A large number of people do not use eye drops as prescribed. Glaucoma is a slowly progressive eye disease, which can result in severe vision loss. Drops prescribed for raised eye pressure or glaucoma are aimed at lowering the pressure to assist in reducing the rate of progression, or preventing the conversion of raised eye pressure to glaucoma. It is important that these eye drops are used continually, usually for life. Approximately 70% of people who are prescribed eye drops for the first time, fail to continue collecting prescriptions within the first year and even when patients collect prescriptions they do not always use the drops as frequently as they should. A number of reasons are thought to be the cause, for example, forgetfulness, being prescribed a large number of medications, difficulties instilling drops, a busy lifestyle and seeing no benefit.
This review is based on eight studies that tried out different methods to help people to use drops as prescribed. The following interventions were included; simplifying drop routines, reminder devices, providing information about glaucoma and offering advice regarding day to day issues with eye care. Five of the eight studies showed that these interventions helped people take their eye drops reliably. Unfortunately, not all of these studies were of high quality and, therefore, until more evidence is available we cannot recommend any particular method. Good quality research is needed in this area in order to develop a better understanding of patients' individual needs and to help us provide more effective eye care services.
