| Annotation | The types of visual impairment following stroke are wide-ranging and encompass low vision, eye movement and visual field subnormalities, and visual perceptual difficulties. This paper presents a 1-year data set, and identifies the type of visual impairment occurring following stroke and their prevalence. A multi-centre prospective observation study was undertaken in 14 acute trust hospitals. Stroke survivors with a suspected visual difficulty were recruited. Standardised screening or referral and investigation forms were employed to document data on visual impairment, specifically assessment of visual acuity, ocular pathology, eye alignment and movement, visual perception (including inattention), and visual field defects. 323 patients were recruited (mean age 69). 68% had eye alignment / movement impairment. 49% had visual field impairment, 26.5% had low vision and 20.5% had perceptual difficulties. Of patients referred with a suspected visual difficulty, only 8% had normal vision status confirmed on examination. 92% had visual impairments of some form confirmed, which is considerably higher than previous publications and probably related to the prospective, standardised investigation offered by specialist orthoptists. However, under-ascertainment of visual problems cannot be ruled out. Supplementary data are available on the Age and Ageing website. (RH). |
