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:
Retina
Case 61
Patient Presentation: A 57-year-old male was referred to ophthalmology for blurry vision in his right eye over the past 3 days. The patient’s past medical and ocular history were unremarkable. On external examination, you noticed yellow papules which appear like cobblestones on the patients neck and arms. The patient has not seen a physician about these lesions. On assessment, his best-corrected visual acuity was 20/30-2 OD and 20/25-2 OS. Refraction was -0.75 sph OU. Fundus exam showed angioid streaks emanating from the optic disc OU and a small area of hemorrhage in the macula. The fundus drawings from the clinic visit are shown below:
OCT macula was performed and shown:
Right eye
Left eye
Question: What abnormalities are seen on the patient’s OCT image in the right eye?
Question: Given the clinical examination and imaging findings, what is the most likely cause for this pathologic process?
Question: What is the most likely systematic diagnosis in this patient?
Question: What is the best first-line treatment for this patient?
Our patient was treated with three injections of aflibercept in the right eye in monthly intervals. His vision improved to 20/25 and his OCT scan (shown below) demonstrated resolution of the CNVM with preservation of the outer retinal layers.
