methods of ophthalmologic research
All patients passed detailed ophthalmologic inspection with application of modern diagnostic equipment.
Visual acuity without correction and with optimum correction was defined by means of projector CP-50 by firms Bon (Germany).
Selection of full correction for each eye carried out by means of a set trial ochkovyh lenses [73, 97].Dynamic refraction estimated by means of a set ochkovyh lenses on the least spherical lens or sferotsilindricheskoj the combination of lenses giving the maximum visual acuity.
Clinical (static) refraction investigated a skiascopy method mainly in first half of day in conditions tsikloplegii after instilljatsii a solution tsiklomeda 1 %. The clinical refraction was defined also with the help avtokeratorefraktometra Speedy-K by firms Nikon (Japan). Measurements were made for each eye separately.
The biomicroscopy was carried out on slit lamp SL-85 by firms Bon (Germany) by the standard technique [97, 222].
Definition of a stock of relative accommodation was carried out by E.S.Avetisova's technique [2].
Eyeground survey spent in conditions tsiikloplegii by means of direct ophthalmoscope BETA 200 Heine (Germany) [2].
Ehobiometriju carried out on the apparatus «Ultrasonic Biometer Model 820» (USA) with measurement perednezadnego the size of an eye (PZO), depths of the forward chamber, a thickness of a lens [139, 210].
Before influence and after a 10-day course of influence INEMP at 10 patients (20 eyes) with HBN and short-sightedness, assotsiirovannymi with undifferentiated DST, electrophysiological research (EFI) - registration electroretinographias (ERG) and a pattern - of the visual caused potentials (PZVP) [73, 219] has been carried out.
Electrophysiological researches carried out together with the doctor - the electrophysiologist of the Morozovsky children's city hospital, k.m.n. I.E.Hatsenko.
ERG, PZVP registered on an electrophysiological combine Er - 1000 Rgo firms "TOMEY" (Japan), corresponding to standards of the International society of a clinical electrophysiology of sight (ISCEV) [219, 240]. The ERG of 30 Hz carried out under the report “ERG Standart” with registration of the bacillary answer, maximum the ERG, the coneal answer, rhythmic the ERG on red stimulus frequency. At registration the ERG used hlorserebrjanyj chashechkovyj an electrode which fastened an adhesive plaster on a skin in area between an internal and average third of lower eyelid. Record spent monokuljarno, the pupil did not extend.
At registration the ERG was carried out the amplitude and latence analysis and - a wave reflecting function of photoceptors of a retina both their hyperpolarization, and b-waves (or transretinal potential) the basic which source of generation is the membrane of cells of Muller and reflecting bioelectric activity depending on
Conditions of adaptation, function photopic and skotopicheskoj retina systems [73, 219].
PZVP registered on the external monitor under the report “VEP Patt ext” on chess fields with the sizes of cells 60; 20; 8 ugl. Minute monokuljarno with optimum correction. A locating of electrodes: indifferent on a forehead, earthing on an ear ear lobule, active on an average line on 2 sm above an occipital hillock. At registration PZVP considered the basic waves - negative N80 (latence) and positive P100 (amplitude and a latence) [73, 219].
