Seven light sources were considered as excitation sources for ocular fluorescein fluorophotometry: tungsten, xenon flash, the continuous high pressure short arc lamps of xenon, xenon zinc iodide and mercury, and argon and He-Cd lasers. Each source was evaluated on the basis of its spectral match to the fluorescein absorption spectrum and dissimilarity to the ocular blue light hazard function. Light from the argon laser was found to be most suitable while light from the mercury arc and He-Cd laser was least. Each source was also evaluated on the basis of irradiance available at the cornea when used with a Zeiss slit lamp that had been converted to an ocular fluorophotometer.
