Case 14

Patient Presentation: A 14-year-old asymptomatic female presented to clinic for routine eye exam. Visual acuity was 20/25 -1 OD and 20/25 -2 OS. Examination demonstrated iris transillumination defects and nystagmus. Fundus examination demonstrated blond fundi with absent foveal light reflex. OCT Macula OU were performed and shown below.

Question: What is the main abnormality seen on the patient’s OCT images?

Question: What is this patient’s most likely diagnosis?

Question: How would you grade the foveal hypoplasia in this patient?

Question: What findings are NOT commonly associated with foveal hypoplasia?

Question: How should this patient be managed?
