A method for the treatment of partial atrophy of the optic nerve

 

(57) Abstract:

The invention relates to ophthalmology. The method includes the stimulation pulse current to the nasal and temporal areas of the eyes. Then irradiate the retina radiation at wavelengths of 650 and 910 nm through the day. Then affect the area of both eyes of the electromagnetic field at the closed eyelids. The method allows to consistently improve visual function.

The invention relates to ophthalmology, and can be used for the treatment of partial atrophy of the optic nerve.

Known "Method of treatment of diseases of the optic tract by means of electrical stimulation and device for its implementation" RF patent N 2054909, A 61 F 9/00, is the impact of pulsed electromagnetic field on the eye area.

However, this method has a significant drawback, it is not effective enough.

The technical problem solved by the invention is to increase efficiency by improving visual functions.

The specified technical task is solved in that in the method for the treatment of partial atrophy of the optic nerve, which consists in the implementation of the electromagnetic field is aciu pulsed current with an amplitude of from 40 to 100 µa, pulse duration 30 - 60 μs, a frequency of 60 Hz, number of pulses in pacce 4-6, the repetition rate of the stack of 7-8 pulses per second, the exposure duration of 12 to 14 seconds, then irradiated retina radiation Nd: YAG laser with a power density output from 3 - 5 mW at a frequency of 60 Hz, the exposure duration from 5 to 7 minutes, alternately: wavelength = 650 nm and = 910 nm, through the day, then act simultaneously on the area of both eyes at the closed eyelids of a pulsed electromagnetic field with a voltage of 0.8 to 0.9 T, pulse duration of 25 - 38 μs, when the number of pulses from 70 to 95 with the duration of the pause from 0.6 to 0.8 μs and the duration of exposure from 4 to 7 minutes.

Proposed by the author of the essential distinguishing features of the present invention is necessary and sufficient for an unambiguous positive solution to the stated technical problem.

The author has done a lot of research work on the optimization of the intervals stated parameters. This work has shown that when the values of the parameters, these smaller or larger than specified in the parameter intervals, the positive growth effect does not occur.

The invention is carried out as follows.

The method is illustrated in the following clinical examples.

Example 1. Patient B., 32, was in the clinic with a diagnosis of partial atrophy of the optic nerve. Three years ago, I was in a car accident, got a brain contusion, blunt cranial trauma treatment in neurosurgical clinic a month and a half the vision in the left eye increased from 0.01 n/a to 0.04 n/a, the vision of the right eye and 1.0, the intraocular pressure is normal. The fundus of the left eye: optic disc is pale with a grayish tint, macular region and the periphery without pathology, field of vision of the right eye is not changed, the field of vision of the left eye narrowed to the point of fixation with nasal side and the 30oin niininen quadrant. Thresholds electrical sensitivity and electrical lability could not be detected due to spontaneous Fofana. Diagnosis: post-traumatic descending atrophy of the optic nerve of the left eye. Patients received treatment proposed by the author of the way. After the first course of treatment, which consisted of 15 sessions were improved vision from the source from 0.04 to 0.4. Expanded peripheral border of the field of view 70o. The threshold electric sensitivity in my left eye 120 µa, electrical lability 27 Hz. With repeated follow-up at three months, the vision improved to 0.5. The patient was held the second and third courses of treatment with an interval of 3 and 6 months. The vision in the left eye after treatment was 0.85. A year and a half vision remained at this level without changes. Thus the proposed use is Patient R., 58 years of age, was treated with a diagnosis of partial atrophy of the optic nerve after circulatory disorders. When receiving the vision of the right eye of 0.7, the vision in the left eye 0,06 n/K. the fundus of the right eye was normal. The fundus of the left eye: optic disc pale, minor excavation, the arteries narrow and winding. In the macular region: minor degenerative lesions. Field of the left eye concentrically narrowed to 20o. The threshold electric sensitivity of 40 µa, electrical lability 16 Hz. The treatment proposed by the author of the way. Conducted three courses with an interval of 3 months. After treatment, the visual acuity of the left eye improved to 0.3. The threshold electric sensitivity 78 μa, the threshold electric lability 30 Hz. The peripheral border of the field of vision expanded on 20o. Conclusion: the positive dynamics are stable for one year, there has been a significant improvement of visual functions.

Using the proposed method with pre-clinical testing for the treatment of 102 patients with partial atrophy of the optic nerve showed its high effectiveness and unique achievement of improvement of visual functions.
