RESUMO
The article presents review of scientific publications on development of laser treatment methods in vitreoretinal surgery. The use of photo-therapy in medicine dates back to ancient times, when people began to use sunlight as treatment of various diseases. The heyday of photo-therapy falls on the second half of the XIX century, which was associated with the invention of first electric lamps. In 1960, T. Maiman developed the world's first laser, revolutionizing precision and control of light delivery. This was the beginning of heyday of laser surgery primarily in ophthalmology, where potential of lasers was instantly recognized. The subsequent discovery of argon laser in 1964 by W. Bridges (USA) marked new era in retinal photo-coagulation. Then new types of lasers with various systems of delivering laser radiation appeared that significantly expanded range of application of laser technologies in ophthalmology and vitreoretinal surgery. Currently, the lasers are applied in oculoplasty, refractive and corneal surgery, in laser support of phacoemulsification of cataract, in treatment of glaucoma, in laser coagulation of retina and thermotherapy. In vitreoretinal surgery laser technologies remain at the level of the XX century. Thus, they are still applied only for endolaser coagulation of retina. And this despite the fact that there is immense potential for applying lasers as "laser scalpel" to remove vitreous humor, epiretinal fibrosis, retinotomy and choroidotomy.

Age-related macular degeneration (AMD) is currently the leading cause of vision loss in the elderly population worldwide. Despite the experience of using physiotherapeutic methods of treatment for non-exudative form of age-related macular degeneration, as well as the lack of clear criteria for its indication and evaluation of its effectiveness, the question of its advisability remains open. PURPOSE: Evaluation of the effectiveness of rehabilitation complex involving physiotherapy in the form of infrared and magnetic stimulation of the retina, aerogenation with Heliox21 and dry needling in patients with non-exudative AMD (drusen). MATERIAL AND METHODS: The study included 84 patients (168 eyes), among them 50 men and 74 women with stage 1 non-exudative AMD, aged 60 to 70 years old (average age 60±3.7 years), who were divided into 2 groups with comparable clinical and functional characteristics. Group 1 included 42 patients (84 eyes) who underwent ophthalmic neurostimulation consisting of daily infrared-magnetic stimulation of the retina for 10 days, 10 procedures of daily aerogenation with Heliox21 and 10 daily procedures of acupuncture. Group 2 included 42 patients (84 eyes) who received only basic parenteral therapy (Nutrof forte 1 tablet per day during the entire observation period), which was also the medication background in the main group. Visual acuity (VA), retinal OCT parameters, local photosensitivity and bioelectrical potential indices were assessed with mfERG. The control time points were before therapy, after 2 weeks, 3 months, 6 months and 12 months. RESULTS: After undergoing therapy with the described physiotherapeutic regimen, a positive effect on functional characteristics was noted - the level of light sensitivity of the central zone of the retina and the amplitude of the electrical biopotential have improved. The indicators of maximally corrected visual acuity and the structure of the ellipsoidal zone of the retina and the choroid did not change during the entire observation period. CONCLUSION: In patients with non-exudative form of AMD the developed ophthalmic rehabilitation complex involving infrared-magnetic stimulation of the retina, aerogenation with Heliox21 and dry needling promotes improvement of functional characteristics of the central retina in the form of increased maximal light sensitivity of the central retinal area and increased amplitude of bio-electrical potential.
