Is Iris Melanosis fatal?
Iris melanosis is benign, but it can transform into malignant cancer. Close monitoring by an ophthalmologist is recommended to catch early changes in the disease that could potentially be fatal for the eye. It is common to first notice pigment as a small, flat, and benign nevus, or “freckle” on the iris.
How is Iris Melanosis treated?
Treatment for Iris Melanosis Some ophthalmologists recommend laser therapy – targeted destruction of the iris melanosis – in early stages of the condition. The goal of this therapy is to prevent or delay the transformation of iris melanosis to malignant melanoma.
How long do cats live with melanoma?

What is the survival rate for ocular melanoma?
The 5-year survival rate for eye melanoma is 82%. When melanoma does not spread outside the eye, the 5-year relative survival rate is about 85%. The 5-year survival rate for those with disease that has spread to surrounding tissues or organs and/or the regional lymph nodes is 71%.

What causes ocular melanosis?
The disease is caused by an increase of melanocytes in the iris, choroid, and surrounding structures. Overproduction of pigment by these cells can block the trabecular meshwork through which fluid drains from the eye. The increased fluid in the eye leads to increased pressure, which can lead to glaucoma.
What do brown spots in cat’s eyes mean?
Iris melanosis is darkening of the iris of cats that occurs from proliferation of cells that produce a brown pigment called mela- nin. Iris melanosis may begin as a focal, dark spot or as several spots. A single spot of flat, irregular pigmentation may be called a freckle.
