Arch Ophthalmol. 1970;83(6):700-703. doi:10.1001/archopht.1970.00990030700005
Abstract

The use of Ektachrome infrared aero film is recommended in fundus photography to reveal melanin, especially to differentiate choroidal melanomata from metastases and other lesions containing no extra melanin. Melanin shows up dark brown while blood shows up yellow, provided the correct exposure is used.
