Abstract
Purpose This is the first study reported in the United Kingdom to investigate the efficacy and safety of posterior, sub-Tenon's triamcinolone acetonide injections in the treatment of posterior and intermediate uveitis.
Methods Twenty-eight posterior sub-Tenon's triamcinolone injections (40 mg) were given and the results analysed with a 6 month prospective follow-up in 13 cases.
Results At 6 weeks follow-up, objective improvement in visual acuity occurred in 25 eyes (p < 0.05). Vitreous cellular activity was diminished in 21 eyes (p < 0.05). In most cases improvement was observed within 2 weeks of injection. No patient required repeat triamcinolone injection within 3 months and all patients previously treated with systemic immunosuppression were able to decrease or discontinue this treatment. Complications included transient elevation of intraocular pressure in 4 patients and persistent mild ptosis in 2 patients.
Conclusions We have demonstrated that posterior sub-Tenon's triamcinolone injection significantly decreases cystoid macular oedema, with a corresponding increase in visual acuity, in patients with posterior uveitis. Systemic immunosuppression may be reduced or discontinued with the avoidance of associated systemic side effects, and the technique has a high level of patient acceptability.
