To ascertain normative database of contrast sensitivity (CS) using Spaeth/Richman CS test (SPARCS) in the Indian population.
This cross-sectional study enrolled 200 healthy individuals, and CS was tested in both eyes of each participant using SPARCS. A detailed ocular examination was done before enrollment to rule out pathologies that may affect CS. A practice test was performed in the right eye (OD), followed by uniocular testing in each eye and a final binocular test.
Data of 400 eyes of 200 subjects who fulfilled the inclusion criteria was evaluated. The average age of subjects was 46.57 ± 16.77 years (range 21-79 years), with a slight female preponderance (53%, n = 106). A statistically significant decline in average SPARCS scores was noted with increasing age (P < 0.05), ranging from 86.68 (20-29 years age group) to 67.44 (70-79 years age group). Higher scores were noted in binocular testing than uniocular testing (Interclass correlation coefficient [ICC] = 0.83; P < 0.001). Females achieved statistically significant higher total scores in uniocular SPARCS testing (both OD and OS), but there was no significant difference noted between the two genders in binocular testing. Correlation between practice and main tests was statistically Significant with an interclass correlation coefficient of 0.54 (P < 0.001).
Normative database for SPARCS was established for Indian eyes, with a decreasing trend noted in peripheral as well as central CS scores with increasing age.
使用 Spaeth/Richman 对比敏感度（CS）测试（SPARCS）确定印度人群的 CS 正常参考值数据库。
这项横断面研究纳入了 200 名健康个体，使用 SPARCS 测试每位参与者的双眼 CS。在入组前进行详细的眼部检查，以排除可能影响 CS 的病变。先在右眼（OD）进行练习测试，然后分别对每只眼进行单眼测试，最后进行双眼测试。
评估了符合纳入标准的 200 名受试者的 400 只眼的数据。受试者的平均年龄为 46.57 ± 16.77 岁（范围 21-79 岁），女性略占优势（53%，n = 106）。随着年龄的增长，SPARCS 平均得分呈显著下降趋势（P < 0.05），范围从 86.68（20-29 岁年龄组）到 67.44（70-79 岁年龄组）。双眼测试的得分高于单眼测试（组内相关系数 [ICC] = 0.83；P < 0.001）。女性在单眼 SPARCS 测试（OD 和 OS）中获得的总得分显著更高，但在双眼测试中，两性之间没有显著差异。练习测试和主要测试之间的相关性具有统计学意义，组内相关系数为 0.54（P < 0.001）。
为印度人眼建立了 SPARCS 的正常参考值数据库，随着年龄的增长，外周和中央 CS 得分呈下降趋势。
