Volumetric and cost evaluation study of glaucoma medical therapy

摘要

Aim:The aim of the study was to evaluate the difference in mentioned volume and measured volume of the eye drops and to find out the yearly cost of various antiglaucoma drugs.Methods:It was an experimental and purely laboratory study. Total of 245 bottles of 49 different brands, five of each brand of antiglaucoma drug were analyzed. Number of drops were counted, and volume was measured from each bottle. On the basis of data collected yearly cost of each brand was calculated.Results:Of the 245 bottles, 152 bottles (62.04%) had underfilling. Yearly cost of most of the antiglaucoma drugs lies between Rs. 423.40 and Rs. 6263.40.Conclusion:Measured volume and drops are the major determinants of the cost of medical therapy of glaucoma. Most of the bottles showed underfilling and it was the significant finding. Less number of drops and lesser volume increases the cost of treatment indirectly.
