[Adherence to glaucoma therapy].

Adherence to glaucoma therapy is a major factor of therapeutic efficacy. It reflects the patient's perception of the glaucoma disease and its treatment. Evaluation of adherence, often underestimated, is simple with a four-step strategy underscoring the importance of informing and educating the patient. The quality of the physician-patient relationship is essential for a good adapted assessment with every patient and at all stages of the disease so as to enhance adherence to glaucoma treatment and help patients.
