[Retinal function under conditions of artificial illumination with varying spectral makeup in patients with sclerotic macular dystrophy].
In conditions of a laboratory experiment using illumination of various light sources (by incandescent, luminescent, arc-mercury, natrium lamps), determination of visual acuity, visual field, color perception, restoration time of visual acuity after macular flash lighting (photostress test), Heidinger's phenomenon as well as visocontrastometry after V. V. Volkov, Weston's correction test were conducted in 46 patients (92 eyes) with macular dystrophy and 50 healthy persons in the dynamics of a working day. It was found that the spectral composition of the visible light has a remarkable influence on the function of color perception, contrast sensitivity, reaction of visual analyser on light load, visual ability to work. In patients with macular dystrophy, the dependence on the light medium was expressed much greater than in healthy persons. The highest functional state of the retina and visual ability to work in patients with macular dystrophy were provided by natrium lamps having a maximum radiation in the yellow part of the spectrum. The short-wave visible light of arc-mercury and luminescent lamps somewhat suppressed the functional state of the retina and reduced visual ability to work. The results obtained are important for selection of optimal conditions of work for patients with macular dystrophy.
