The prevalence of visual impairment among elderly patients admitted to
hospital is unknown. This group of patients may be particularly at ri
sk from poor vision which could jeopardise their independence. A prosp
ective study of visual impairment and its aetiology in acute geriatric
admissions assessed after the acute illness had settled was performed
. Subjects were all patients aged 65 years or over, excluding those ch
ronically confused, admitted to the Department of Geriatric Medicine a
t the Royal Liverpool University Hospital with an acute medical illnes
s. After the acute illness had settled visual impairment, as defined b
y the American criteria (best acuity 6/18), was assessed on the ward w
ith a Snellen chart read at 6 m using binocular vision and current gla
sses. Those patients identified with impaired vision on initial screen
ing were formally assessed in the ophthalmology department to identify
the cause. 200 patients were examined. 101 patients (50.5%) had impai
red vision. In these patients, correctable refractive errors were pres
ent in 40%, cataract in 37% and senile macular degeneration in 14%. Of
the 101 patients with impaired vision 79% had a reversible cause, Com
paring these results with a recent study in the community showed a muc
h higher incidence for patients admitted to hospital, There was a part
icularly high prevalence in those elderly patients who were admitted w
ith falls (76%, p = 0.0003). In conclusion, elderly patients, especial
ly those presenting with falls, admitted to hospital have a high preva
lence of visual impairment. Visual impairment may be compounding or ca
using falls. Hence, screening the elderly 'faller' admitted to hospita
l for visual impairment may be beneficial to the patient and cost-effe
ctive as many of the causes are simply reversible.
