ABSTRACT
AIM OF THE STUDY: Cilostazol is a phosphodiesterase III inhibitor that has anti-inflammatory and immunomodulatory effects and can act with beneficial effect in Dry Eye Syndrome (DES). This clinical trial evaluates the effects of cilostazol on the tear film. MATERIALS AND METHODS: Following the run-in period, subjects were randomly into two groups: 40 subjects treated with cilostazol and 40 no-treated subjects. The Walking Impairment Questionnaire (WIQ) has been administered to all patients. RESULT: The data obtained from comparison of the two study groups A and B were, respectively, the following: Schirmer I: 10.2±0.2 Vs 13.8±0.4 (p< 0.001); Schirmer II: 3.8±0.1 Vs 4.6±0.2 (p<0.001); Break-up time (BUT) 4.2±0.3 Vs 6.5±0.2 (p<0.001) with disappearing of symptoms. The WIQ showed a significant difference in the walking distance (p<0.05) and calf pain severity (p<0.005) of treated patients. In comparison with the placebo group, treated patients showed an improvement (p<0.03) in calf pain severity. CONCLUSION: The administration of cilostazol was effective, in reducing DES and improve walking distance questionnaire.
