PURPOSE To present revised criteria for the diagnosis of Vogt-Koyanagi-Harada disease, a chronic, bilateral, granulomatous ocular and multisystem inflammatory condition of unknown cause. METHODS Diagnostic criteria and nomenclature were subjects of discussion at the First International Workshop on Vogt-Koyanagi-Harada Disease on October 19-21, 1999, at(More)
We recently identified a trinucleotide repeat polymorphism, (GCT)n, within the transmembrane (TM) segment of the human MHC class I MICA gene (MHC class I chain-related gene A). Five distinct alleles (A4, A5, A5.1, A6, A9) corresponding to 4, 5, 5 with one nucleotide insertion, 6 and 9 repetitions, respectively, have been detected in various HLA-homozygous B(More)
AIMS AND BACKGROUND The main objective of this study was to determine the causes of uveitis at a referral center in Riyadh, Saudi Arabia. METHODS We carried out a retrospective review of clinical records of 200 uveitis cases referred to The Eye Center, a referral center in Riyadh, Saudi Arabia. There were 120 (60%) males and 80 (40%) females with an age(More)
PURPOSE Trachoma, a chronic follicular conjunctivitis caused by infection with Chlamydia trachomatis, is the leading cause of preventable blindness. The blinding complications are associated with progressive conjunctival scarring that may result from immunologically mediated responses. We studied the processes involved in the regulation of inflammation and(More)
PURPOSE To present a case of ligneous conjunctivitis where the recurrence of membranous conjunctivitis was prevented by subconjunctival and topical instillation of fresh frozen plasma. DESIGN Interventional case report. METHODS A case of ligneous conjunctivitis with multiple recurrences since the age of 3 years developed recurrent membranous(More)
PURPOSE To determine the new corneal effective index of refraction (rN) following LASIK to be used for accurate keratometry reading (K-reading). METHODS A total of 332 eyes that underwent myopic LASIK were divided into two groups (group A [n = 137] and group B [n = 1951). In each group, patients were divided into four subgroups according to the amount of(More)
AIMS To report the clinical findings and visual outcome of patients with extended wear contact lens (EWCL) related bacterial keratitis. METHODS 11 cases with EWCL related bacterial keratitis were included. Corneal scrapings were obtained for cytology and cultures. RESULTS Nine patients had unilateral bacterial keratitis and two patients showed bilateral(More)
PURPOSE To assess the validity and accuracy of a proposed formula for keratometry (K) readings after laser in situ keratomileusis (LASIK). SETTING The Eye Center and the Eye Foundation for Research, Riyadh, Saudi Arabia. METHOD This studied comprised 34 eyes that had LASIK surgery. Refraction and an automated K-reading (auto-K) were performed(More)
