'Photopsia' describes the symptom of visual disturbances that are typically flash-like, sudden in onset and brief, and occurring without light entering the eye. Patients reporting photopsia often pose a diagnostic challenge, given the wide range of possible neurological and ophthalmological causes. We review the common causes of photopsia, discuss the assessment and workup of this symptom, and stress the importance of close interdisciplinary liaison to help with its diagnosis and management. We discuss a patient with acute zonal occult outer retinopathy to illustrate these points.

Review
BACKGROUND
Photopsia is a relatively common symptom reported by patients in primary eye care settings. Although there are many possible etiologies, photopsia (light flashes) is usually associated with one of the following: (1) posterior vitreous detachment, (2) migraine with aura, (3) migraine aura without headache, and (4) retinal break or detachment. Each of these clinical conditions has symptoms and physical findings that will usually render the diagnosis apparent.
METHODS
It is important from a clinicolegal standpoint that specific procedures be performed to differentially diagnose the responsible condition and deliver appropriate follow-up care.

A 30-year-old woman presented with intermittent photopsia, a temporal visual field defect below the horizontal in her left eye, and flu-like symptoms. Slit-lamp and fundus examinations were unremarkable. Humphrey 30-2 threshold perimetry and 120-point screening visual field demonstrated blind spot enlargement of the left eye and a normal field in the right eye. Fundus autofluorescence, optical coherence tomography of the macula, full-field electroretinogram, electrooculogram, and multifocal electroretinogram were normal. Swept-source optical coherence tomography scan of the left optic nerve showed an intact outer retina, a remarkably thinned nerve fiber layer nasally, and peripapillary vitreous traction. Goldmann kinetic perimetry revealed a sector-shaped dense defect breaking out from the blind spot to the temporal periphery just below the horizontal in the left eye. The patient had nasal hypoplasia of the optic nerve and peripapillary vitreous traction.
