BACKGROUND: For the diagnosis of dry eye, taking an accurate medical history of the patient is critical. For this purpose the ocular surface disease index (OSDI) can be regarded as the established standard questionnaire but the standard patient evaluation of eye dryness (SPEED) questionnaire has recently been developed. The advantages of the SPEED questionnaire are the lower number of questions and easier interpretability. MATERIAL AND METHODS: In a retrospective analysis of 153 patients of our special clinic for dry eyes we performed a comparison of the SPEED with the established OSDI questionnaire regarding the evaluation of the severity of dry eye. In addition, we analyzed possible correlations with various objective parameters for classification of dry eye syndrome. RESULTS: There was a highly significant correlation between OSDI and SPEED values with a correlation coefficient of 0.47 (p < 0.001). In addition, significant correlations between OSDI values and the tear meniscus height (r = - 0.1374, p = 0.0226), Schirmer values (r = - 0.26, p < 0.0001) and lid margins parallel conjunctival folds (r = 0.1261, p = 0.034) were observed. The SPEED values showed a significant correlation with age (r = - 0.2106, p = 0.0107) and lipid layer thickness (r = - 0.159, p = 0.0081). DISCUSSION: The OSDI and SPEED questionnaires are both suitable for detecting the symptoms of dry eye; however the results of the questionnaires cannot be used interchangeably. While the SPEED levels seemed to correlate more with the parameters of evaporative dry eye, the OSDI values were more correlated with parameters of aqueous tear-deficient dry eye. However, a distinction between evaporative and aqueous tear-deficient dry eye is not possible based only on the results of the questionnaires.
