Abstract
Fluorimetry of an eye is a perspective technique for research and diagnostics in Ophthalmology. It is connected to the structural and functional characteristics of eye that is, actually, the optical system allowing transferring the radiation both for excitation and for registration of fluorescence in different eye’s compartments: cornea, lens, vitreous body, and fundus of the eye. At present, different models of ophthalmologic fluorophotometers for the analysis of eye fluorescence as well as more advanced models – scanning fluorophotometers - are offered. Assessment of corneal status in persons wearing contact lenses or in patients with pathological changes (i.e. diabetes mellitus) would give us an opportunity to identify the initial manifestations of corneal pathology in the presymptomatic phase. The goal of this study was to develop the method of anterior eye camera assessment with UV-induced fluorescent spectroscopy in persons wearing contact lenses. As a result, we have developed spectrofluorimetric method for the diagnostics of limb areas in the human eye. Spectral criterion for characterizing the state of the limb area as the ratio of the fluorescence intensity on the wave lengths of 465 nm and 503 nm, respectively, is proposed. Our method is sensitive enough to register pathological changes in the absence of clinical manifestations (presymptomatic phase).
