PURPOSE Different conclusions have been reached in recent studies concerning the immune response or tolerance of transgenic (Tg) mice expressing foreign antigens under control of retinal antigen promoters. The present study was aimed at analyzing the state of tolerance in Tg mice expressing hen egg lysozyme (HEL) under control of the rhodopsin promoter. (More)
PURPOSE To examine the hypothesis that RPE65, a protein specific to the retinal pigment epithelium, is uveitogenic in rats. METHODS Rats of four inbred strains (Lewis, Brown Norway, Fischer, and SHR) were immunized with native or recombinant bovine RPE65, or with S-antigen (S-Ag), emulsified with complete Freund adjuvant, and treated simultaneously with(More)
PURPOSE To investigate the advantages of ultrawide-field fluorescein angiography (FA) over the standard fundus examination in the evaluation of diabetic retinopathy (DR). METHODS Ultrawide-field FAs were obtained in 118 eyes of 59 diabetic patients; 11 eyes with no DR, 71 eyes with nonproliferative diabetic retinopathy (NPDR), and 36 eyes with(More)
PURPOSE We evaluated macular ganglion cell-inner plexiform layer (GC-IPL) thickness using spectral-domain optical coherence tomography (SD-OCT) in patients with chronic exposure to hydroxychloroquine (HCQ). METHODS This study included 130 subjects, who were divided into three groups: Group 1A, 55 patients with HCQ use ≥5 years; Group 1B, 46 patients with(More)
Clinical features and prognosis of HLA-B27 positive anterior uveitis (AU) were assessed compared with HLA-B27 negative AU in a Korean population, based on the medical records of AU patients seen at a university hospital. Twenty-seven HLA-B27 negative, idiopathic AU patients (group I) and 55 HLA-B27 positive AU patients (group II) were studied. HLA-B27(More)
PURPOSE This study aimed to evaluate an association between hypertension and macular thickness. METHODS A total of 827 Korean adults composed of 163 pairs of twins and their family members were included in this population-based cross-sectional study. Macular thickness was measured with optical coherence tomography at nine macular subfields defined by the(More)
PURPOSE To estimate genetic influences accounting for macular thickness in the Korean population. METHODS Study subjects were 830 healthy Korean adults (117 monozygotic twin pairs and 523 family members) from the Healthy Twin study. Macular thickness was measured with optical coherence tomography for nine subfields including the fovea, four inner(More)
1 PURPOSE. To examine the hypothesis that RPE65, a protein specific to the retinal pigment epithelium, is uveitogenic in rats. METHODS. Rats of four inbred strains (Lewis, Brown Norway, Fischer, and SHR) were immunized with native or recombinant bovine RPE65, or with S-antigen (SAg), emulsified with complete Freund adjuvant, and treated simultaneously with(More)
