Clinical and Physiological Rationale for the Use of Ophthalmochromotherapy in the Complex Rehabilitation Treatment of Patients with Visually Intense Work with Accommodative Asthenopia

Purpose . Clinical and physiological substantiation of the use of ophthalmochromotherapy in the complex restorative treatment of patients with visually intense work (VIW) with accommodative asthenopia (AA). Methods . We observed 22 volunteer test subjects (males aged 22–24 years, average age 22.2 ± 0.4 years) with the following inclusion criteria for the study: no visual organ pathology, normal color perception, microfluctuation coefficient of the ciliary muscle of the eye (CMF) according to objective accommodation data (on the Righton Speedy-I device, Japan) from 53.0 to 58.0 relative units, which corresponds to the “norm” and indicates the absence of habitual excess accommodation tension (HEАT) or asthenic form of accommodative asthenopia (AFAA), absence of subjective manifestations of AA. Each of the test subjects underwent a CT session on the ADFT-4 RAINBOW device. The variable parameters during the study were color (red, yellow, green, blue) and stimulus presentation time (10, 20, 30 min.), a total of 12 single impacts performed on different days, while the time and color parameters of the stimulus were changed randomly. The CMF index was recorded before and after each single impact (monocularly). Results . Pronounced, statistically significant changes were found in relation to stimulation with red and green colors. It was determined that stimulation with red color increases CMF, while stimulation with green color decreases this indicator, and in both cases a very high frequency of occurrence (91–95 %) of the revealed dynamics in specific patients is noted. Conclusion . The results indicate the prospects for the use of CT in the complex restorative treatment of patients with VIW with AA phenomena. A multidirectional nature of the effect of red color (stimulation of the accommodative muscle) was established compared to green color (relaxation). In the framework of further studies, it is advisable to evaluate the use of green color in patients with HEАT and, accordingly, red color in patients with AFAA. In this case, the exposure time (taking into account the time of the traditional approach to restorative treatment and the general principles of the impact of physical factors on the body) should not exceed 20 minutes.
