This paper reports patient perceptions of inequities in the doctor-patient interaction. A mixed method study was conducted in a tertiary eye care centre in southern India to gain an insight into patient understanding and satisfaction from clinician communication. Non-participant observations enabled us to map the sequence of communication opportunities in the clinical interaction, and in-depth interviews were used to identify patient perceptions of the content and clarity of clinician communication in a clinic for patients of glaucoma, a chronic eye disease. A 60-item instrument was administered to 550 participants in the quantitative phase to explore associations between patient expectations, experience and ratings of clinician communication and satisfaction with it.
