Title	Diabetic maculopathy and vitrectomy
Abstract Nr.	252

Purpose	to evaluate the visual results and find out predictive factors of these results in vitrectomy for diabetic maculopathy.
Methods	this retrospective study is dealing with 46 eyes (42 patients) treated with vitrectomy for diabetic maculopathy and a 3 and/or 6-month follow-up. The main study parameters are pre-and postoperative distance and near visual acuities (VA), pre- and postoperative macular edema (ME) on OCT examination, the characteristics of the maculopathy with or without vitreomacular traction and epimacular membrane (EMM), thas is tractional or not, on biomicroscopic and OCT examinations, and those of the vitrectomy, with or without surgical PVD, EMM and ILM peeling.
Results	the maculopathy was tractional in 80% of the eyes. Surgical PVD was performed in 80%, EMM peeling in 43%, and ILM peeling for a certainty in 87% of the cases, respectively. At 6 months (44 eyes), distance and near VA had improved 2 or more lines in 39 and 50% of the cases, respectively, but ME had decreased in 68%. No correlation was found between VA improvement and selected surgical maneuvers performed during vitrectomy. Correlation was poor between the anatomical, that is ME regression, and the VA results of the vitrectomy.
Conclusion	at 6 months, the VA results of vitrectomy are disappointing in comparison with ME regression on OCT examination. Several confounding factors, such as previous and subsequent ME treatments, make guidelines about the surgical treatment of diabetic maculopathy difficult to establish, as shown in the litterature .
