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%. |
