ABSTRACT
The authors analyze the results of examinations of 50 patients (70 eyes) with complicated high myopia, corrected by contact lenses. The mean visual acuity of patients in spectacles has been 0.21, in contact lenses 0.45. Hemorrhages in the fundus oculi have been detected in all the patients, these hemorrhages being a complication of myopia. Basing on the clinical and fluorescent angiography data, the authors have distinguished 2 types of myopic hemorrhages, differing in the origin, course, and outcome. Recommendations on the treatment, strategy and optic correction for patients with high myopia complicated with hemorrhages in the fundus oculi are given.

The authors have examined the thickness of the cornea in 270 patients with weak and moderate myopia during adaptation of the eye to soft or rigid contact lenses. They have revealed a linear correlation between the period of wearing the lens and the degree of the pachometric index change during adaptation of the eye to contact lenses. The maximum permissible period for daily wearing of contact lenses have been determined, not involving essential shifts in water-salt metabolism of the cornea. Optimal schedules for managing the adaptation process with rigid and soft contact lenses have been developed, based on the regularities of the corneal thickness changes related to the length of the lens wearing.

Pharmacokinetics of gentamicin administered into the eye by means of instillation or hydrophilic contact lenses was studied comparatively. The results of the study showed that gentamicin levels in the humor of the eye anterior chamber after the antibiotic administration with soft contact lenses were higher at all periods than those after instillation. Higher retention time of gentamicin therapeutic doses in the humor of the eye anterior chamber after the antibiotic administration by means of soft contact lenses is also an advantage of this administration route.
