Causes & Risk Factors
Several factors can contribute to Malignant Melanoma of Eye.
Eye melanoma develops when melanocytes in the eye undergo genetic mutations that cause them to grow and multiply uncontrollably.
Eye melanoma develops when melanocytes in the eye undergo genetic mutations that cause them to grow and multiply uncontrollably. These pigment-producing cells are normally responsible for giving the eye its color, but when they become malignant, they form tumors that can interfere with vision and potentially spread to other organs. The exact trigger for these cellular changes remains largely unknown to medical researchers.
Unlike skin melanoma, eye melanoma shows no clear connection to ultraviolet light exposure or sunburns.
Unlike skin melanoma, eye melanoma shows no clear connection to ultraviolet light exposure or sunburns. This puzzles scientists because the same type of cells that cause sun-related skin cancer behave so differently when located inside the eye. Some research suggests that certain genetic factors may predispose individuals to developing this cancer, but no definitive hereditary pattern has been established.
The cancer most commonly arises in the uveal tract, particularly the choroid, which supplies blood to the retina.
The cancer most commonly arises in the uveal tract, particularly the choroid, which supplies blood to the retina. Less frequently, melanoma can develop in the conjunctiva (the clear membrane covering the white of the eye) or the iris (the colored part of the eye). Environmental factors, chemical exposures, and viral infections have been studied as potential causes, but none have shown consistent links to eye melanoma development.
Risk Factors
- Light-colored eyes, especially blue or green
- Fair skin that burns easily
- Age over 50 years
- Caucasian ethnicity
- Male gender
- Certain inherited skin conditions
- Abnormal skin pigmentation around the eye
- Occupational exposure to welding or UV lights
- Previous history of skin melanoma
- Certain genetic mutations
Diagnosis
How healthcare professionals diagnose Malignant Melanoma of Eye:
- 1
Diagnosing eye melanoma typically begins when an ophthalmologist notices an unusual growth during a routine eye exam or when a patient reports vision changes.
Diagnosing eye melanoma typically begins when an ophthalmologist notices an unusual growth during a routine eye exam or when a patient reports vision changes. The doctor will perform a comprehensive eye examination using specialized instruments to look inside the eye, including ophthalmoscopy and slit-lamp examination. These tools allow clear visualization of the retina, choroid, and other internal eye structures where melanomas commonly develop.

Several advanced imaging tests help confirm the diagnosis and determine the tumor's size and location.
Several advanced imaging tests help confirm the diagnosis and determine the tumor's size and location. Ultrasound of the eye provides detailed images of masses inside the eye and measures tumor thickness, which helps determine treatment options. Fluorescein angiography involves injecting a dye into the bloodstream and photographing how it flows through eye blood vessels, revealing abnormal circulation patterns around tumors. Optical coherence tomography creates high-resolution cross-sectional images of the retina and underlying layers.

Unlike many other cancers, eye melanoma is rarely diagnosed through biopsy because removing tissue samples from inside the eye carries significant risks to vision.
Unlike many other cancers, eye melanoma is rarely diagnosed through biopsy because removing tissue samples from inside the eye carries significant risks to vision. Instead, experienced ocular oncologists can typically make accurate diagnoses based on the tumor's appearance and imaging characteristics. If the cancer has potentially spread, doctors may order liver imaging studies, blood tests, and chest X-rays to check for metastases.
Complications
- Vision loss represents the most common complication of eye melanoma, occurring either from the tumor itself or as a side effect of treatment.
- The degree of vision impairment varies widely depending on the melanoma's location and size.
- Tumors affecting the central retina typically cause more significant vision problems than those in peripheral areas.
- Radiation therapy can also damage surrounding healthy tissue, potentially leading to cataracts, glaucoma, or retinal changes that affect sight.
- Metastasis, or cancer spread to other organs, poses the most serious long-term risk.
- Eye melanoma most commonly spreads to the liver, where it can be life-threatening.
- Regular monitoring with blood tests and imaging studies helps detect metastases early when treatment options may be more effective.
- The risk of spread correlates with tumor size and certain genetic characteristics that doctors can now test for in many cases.
- Newer targeted therapies show promise for treating metastatic disease, offering hope for patients who develop cancer spread.
Prevention
- Unlike skin melanoma, eye melanoma cannot be prevented through sun protection measures because ultraviolet light exposure doesn't appear to cause this cancer.
- The lack of known environmental triggers makes specific prevention strategies challenging to recommend.
- However, protecting your eyes from excessive UV radiation with quality sunglasses remains good practice for overall eye health, even though it won't necessarily prevent melanoma.
- Regular comprehensive eye exams represent the most effective way to detect eye melanoma early when treatment options are most successful.
- Adults should have dilated eye examinations every one to two years, especially after age 50 when eye melanoma risk increases.
- People with light-colored eyes or fair skin may benefit from more frequent screenings, as these characteristics are associated with higher risk.
- Maintaining awareness of vision changes and seeking prompt medical attention for new symptoms can lead to earlier diagnosis.
- Anyone experiencing persistent vision problems, new floaters, flashing lights, or dark spots in their visual field should schedule an eye examination promptly rather than assuming these symptoms will resolve on their own.
Treatment for eye melanoma depends primarily on the tumor's size, location, and whether it has spread beyond the eye.
Treatment for eye melanoma depends primarily on the tumor's size, location, and whether it has spread beyond the eye. Small melanomas that aren't affecting vision may be monitored closely with regular imaging studies, as some remain stable for years without growing or causing problems. This watchful waiting approach allows patients to maintain their vision while ensuring prompt treatment if the cancer begins to progress.
Radiation therapy has become the most common treatment for medium-sized eye melanomas.
Radiation therapy has become the most common treatment for medium-sized eye melanomas. Plaque radiotherapy involves surgically placing a small radioactive disc against the eye wall near the tumor for several days, delivering concentrated radiation directly to the cancer while minimizing exposure to healthy tissue. External beam radiation therapy directs high-energy rays from outside the body toward the tumor. Both techniques can effectively control the cancer while preserving the eye, though some vision loss may occur.
Surgical options range from removing part of the eye to complete eye removal, depending on the tumor's characteristics.
Surgical options range from removing part of the eye to complete eye removal, depending on the tumor's characteristics. Local resection removes the tumor and surrounding tissue while keeping the eye intact, though this delicate procedure is only possible for certain tumor locations. Enucleation, or complete eye removal, becomes necessary for large tumors that cannot be treated with radiation or when other treatments have failed. Many patients adapt well to prosthetic eyes that restore normal appearance.
Emerging treatments include proton beam therapy, which delivers extremely precise radiation with minimal damage to surrounding tissue, and targeted drug therapies for tumors with specific genetic characteristics.

Clinical trials continue investigating new approaches, including immunotherapy drugs that help the body's immune system fight cancer cells more effectively.
Living With Malignant Melanoma of Eye
Adapting to life after eye melanoma treatment often involves learning to cope with vision changes and regular medical monitoring. Many patients find that their remaining eye compensates remarkably well for vision loss, allowing them to maintain most daily activities. Occupational therapists can teach practical strategies for tasks that become challenging with reduced vision, while support groups connect patients with others who understand their experiences.
