Coats disease is an eye disorder characterized by abnormal development of the blood vessels in the retina (retinal telangiectasia). Most people begin showing symptoms in childhood. Early signs and symptoms vary but may include vision loss, “crossed eyes” (strabismus), and a white mass in the pupil behind the lens of the eye (leukocoria). Over time, Coats disease may also lead to retinal detachment, glaucoma, and clouding of the lens of the eye (cataracts). In most cases, only one eye is affected. Coats disease is not inherited and the underlying cause is not known. It has been theorized that some cases may be due to somatic mutations (acquired, not inherited) in the NDP gene. Treatment depends on the symptoms present and may include cryotherapy and laser photocoagulation (alone or in combination), steroids for inflammation, and/or surgery for retinal detachment.
