Melanoma of the Choroid

Diffuse melanoma of the choroid.

An 81-year-old woman with good vision was followed up with the diagnosis of a minimally active melanoma. This tumour was eventually found to be a diffuse melanoma with extraocular extension. Diffuse melanomas of the uvea are difficult to diagnose, have frequent and early extrascleral extension, and have a poorer prognosis than most melanomas of the uveal tract.

Melanoma of the Choroid in a Dog

Intraocular tumors are rare in the dog. Of the reported neoplasms, melanomas are the most common. These tumors characteristically arise in the anterior uvea and secondarily infiltrate posteriorly into the choroid and/ or anteriorly into the corneoscleral region. Advanced tumors may extend extraocularly. In the dog, isolated choroidal melanomas are extremely uncommon; to the authors' knowledge, ...

Radiotherapy for malignant melanoma of the choroid.

Twenty-two patients with choroidal melanomas were treated conservatively using radioactive radon rings with a mean follow-up of 43 months. In 14 patients there was successful tumor regression. Eight eyes were enucleated because of inadequate tumor response. Of the patients whose tumors were apparently destroyed, two have subsequently died of metastases and one eye was enucleated due to scleral ...

Echogram in melanoma of the choroid.

DiAGNOSIS is often difficult in melanoma of the choroid. This is evidenced e.g. by frequent misdiagnosings which come to light only after the enucleation of the bulbus (Reese, 1957) and by numerous more or less reliable methods of examination which have been applied for the determination of this tumour. Among the latest and, judging by the initial results, the most reliable methods of examinati...
