Pars Plana Vitrectomy for Diabetic Pseudophakic Macular Edema

Overview

Purpose:
In retrospective study to evaluate the anatomical and functional resultsof pars plana vitrectomy (PPV) with peeling of the inner limiting membrane (ILM)on pseudophakic eyes with diabetic macular edema.Material and method: PPV with peeling of the ILM was performed in 5 eyes (5diabetic patients) after cataract surgery with posterior chamber intraocular lensimplantation. Group of patients enrolled 4 female and one male aged from 44 to62 years (average 56.2 y.). 2 eyes had undergone focal fotocoagulation previously for clinically significant macular edema. The macular edema was diagnosed byclinical examination and by retinal fluorescein angiography from 3 to 8 months(mean 6 m.) after cataract surgery. Visual acuity (VA) and angiographic changeswere monitoring.Results: In pseudophakic eyes with diabetic macular edema that underwentsurgery, the angiography documented decrease of hyperfluorescens in all cases.VA improved in 3 eyes (80%) more than +2 lines of Snellen test, stabilized in oneeye (20%). VA detoriated in one eye by -1 line of Snellen test.Conclusion: Our results demonstrated that PPV with ILM peeling is effectivesurgical procedure on pseudophakic diabetic macular edema.
