(54) СПОСОБ ЛЕЧЕНИЯ ГЕМОФТАЛЬМА(54) METHOD OF TREATMENT OF HEMOFTALM

Изобретение относитс к области медицины , а именно офтальмологии.This invention relates to the field of medicine, namely ophthalmology.

Известен способ лечени гемофтальма путем ультразвукового облучени 1J.There is a method of treating hemophthalmus by ultrasound irradiation 1J.

Однако лечение таким способом вл етс длительным и недостаточно эффективным .However, treatment with this method is long and not sufficiently effective.

Целью изобретени вл етс сокращение сроков лечени .The aim of the invention is to reduce the duration of treatment.

Это достигаетс тем, что облучение производ т одновременно двум лучами, один из лучей генерируют с частотой колебани в диапазоне 800-1500 кГц и частотой качани до 50 Гц с пересечением лучей в заднем отделе глаза при общей интенсивности облучени в зоне пересе15ени 0,2 - 0,4 Вт/скСThis is achieved by the fact that irradiation is carried out simultaneously by two beams, one of the beams is generated with an oscillation frequency in the range of 800-1500 kHz and a sweep frequency of up to 50 Hz with the rays intersecting in the posterior part of the eye with a total irradiation intensity in the intersection zone of 0.2-0. , 4 W / SC

На чертеже схематически показано введение ультразвука в задний полюс глааа двум лучами, мину хрусталик.The drawing shows schematically the introduction of ultrasound into the posterior pole of the eye with two rays, the lens of the lens.

После предварительной анастезии глаза дикаином на глазное блоко больного устайавливают ванночку-векорасширитель 1, выполненную, например, из органического стекла, в которой выходное отверстие закрыто эластичной прокладкой 2 из акустически прозрачного материала, например, из тонкой полиэтиленшой пленки . На ванночке-векорасширителе подAfter preliminary anesthesia of the eye with Dicain, the patient’s ophthalmic block is placed on the bath-speculum 1 made, for example, from organic glass, in which the outlet is closed by an elastic gasket 2 of an acoustically transparent material, for example, from a thin polyethylene film. In the bath-speculum under

углом по обе стороны хрусталика облучаемого глаза смонтированы два отдельных 3 и 4 ультразвукового импульсатора , питающиес от источников ультразвука 5 и 6 соответственно.The angle on both sides of the lens of the irradiated eye is mounted two separate 3 and 4 ultrasonic pulsers fed by ultrasound sources 5 and 6, respectively.

В качестве источников примен ютThe sources used

Claims

800 kHz ultrasound therapy devices, for example, UTP-1. The spacer 1 is filled with distilled water, which serves as an acoustic medium for transmitting ultrasonic energy, since its specific wave impedance is close to the specific wave impedance of the psyche of the eye. The acoustic axes of the ultrasonic rays from the individual elements 3 and 4 of the ultrasonic pulser, while simultaneously affecting the eyes with two rays aa and bb, a crystalline lens (see drawing), converge at an angle at the posterior pole of the eye and intersect each other. Intensity of ultrasonic rays folding; . To mitigate interference in the intersection of sound fields from individual elements of the ultrasonic pulse gun, one of them, for example, element 3, operates from source 5, which contains a sweep frequency generator. The therapeutic device generator TP-1 has been upgraded to obtain an oscillating frequency in the range of 800–1500 kHz with a sweep frequency of 50 Hz. After installing the bath-eyelid 1 on the eye block of the patient include sources 5 and 6 of ultrasound. Ultrasonic irradiation is carried out both in continuous, and in the simultaneous combination of continuous and pulsed radiation modes with a total intensity of both ultrasonic rays in the range of 0.2-0.4 W / cm in the intersection area of ultrasonic rays aa and bb is selected and set by the intensity of each of the rays individually. In the treatment of a combination of continuous and pulsed radiation modes, the intensity of a pulsed ultrasound beam is doubled, for example, 0.1 + 0.1 0.2 Vg / cm I 0.15 + 0.15 0, ZW / cm 0.2 + 0.2 - 0.4 W / em, and in combination of continuous and pulsed radiation modes, 0.1 + (0.1 + 0.1) 0.3 W / cm; 0.2 + (0.2 + O, 2) 0.6 W / cm, etc. Irradiation sessions are performed 8–10 days once a day, the exposure time is 8–10 minutes. The proposed method for the treatment of hemophthalmus allows ultrasound irradiation of the posterior pole of the eye at the same time by two beams, bypassing the talik without significant loss, thereby more effectively affecting the pathological formations in the central zone of the eye, which significantly reduces the treatment time. The invention The method of treating hemophthalmus by ultrasound irradiation, which means that, in order to shorten the duration of treatment, irradiation is performed simultaneously by two beams, one of the beams is generated with a frequency of 800-1500 kHz and a frequency shifts up to 50 Hz with the intersection of rays in the posterior part of the eye with a total irradiation intensity in the intersection zone of 0.2 - 0.4 W / cm.
