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.

Choroidal hemangioma, a benign vascular tumor of the choroid, can frequently develop an effusive secondary retinal detachment. When such retinal detachment involves the macula, reduction in central vision occurs. Fluorescein angiography and radioactive prosphorus tests are helpful in accurately diagnosing choroidal hemangioma. Transscleral cryopexy, freeze-thaw-refreeze method, results in complete destruction and scarring of the choroidal hemangioma. Following treatment, subretinal fluid disappears, the macula becomes reattached, and central vision is restored.

We compared 19 choroidal hemangiomas and 21 choroidal melanomas of comparable size as to the percent of radioactive phosphorus 32P uptake. The results were significantly lower in choroidal hemangiomas than in comparable sized melanomas.

An amelanotic fundus lesion in a 35-year-old man was associated with a dilated retinal vessel, thus suggesting the diagnosis of retinal angioma. Fluorescein angiography and B-scan ultrasonography were not diagnostic, but a radioactive phosphorus uptake test suggested the lesion was malignant. The enucleated globe showed a malignant choroidal melanoma drained by a large retinal vein.

Results from a 32P test in a histologically proven choroidal hemangioma were normal in a case we recently evaluated. It is believed that this case is important because of the infrequent number of confirmations with this test.
