Symptoms of uveal malignant melanoma with a positive isotope 32 phosphorus uptake test. Uveal malignant melanoma is the most common type of malignant intraocular tumor in adults, and its incidence accounts for the first place of intraocular tumors in foreign countries, and the second place of intraocular tumors after retinoblastoma in China. This tumor has a high degree of malignancy, easily metastasized through blood flow, and is relatively common in adults, and is easily confused with many fundus diseases in clinical work. Therefore, it should be fully emphasized in ophthalmology clinical work. This disease is more common in patients above middle age. The posterior pole of the eye is the most common site, and the incidence decreases from the front. How to effectively prevent uveal malignant melanoma? Prevention Malignant melanoma of the uvea (maligmentmelanomaofuveal) is a kind of malignant intraocular tumor most common in adults, and its incidence accounts for the first place of intraocular tumors in foreign countries, and second only to retinoblastoma in China, which is the second place of intraocular tumors. This tumor has a high degree of malignancy, easily metastasized through blood flow, and is relatively common in adults, and is easily confused with many fundus diseases in clinical work. Therefore, it should be fully emphasized in ophthalmology clinical work. This disease is more common in patients above middle age. The posterior pole of the eye is the most common site, and the incidence decreases from the front. Malignant melanoma of the uvea can develop inwardly or outwardly. Outward progression causes extraocular spread in the early stage, and the eyeball may protrude clinically with little change in the fundus. Inward progression causes a spherical bulge under the retina, which develops rapidly and has a short course, with early visual impairment and extensive retinal detachment, and is the more common clinical type. There is also a rarer type that develops along the choroidal plane, forming diffuse, flattened proliferation without forming a limited bulge. The prognosis for malignant melanoma of the choroid is better than that of the cutaneous type, with a mortality rate of 50% in the former and up to 80% in the latter. Local recurrence or metastasis mostly occurs within 1 year after surgery, and can extend for 5 or 10 years or more in individual cases that survive long enough. There is a close relationship between prognosis and tumor cell type, with spindle cell type having a lower mortality rate and epithelial cell type having a higher mortality rate. Surgery (1) If the tumor is located in the eyeball, ophthalmectomy should be performed. General anesthesia and local anesthesia should be avoided to prevent the spread of tumor cells. (2) If the tumor spreads outside the eyeball, orbital content removal should be performed. (2) If the tumor spreads outside the eyeball, orbital content removal should be performed. Encourage patients to establish confidence in overcoming the disease, mobilize patients’ subjective enthusiasm, maintain optimism and avoid tension. Pay attention to maintain sufficient sleep, avoid overwork, pay attention to the combination of work and rest, and pay attention to the regularity of life. Reasonable diet, diet should be light, avoid spicy stimulating food.
