Description

The invention relates to medicine, namely to methods for treating eye diseases, and can be used to treat accommodation spasm.

Accommodation - the ability of the eye to change its gaze - to look into the distance and at close range. Due to the contraction of the ciliary muscle, on which the lens of the eye is suspended, the image of the object is focused on the retina of the eye. Long-term visual load close to the eye is not physiological. When working on a computer with an visual load of more than 4 hours a day, a spasm of the ciliary muscle occurs. Given global computerization, the treatment of accommodation spasm is very important nowadays.

Traditional treatments use:

1. Vision correction with glasses and contact lenses. This not only strengthens, but also exacerbates the spasm of accommodation. The ciliary muscle is more spasmodic, the phenomena of asthenopia and degenerative changes are amplified.

2. Cycloplegia - instillation of mydriatic preparations into the eyes (tropicamide, mydriacyl, irifrin, cyclomed).

With cycloplegia, partial cramping and relaxation of the ciliary muscle occurs. The duration of drug instillation is from 14 to 30 days, depending on the degree of spasm.

The disadvantages of this method:

- the inability to use in working people;

- decreased visual acuity and increased photophobia during instillation of drops;

- complete relaxation of the ciliary muscle does not occur.

3. Operation lasik - evaporation of the cornea, resulting in a change in focus by reducing the thickness of the cornea.

The disadvantages of the method: the ciliary muscle remains spasmodic, gives a temporary result; with visual load on nearby objects, myopia persists; complications after surgery (early - keratitis, destruction of the vitreous body, distant - increased intraocular pressure, the development of glaucoma)

4. Contact lenses

At night, hard contact lenses are put on the cornea, under the weight of which the cornea is flattened and its curvature changes.

The disadvantage of this method:

- gives a temporary effect, for a day the cornea returns to its original position;

- corneal trauma;

- does not affect the pathogenetic side of the disease;

- the absolute inefficiency of the method in the treatment of accommodation spasm.

A known method of treating eye diseases (dysbinocular amblyopia) [1], based on exposure to argon laser radiation operating in a pulsed mode.

However, the known method does not allow to get rid of the spasm of accommodation. The closest technical solution to the proposed invention is a method for the treatment and prevention of the progression of myopia in children [2], which includes the combined exposure to pulsed laser infrared (IR) radiation with λ = 890 nm and a pulsed power of 8-20 W, pulsed incoherent infrared radiation with λ = 860-960 nm with an average power of 60 ± 30 mW, pulsed red radiation with λ = 600-700 nm with a frequency of 2 Hz and a constant magnetic field with magnetic induction of 35 ± 10 mT on the occipital-parietal region of the head, neck, carotid sinuses and bio logically active points (BAP), while the occipital-parietal region of the scalp from the coronary suture of the parietal bone to the hole along the midline of the aponeurosis is affected by laser IR radiation with a pulse power of 20 W, with a frequency of pulsed laser and incoherent IR radiation of 1000 Hz with a scanning movement from top to bottom with a duration of exposure of 2-4 minutes, then they act at the lower edge of the occipital bone between the tendons of the biting and trapezius muscles on both sides of the infrared laser radiation of pulsed power new 8 W, a frequency of pulsed laser and incoherent IR radiation of 50 Hz with an exposure of 2 min per field, then they act on the carotid sinuses on both sides with a pulsed power of laser PC radiation of 8 W, with a frequency of pulsed laser and incoherent IR radiation 50 Hz exposure time of 2 minutes, then the symmetric BAT is affected by the power of the laser IR radiation of 8 W with a frequency of pulsed laser and incoherent IR radiation of 1000 Hz initially on the points of general action: F ₂ , F ₃ , F ₃₆ , Gi ₄ , IG ₃ , TR ₁₀ , V ₆₂ , then with pulse power laser infrared radiation of 8 W, with a frequency of pulsed laser and incoherent IR radiation of 5 Hz to local action points around the eyes: E ₁ , E ₂ , TR ₂₃ , VB ₁ , V ₁ , V ₂ , BT ₆ and auricular points: AT ₈ , AT _24a , AT ₂₄ , with an exposure of 20-30 s for each point with a duration of exposure of 6-9 minutes, the course of treatment is 8-12 sessions.

The known method provides multifactorial (combined), simultaneous exposure to various types of radiation: pulsed infrared laser radiation, pulsed broadband infrared radiation, pulsating red radiation, as well as a constant magnetic field.

However, the use of only pulsed types of radiation does not fully ensure the high treatment efficiency and achieve the stability and durability of the treatment result in the treatment of accommodation spasm for each specific case due to the non-use of the possibility of combined exposure to continuous radiation and additional drugs.

The problem to which the invention is directed, is to increase the effectiveness of the treatment of accommodation spasm.

The technical result, which consists in increasing the stability and durability of the treatment result, is achieved in the proposed method for the treatment of accommodation spasm, including the impact on the infraorbital region and adjacent areas of the region with pulsed radiation and a magnetic field, in that they have a combined effect of pulsed radiation with a wavelength of 800-1200 nm and continuous radiation with a wavelength of 630-670 nm, while the effect is carried out by pulsed radiation with an average power P _cf.imp = 3.0-10.0 mW, pulsed power P _imp = 2.0-4.0 W and with a pulse repetition rate f _imp = 5.0 Hz-10.0 kHz, exposure to continuous radiation is carried out with an average power of P _av.nepr up to 50.0 mW, and exposure to a magnetic field is carried out when the magnetic field strength H is in the range H = 20-45 mT, moreover, the aforementioned joint action is carried out alternately or simultaneously in the zones of the superciliary arches, in the temporal and infraorbital region, the exposure time T _air in these zones is maintained in the range T _air = 1.0- 5.0 min, while before each session the patient is instilled roficheskih drops, and in one course of treatment is carried from 7 to 15 treatments.

In this case, a repeat of the course of treatment is carried out after 1.0-2.5 months. The proposed method is as follows.

For the hardware impact, a quantum therapy apparatus such as the Rikta apparatus with advanced functionality was used (an analog of the device [3]). Before each session, the patient occupies a horizontal position and he is instilled with trophic drops.

Then, radiation excitation elements connected to the device are applied to the infraorbital region and adjacent areas (in the areas of the superciliary arches and in the temporal region) and the necessary mode of operation is set using the controls. The radiation excitation elements are arranged alternately or simultaneously.

When the device is turned on, a combined combined effect is exerted on the infraorbital region and adjacent areas by electromagnetic radiation, magnetic field and drugs. In this case, they are simultaneously affected by pulsed radiation with a wavelength of 800-1200 nm and continuous radiation with a wavelength of 630-670 nm.

Pulsed radiation is generated with an average power P _cf.imp = 3.0-10.0 MW, a pulsed power P _imp = 2.0-4.0 W and a pulse repetition rate f _imp = 5.0 Hz-10.0 kHz . Continuous radiation is generated with an average power of P _av.nepr up to 50.0 MW. The exposure time T _air in these zones is maintained in the range of T _air = 1.0-5.0 minutes

The magnetic field strength H is provided in the range H = 20-45 mT.

Depending on the patient’s condition, in one course of treatment, from 8 to 12 sessions are carried out. Repeating the course of treatment is carried out after 1.0-2.5 months. The device’s electromagnetic radiation acts as a “pulse therapy”, which relieves the spasm of the ciliary muscle, restoring its normal state. In this case, the instillation of trophic drops before each session (taufon, emoxipin) when exposed to electromagnetic radiation allows the drops to penetrate to the deeper layers, which enhances the effect of both the drops and electromagnetic radiation.

In well-known traditional methods of treatment, drops pass only to the middle layers of the eye, and their effect on the deeper layers does not appear.

The selected localization of the elements of the excitation of electromagnetic radiation allows the radiation of the apparatus not only to relieve the spasm of the ciliary muscle, but also significantly improve the hemodynamics of the eye, because these elements are located in the projections of the ciliary muscle and circular muscles of the eye. This removes the spasm from the ciliary muscle and removes the phenomena of asthenopia. Thus, the vicious circle that caused this disease is destroyed.

The proposed method allows to achieve high efficiency in the treatment. Impulses from the ciliary muscle enter the brain - binocular vision is also restored, and hemodynamics and trophism of the eye improve.
