Anand et al. reported their observations of 71 patients with circumscribed choroidal hemangiomas. The affected patients ranged in age from 9 to 86 years when diagnosed, with a mean of 47.7 years.
Clinical features play a key role in diagnosis.
One can make a conclusion that if an orange-red mass is located entirely anterior to the equator, it is highly unlikely that this lesion would be circumscribed choroidal hemangioma. Although clinical features observed with indirect ophthalmoscopy still play a major role in diagnosing CCH, various ancillary tests are helpful in distinguishing it from other amelanotic lesions of choroid, such as amelanotic melanomas, choroidal osteomas, and choroidal metastatic lesions. Ultrasonography is considered one of the most important tools for distinguishing various choroidal lesions. However, it is very difficult to assess the internal characteristics of a lesion which is smaller than 2.5 mm. Medium to high internal reflectivities are also seen in choroidal osteomas.
