Indocyanine green angiography in the diagnosis of small choroidal tumours.
OBJECTIVE
To evaluate indocyanine green (ICG) angiography in the diagnosis of small choroidal tumours.


METHODS
We studied 40 patients with small choroidal tumours, 22 males and 18 females. The tumour thickness on ultrasonography ranged from 2.2 to 4.3 mm.


RESULTS
Nineteen pigmented tumours showed early and late diffuse hypofluorescence, consistent with naevi. Eight non-pigmented tumours showed normal choroidal vessels in calibre, configuration, and branching, typical of non-pigmented naevi. The early frame of ICG angiography showed in 13 cases pathological, intrinsic vascularization, suggestive of melanomas.


CONCLUSIONS
This preliminary study suggests that ICG angiography may be helpful in differentiating choroidal naevi from small melanomas.
