A Stereotyped Syndrome with Retro-Ocular Pain, Photophobia, and Visual Disturbance Masquerading as Optic Neuritis: Case Series

ABSTRACT

We describe here a case series of six patients referred to the Neuro-ophthalmology service in Sheffield, UK with possible acute unilateral optic neuritis. Each patient had a triad of unilateral photophobia, ipsilateral retro-ocular pain, and ipsilateral loss of vision. All patients had normal ocular examinations and investigation findings with no objective structural or functional abnormalities identified. Patients were treated by weaning-off regular analgesia and, where appropriate, commencing migraine prophylaxis. In the three patients with complete recovery of pain, there was also complete recovery of vision. We propose that this is a migraine syndrome and that the decreased visual acuity is a functional consequence of the pain and photophobia.
