Overview
Epidemiology and Demographics
Prevalence
Worldwide, the prevalence of uveitis ranges from a low of 69 per 100,000 persons to a high of 204 per 100,000 persons with an average prevalence of 115 per 100,000.
Prevalence by Subtype
Several studies have reported prevalence data among a large group of uveitis patients, as follows: By Anatomy
- 52-90% have anterior uveitis
- 5-21% have posterior uveitis
- 1-16% have panuveitis
- 1-12% have intermediate uveitis
By clinical features
- 58% had chronic uveitis
- 78% had non-granulomatous inflammation
- 83% had a non-infectious etiology
Incidence
Worldwide, the incidence of uveitis ranges from 17 to 52 per 100,000 per year.
Age
The mean age of diagnosis of uveitis is 37 years. The prevalence varies greatly depending on the underlying etiology. The following is an example of age distribution by underlying etiology: Children: juvenile rheumatoid arthritis, toxocariasis. Young adults: Behçet's disease, human leukocyte-associated antigen B27-associated uveitis, Fuch's uveitis. Older adults: Vogt-Koyanagi-Harada (VKH) syndrome, herpes zoster ophthalmicus and, in the developing world, tuberculosis and leprosy.
