affects less than 200,000 people in the US population.

About prevalence and incidence statistics:
The term 'prevalence' of Cat Eye Syndrome usually refers to the estimated population
of people who are managing Cat Eye Syndrome at any given time.
The term 'incidence' of Cat Eye Syndrome refers to the annual diagnosis rate,
or the number of new cases of Cat Eye Syndrome diagnosed each year.
Hence, these two statistics types can differ:
a short-lived disease like flu can have high annual incidence but low prevalence,
but a life-long disease like diabetes has a low annual incidence but high prevalence.
