We aim to prepare, maintain and promote access to systematic reviews of all the interventions used to prevent
or treat eye diseases and/or visual impairment. We also consider the evidence for interventions that aim to help people adjust to visual impairment or blindness. We have a strategy for prioritisation that emphasises major causes of blindness in the world and areas where there are wide variations in clinical practice and outcomes.
Our reviews focus on randomised or quasi-randomised controlled trials and provide descriptive syntheses where such data are lacking.
The main outcome for our reviews is visual function, which can be assessed in a variety of ways including measurement of visual acuity, assessment of visual field, and assessment of vision related quality of life. Other outcomes are included as necessary within individual reviews.
