An opticnerve melanocytoma is a tumor made up of melanocyte s and melanin . These tumors are typically a benign tumor benign they can grow, but rarely transform into a Cancer malignancy . Even so, local growth can affect adjacent Tissue biology tissues . Symptoms Opticnerve melanocytoma does not usually produce symptoms or grow. If they slowly grow, opticnerve melanocytoma can produce afferent pupillary defects 30 , subretinal fluid 10 , and an enlarged blind spot 75 . For example, if the tumor is next to the opticnerve , growth can compress the nerve and cause loss of Visual perception vision e.g. nerve fiber layer defects . Growth can also cause compressive Blood vessel vascular problems like central retinal vein occlusion. Lastly, growth also causes the tumor to exceed its blood supply. In these cases, Necrosis necrotic areas form inside the tumor. Necrosis can in turn cause intraocular and rarely orbital inflammation . Diagnosis Most opticnerve melanocytomas are small, black, and do not grow. Eye tumors Category Ocular neoplasia ... more details
