Many factors affect the adherence to therapy in glaucoma patients.One of these factors being size of thedrop administered. Big drop size not only leads to early exhaustion of medication but also causes unwanted adverseeffects. This study was done to find out the drop size of commonly used anti-glaucoma eye drops. Material andmethods: Four commonly used eye drops were included in the study:Timolol 0.5%,Brinzolamide 1%,Brimonidine 0.2%and Bimatoprost 0.03% eye drops.Three bottles of each drug was taken.The bottles were emptied in a 10 ml graduatedcylinder drop by drop.The total volume and number of drops were noted,and drop size was calculated.Result:The dropsize for Timolol, Brinzolamide, Brimonidine and Bimatoprost was 38.62 µl, 43.09 µl, 45.87 µl and 39.19 µl respectively.Conclusion:The drop size of anti-glaucoma medications can further be reduced and this may lead to improved patientcompliance and reduce the adverse effects
