Focal choroidal excavation associated choroidal NV in patient with AS-May 2020

A 54-year-old male patient presented to our clinic with complaints of long-standing reduced vision in the left eye and metamorphopsia in the right eye for 1 month. Visual acuity was 9/10 in the right eye and 1/10 in the left eye. Intraocular pressures were 14 mmHg in the right eye and 14 mmHg in the left eye.  The multicolor image and fundus autofluorescence image of both eyes and OCT and OCTA images of the right eye are shown below. What is the diagnose in the patient’s right eye?

The answer to the question is ‘’ Focal choroidal excavation associated choroidal neovascularization in patient with angioid streaks’’. As a result of the lottery drawn among those who answered the question correctly, Mr. Duygu Yalınbas won this month’s book prize. Congratulations to him.

Angioid streaks is a retinal condition characterized by breaks and cracks in Bruch’s membrane. Angioid streaks appear as narrow, irregular lines deep to the retina configured in a radiating fashion emanating from the optic disc. Choroidal neovascularization is a common cause of vision loss in patients with angioid streaks.
