INDUCIBLE TRANSIENT CENTRAL RETINAL ARTERY VASOSPASM: A CASE REPORT.

Objective: To report a case of inducible transient central retinal artery vasospasm with associated imaging.

Methods: Observational case report.

Results: A 51-year-old man presented for outpatient follow-up for recurrent inducible transient vision loss in his right eye. He experienced an episode during examination and was found to have central retinal artery vasospasm. Fundus photography and fluorescein angiography obtained during his vasospastic attack confirmed retinal arterial vasospasm. Treatment with a calcium-channel blocker (nifedipine) has been effective in preventing recurrent attacks.

Conclusions: Idiopathic primary vasospasm is a rare cause of transient vision loss that is difficult to confirm because of the transient nature. We obtained imaging showing the initiation and resolution of the vasospastic event. The patient was then successfully treated with a calcium-channel blocker.
