Eye Cancer Types: Key Facts
Ocular Melanoma
Eye Cancer Types: Key Facts Ocular melanoma is a type of eye cancer that develops in the melanocytes, the cells that produce pigment in the eye. This form of cancer primarily affects adults, with a higher incidence in individuals over 50 years old. Ocular melanoma can occur in various parts of the eye, including the iris, ciliary body, and choroid.
Symptoms:
- Blurry vision
- A dark spot on the iris
- Floaters or flashes of light
- Loss of vision in the affected eye
- Pain or pressure in the eye
Diagnostic procedures:
The diagnosis of ocular melanoma involves a comprehensive eye examination, including visual acuity tests, dilated eye exams, and imaging tests like ultrasound, optical coherence tomography (OCT), and fluorescein angiography.
Treatment options:
The treatment for ocular melanoma depends on the size, location, and stage of the tumor, as well as the overall health of the patient. Treatment options may include:
- Observation: For smaller tumors that are not growing or causing symptoms, regular monitoring may be recommended.
- Radiation therapy: This treatment uses high-energy rays to kill cancer cells. Techniques like plaque brachytherapy or proton beam therapy may be used.
