Malignant ocular neoplasm of childhood, with onset usually before the third year of life, composed of primitive retinal small round cells forming rosettes; the risk of developing osteosarcoma increases later in life. In familial cases, the disease is usually bilateral with multiple lesions within an eye, but in sporadic cases rarely so. Autosomal dominant inheritance caused by mutation in the tumor-suppressor retinoblastoma gene on chromosome 13q.
Stephan Schwartz
Stefan was born on 18 November 1994
He has always been very healthy and active. No problems other than the flu every now and then.
At the age of 13 (about 2½ years ago) he started complaining on a regular basis of headaches. He also complained about pain in his left eye. He took normal headache tablets, visited the GP a couple of times but all was treated with medication. This was on and off and went on for a couple of months.

Retina blastoma is eye cancer that can be diagnoses just before the 3 years age. Most of the time it will affect both eyes or sometimes one eye. Like they say on the internet these tumours are vitreous seed and are very difficult to be treated.
Tara Rynkiewicz


Tara was diagnosed with Retinal Blastoma when she was 9 months old, in her left eye. Her left eye was enucleated when she was 7 months old. We saw her for the first time in July 2006 when she was 9 weeks old. We fitted her first prosthesis shortly thereafter.
