Methods: 30 patients were randomized to receive kohl from Saudi Arabia in one eye and erythromycin ointment in contra lateral eye for 90 days. At baseline and during 30 and 90 days of treatment, symptoms, clinical signs and side effects of treatments were recorded. Statistical analysis was carried out using SPSS software, version19. Results: There was also a significant difference between intervention and control eyes in baseline mean clinical score (intervention eye: 9.86( 2.95) and control eye: 4.30(2.81), P <.001). The degree of reduction of related signs and symptoms in eyes treated with kohl was significantly higher than that in the control group (5.2 vs. 2.20 ,P <.001) for symptoms and (7.40 vs. 2.46, P <.001 for clinical signs). Conclusion: The results of the present study demonstrated a significant improvement in blepharitis related signs and symptoms in both treatment and control eyes. The degree of improvement in eyes treated with kohl was much higher than that in control eyes.
