“…13 The result of a study conducted in the Republic of China shows that male children outnumber female youngsters like the outcomes of recent research study. 14 A significant (p 0.05) positive correlation between family history and color blindness was found in this study. A published study with findings that are consistent with our own suggests that color blindness and family history are strongly correlated.…”

Objective: To Assess and compare different types of color blindness in primary school children also to appraise the self-awareness levels regarding this ailment amongst them. Study Design: Cross Sectional study. Setting: Different Primary Schools of Karachi in Collaboration with Department of Physiology, Jinnah Medical and Dental College Karachi. Period: 1st October 2020 to 1st December 2020. Methods: 146 primary school children of both genders aged between 5 to 12 years were assessed by prescribed questionnaire and Ishahara Chart for color blindness. Result: Out of the 148 students who underwent screening, only 16 were diagnosed with color blindness, indicating a prevalence of 10.8% among primary school children in Karachi. Of these 16 students, males exhibited a higher incidence of color blindness (56.25%) than females (47.35%). Conclusion: The incidence of color blindness is higher in males than females with significant association with family history and night blindness. Colour blindness unawareness also significantly found in this study. It is recommended to have an eye checkup at the start of school and to have regular eye examination to avoid any hindrances and get the right help.

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.
