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:

Patient Presentation: An 11-year-old male was referred to ophthalmology for an abnormal retinal lesion in the left eye. The patient is asymptomatic. Visual fields are normal, and BCVA is 20/20 OU. Fundus exam was performed and is shown below:
Question: Where is the lesion in this eye?
OCT was performed over the lesion and shown below.
Question: What is the abnormality seen in the OCT?
Question: Based on the imaging and exam findings, what is the most likely diagnosis?
Question: What is the prognosis of a patient who presents with dark-without-pressure lesions?
