I think it's impossible to translate accurately, without knowing whether they mean "incidence" or "prevalence". You could try being vague and translate it as "frequency of uveitis occurrence" or "the number of uveitis cases".

Uveitis is the third leading cause of blindness worldwide. Despite this fact, it is a relatively rare disease. In the Unites States, uveitis has an estimated prevalence of about 38 cases per 100,000 population, and an incidence of 15 cases per 100,000
population.

Uveitis mainly occurs in the 20-50 year age group, and can affect one or both eyes. The incidence of uveitis varies from 14 to 52.4/100,000 with the overall prevalence around the world is up to 0.73%.
