Iris melanoma
It is an iris neoplasma of restricted malignancy. It usually appears without symptoms as a dark-coloured stain with enriched aggiosis, that spreads in the iris surface. It can cause bleeding in the anterior chamber and increase of the intraocular pressure. The expansion through the ciliary body burdens the prognosis.
Choroidal and ciliary body melanomas
Choroidal melanoma is the most common intraocular malignant tumor in adults.
Along with the ciliary body melanoma (in the posterior side of the iris) it is the most malignant with the worst prognosis comparing to iris melanoma.
They progress in a large number of cases without symptoms or they can cause vision blurring, floaters or lightning-like shapes in vision. They cause pain and they cause secondary glaucoma.
They are usually accompanied by secondary non-rhegmatogenous detachment.
The ciliary melanoma can push the iris or push the perimeter of the crystalloid lens.
