Summary
This study establishes a contrast sensitivity (CS) database for the Indian population using the Spaeth/Richman CS test (SPARCS). CS scores decline with age, with higher scores in binocular testing.
Area of Science:
- Ophthalmology
- Optometry
- Vision Science
Background:
- Contrast sensitivity (CS) is crucial for visual function.
- Establishing normative data is essential for diagnosing visual impairments.
- The Spaeth/Richman CS test (SPARCS) is a validated tool for CS assessment.
Purpose of the Study:
- To ascertain a normative database of contrast sensitivity (CS) using the Spaeth/Richman CS test (SPARCS) in the Indian population.
- To investigate the influence of age and gender on CS in healthy Indian adults.
Main Methods:
- A cross-sectional study enrolled 200 healthy Indian individuals.
- Contrast sensitivity was assessed using the Spaeth/Richman CS test (SPARCS) in both eyes.
- Ocular health was confirmed through a detailed examination prior to testing.
Main Results:
- A normative database for SPARCS was established for Indian eyes.
- Average SPARCS scores significantly declined with increasing age (P < 0.05).
- Binocular testing yielded higher scores than uniocular testing (ICC = 0.83).
Conclusions:
- A normative database for SPARCS was established for the Indian population.
- Peripheral and central CS scores decrease with advancing age.
- Gender differences were observed in uniocular, but not binocular, CS testing.
