Vision‐related complaints are among the earliest symptoms in dementia. Examination of the eye has anatomical advantages over the brain because of its transparent ocular media and direct retinal neuronal connections with the brain.
Recently Drs Lily Chang, Joanna Black and Monica Acosta published a paper on choroidal thinning and ocular electrophysiology in a case of vascular cognitive impairment after stroke.
From a routine eye examination in our clinic, an 89 year old patient was recruited for a research project on retinal function in elderly and dementia patients. Using a range of vision tests including assessments of functional vision and imaging of the eye, deficits were found in outer retinal function and thinning of the choroid in this case of vascular cognitive impairment.
