Face recognition performance with a bioptic telescopic device

ABSTRACT

To determine to what extent performance in face recognition can be improved using a bioptic device. 15 patients with central visual loss were recruited for the study. Their age ranged from 16 to 75 years. Distance visual acuity ranged between 6/24 to 6/120. perceived disability in face recognition was assessed by a four-item questionnaire. These tasks were repeated with the patients using a bioptic telescope. visual acuity improved in all patients with the use of the bioptic telescope. Mean visual acuity improved from 6/36 to 6/12. Face recognition performance improved in 80% of patients [median gain = 33%].A bioptic low vision device can offer a significant improvement in performance for face recognition and may be useful in reducing the handicap associated with this disability
