Triple Therapy of Pars Plana Vitrectomy and Grid/Focal Laser for Diabetic Macular Edema (DME)
This study is designed to report 3-year result of triple therapy of vitrectomy, intravitreal triamcinolone and macular laser photocoagulation for intractable diabetic macular edema.
Previously author reported 1-year result(Am J Ophthalmol. 2007 Dec;144(6):878-885. Epub 2007 Oct 15.).

- Best-corrected visual acuity [ Time Frame: At baseline, 6,12,24,36 months after surgery ]Measurement of visual acuity at every visit. VA at every visit was compared from VA at baseline
- Central subfield macular thickness [ Time Frame: 0,6,12,24,36 months after surgery ]Automatically measured central subfield thickness from Stratus OCT

Procedure: Triple therapy of vitrectomy, IVTA and grid/focal laser photocoagulation
all pars plana vitrectomy were accompanied with removal of retinal Internal limiting membrane (ILM) around fovea in round fashion with a dimension of approximately 2 disc diameters.
IVTA was introduced at the end of surgery or on the next day (4mg in 0.1cc). Two weeks afterward, fluorescein angiography guided macular laser photocoagulation which consisted of direct photocoagulation on leaking microaneurysms and application of grid pattern laser was undertaken.
