Overview

Sclerochoroidal calcification occurs due to calcium deposition at the level of the sclera and choroid. It is typically idiopathic but it may be associated with abnormal calcium-phosphorus metabolism or renal tubular hypokalemic metabolic alkalosis syndrome. It is most often seen in older Caucasian males.

Funduscopic features include multiple discrete yellow placoid lesions typically found in the superotemporal post-equatorial retina.

OCT showed scleral elevations with compression of the overlying choroid and RPE abnormalities. The shape of the sclerochoroial calcification on OCT has been described in ‘mountain-like’ patterns including flat, rolling, rocky-rolling and table mountain.

FAF can show iso- or hyper- autofluorescence

B-scan ultrasound shows a hyper echoic area with posterior shadowing.
