Summary:

The purpose of the study is to develop and study clinical effectiveness of a hardware-software complex for objectively determining the range of eye movements in diagnosis and evaluation of treatment effectiveness of ophthalmic diseases. Material and Methods. A hardware-software complex has been developed to objectively determine the range of eye movements based on the analysis of digital images of the anterior segment of the eye. Digital images of the anterior segment of the eye are standardized by lighting parameters; they can be viewed on a tablet computer screen, archived, or sent via the Internet to a data processing server. The study of the range of movement is determined for each eye separately for 8 meridians. Results. We developed algorithms for estimating the range of eye movements in relation to diagnosis of ophthalmic diseases. The developed technique and hardware-software complex for objectively determining the range of eye movements were used in 120 patients aged 6 to 83 years. Conclusion. Automation and standardization of research process provides high diagnostic capabilities of the hardware and software complex and is recommended for use in medical and preventive scientific research.

Summary:

Purpose: development of a method for computer analysis of corneal aberrations as applied to the tasks of laser surgery of the anterior segment of the eye. Material and Methods. As a result of mathematical modeling, an algorithm has been developed that is implemented as a computer program for selecting individual parameters of laser radiation depending on the optical characteristics of the cornea. Results. For astigmatism, it has been proposed to consider the topographic zones of the optical center of the cornea, 3.5 mm in diameter, and peripheral meridional zones. Aberrations at the periphery of the cornea increase by 10 %. At 1 and 2 stages of keratoconus, the rate of aberrations rises 2–3 times. In the third stage of keratoconus, in some cases keratometry and keratotopography is technically impossible. With pterygium 2 and 3 degrees, laser surgery in the peripheral zone of the cornea is impossible. Conclusion. Improving the efciency of laser operations is provided primarily by optimizing the impact parameters on the tissues of the anterior segment of the eye. The data on the types of corneal aberrations for various diseases, which indicate the need to change the parameters of laser exposure. The developed diagnostic algorithms are implemented as a computer program and allow you to optimize the parameters of laser irradiation of eye tissue.
