Subtenon Triamcinolone Acetonide Injection with Topical Anesthesia in Pediatric Non-Infectious Uveitis

Subtenon triamcinolone acetonide (Kenalog®; Bristol Myers Squibb) (STA) injections are commonly used in the treatment of adults in an outpatient setting. However, publications on detailing its outpatient use, safety, and efficacy in the pediatric population are scarce.

We reviewed STA injections performed in children in the outpatient clinics at two tertiary centers from 2014 to 2020. All children were aged ≤ 18 years and had a diagnosis of non-infectious uveitis. STA injections were done using 0.5 cc (20 mg) triamcinolone injected superotemporally with only topical anesthesia. Data on the efficacy and safety of STA in treating inflammation and compiled data on visual acuity improvement and incidence of ocular complications were evaluated.

Forty-eight eyes in 30 patients were included. The mean age of patients was 13.1 (range 7-18) years. There were no immediate complications observed in all injections performed. At the 3-month follow-up, inflammation had improved in 85.4% of eyes, macular edema had resolved in 77.8% of eyes, and there was significant vision improvement after STA. At 6 months after STA, the incidence of ocular hypertension was 12.5% and no new cataracts had developed.

STA injection with topical anesthesia was a well-tolerated, reasonable alternative for short-term treatment of uveitis among this pediatric population.
