The hallmark of retinoblastoma is leukocoria which is an abnormal appearance of the retina as viewed through the pupil, also known as amaurotic cat's eye reflex. A positive family history of retinoblastoma may be present. Less common symptoms of retinoblastoma include deterioration of vision, a red and irritated eye, eye pain, squint, proptosis and fever.

Overview

The hallmark of retinoblastoma is leukocoria, which is an abnormal appearance of the retina as viewed through the pupil, also known as amaurotic cat's eye reflex. Common symptoms of retinoblastoma include strabismus and proptosis. The clinical presentation depends on the stage of the disease.
