Introduction. One of the reasons for the unfavorable outcome of glaucoma is an incorrect evaluation of the eye hydrodynamics data obtained by measuring intraocular pressure. That is why the development of new non-invasive methods of intraocular pressure studying is an urgent task. The cornea is optically anisotropic due to the effects of direct extraocular muscles and intraocular pressure on it, as well as the structure and properties of corneal collagen. When an eye cornea is illuminated by polarized light, we can observe an interference pattern which reflects the distribution of internal stresses in it. The parameters of interference patterns depend on the level of intraocular pressure.
The purpose of the article is to develop the telemedicine system’s conception for express estimation of intraocular pressure level with the use of interference pictures that are observed on glaucoma patients’ cornea in polarized light.
Results. The method for determining the interference parameters is performed in several stages in accordance with the developed algorithm. First, after receiving a color picture of interference pattern, its brightness is normalized and converted to monochrome. At the second stage, the cornea borders are fixed by means of two mode indicators, after which the contour is automatically applied to the image. At the third stage, the isochromatic contour is labeled using an adjustable ring pointer, which allows defining the isochrome width middle and standardizing the studies. After marking out the contour of the isochrome using splines, the isochrome itself is modeled. At the fourth stage, there is an automated calculation of the pixels forming the isochrome and filling the inner part.
Conclusions. To assess the level of intraocular pressure using interference patterns, it is necessary to determine their parameters, which can be performed in a semi-automated mode. The developed method provides a resolving power of at least 0.55 mm/pixel (3 times better than the known one) and reduces the research time by 11–15 times. It is not labor-intensive and can be implemented in the central regional hospital.

Keywords: telemedical system, polarized light, interference patterns, isochromes, parametrization.

Introduction. PC operators’ work is connected to necessity of information large amounts perception from PC display. Such activities require of high attention concentration and particular responsibility for production goals. Arduous visual work of PC operators on close distance results in high psychoemotional stress and exerts an impact on functional state. Severe visual asthenopias in PC operators may be observed on the background of normal values of visual system’s functional indexes that require of such states causes determination for prophylaxis measures development.

The purpose of the article is to evaluate the impact of the visual work at close distance on the structure of relationships between visual system’s indexes and functional state’s indexes.

Methods. 41 PC operators took part in the study. The average age of study subjects was (29,6 ± 4,0) y.o. The functional indexes of visual system were measured in all PC operators before and after visual work. The indexes of functional state were also measured by self-assessment using developed questionnaire. The obtained results processing was performed using descriptive statistics methods, cluster and factor analysis.

Results. On the background of performed research using clustering and factor analysis it was found that younger PC operators with higher visual functions the visual work on close distance results in state similar to spasm of accommodation. The recovery after night rest was worse than in PC operators with low visual functions. Older PC operators have higher quality of recovery after night rest. It may be determined by development of visual fatigue as the result of visual work . The recovery after night rest in case of visual fatigue is better than in case of accommodation spasm.

Conclusion. Visual work on close distance results in configuration change of connection between indexes of visual system that support visual perception. The peculiarities of these changes depend on visual system’s indexes. The results of PC operators functional state’s self-assessment using the questionnaire developed by us had shown that in PC operators with low functional possibilities the common and visual complaints rate was certainly lower than in operators with high functional possibilities.

Keywords: factor models, visual system, functional state, PC operator work.
