Sakiyalak D, et al. - Researchers sought to determine the features of the patients who preferred using the eye drop guide (EDG) regularly and their opinions toward the guide in order to select the patients for prescribing the EDG appropriately. Fifty-seven patients with glaucoma who completed the primary study, “The effect of ‘eye drop guide’ on the success rate of eye drop self-instillation in glaucoma patients”, were involved. EDG should be selectively administered for patients who have had one medication and have instilled it in a sitting or standing position. While daily EDG users appeared to have positive opinions on the EDG, their long-term compliance with the guide has been under-researched.
