Name of the Condition
- Malignant neoplasm of unspecified choroid
- Also known as choroid cancer or intraocular melanoma of the choroid
Summary
This condition represents a type of eye cancer found in the choroid, the vascular layer of the eye between the retina and the sclera. It is a rare but serious form of cancer that can impact vision and overall eye health.
Causes
The exact cause is unknown, but genetic mutations in eye cells are suspected. Some cases are linked to environmental factors like UV radiation exposure.
Risk Factors
- Age, as it is more prevalent in older adults.
- Light eye color may be a predisposing factor.
- A family history of eye cancers or other forms of melanoma.
Symptoms
- Blurred vision or vision loss.
- Seeing flashes of light or shadows.
- A noticeable dark spot on the iris.
- Pain or redness, rarely, if the condition advances.
Diagnosis
Comprehensive eye examinations are performed. Imaging tests such as ultrasound, MRI, or CT scans may be used. Biopsy may be conducted in some cases to confirm malignancy.
Treatment Options
- Radiation therapy, often the primary treatment, aims to destroy cancer cells.
- Surgical options like enucleation (removal of the eye) if the tumor is large and threatens sight or life.
- Laser therapy or photocoagulation may be used to treat smaller tumors.
Prognosis and Follow-Up
Prognosis depends on the tumor size, location, and whether it has spread. Regular follow-up with an ophthalmologist is essential to monitor for recurrence or metastasis.
Complications
- Vision loss or blindness.
- Metastasis to other parts of the body, such as the liver.
- Glaucoma or cataracts due to tumor growth.
Lifestyle & Prevention
- Protect eyes from excessive UV exposure by wearing sunglasses.
- Maintain regular eye examinations, especially if at higher risk.
- Avoid smoking, as it may increase cancer risk.
When to Seek Professional Help
Seek immediate medical attention if experiencing sudden vision changes, persistent eye pain, or new dark spots in the eye.
