Контрастная чувствительность и контрастность как критерии утраты качества зрения при некоторых заболеваниях сетчатки

Abstract

Contrast sensitivity (CS) better correlates with subjective visual impairment and visionrelated quality of life compared with visual acuity (VA). Scleral lenses (SL) are a promising approach in the rehabilitation of patients with AMD, as they have a number of functional and cosmetic advantages. Despite the available types of SL, the search for possible modifications to improve the quality of life of patients with AMD continues. Purpose. To evaluate the effectiveness of contact correction using color filters to improve contrast sensitivity in patients with AMD. Material and methods. In the first group of patients with AMD, 64 % (218 patients, 267 eyes) were diagnosed with the dry form, 36 % (123 patients, 174 eyes) were diagnosed with neovascular AMD (nAMD), of which 87 patients (94 eyes) received anti-VEGF therapy or completed it and are under monthly monitoring without signs of MNV activity. The SpethRichman (SPARCS) and Pelly-Robson tests were performed with and without soft contact lenses ACUVUE OASYS with Transitions. Results. In group nAMD a statistically significant increase was revealed from 13.48 ± 1.56 % to 15.2 ± 2 % according to the SPAPCS test (p = 0.03) and the overall CN from 1.58 ± 0.16 to 1.75 ± 0.08 logarithmic units according to the Pelly-Robson test (p = 0.005). In the subgroup of dry AMD, there was no significant increase in CS when using contact lenses. Conclusion. Contact correction using color filters in patients with nAMD without signs of MNV activity can improve the CS in the central zone, but due to the instability of the soft lenses color filter, the study of other correction methods using color filters, such as SL.
