Patterns of Uveitis in a Tertiary Care Referral Institute in Saudi Arabia

Purpose: To present the pattern, causes and complications of uveitis in one of the tertiary eye centers in Saudi Arabia.Methods: In this retrospective study, clinical records of randomly selected cases of uveitis attending the King Khaled Eye Specialist Hospital, Saudi Arabia, from 2001 to 2010, were reviewed.Results: Our series included 888 out of 1286 cases of uveitis. Among them, there were 390 men (43.9%) with a mean age of 39.6 11 (range: 6-94 years). The prevalence of uveitis among all eye patients was 1.5% and the annual incidence was 129 cases. Uveitis was bilateral in 567 patients (63.8%), mainly anterior in 27.3%, intermediate in 12.7%, posterior in 7.1%, while 52.9% were panuveitis. Infective etiology was seen in 180 patients (20.3%), of which presumed tuberculous uveitis (PTU) was the commonest cause in 94 patients (52%), followed by herpetic in 46 (26%) and toxoplasmosis in 29 (16%). Vogt-Koyanagi-Harada (VKH) 22%, Behcet uveitis (BU) 14.6%, idiopathic anterior uveitis 12.5%, presumed tuberculous uveitis (PTU) 10.6%, and idiopathic intermediate uveitis (10.1%) accounted for the majority of cases, whereas other diagnostic entities accounted for 30%. The most common cause of anterior uveitis was idiopathic uveitis (101; 41.7%), followed by herpetic (46; 19%). Toxoplasmosis was the most frequent cause of posterior uveitis (29; 46.3%). Intermediate uveitis was most commonly idiopathic (86; 76.1%). VKH disease was the most common cause of panuveitis (195; 41.5%), followed by Behcet disease (118; 25.1%). The common complications of uveitis were glaucoma (34.1%), posterior synechiae (22.3%) and cataract (15.1%).Conclusions: The most common anatomic diagnosis was panuveitis. VKH disease and Behcet disease were the most frequent causes and glaucoma was the most common complication of uveitis.
