Adaptation culturally and linguistically to the Chilean population and validation the Dry Eye Questionnaire 5.

Background And Objective: There are different methods for evaluating dry eye disease (DID), including questionnaires that analyze different aspects of its symptoms, which are important for its better understanding and therapeutic management. The Dry Eye Questionnaire 5 (DEQ-5), is unique in its kind, because in addition to its simplicity, it measures symptoms in 4 dimensions. The aim of this study is to adapt culturally and linguistically and validate this instrument to the Chilean population.

Dry Eye and Visual Display Terminal-Related Symptoms among University Students during the Coronavirus Disease Pandemic.

Purpose: To evaluate dry eye (DE) and subjective visual display terminal (VDT)-related symptoms in university students who moved their classes online due to the COVID-19 pandemic.

Methods: Cross-sectional study of students who were taking online classes. In May 2020, the participants completed a Dry Eye Questionnaire (DEQ-5) and a self-report survey, which included demographics, medical history, information on the use of VDT and presence of VDT-related symptoms.

High frequency of digital eye strain and dry eye disease in teleworkers during the coronavirus disease (2019) pandemic.

This study aimed to evaluate visual display terminal (VDT)-related digital eye strain (ES) and dry eye disease (DED) symptoms in subjects whose work was changed to teleworking (TW) during the coronavirus pandemic. A digital self-reported survey was conducted on subjects in TW, including demographics, medical history, VDT time and ES-related symptoms before and during the pandemic and DED (dry eye questionnaire 5 [DEQ-5] questionnaire). A total of 1797 questionnaires were analyzed.

[Validation of the Ocular Surface Disease Index Questionnaire for Chilean patients].

Background: Ocular Surface Disease Index (OSDI) is the most commonly used questionnaire worldwide to detect dry eye disease. Although it is massively used in clinical practice in Chile, its use has not been validated yet in the country.

Aim: To develop a cultural adaptation and to validate the OSDI questionnaire for the Chilean population.

Dry eye is matched by increased intrasubject variability in tear osmolarity as confirmed by machine learning approach.

Objective: Because of high variability, tear film osmolarity measures have been questioned in dry eye assessment. Understanding the origin of such variability would aid data interpretation. This study aims to evaluate osmolarity variability in a clinical setting.
