Transcultural Validation of the Five-Item Dry Eye Questionnaire for Indonesian Populations.

Purpose Indonesian dry eye (DE) disease (DED) prevalence data remain scarce, and Indonesian validations of the five-item Dry Eye Questionnaire (DEQ-5) are unavailable. We aimed to translate and validate an Indonesian language adaptation of the DEQ-5 (INDO-DEQ-5) for local populations. Methods Our observational study involved linguistic validation of the translation, reliability testing, dataset screening, and data collection through ophthalmic examinations and interviews.
