However, optical coherence tomography (OCT) is a more sensitive way to detect subretinal fluid retinal detachment. Patients with such advanced melanomas are likely to have extensive distant metastases and poor prognosis for survival, with or without orbital exenteration surgery. [46,47] Results have been generally encouraging but complications of radiotherapy include radiation retinopathy, cataract, vitreous hemorrhage, and neovascular glaucoma.

After a choroidal melanoma has been diagnosed, an MRI (magnetic resonance imaging) scan may be ordered. Jensen OA. The past medical history may reveal a non-ocular malignancy, which would be suggestive of a metastatic lesion although one needs to be careful with this information because 6% to 10% of uveal melanoma patients have another primary neoplasm. It occurs most frequently at age 55 to 60. Circulation:Double circulation pattern consisting of an internal circulation within the lesion and the normal vascularity of the overlying retina. Lesions with three or more factors will show growth in more than 50 percent of cases. Differentiating between benign choroidal nevi and small malignant melanomas can be challenging.

Nodular melanoma is the most aggressive form of skin cancer. COMS Report No. Lee JA, Storer BE. Thus, early detection is important. If patients have choroidal melanoma symptoms, they are usually seeing flashes of light, noticing distortion or loss of vision, and floating objects (floaters) in their vision. Among the tests that may be ordered during the metastatic workup for a patient with choroidal melanoma are: Most uveal melanomas have no genetic predisposition. In general, the larger the choroidal melanoma the worse the prognosis for both vision and metastasis. Retina 2007;27:6817.

Systemic chemotherapy is the primary treatment in such cases. [22,23] Acute or intense exposure to ultraviolet light might increase the risk of uveal melanoma, butthe role of acute or chronic sunlight exposure remains inconclusive. Significant intraocular inflammation is also uncommon in melanoma and is more consistent with inflammatory diseases. Other Ancillary tests and procedures: High resolution computed tomography (CT) is less accurate than ultrasonography and is more expensive.[. There are two germline mutations responsible for hereditable melanoma: loss of BAP 1 expression as in BRAC1-associated protein-1 (BAP1) tumor predisposition syndrome (BAP1-TPDS)[6] and more recently, inactivation of Methyl-CpG Binding Domain 4 (MBD4).[7]. [56] included genetic testing in their analysis for factors predictive of metastatic death and found the most important independent predictors to be basal tumor diameter, chromosome 3 loss, and epithelioid cell histopathology. T1 tumors are the smallest; T4 tumors are the largest. Singh AD, Kalyani P, Topham A. Estimating the risk of malignant transformation of a choroidal nevus. The available literature suggests that risk of choroidal and ciliary body melanomas associated with nevi of the uveal tract is low. What did it show? Other conditions with an increased incidence of uveal melanoma include dysplastic nevi and Nevus of Ota (estimated that 1:400 will develop uveal melanoma). Of note, amelanotic choroidal melanomas will not resemble blood on exam or by MRI. Gunduz K, Pulido JS, Bakri SJ, et al.
