Abstract

The optics of slit-lamp fluorophotometry were analyzed. This analysis forms the basis of the formulation of a slit-lamp technique called photometric oculometry, which makes it possible to measure intraocular distances.

A comparison between ultrasonography and photometric oculometry in the determination of the ocular axial length was carried out. Measurements in 11 eyes showed statistical agreement, with a mean of 22.90 mm, SD ±1.815 (ultrasound), and a mean of 23.17 mm, SD ±1.667 (photometry).

The principle involved in photometric oculometry is of special importance for the calculation of the blood-retinal barrier permeability to fluorescein by vitreous fluorophotometry, since the method allows the volume of the vitreous body to be estimated directly from the slit-lamp fluorophotometer recording.
