Retinoblastoma

Medical Questions » Retinoblastoma
Name: Retinoblastoma
Also known as:
Cancer of the retina (light sensitive cells at the back of the eye) that usually occurs in children under three years of age.
Causes of Retinoblastoma
May be a familial (inherited tendency) in 40% of cases, but cause in others is unknown.
Symptoms of Retinoblastoma
The pupil becomes white, a squint is noticed, the affected eye bulges forward, becomes reddened and the vision is affected.
Tests for Retinoblastoma
Diagnosed by examining the eye with a magnifying light (ophthalmoscope) and a CT scan.
Treatment for Retinoblastoma
Small tumors may be treated by laser or chemotherapy (medication), but most are not diagnosed until large, and the eye must be removed.
Complications of Retinoblastoma of its treatment
May spread (metastasis) from the eye along the optic (vision) nerve to the brain.
Likely Outcome of Retinoblastoma
Depends on size of tumor at time of diagnosis. Survival rate with no spread is 85%, but this drops dramatically if cancer cells are found in the optic nerve. Overall five year survival about 70%.
