Quantitative Analysis of Uveitis Macular Edema in Multiple Sclerosis Patients Receiving Deep Posterior Sub-Tenon Triamcinolone Acetonide Injection.

OBJECTIVE

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).

CONCLUSIONS

Posterior sub-Tenon injection of triamcinolone acetonide significantly improved visual acuity and decrease macular edema in patients with intermediate uveitis associated with multiple sclerosis.
