BACKGROUND: Poor compliance can be dangerous to successful medical treatment of glaucoma. Among other things one reason for non-compliance represents the inability of the patients to place drops in the eye appropriately. Therefore information regarding the patients ability to administer an eyedrop safely are a prerequisite to determining a therapy scheme which ensures the compliance of glaucoma patients. PATIENTS AND METHODS: 100 glaucoma patients on medical therapy who first presented in the outpatient glaucoma clinic of the University Eye Hospital of Würzburg were examined by standardised questionnaire and ability tests. We evaluated: 1. Can the eyedrop administration of glaucoma patients be improved by a standardised instruction? 2. Can the eyedrop administration be improved by the use of a drop aid (Autodrop)? 3. Can the accuracy of aiming and the manual ability be evaluated with a target-test on a sheet of paper with a series of concentric circles? 4. How do patients on combined therapy distinguish between their different bottles and where is the dosage regimen noted? 5. What kind of distinguishing marks of eyedrop-bottles do the patients prefer? RESULTS: 1. Before verbal instruction 76% of the patients applied the eyedrops appropriately, after instruction 94% (p < 0.001) were capable. Touching the eye with the tip of the dropper was reduced significantly. Touching the eye before instruction was found in 63% of the patients, after instruction it was found in 41% (p < 0.001). 2. When patients used the drop aid 81% were able to place a drop in the eye appropriately. Only by 46% of the patients the Autodrop was welcomed. 3. 16% of the patients were not able to place a drop within 1.5 cm of the center of the target (according to the size of an eye). 4. 47% of the patients who use more than one eyedrop bottle admitted problems in distinguishing the bottles, only 38% of the patients read the labels. 5. 76% of the patients would prefer markable stickers of different colours for the bottom of the bottles to improve distinguishing the bottles in combined therapy. CONCLUSION: Instruction improves eyedrop administration in 18% of our patients. In combined therapy with several drugs new distinguishing marks are requested by the patients. To improve compliance combination preparations should be administered if available.
