Two differing presentations, treatments, and outcomes of malignant choroidal melanoma

Choroidal melanomas represent the most common primary malignancy of the eye. As primary eye care providers, optometrists must be able to identify suspicious lesions to facilitate proper referrals and timely treatment. Metastasis occurs in approximately 75% of cases. Ongoing studies such as the Collaborative Ocular Melanoma Study are bringing new information on how to best manage choroidal melanoma. Current treatments include enucleation, plaque brachytherapy, and transpupillary thermotherapy.

Two patients presented to the Veterans Affairs (VA) Illiana Health Care System optometry clinic for routine visits and had malignant melanomas diagnosed. The first patient was in for a 6-month routine glaucoma follow-up, noting that the right eye seemed to be worse. The second patient was new, complaining of a painful, red eye. Both were referred to a retinal specialist and later treated by an ocular oncologist with enucleation and plaque brachytherapy, respectively. Their differing chief complaints and cases are discussed.

Patients with malignant choroidal melanomas present with a wide variety of complaints, and optometrists need to be diligent in properly assessing the cause of seemingly common conditions, such as anterior uveitis, as well as performing routine dilated fundus examinations. Given the relationship between size and prognosis, early detection is important.
