%X Posterior cortical atrophy (PCA) is a neurodegenerative syndrome that is characterised by a progressive decline in visuospatial and visuospatial skills1,2. Precise estimates of the prevalence and incidence of PCA are difficult to determine; this largely owes to an under-recognition of the PCA syndrome, misdiagnosis, and certain inconsistencies in the application of clinical and research criteria for PCA. Estimates to date have been based on specialist dementia and memory clinics, which include reports of between 8-13% of patients as having predominant visual disturbances in addition to nonvisual symptoms characteristically associated with PCA, such as difficulties with writing, calculation, spelling, handwriting and praxis skills3,4.  All of this leads easily to misinterpretation of routine ophthalmological investigations using automated static perimetry, crowded Snellen letter or Ishihara colour charts.
