[Significance of infrared angiography in the differential diagnosis of choroid tumors].
With infrared light and a dye (Indocyanin green) bound to proteins it is possible to study the choroidal circulation much better than with usual fluorescein angiography. For the differential diagnosis of choroidal tumors, this method contributes the following: (1) The diagnosis of choroidal hemangioma can be made with confidence. (2) while it is not yet possible to differentiate between a nevus and a melanoma, choroidal angiography nevertheless represents a second vascular parameter (in addition to the retina) for monitoring the growth of potentially malignant tumors. (3) The value of this method for the diagnosis of choroidal metastases and rare choroidal tumors - such as the case of an osteoma presented here - has yet to be studied.
