Zoledronate-induced acute anterior uveitis: a three-case report and brief review of literature

Abstract

Purpose: This three-case report aims to highlight the ocular adverse effects induced by bisphosphonate therapy and to call clinicians' attention.

Methods: Three cases of acute anterior uveitis secondary to the initial dose of zoledronate infusion were reported with focus on their symptoms, treatment regimens, and outcomes. A review of published reports provided a basis for discussion.

Results: Three cases of acute anterior uveitis were either bilateral or unilateral. They demonstrated typical manifestations of bisphosphonate-induced acute anterior uveitis such as eye pain, blurred vision, conjunctival and ciliary hyperemia, keratic precipitates, and flare in the anterior chamber. After topical corticosteroid-containing comprehensive treatments, these symptoms resolved completely without any vision loss and long-term sequelae.

Conclusions: Acute anterior uveitis may be part of the acute phase reaction induced by zoledronate. Patients should be informed of its symptoms in advance and be monitored closely during and after administration. Clinicians should have a good awareness of the zoledronate-associated acute anterior uveitis and to treat it in a prompt and appropriate manner.
