Question 1: What is the main finding of the OCT macula images above?
Question 2: Based on the patient history, fundus photos, and OCT images, what is the most likely diagnosis?
Question 3: What is the most common gene implicated in CACD?
One-year later, the patient presented with further decreased vision in the right eye. Visual acuity was 20/60 OD and 20/40 OS. Fundus photos and OCT macula images were taken and are shown below:
Question 4: Describe the OCT images above
To characterize the changes seen on fundus photography and OCT imaging, an OCT angiography was taken and confirmed a new choroidal neovascular membrane OD:
Question 5: What is the best treatment for this patient's new CNVM?
Understand the OCT findings in central areolar choroidal dystrophy.
