The Science behind the Tip

Self-reported visual disability in glaucoma which correlates with level of visual field loss includes bumping into things, difficulty with stairs, tripping and problems with outdoor mobility tasks (1,2,3,4). However, the question ‘Do you ever notice that parts of your field of vision are missing’ has no relationship with the level of binocular visual field loss (2).

An example of why this knowledge is important for doctors, patients and policymakers is given by the International Glaucoma Society in its ‘Driving and Glaucoma’ information leaflet (5): ‘The gradual onset and adaption to the loss of vision means there is no awareness of these blind areas but there are potential serious consequences when driving.‘
