Case Series of Posterior Cortical Atrophy (.pdf)

Posterior cortical atrophy (PCA), a visual variant of Alzheimer's disease, is an increasingly prevalent disease with today's aging population. Distinguishing between PCA and other causes of visual impairment is essential in the early diagnosis and treatment. Clinical presentation is heralded by subjective vision loss, yet a normal ophthalmic examination - there is not yet definitive diagnostic criteria and it may be underdiagnosed. Through the advances in understanding the early signs and symptoms of this disease, the prospect of early diagnosis, and thus eventually, prevention and treatment is optimistically hopeful.
