Description

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

In the presence of myopia, vision correction using contact lenses is widely used. Contact lenses (regardless of what material they are made of) are a foreign body on the cornea. When wearing contact lenses, the cornea is not wetted by a tear, proteins, microscopic dust particles accumulate under the contact lens, which can lead to chronic inflammation of the cornea - keratoconjunctivitis.

In this case, the corneal epithelium is reborn. Inflammatory precipitates form, due to which the cornea becomes cloudy. Corneal erosion occurs, and sometimes a thorn is a persistent, incurable decrease in vision.

Contact lens wear may cause keratoconjunctivitis.

Traditional methods of treating keratoconjunctivitis are reduced to the instillation of anti-inflammatory and trophic drops.

This does not completely eliminate this disease; a further decrease in vision may occur. Therefore, this problem is relevant.

A known method for the treatment of insufficiency of tear production in case of dry eye syndrome [1], which consists in the pharmacological stimulation of tear production, in particular the drug eledoisin.

However, this method is effective only subject to the existence of reserve capabilities of tear production. In addition, the limitation of its use is the high cost of the drug used.

There is also a method of treating dry keratoconjunctivitis with Sjögren’s syndrome [2] by electromagnetic field pulses. The disadvantage of this method is the weak effect on the lacrimal gland, which leads to low treatment efficiency.

The closest technical solution to the present invention is a method for the treatment of tear production deficiency in case of dry eye syndrome [3], including electrical stimulation of the eye tissue and initial eversion of the upper eyelid with a passive electrostimulator electrode applied to the skin of the eyelid on a cloth moistened with 0.9% sodium chloride solution at the same time, the electrostimulator moves the active electrode along the eyelid mucosa and transitional fold with preliminary anesthesia with a surface anesthetic, and tears are also aspirated from the inner surface of the eyelid and transitional folds through an opening on the working end of the active electrode, which is connected to the suction tube using a longitudinal channel and acts on the mucosa with a laser stimulating beam with a wavelength of 670 nm.

The known method of treatment is painful for the patient, time-consuming for the doctor and has low efficiency.

The technical result, which consists in increasing the effectiveness of the treatment of keratoconjunctivitis, increasing the stability and durability of the treatment results, is achieved in the proposed method for the treatment of keratoconjunctivitis based on exposure to electromagnetic radiation on the tissues of the eye, in that they are provided by pulsed radiation with a wavelength of 800-1200 nm, continuous radiation with a wavelength of 630-670 nm and a magnetic field with an intensity of H = 20-45 mT, while pulsed radiation is set with an average radiation power P _cf.imp = 1.5-4 , 0 mW, pulsed power P _imp = 1.0-3.0 W, pulsed radiation is carried out with a pulse repetition rate f _imp = 50 Hz, and continuous radiation is set with an average radiation power P _{cf. not} up to 40.0 mW, and the exposure time T _{air by} electromagnetic radiation and a magnetic field is maintained in the range T _air = 5.0-10.0 minutes

Moreover, before each session, the patient is instilled trophic drops.

The specified technical result is achieved in the proposed method also by the fact that in one course of treatment spend from 8 to 10 sessions.

If necessary, the patient is prescribed a repetition of the course of treatment after 1.0 - 2.5 months.

A feature of the proposed method in relation to the known [1, 2] is that new modes of exposure to the electromagnetic field are established, which were determined after research and observation of the condition of patients.

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 analogue of the device [4]).

Example 1

Patient M., age 18 years.

Complaints: discomfort in the eyes, a sharp decrease in distance vision, a feeling of "sand" in the eyes, photophobia lacrimation, eye fatigue, a feeling of pressure inside the eye in the evening.

Case history: vision began to decline sharply in grade 10, began to wear contact lenses.

Diagnosis: keratoconjunctivitis caused by lens wear, accommodation spasm, computer visual syndrome, dry eye syndrome, retinal angiopathy by hypotonic type, tendency to angiospasm.

A course of hardware treatment.

It was carried out lying, before the session - instillation of drops.

The following hardware mode was installed:

- pulsed radiation λ _imp = 800-1200 nm, P _{cf imp} = 2.0 mW, P _imp = 1.5 W, f _imp = 50 Hz;

- _indirect continuous emission λ = 630-670 nm, P _sr.nepr = 20.0 mW;

- magnetic field strength H = 20-45 mT;

- exposure time T _air = 5.0 minutes

After a course of hardware treatment (10 sessions), the phenomena of keratoconjunctivitis significantly decreased. In the course of treatment conducted 10 sessions.

The patient continued to instill anti-inflammatory drops for one month.

Mode: Wearing lenses is contraindicated. Limitation of visual load.

Repeated treatment has completely eliminated the effects of keratoconjunctivitis.

Example 2

Patient G., age 35 years.

Complaints: visual impairment in the distance, eye discomfort, eye fatigue, oppressive pain in the orbit at the end of the day.

Case history: decreased vision from 16 years old, wore contact lenses, up to 15 years old vision was 100%.

Diagnosis: keratoconjunctivitis of both eyes caused by lens wear. Dry eye syndrome.

A course of hardware treatment.

It was carried out lying, before the session - instillation of drops.

The following hardware mode was installed:

- pulsed radiation λ _imp = 800-1200 nm, P _{cf imp} = 4.0 mW, P _imp = 3.0 W, f _imp = 50 Hz;

- _indirect continuous emission λ = 630-670 nm, P _sr.nepr = 40.0 mW,

- magnetic field strength H = 20-45 mT.

- exposure time T _air = 10.0 minutes

After a course of hardware treatment (8 sessions), the phenomena of keratoconjunctivitis practically disappeared.

Mode: Wearing lenses is contraindicated. Limitation of visual load.

After 1 month of a second course of treatment, no keratoconjunctivitis was observed.

Examination of patients after treatment showed that the proposed method allows you to:

- to achieve stability and durability of the treatment result.

The treatment was carried out with the help of a quantum therapy apparatus with expanded functional capabilities, which made it possible to set the modes of electromagnetic radiation in an extended range of parameters, which made it possible to choose the optimal modes for each particular patient.
