Glaucoma can be further differentiated based on the
underlying etiology, whether primary or secondary. Primary
glaucoma is associated with either an increase in aqueous
humor production by the ciliary body or a decrease in
absorption of aqueous humor by the trabecular meshwork,
located in the angle of the anterior chamber. Secondary glaucoma
refers to increased intraocular pressure caused by any
other process,whether ocular, as in this case, or extraocular [3].
Choroidal melanoma is the most common primary ocular
malignancy with an estimated incidence in the United Statesof 6 to 7 per million people. Enucleation continues to be the
mainstay of therapy, although alternate treatments are being
pursued [4]. Although rare, ocular melanoma is an important
cause of secondary acute angle-closure glaucoma [5].
