Abstract
Purpose:
The purpose of this study was to assess 3 questionnaires for diagnosis of Ocular Surface Disease (OSD) in a Tertiary Care Ophthalmology Center in Mexico City.
Methods:
120 consecutive patients seen in an ophthalmologic center in Mexico City for the first time from September 2013 to November 2014 underwent a comprehensive examination, including measurement of tear film break-up time (TBUT), fluorescein staining classified by Oxford scheme, and Schirmer test type 1. Symptoms of OSD were evaluated by the Ocular Surface Disease Index (OSDI), Dry eye Questionnaire (DEQ-5) and McMonnies questionnaire. Symptomatic OSD was defined as having an OSDI score ≥55, DEQ-5 score ≥12, or Mcmonnies >14. Clinical OSD was defined as having a Schirmer test <5, TBUT <5, or staining >1.
Results:
Mean patient age was 41.86 (±16.4) years (range, 18-80); 64 (53.3%) patients were female. The frequency of symptomatic OSD based on the OSDI score ≥55 was 21.7%, DEQ-5 was 24.2%, and Mcmonnies was 21.7%. Frequency of patients with two positive signs and one positive questionnaire was 11.7% with OSDI score ≥55, 18.3% with DEQ-5, and 15% with McMonnies. McMonnies and DEQ5 questionnaires had a moderate correlation wirh one another, and OSDI a low correlation compared to the other questionnaires (p-value <0.05). McMonnies and DEQ5 questionnaires are more sensitive than OSDI questionnaire.
Conclusions:
This is the first study to assess 3 questionnaires for diagnosis of Ocular Surface Disease in a Tertiary Care Ophthalmology Center in Mexico City. Frequency of OSD based on questionnaire, and two signs plus one positive questionnaire were really close to one another.
