Comparison of Efficacy and Ocular Surface Disease Index Score between Bimatoprost, Latanoprost, Travoprost, and Tafluprost in Glaucoma Patients

Figure 2

Different OSDI scores of patients treated with different prostaglandins. The three dashed lines represent the three subscales analysed to obtain a final OSDI score: vision-related function, ocular symptoms, and environmental triggers. A value <0.05 is marked by an asterisk. OSDI indicates ocular surface disease index; N, M, and M0 represent, respectively, normal, mild, and moderate eye disease as defined by both physician’s assessment and a composite disease severity score; POAG: primary open-angle glaucoma.
