A Case of Incidental and Uncomplicated Subretinal Triamcinolone Acetonide

Posterior subtenon injection of triamcinolone acetonide (PSTA) is commonly done to treat refractory cases of macular edema. Complications may arise from the procedure as well as from the use of the periocular steroid medications. Side effects include subconjunctival hemorrhage, progression of cataract, scleral perforation (resulting in subretinal, subhyaloid, or intravitreal injection of the drug), retinal detachment, ptosis, orbital fat prolapse, orbital abscess, infectious scleritis, ocular hypertension, and scleral abscess. Here we describe a case of inadvertent subretinal triamcinolone acetonide (TA) deposition from a PSTA procedure without any adverse vision-threatening outcomes.
