implantation. Group of patients enrolled 4 female and one male aged from 44 to 62 years (average 56.2 y.). 2 eyes had undergone focal fotocoagulation previously for clinically significant macular edema. The macular edema was diagnosed by clinical examination and by retinal fluorescein angiography from 3 to 8 months (mean 6 m.) after cataract surgery. Visual acuity (VA) and angiographic changes were monitoring.

In pseudophakic eyes with diabetic macular edema that underwent surgery, the angiography documented decrease of hyperfluorescens in all cases. VA improved in 3 eyes (80%) more than +2 lines of Snellen test, stabilized in one eye (20%). VA detoriated in one eye by -1 line of Snellen test.

Our results demonstrated that PPV with ILM peeling is effective surgical procedure on pseudophakic diabetic macular edema.
