Relationship between Signs and Symptoms for the Assessment of the Lacrimal Function and the Ocular Surface in Colombian and Spanish Subjects without Apparent Ocular Pathology
Relationship between Signs and Symptoms for the Assessment of the Lacrimal Function and the Ocular Surface in Colombian and Spanish Subjects without Apparent Ocular Pathology
<em><strong>Objective:</strong></em> To find a link between the symptoms and signs found when assessing lacrimal function and ocular surface with dry-eye diagnostic tests in a group of apparently healthy Colombian and Spanish subjects. Method: A total of one hundred healthy subjects (fifty Colombians and fifty Spaniards) without previous history of contact lenses were recruited and evaluated. The subjects answered a McMonnies dry-eye questionnaire and were subjected to the Non-Invasive Break-Up Time (NIBUT), Tear Film Breakup Time (TFBUT), fluorescein staining, lissamine staining and impression cytology (IC) tests. For the statistical analysis, the Pearson correlation and multiple statistical tests were used. <em><strong>Results:</strong></em> The McMonnies questionnaire did not corroborate individual findings, even though the signs and tests determined dry-eye. Significant differences between the two population groups were found (p = 0.016). No correlation was found between McMonnies and the NIBUT, TFBUT, fluorescein and lissamine green staining and IC tests. <em><strong>Conclusion:</strong></em> The McMonnies questionnaire, by itself, is not a useful test in the diagnosis of ocular surface Disease.
