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:
Paediatric Ophthalmology
Case 2
Patient Presentation: An 8-year-old asymptomatic male patient was referred by an optometrist for an atypical optic nerve OD. The patient denied visual field deficits, flashes or floaters. Visual acuity was 20/20 OU; IOP was WNL.
OCT RNFL and macula imaging was conducted and is shown below:
Question 1: What is the best description of the OCT macula?
The fundus findings are shown below:
Question 2: Based on the fundus photograph and OCT imaging, what is the most likely diagnosis?
Question 3: What is the urgent next step for this patient?
Question 4: What type of disease is this?
