Abstract PURPOSE: The authors studied the efficacy of intravitreal triamcinolone acetonide in a case series of patients with diffuse diabetic macular edema without evidence of vitreous-macular traction refractory to laser photocoagulation. METHODS: Six eyes with clinically diffuse diabetic macular edema that failed to respond to at least two previous sessions of laser photocoagulation were included. The mean age of selected patients was 72.5+/-13.8 years, with a preoperative best-corrected visual acuity reduced to 1.48+/-0.18 logMar and a mean baseline intraocular pressure (IOP) of 15.17+/-2.64 mmHg. The authors also studied macular thickness measured by optical coherence tomography (OCT 2000 scanner, Humphrey Instruments, San Leandro, CA) - in the preoperative period it was 640.8+/-171.1 microm - and the fluorangiographic (Heidelberg Retina Angiograph, Heidelberg Engineering GmbH, Heidelberg, Germany) patterns, which showed pooling in tardy phases and leakage. Mean follow-up was 4 months. RESULTS: In each patient the authors observed a significant improvement, both functionally and anatomically. Mean best-corrected visual acuity increased in the postoperative period to 0.94+/-0.53 logMar. No patient showed decline of visual acuity at the end of follow-up. Base line macular thickness was reduced in the postoperative period to 312.2+/-157.65 microm measured by OCT and fluorangiographic patterns showed a reduction of pooling and of leakage. The most common complications described in the literature were not observed and the increase of mean IOP in the postoperative period to 18.76+/-5.72 mmHg was not significant. CONCLUSIONS: Intravitreal triamcinolone acetonide may decrease macular edema and improve visual acuity in eyes with diffuse diabetic macular edema.
