A case of dilated and tortuous retinal vessels

Retinal Arteriole Abnormality

UK optometrist Akil Kanani brings forth another interesting case.

His 15-year-old WF presented in 2005 for her first eye examination whereby she was diagnosed with racemos hemangioma.  Her most recent examination was unremarkable with Best vision at 6/6 each eye with a minimal hyperopic refraction.

Augsburger et. al (1980) reports that retinal arteriovenous malformations such as racemos hemangioma are rare congenital occurrences that affect the vascular supply between the optic nerve head and the cortex.  Only one of these vessels are involved with their appearance mainly being dilated and tortuous.  It is rare that exudates or hemorrhaging will occur.
