Systolic blood pressure (SBP) measurement, Schirmer tear test (STT) reading and rebound tonometry were performed.

Increasing age and the occurrence of vision impairment were not statistically associated ( P = 0.053). Retinal oedema, retinal haemorrhage and\/or retinal detachment (19 cats) and glaucoma (12 cats) were the most common findings in vision impaired cats. Increasing age was significantly associated with the occurrence of lenticular sclerosis ( P = 0.01) and attenuated retinal vessels ( P = 0.02). Increasing age and SBP were significantly associated with the occurrence of retinal detachment, haemorrhage and oedema ( P &lt;0.001 each). In cats without evidence of hypertensive ocular damage, younger cats had a tendency for higher SBP values than older cats, although this difference was not significant. Mean intraocular pressure (IOP) was 16.5 \u00b1 5.0 mmHg. Age did not significantly affect the IOP values ( P = 0.54). Mean STT was 15.8 \u00b1 4.8 mm\/min. The STT was found to increase with age ( P = 0.025).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions and relevance<\/jats:title>\n                    <jats:p>Although vision impairment is not a clinical sign of old age in cats, age-related changes may contribute to vision-threatening diseases.
