RESUMO
AIM: We aimed to analyze the effects of adjunctive posterior sub-Tenon capsule triamcinolone acetonide injection in the treatment of intermediate uveitis macular edema in multiple sclerosis patients that could not be controlled by systemic corticosteroid medications and immunomodulators. METHODS: The study included 30 eyes of 25 patients with multiple sclerosis who received a posterior sub-Tenon injection of 40 mg/mL triamcinolone acetonide. Parameters monitored for therapy efficiency were best-corrected visual acuity, intraocular pressure, central foveal thickness (CFT), and fluorescein angiography (FA) scores. RESULTS: Mean best-corrected visual acuity was significantly improved at the control visit 0.15 ± 0.10 versus baseline 0.40 ± 0.20 logMAR (p < 0.05). Six eyes showed intraocular pressure spikes requiring topical antiglaucomatous treatment. Mean CFT and FA scores were significantly decreased versus baseline (CFT: 345 ± 50 µm; FA score: 3.4 ± 1.0) compared with the 12-week control visit (CFT: 219 ± 35 µm; FA score: 1.6 ± 1.1; p < 0.001). CONCLUSION: Posterior sub-Tenon injection of triamcinolone acetonide significantly improved visual acuity and decrease macular edema in patients with intermediate uveitis associated with multiple sclerosis.
