Choroidal hemangioma is a rare congenital ocular tumor that can present as either circumscribed or diffuse. Circumscribed choroidal hemangioma (CCH) typically manifests as a red-orange mass within the posterior pole and appears similar to other ocular conditions, such as choroidal melanoma and choroidal metastasis. Proper diagnosis is crucial and is aided by the use of ancillary testing. CCH it...

Photodynamic therapy (PDT) has been used for treatment of various intraocular tumors including choroidal hemangioma, vasoproliferative tumor, amelanotic choroidal melanoma and choroidal neovascular membrane due to choroidal osteoma. This case report documents the effect of PDT for a presumed acquired retinal astrocytoma. A 42-year-old female with a juxtapapillary acquired astrocytoma was treate...

Schwannomas rarely present as intraocular tumors and are often misdiagnosed as malignant melanoma. We describe a choroidal schwannoma confirmed by sclerouvectomy. A 30-year-old woman presented with a large nonpigmented intraocular mass of the choroid in the right eye and underwent surgical excision by sclerouvectomy. Histologically, the tumor was composed of a mixture of cellular solid componen...

Choroidal osteoma is a rare intraocular bony tumor that typically manifests as a yellow-white, well-demarcated mass with geographic pseudopodal margins.1-3 This benign tumor predominantly occurs in the peripapillary or papillomacular region, most often in young women.1,2 Occasionally, choroidal osteoma can simulate an amelanotic choroidal tumor such as melanoma, nevus, or metastasis.1,2 This tu...

CASE REPORT A 30-year-old man was referred to our ocular oncology service with a diagnosis of amelanotic choroidal melanoma of the left eye. The following tests were performed: ophthalmoscopy, fluorescein angiography, indocyanine green angiography, ultrasonography, magnetic resonance imaging and biopsy. DISCUSSION The diagnosis of giant nodular posterior scleritis, as suggested by ultrasonogr...

Environmental risk factors for uveal melanomas (cancer of the iris, ciliary body, and choroid) have not been identified. To search for these, we examined the correlation of age-adjusted eye cancer incidence rates, a surrogate for uveal melanoma rates, in U.S. states with group level geographic and demographic factors using multivariate linear regression. Incidence rates for eye cancer were inve...

Histological data indicate the importance of tumor vascularization as a determinant of the biological behavior and the response to radiotherapy in choroidal melanoma. Duplex ultrasound and color Doppler imaging, the combination of B-mode ultrasound and pulse-waved Doppler analysis, were used to measure quantitatively neovascular blood flow in 31 patients with choroidal melanoma. Follow-up studi...
