Purpose: : To advice the mean variety of drops every bottle and also mean separation, personal, instance eye autumn volume in a 2.5ml party of travoprost 0.004% and to to compare the variability of this values between five different subjects.

Methods: : Ten party of 2.5 ml travoprost 0.004% to be evaluated in the hands of 5 healthy subjects. Using their leading hand, topics were instructed come expel one autumn onto a weighing plate calibrated to 0.1 µg. The angle of the elbow and bottle were similar to self-administration the eye drops. The quantity of every drop to be measured, and also the process repeated till the bottle was empty. The total number of drops per bottle was recorded. Party was recapped after every also numbered drop to simulate patient use of medicine bilaterally. Once the bottle was empty, the subject repetitive the procedure v the non-dominant hand. Topics were masking to all measurements.

Results: : Mean variety of drops expelled per bottle ranged from 84 come 105 and the difference in between subjects was discovered to be statistically significant (p by all topics with leading hand to be 92.8 and with non-dominant hand to be 93.2; the distinction was not statistically far-ranging (p=0.89). In its entirety mean volume of individual drops expelled per topic ranged indigenous 24.5 µl to 28.9 µl; this distinction was uncovered to be statistically significant between the topics (p by all subjects with dominant hand was 27.7 µl and also with non-dominant hand to be 27.6 µl; this difference was no statistically far-reaching (p=0.74). In four out of 5 subjects, there to be no far-reaching difference in number or volume of separation, personal, instance drops when they provided their leading or non-dominant hand.

Conclusions: : Prostaglandin analogues such as travoprost are typically the initial choice in glaucoma treatment. How long the bottle of medication lasts varies in between patients, through some running the end of medication within 2-3 weeks, others lasting more than a month. Currently there is little published data ~ above the variety of drops or average individual eye fall volume in prostaglandin analogues. We uncovered a statistically far-ranging difference between variety of drops per bottle and also a statistically far-reaching variability in the volume of drops expelled by every of the 5 subjects using 2.5ml bottle of travoprost 0.004%. Based upon these results, the dose of medicine administered and also length of time a bottle lasts will certainly vary between patients.
