PURPOSE: To report the efficacy of intravitreal injection of triamcinolone acetonide(TA) for cystoid macular edema remaining after vitreous surgery. METHODS: Eight eyes of 7 patients aged from 32 to 84 years old were studied. The original diseases that caused macular edema were central retinal vein occlusion in 2 eyes, branch retinal vein occlusion in one eye, Irvine-Gass syndrome in 2 eyes, and diabetic retinopathy in 3 eyes. 4 mg of TA was injected intravitreally and visual acuity and foveal thickness measured by optical coherence tomography(OCT) were evaluated in before and after the surgery. RESULTS: Macular edema resolved rapidly after injection of TA in all cases and cysts were extinguished or diminished. The foveal thickness in OCT was reduced significantly from preoperative 495 +/- 116 (mean +/- standard deviation) microns to 267 +/- 117 microns after one week, and 246 +/- 81 microns after one month. The effect persisted for three months. Visual improvement of more than two Snellen lines was seen in 4 eyes. No side effects were observed except a temporary increase of intraocular pressure in one eye. CONCLUSION: Intravitreal injection of TA is effective in a short-term for cystoid macular edema remaining after vitrectomy.
