Occasionally, these cells can increase in number and form a benign choroidal naevus. Visual impairment occurs as a result of the damage to the retina overlying the lesion. Choroidal melanomas are characterized by rapid enlargement. Choroidal malignant melanoma (CMM) is the most common primary malignant intraocular tumor in adults.

Most choroidal nevi are approximately the same size as the optic disk (optic nerve head that enters the eye) and typically exhibit a rounded or oval shape. When possible, nevi should be measured and their size documented with photography and ultrasound. A Choroidal melanoma is malignant and can be be treated successfully, most effectively when the a tumor is found small and early in the disease process. Choroidal melanoma generally manifests with symptoms of persistent photopsia (flashes), floaters, visual field loss, or visual acuity loss or it can be asymptomatic.

There are other, more serious causes of floaters, including infection, inflammation (uveitis), hemorrhaging, retinal tears, and injury to the eye. That said, if a melanoma is located near the lens, it could push the natural lens and cause irregular astigmatism. Giant nevus (basal dimension ≥10 mm) carries greater risk for malignant transformation. If the choroidal nevus has orange pigmentation, if the nevus is leaking fluid, or has a thickness of 2 mm or more, it may be (or become) a malignant choroidal melanoma. d. Gardners syndrome.
