[Intraocular pressure with miniscleral contact lenses].

Unlabelled: According to literature data, some experts do not exclude the possibility that scleral lens wear could influence intraocular pressure.

Purpose: To evaluate the influence of rigid gas permeable miniscleral contact lenses on intraocular pressure (IOP), keratometry readings and corneal thickness, and to study the correlation between scleral (IOPs) and corneal (IOPc) intraocular pressure using the Icare ic100 tonometer (model TAO11, Icare Finland Oy).

Material And Methods: The study included 99 volunteers without history of ocular diseases.

[Modern options for non-surgical correction of keratoconus].

The article reviews data on the so called non-surgical methods of keratoconus (KC) correction. The combined approach to KC treatment entails three main tasks: prevention of progression, optical correction of induced refractive disorders, and structural repair. Measures taken to accomplish the first two tasks should be regarded as symptomatic treatment, while addressing the last task requires pathogenetically oriented solutions.

[Structural organization of subcortical-stem formations of the human brain during aging].

Using "Videoplan" apparatus manufactured by "Reihert" (Austria) the authors studied qualitative and quantitative cytoarchitectonic characteristics of the ventral posterolateral nucleus of the thalamus, individual reticular nuclei of the pontomesencephalic fissure, Meynert's nucleus and locus coeruleus in senile dementia (simple-type) and Alzheimer's disease in comparison with their structure in normal subjects of various age (from 30 to 90 years). Examination of 20-microns thin sections stained after Nissl has revealed both qualitative and quantitative cytoarchitectonic changes (a reduction in the area of the profile fields of neurons) which were more pronounced, along with cholinergic Meynert's nucleus, in the serotoninergic nuclei of the fissure and particularly in patients with Alzheimer's disease in whom they were far more expressed than in those with senile dementia.
