Purpose: To describe intraocular pressure (IOP) changes after injection of subtenon triamcinolone (STT) during examination under anesthesia (EUA) for pediatric patients.
Methods: Multicenter, retrospective case series of pediatric patients STT from three tertiary care ophthalmic services between November 2018 and October 2023.
Results: Of 392 patients identified, 59 eyes of 41 patients (10.5%) were included. Laser was administered in 95.1% of the cases. STT dose ranged from 4 to 20 mg. The most common diagnosis was retinopathy of prematurity (43.9%). Two eyes (3.4%) of 2 patients (4.9%) were mild steroid responders. One eye (1.7%) of 1 patient (2.4%) was a moderate responder. There were no high steroid responders, and all eyes with steroid response showed a return of IOP to normal range at next visit without needing any IOP-lowering medications. No patients were diagnosed with glaucoma or required glaucoma surgery. Only 1 eye (1.7%) developed trace posterior subcapsular cataract, while no optic disc cupping or inflammation were noted.
Conclusions: Subtenon triamcinolone injection is commonly used to prevent inflammation at the time of retinal photocoagulation treatment in pediatric patients. It has a favorable safety profile in relation to IOP elevation and cataract formation. There was no requirement for IOP lowering medications or surgical interventions.
