The incidence (rate of occurrence of new cases) and prevalence (percentage of the population that is affected) of punctate inner choroidopathy (PIC) is difficult to estimate due to the wide spectrum of signs, symptoms and severity associated with the condition. Some affected individuals may remain asymptomatic and therefore not receive a diagnosis; it is possible that only the more severely affected individuals are under medical care for the condition. One study by Brown and colleagues estimates that the national incidence (in the United States) of PIC would be approximately 100–200 cases per year. There is limited information available about the incidence and/or prevalence of PIC in other populations or worldwide.
