PURPOSE: To check the effect of correct eyedrop instillation on the intraocular pressure of chronic glaucoma patients. METHODS: Prospective study with 90 eyes of 47 patients. A diurnal tension curve was performed before, and a second one after each patient was taught how to correctly instill eyedrops. The mean intraocular pressure values obtained in each tension curve were then compared. RESULTS: There was asignificant 22.3% drop in the mean IOP levels of 35 (38.9%) eyes. Of the remaining, 35 (38.9%) showed a slight fall (-8.2%), and 20 (22.2%) a slight increase (+8.4%), both not statistically significant. CONCLUSIONS: It was noted that an expressive part of the studied population obtained an additional fall in their mean intraocular levels by correctly instilling the eyedrops. Therefore, it is necessary to teach all patients on how to correctly perform eyedrop instillation, as that may result in an extra benefit to those using ocular hypotensive drugs.
