### Diagnosis
- **Eye Examination**: A detailed examination of the eye by an ophthalmologist.
- **Imaging Tests**: Ultrasound, MRI, or CT scans to determine the size and extent of the tumor.
- **Genetic Testing**: To determine if the retinoblastoma is hereditary and to assess the risk for other family members.
### Treatment
- **Chemotherapy**: To shrink the tumor, often used in combination with other treatments.
- **Radiation Therapy**: Targeted radiation to destroy cancer cells.
- **Laser Therapy**: Photocoagulation to destroy blood vessels feeding the tumor.
- **Cryotherapy**: Freezing treatment to destroy cancer cells.
- **Surgery**: In severe cases, removal of the affected eye (enucleation) may be necessary to prevent the spread of cancer.
### Prognosis
- **Early Detection**: When detected early, retinoblastoma is highly treatable, and the prognosis is generally good.
- **Follow-Up Care**: Regular follow-up is crucial to monitor for recurrence and to manage any long-term effects of treatment.
### Prevention
- **Genetic Counseling**: For families with a history of retinoblastoma, genetic counseling and testing can help identify carriers of the RB1 gene mutation and inform decisions about family planning and early screening for children.
If you have specific concerns or symptoms related to retinoblastoma, consulting a healthcare professional is essential for proper diagnosis and treatment.
