“…Между тем эффективная диагностика цветового зрения у пациентов разного возраста с офтальмопатологией осложнена тем, что, несмотря на свою простоту и доступность применения, многие существующие способы (табличные тесты, некоторые компьютерные программы, упрощенные панельные тесты ранжировки цветов) дают возможность только качественной, а не количественной оценки нарушений цветового зрения, что снижает информативность их применения в мониторинге. Другие методы (аномалоскопия, цветовая кампиметрия, регистрация ЭРГ и ЗВП на цветовые стимулы) предназначены в основном для диагностики цветового зрения взрослых и детей старшего возраста или требуют специального оборудования [9][10][11][12][13][14][15][16][17][18][19].…”

Background. Congenital partial atrophy of the optic nerve is one of the main causes of blindness and low vision in patients with fundus pathology, and the study of color vision is important in diagnosis and monitoring visual functions in patients with this disease.Purpose: to study the possibilities of using the own developed method of quantitative and qualitative assessment of color vision in patients with partial optic nerve atrophy.Materials and methods. 55 patients aged from 8 to 20 years with congenital partial atrophy of the optic nerve (PAON) with a typical fundus pattern and EFI indicators for this disease were observed. The control group included 116 people of the same age without fundus pathology and with normal visual acuity. To study color vision in both groups, the classic FarnsworthMunsell Dichotomous D15 Test and the own developed method for quantitative and qualitative assessment of color vision were used.Results. The method developed by us made it possible to identify color perception disorders of varying severity in the majority (about 90 %) of patients with PAON. In the control group, no color perception disorders were detected in more than 70 % of the subjects. Quantitative assessment of color vision conducted using the method developed by us demonstrates significantly higher indicators of the total error of perception of color tones in patients with PAON (35.6 ± 3.2 degrees for a better-seeing eye and 39.9 ± 3.3 degrees for a worse-seeing eye) in comparison with the subjects of the control group (6.2 ± 1.1 degrees for a better-seeing eye and 7.5 ± 1.3 degrees for a worse-seeing eye). The severity of color perception disorders in patients with PAON does not depend on age, but has a significant inverse relationship with visual acuity. In the group of patients with PAON, when examining both better-seeing eye and worse-seeing eye, perception disorders of all color tones are detected with a slight predominance of disorders of perception of red, green and blue. The method developed by us has sufficiently higher sensitivity and specificity in comparison with the classic Farnsworth-Mansell D-15 test.Conclusion. The method developed by us makes it possible to effectively carry out a quantitative and qualitative assessment of the state of color perception in patients with PAON.

PurposeTo assess the repeatability of various color‐measuring mobile phone applications (MPAs) on dental materials in clinically relevant shades in 1‐mm thickness.Materials and MethodsA benchtop spectrophotometer was used as a reference instrument. Seven MPAs were used: Color Analysis, Color Analyzer—Iro Shirabe, Color Grab, and Colorimeter from Android, and Color Analyzer—Iro Shirabe, ColorMeter RGB, and Optishade from iOS. Color measurements were performed on 1‐mm thickness slices of CAD‐CAM materials, Vita Enamic shades 1M2, 2M2, 3M2, 4M2, and Vitablocs Mark II shades A1C, A2C, A3C, A4C (n = 10, for a total 80 specimens). The specimens were measured at three time periods, Day 0, Day 1, and Day 7, and three measurements were made on each day, to mimic short‐, medium‐, and long‐term repeatability. The color differences were analyzed using the CIEDE2000 formula, with the corresponding color difference (ΔE00), and mean color difference from the mean (MCDM00). One‐way ANOVA, Repeated measures ANOVA, and Paired sample t‐tests were used for statistical analysis.ResultsOptishade from iOS showed the lowest mean color difference among the MPAs (ΔE00 = 0.2 (SD 0.1), 0.3 (SD 0.2), and 0.2 (SD 0.1) at Day 0, 1, and 7, respectively, and ΔE00 = 0.5 (SD 0.3) for all three periods Days 0–1, 0–7, and 1–7). Material‐dependent variations in the repeatability of color measurements were observed.ConclusionThere was a statistically significant difference among color measurements using MPAs and a spectrophotometer, among the MPAs, and materials. The spectrophotometer exhibited the highest repeatability across the tested time periods. The iOS Optishade showed the highest repeatability among the MPAs.

BACKGROUND Telemedicine applied to ophthalmology has been developed since 1960s, however, it only had a greater evolution and a wide-scale implementation in 2020 with the coronavirus pandemic (COVID-19). Since then, dozens of software and applications have been developed to evaluate different aspects of visual function. OBJECTIVE This study aimed to evaluate the application of tests carried out through telemedicine to evaluate visual acuity, color vision, and visual field in patients of all Brazilian regions METHODS An observational, cross-sectional, and retrospective study was carried out. A convenience sample was made up of patients evaluated by the Eyecare Health clinic via telemedicine between the months of October 2023 and January 2024. All these patients evaluated via telemedicine were employees of a multinational evaluated in an occupational context (admission, periodic and dismissal consultations). The inclusion criteria was age over 18 years old and the exclusion criteria were incomplete or unavailable medical records. All patients performed three online tests: Best Corrected Visual Acuity (Eyecare Visual Acuity Test ®), color test evaluation (Eyecare Color Vision Test®) and remote confrontation perimetry. Data analysis was performed on DATAtab Online Statistics Calculator (2023, Austria). Data were described as measures of frequency, absolute numbers, percentages, mean, and standard deviation (when applicable). RESULTS 2197 patients from all Brazilian regions were evaluated. 91.81% were male and the mean age was 37 years. 17.10% had never undergone an ophthalmological evaluation. The mean visual acuity evaluated by Eyecare Visual Acuity Test ® was 0.2logMar for both eyes (± 0.16). Eyecare Color Vision Test® detected a prevalence of 2.28% of color vision deficiency. Confrontation perimetry showed 3.23% of visual field defects. CONCLUSIONS Tele-ophthalmology has proven to be an important ally in the widespread access to eye health, especially in countries or regions with unequal access to health services. In our study we assessed remotely 2197 patients and performed visual acuity test, color vision test, and remote confrontation visual field. We found a mean visual acuity of 0.2logMar for both eyes, 2.28% prevalence of color vision blindness and 3.23% of visual field defects. These findings reaffirm and highlight the importance of tele-ophthalmology in the detection and screening of ophthalmological diseases.
