Ocular involvement in allergic drug reactions.

Purpose Of Review: Many systemic medications have been observed to cause ocular toxicity. A subset of these reactions is thought to involve immunomodulation or a hypersensitivity reaction. As new medications are developed, ocular adverse effects are becoming increasingly prevalent. Herein we review immune-mediated drug reactions affecting they eye with special attention to the hypersensitivity mechanisms leading to ocular toxicity.

Recent Findings: Recent work has focused on mechanisms and risk of immune-mediated ocular adverse drug reactions including genetic susceptibility and loss of ocular immune privilege.

Summary: Given the consequences of immune-mediated ocular adverse drug reactions, clinicians must be aware of these to facilitate early recognition and management. The prompt involvement of an ophthalmologist for diagnosis and management is often essential to preserve vision and avoid long-term morbidity.
