Patient Presentation: A 23-year-old obese female was diagnosed with idiopathic intracranial hypertension (IIH) and referred to neurosurgery for ventriculoperitoneal shunt. A baseline ocular examination was performed prior to the procedure.
On examination, vision was 20/200 in the right eye, and 20/40 in the left eye. There was a right relative afferent pupillary defect. Slit lamp examination was normal.
A dilated fundus examination was performed demonstrating the following:

Contributor: Arshia Eshtiaghi (CC3)
Patient Presentation: A 45-year-old man presented with a 3-day history of painless blurred vision of his right eye. He had subjectively lost vision in his right eye 3 days prior to presentation, but regained most of his vision a few hours later. He denied any headache, flashes, floaters or field deficit during this acute, transient loss of vision episode. His past medical history includes hypertension that is not currently being treated.
He now reports that he sees "broken glass" through his right eye. On examination, his best-corrected visual acuity is 20/25 OD and 20/20 OS. IOP was within normal limits; there is no RAPD. Fundus examination is shown below:
Question 1: Describe what is seen on fundus examination.
To further investigate, OCT imaging of the right eye was performed and is shown below:
Question 2: Which of the following OCT abnormalities is most characteristic of this patient's condition?
Question 3: What is the value of performing OCT angiography as part of the workup?
Question 4: What is the treatment for PAMM?
