Non-hereditary retinoblastoma is a type of eye cancer that occurs in children and is not caused by an inherited gene mutation. It is caused by a mutation in the retinoblastoma gene that occurs spontaneously in the developing eye. This type of retinoblastoma is usually diagnosed at an early age and is often treatable with surgery, radiation, and chemotherapy.

The most common symptom of non-hereditary retinoblastoma is a white pupil (leukocoria) in one or both eyes. Other symptoms may include:

- Eye redness

- Eye pain

- Poor vision

- Crossed eyes (strabismus)

- Abnormal eye movements

- Swelling of the eye

- Dark spots in the retina

- Headaches

- Nausea

- Vomiting

Non-hereditary retinoblastoma is caused by a mutation in the RB1 gene, which is a gene that helps control cell growth and division. This mutation can occur spontaneously or be caused by environmental factors such as radiation, certain chemicals, or viruses.

1. Laser therapy: This treatment uses a laser to destroy the cancer cells in the eye.

2. Cryotherapy: This treatment uses extreme cold to freeze and destroy the cancer cells.

3. Radiation therapy: This treatment uses high-energy X-rays to kill the cancer cells.

4. Chemotherapy: This treatment uses drugs to kill the cancer cells.

5. Surgery: This treatment removes the cancerous tissue from the eye.

6. Photocoagulation: This treatment uses a laser to seal off the blood vessels that are supplying the cancer cells with nutrients.

Yes, there are treatments available for non-hereditary retinoblastoma. Treatment options include laser therapy, cryotherapy, radiation therapy, chemotherapy, and surgery. The type of treatment used will depend on the size and location of the tumor, as well as the age of the patient.
