Materials and Methods: 40 eyes of 22 patients, which were diagnosed with uveit and treated with PSTT in our clinic, are included in this study. Before and after PSTT treatment visual acuity on 1^st, 3^rd and 6^th months, complications such as vitritis, retinal vasculitis or changes in cystoid macular oedema (CMO), increase in intraocular pressure (IOP) and cataract progression were recorded. Success of treatment was evaluated with clinic and angiographic regression for CMO and vasculitis. Vitritis was followed with biomicroscobic examination. Wilcoxon test was used for statistical analysis.
Results: 40 eyes of 22 patients were followed for average 18.2 months (6-21 months). Included patient in study; Grup A: Idiopathic, Grup B: Behçet, Grup C: Pars planit for üveitis. When results were examined, PSTT efficiency found; CMO was observed in 40% of the patients at the beginning and was observed 20% in the 1^st month, 20% in the 3^rd month and 10% in the 6^th month, vitritis was observed in 100% of the patients at the beginning and was observed 10% in the 1^st month, 10% in the 3^rd month and 0% in the 6^th month and vasculitis was observed in 10% of the patients at the beginning and was observed 0% in the 1^st month for Group A. CMO was observed in 60% of the patients at the beginning and was observed 40% in the 1^st month, 30% in the 3^rd month and 30% in the 6^th month, vitritis was observed in 90% of the patients at the beginning and was observed 40% in the 1^st month, 0% in the 3^rd month and vasculitis was observed in 10% of the patients at the beginning and was observed 10% in the 1^st month and 0% in the 3^rd month for Group B. CMO was observed in 50% of the patients at the beginning and was observed 0% in the 1^st month and vitritis was observed in 100% of the patients at the beginning and was observed 0% in the 1^st month, for Group C. The effect of PSTT treatment on visual acuity was; 0.36 at the beginning and 0.48, 0.50, 0.49 at the 1^st 3^rd and 6^th months respectively for Group A, 0.53 at the beginning and 0.60, 0.56, 0.56 at the 1^st 3^rd and 6^th months respectively for Group B and 0.40 at the beginning and 0.48, 0.49, 0.49 at the 1^st 3^rd and 6^th months respectively for Group C. During the follow-up period intraocular pressure was observed over 21mmHg on 2 eyes (5%). With topical antiglaucoma treatment, IOP was taken under control. On 3 eyes (7.5%) cataract progression was observed.
Conclusion: PSTT treatment is found effective to contain posterior segment inflammation of uveits. Keywords : Uveitis, subtenon, triamcinolone acetonide
