Intraocular inflammation secondary to intravitreal brolucizumab treated successfully with Sub-Tenon triamcinolone: A...

To report on a case of successful treatment of intraocular inflammation (IOI) secondary to brolucizumab intravitreal injection that responded to a single sub-Tenon injection of triamcinolone.

An 81-year-old female with a longstanding history of exudative age-related macular degeneration (AMD) was unresponsive to various regimens of anti-VEGF injections. Her AMD was treated with one intravitreal injection of brolucizumab (6mg/0.05ml) into the right eye. On a follow-up visit, she had a new-onset conjunctival injection, with anterior chamber and vitreous inflammation, in the right eye, which was diagnosed as non-granulomatous iridocyclitis. The patient was treated with one posterior sub-Tenon injection of triamcinolone (40mg/ml) into the right eye. Subsequently, there was a durable resolution of inflammation, and her vision improved along with the resolution of her exudation.

This case suggests that some brolucizumab-related IOI episodes may be treated with posterior sub-Tenon triamcinolone. Further studies may serve to elucidate the role of sub-Tenon triamcinolone in brolucizumab-associated IOI.
