Retinoblastoma is a rare malignant neoplasm (cancer) that starts in the immature retina (the light-sensitive lining of theback of the eye) of babies. affecting both eyes in about 25 per cent of cases. Retinoblastoma results from a genetic disorder that may be inherited or may arise from a new mutation. The condition usually becomes obvious before 2 years of age. The affected eye may be blind and lead to the development of a squint, or the white tumour may be seen through the pupil.

If retinoblastomas are diagnosed and treated before they spread outside the eyeball, more than 90 percent can be cured. Treatment may be by surgical removal of the eye, by destroying the blood supply to the tumour, or by radiotherapy. Some sight can usually be preserved in one eye. Genetic counselling is available for people who have had retinoblastoma and might plan to have children, so that they can assess the risks. Genetic testing of infants of affected families will identify those who carry the gene so that early diagnosis and treatment are possible.

Some patients may receive chemotherapy drugs that help kill or slow the growth of cancer cells. Some drugs are taken by mouth, while others are injected into a vein using a syringe or an intravenous (IV) drip device. Because these drugs affect the entire body, they may help treat cancers that have spread beyond the eyes. However, retinoblastoma is often resistant to chemotherapy. Therefore, different combinations of drugs may need to be used to effectively treat the cancer. Clinically, many chinese herbs are very good for patients who have had retinoblastoma chemotherapy.
