Summary
This study investigated color blindness in Jat Sikhs in Patiala. The incidence was 3.83% in males and 0.13% in females, with simple and extreme deuteranomaly being most common in males.
Area of Science:
- Ophthalmology
- Genetics
- Population Health
Background:
- Color blindness, a common visual impairment, has varying prevalence across different populations.
- Understanding the genetic and demographic factors influencing color blindness is crucial for public health initiatives.
Purpose of the Study:
- To determine the incidence and types of color blindness in the Jat Sikh population of Patiala city and surrounding villages.
- To compare the findings with other Indian and European populations.
Main Methods:
- A cross-sectional study was conducted on 1306 males and 791 females aged 10-60 years.
- Ishihara Charts and Pickford Nicolson's anomaloscope were used for color vision testing.
Main Results:
- An overall incidence of 3.83% for males and 0.13% for females was observed.
- The most common types in males were simple deuteranomaly (0.92%) and extreme deuteranomaly (0.77%).
- The sole color-blind female had simple deuteranomaly.
Conclusions:
- The incidence of color blindness in Jat Sikh males in Patiala is comparable to other Indian populations but significantly lower than in European populations.
- Deuteranomaly is the predominant type of color vision deficiency in this cohort.
