A 6-year-old spayed female American Cocker Spaniel presented with episcleritis in the right and then theleft eye (OS) at eight month interval. Repeated intralesional triamcinolone acetonide was administered subconjunctivallyto both eyes (OU). During this period, scleral ectasia was revealed on ocular funduscopy OS and then confirmedon ultrasonography and computed tomography. A year later, conjunctival hyperemia occurred around remnanttriamcinolone particles and was treated by resection of these particles in the OU. A recurrence of episcleritis, whichdid not regress, required repeated triamcinolone subconjunctival injections four months later in the OU. Four monthsafter these injections OU, the dog was presented with bilateral conjunctival mass, which had developed over the previousmonth. The round-shaped masses with diameters of 1 cm were surgically resected from exposed scleral ectasia lesionof thin and bulging scleral surface in the OU. The cross-section of both masses showed a white-colored accumulationat the center and triamcinolone induced granulomas enclosing necrotic tissue were confirmed by impression cytologyand histopathological examination.
