Topiramate induced bilateral hypopyon uveitis and choroidal detachment: a report of two cases and review of literature
Abstract Background Topiramate (TPM) is a drug commonly used by neurophysicians and psychiatrists for a plethora of indications. Topiramate has been reported to induce acute angle closure glaucoma as an adverse effect. However, there is limited literature on Topiramate causing hypopyon uveitis and intense ocular inflammation. It is imperative for ophthalmologists as well as physicians to be aware of the potential sight threatening ocular adverse effects of Topiramate. We report 2 rare consecutive cases of severe hypopyon uveitis and choroidal detachments after using Topiramate. Case presentation Two patients presented with sudden onset of angle closure, bilateral hypopyon uveitis and choroidal detachments. On reassessing a detailed treatment history, it was found that both patient were taking oral Topiramate which had been started 2 weeks before the onset of ocular symptoms. The bilateral hypopyon and angle closure were considered to be induced by Topiramate and the drug was discontinued. The patients were started on oral and topical steroids which led to resolution of hypopyon uveitis and choroidal detachments. The visual acuity improved and the intraocular pressure also got normalised in both the cases. Conclusions Topiramate can lead to a bilateral hypopyon uveitis and severe ocular inflammation. An urgent cessation of topiramate along with topical and systemic steroids is required to prevent serious complications.
