Description

As a utility model, a technical solution is claimed relating to a device, namely a device for light stimulation of the pupillary reaction of the eye.

The technical result obtained by using the proposed solution is the design of a device for light stimulation of the pupillary reaction of the eye.

Previously, the authors obtained the copyright certificate for the invention “Method of chromopupillometry” number (2508898). The inventive utility model of a device for light stimulation of the pupillary reaction of the eye is a technical solution to ensure the achievement of the result of the method.

The scope of the claimed utility model of the device for light stimulation of the pupillary reaction of the eye is to medicine, in particular ophthalmology.

The pupillary reaction of the eye is provided by two muscle groups, the sphincter / constriction function / and the dilator / extension /. Violations of the function of these muscles occur in many diseases of a dystrophic and inflammatory nature. A decrease in the amplitude of pupillary reactions leads to a deterioration in blood supply to the anterior segment of the eye, which, in turn, is the main cause of the development of ischemic syndrome, primary open-angle glaucoma, and cataracts. There is evidence of a relationship between the pupillary reaction and the reserve of accommodation. Controlled and dosed stimulation of the pupillary reaction is a preventive and therapeutic effect for disorders of the neuromuscular apparatus that provides the pupil reaction.

There are several devices for stimulation in ophthalmic diseases.

Laser ophthalmic stimulator device "SOKOL", Russia

LOT-01 device for laser therapy in ophthalmology, Russia

The device "SPEKL-M" for laser stimulation, Russia

PANKOV GLASSES apparatus for quantum therapy, Russia

Laser device "MACDEL 09.2" universal therapeutic, Russia

UZT-1.04O device for the treatment of various eye diseases, Russia

Maculostimulants KEM-01; KEM-ct, Ukraine

As a prototype, the apparatus of laser stimulation of the vision function VITAZOR is considered.

The device of laser stimulation of the vision function VITAZOR is used:

- Removal of visual fatigue

- Treatment of inflammatory and dystrophic diseases.

Positive effects of low-intensity laser radiation on the eyes:

- restoration of the functional activity of the retina,

- the disappearance of pain,

- enlightenment of the optical media of the eye,

- an increase in visual safety in videograms by 10% or more,

- positive dynamics in color perception,

- increased choroidal blood flow,

- reduction of destructive changes.

Operating modes: continuous or modulated radiation.

Radiation characteristics: power density - no more than 8 * 10-6 W / cm2;

wavelength - 0.65-0.67 microns.

All of the above devices are designed to affect the structure of the retina in order to improve metabolic processes and blood supply. In the modes used (continuous or short-pulse exposure, monochromatic radiation, including laser radiation), there is an effect on the pupillary reaction, but only in relation to narrowing (myosis). There is no relaxing phase of turning on the dilator and obtaining pupil dilation under these effects. Thus, they cannot be considered as methods of light stimulation of the pupillary reaction of the eye and a device for their implementation.

A useful model of a device for light stimulation of the pupil reaction of the eye is designed to optimize the effect on the neuromuscular structures of the sphincter and dilator of the iris in order to stimulate the pupil reaction of the eye. Optimization of prophylactic and therapeutic effects consists in the possibility of controlling the stimulating effect and the dynamic change of exposure parameters.

Effect: implementation of the method of chromopupillometry, increasing the effectiveness of treatment, expanding functional capabilities, the selection of individual prevention and treatment programs.

The device consists of the following structural elements.

1. obturator made of opaque elastic material, the geometric shape of which repeats the anatomical shape of the orbital part of the face. The shutter eliminates external light exposure to the retina and provides dark adaptation. The shutter is connected to the optical and lighting unit.

2. The optical unit consists of a lens with automatic focusing on the plane of the iris and a photo-recording device with the possibility of high-speed shooting of the pupil reaction / 24 frames per second and above /.

Photoregistration is performed both in the light range for recording the stage of narrowing of the pupil, and the stage of dark adaptation and maximum expansion of the pupil.

3. lighting unit. The fundamental difference between the device and its existing analogs and prototype is the presence of a lighting unit with monochromatic light sources with different wavelengths: an LED source operating in the near infrared range is used to obtain pupil images in conditions of dark adaptation, sources creating a light flux with a wavelength of 671 nm, 546 nm and 435 nm, which can be used separately, sequentially in equal or proportional combination, providing, inter alia, exposure to white light.

4. The processing unit of the received data (based on a personal computer) and providing feedback to the lighting unit.

5. Control unit for optical and lighting units.

Thus, the device allows you to obtain objective data about the pupil reaction using digital photographic registration in the conditions of dark adaptation and with a stimulating effect in the visible wavelength range. This makes it possible to evaluate the stimulating effect of a light pulse by the speed and degree of pupil narrowing. Accordingly, it is possible to widely control the light exposure in terms of duration, intensity, wavelength. New is the ability to select individual exposure parameters, that is, a dynamic character based on the initial state and during stimulation in each patient. You can also determine the effectiveness of photostimulating effects and the onset of time of hyperstimulation. There are possibilities to change any parameters of the light exposure, namely: the power of the light flux, the exposure duration, the radiation wavelength. The regulation of the parameters is carried out according to the feedback principle and depends on the parameters of the pupil reaction / degree and rate of expansion and contraction of the pupil /.

Technique for the technical use of the device for light stimulation of the pupil reaction.

The device is fixed on the orbital part of the face. Under the control of the photo-recording part of the device in the infrared range, the time of stable maximum pupil expansion is determined, then the light exposure is carried out with different wavelengths or white and the most pronounced effect of the pupil reaction is determined. Assess the rate of pupil reaction as a time function of the change in pupil diameter. The interval of light exposure is determined by the time of expansion of the pupil in conditions of dark adaptation. The possibility of chromopupillometry is realized for the first time. When you mix the three primary colors, you get a feeling of white. The duration of exposure is determined by the change in the speed and amplitude of the pupil reaction.

Thus, unlike the prototype, the utility model of the device for light stimulation of the pupillary reaction of the eye allows you to implement several new qualities:

- quantitative assessment of the pupil reaction to light exposure,

- to assess the pupil reaction according to objective data of digital images,

- make a comparative analysis of the data for the selection of individual parameters of light exposure,

- determine the stage of hyperstimulation by light exposure,

- change the parameters of light exposure (intensity, wavelength, combination of factors),

- implementation of the principle of "feedback", which allows to optimize the stimulating effect of light stimulation of the pupil reaction.

Thus, this device is new and industrially feasible.

Example 1. Patient I. 42 years. the diagnosis is open-angle subcompensated glaucoma in both eyes. The duration of the disease is 3 years. The level of intraocular pressure is 22-24 mm. Hg There is a restriction of the pupil reaction, the diameter of the pupil is 2.5-2.8 mm. There are exfoliative deposits along the pupil edge. A treatment course of 10 sessions was carried out using an apparatus for light stimulation of the pupil reaction of the eye (light flux with a wavelength of 671 nm, 546 nm and 435 nm, sequentially for 5 minutes). After the course of treatment, the amplitude of the pupil reaction increased to 4.0 mm. A decrease in intraocular pressure to 21 mm was noted. Hg

Example 2. Patient B. 25 years. Diagnosis: spasm of accommodation, weak myopia. There is excessive visual load associated with prolonged work at the computer. Objectively - there is a decrease in visual acuity without correction to 0.5. Refractometry - 0.75. Dptr. The diameter of the pupil is 2.5 mm, the reaction of the pupil is reduced. Conducted A treatment course of 10 sessions was carried out using an apparatus for light stimulation of the pupil reaction of the eye (light flux with a wavelength of 671 nm, 546 nm and 435 nm, sequentially for 5 minutes). The patient noted an improvement in vision to 0.8. Refractometry - 0.25 diopters.
