History: A 48 year-old man was referred by his
optician because of multiple pigmented lesions in the left retina. The
vision was normal in both eyes and fundoscopy revealed multiple rounded
black lesions in the left superotemporal area. His father suffered from
bowel cancer. He underwent a colonoscopy which was unremarkable.
The pigmented lesions are congenital hypertrophy
of retinal pigment epithelium (CHRPE). They have no visual significance.
However, in a minority of patients these lesions may be associated with
familial polyposis coli which can lead to colorectal carcinoma. The association
occurs in the autosomal dominant condition called the Gardner's syndrome. |
