[Methods of the analysis of images in the diagnosis of diseases of the anterior eye segment].
Methods of mathematical computerized analysis of images obtained through the microscopy of the eye by the slit lamp were used in examining patients with different pathologies of the eye anterior segment. Densitometric and planimetric analysis of images of the cornea, lens as well as of the posterior and anterior capsules of the lens was made for patients with aphakia and artiphakia. The optic corneal density (which depends on a type and degree of refraction and an administered medication therapy) was found to change after excimerlaser procedures. The corneal transparency, which also depends on an administered medication therapy, was examined in cases of its opacities and photokeratitis. Examinations of the lens led to elaborating a clinical classification of cataract maturity degrees, which can be used during the preoperative period for planning a type and tactics of the therapeutic and surgical treatment. Main complications occurring after cataract extraction, i.e. opacities in the anterior and posterior capsules, were evaluated densitometrically. A classification of opacities in the lens capsule was worked out; it was used to determine the optimal time and types of the therapeutic and surgical treatment at secondary cataracts.
