Intravitreal triamcinolone in cystoid macular edema due to uveitis and repeated surgery after a penetrating trauma.

摘要

PURPOSE: To test the effectiveness of intravitreal triamcinolone acetonide in treating macular edema due to multiple vitreoretinal surgical procedures and uveitis after a penetrating trauma with metallic foreign body retention in a 37-year-old man. METHODS: The patient received two intravitreal injections of triamcinolone acetonide-2 mg/0.05 mL and 4 mg/0.1 ml(-1) month apart. The 6-month follow-up included best-corrected visual acuity (BCVA) measurement and optical coherence tomography evaluation. RESULTS: After the first injection (2 mg) the foveal thickness (685 microm, as compared to a normal value of <165 microm) and the BCVA (20/200) remained unchanged with respect to the preinjection values; 1 week after the second injection (4 mg), the foveal thickness went down to 130 microm and the BCVA improved (20/80). Such results were unchanged at the 6-month control. No complications occurred. CONCLUSIONS: A 2 mg dose of triamcinolone acetonide did not improve the anatomic and functional status of the macula. A 4 mg dose markedly improved BCVA and reduced the macular thickness in this case of macular edema.
