A previously healthy 28-year-old man presents to the ED with pain in his left eye. The pain has developed over the past 4-6 hours and is made worse with moving his eye. He has also noticed that eye movements are associated with a sensation of flashing lights. He describes colours as being dull and an overall sensation of blurred vision.
On examination there is a diminished afferent pupillary response to light, a decrease in visual acuity, and a diminished central visual field (scotoma). The optic disc is however normal.
The patient describes a similar milder episode 8 months previously that resolved entirely in 2 days for which he did not receive any medical attention.
