Patterns of Uveitis in a University-based Tertiary Referral Center in Riyadh, Saudi Arabia

Abstract

The most common anatomic diagnosis was panuveitis. VKH disease, PTU, BD, and toxoplasmosis are the most frequently diagnosed entities.

Differential CXC and CX3C Chemokine Expression Profiles in Aqueous Humor of Patients With Specific Endogenous Uveitic Entities

“…Diagnoses were made using established clinical criteria, with supporting laboratory evidence as needed. 7,8 HLA-B27-associated uveitis was diagnosed based on HLA typing of peripheral blood cells and typical ocular manifestations of unilateral acute anterior uveitis. In each patient, the uveitis activity was graded according to the criteria of the Standardization of the Uveitis Nomenclature Working group grading scheme.…”

Ocular Tuberculosis

“…In a prospective case series in Japan, 20.6% of 126 patients with uveitis had a positive TST, and 7.9% were felt to have intraocular tuberculosis (14). As previously noted, in Saudi Arabia, tuberculosis was stated to be the cause in 17.8% of uveitis cases seen in a major referral center (15). …”

“…In a prospective case series in Japan, 20.6% of 126 patients with uveitis had a positive tuberculosis skin test, and 7.9% were believed to have intraocular tuberculosis (14). In Saudi Arabia, tuberculosis was thought to be the cause in 17.8% of cases of uveitis seen at a university-based tertiary referral center (15). In patients presenting with uveitis in Boston between 1982 and 1992, tuberculosis caused this disease in 0.6% of cases (16).…”

Design and Interpretation of Clinic-Based Studies in Uveitis

“…contains ten original, retrospective, clinic-based surveys reporting on various aspects of the demographic and clinical features of uveitis subjects seen in tertiary referral clinics in Chile, 1 Germany, 2 India, 3 Iran, 4 Japan, 5 Lebanon, 6 Saudi Arabia, 7 Singapore, 8 Thailand, 9 and Turkey. 10 Such retrospective studies of less common conditions like uveitis are valuable in that they provide important information that otherwise would be difficult to obtain using more robust, prospective epidemiologic methodologies -including data regarding regional differences and changes in patterns and prevalence of uveitis over time.…”
