The ophthalmology radioactive phosphorus uptake test has been utilized in the differential diagnosis of intra ocular lesions in 21 patients. In the majority of the cases the diagnosis was histologically confirmed. When the lesion is located in the anterior part of the globe, it is not necessary to make an incision of the conjunctiva to perform the test. If the lesion is located in the posterior segment, the test is performed by the transscleral route, with surgical incision of the conjunctiva and with indirect ophthalmoscopy control when possible. In 3 patients with choroidal hemangioma were results false-positives, observed with inferior P32 uptake to that in patients with choroidal melanomas. One false-negative result was obtained in a patient with a clinical diagnosis of uveal malignant melanoma, histologically confirmed after enucleation of the globe. In all others patients with uveal malignant melanoma results were highly positive.

A malignant melanoma of the choroid presented with a massive vitreous hemorrhage which prevented any view of the posterior pole. The diagnosis was confirmed by the results of a radioactive phosphorus test and ultrasonography. In eyes with opaque media, these tests will ofter prevent delays in diagnosis.
