The pooling of fluorescein on small corneal defects is best seen by means of ultraviolet or cobalt blue light for illumination. This causes the fluorescein to fluoresce. There is a danger with fluorescein in solution form. WebFluorescein is stimulated by blue light (465 to 490 nm) and emits at a green wavelength (520 to 530 nm). Fluorescein angiography requires the use of two filters, an exciter filter that transmits the blue light and a barrier filter that transmits the emitted green light.
