PURPOSE: To investigate the role of TANK-binding kinase 1 (TBK1) gene copy-number variations (ie, gene duplications and triplications) in the pathophysiology of various open-angle glaucomas. METHODS: In previous studies, we discovered that copy-number variations in the TBK1 gene are associated with normal-tension glaucoma. Here, we investigated the prevalence of copy-number variations in cohorts of patients with other open-angle glaucomas-juvenile-onset open-angle glaucoma (n=30), pigmentary glaucoma (n=209), exfoliation glaucoma (n=225), and steroid-induced glaucoma (n=79)-using a quantitative polymerase chain reaction assay...

Jason S Slakter, Jeffrey W Schneebaum, Sabah A Shah
PURPOSE: To develop a new diabetic retinopathy severity scoring system and to determine if it can monitor changes from baseline as well as identify precise features that have changed over time. Such a grading system could potentially provide an understanding of the impact of treatments utilizing an algorithmic scoring technique. METHODS: The traditional ETDRS grading system was examined and a flow algorithm based on the grading approach was created. All visual comparative assessment points, relying on identification of features in relation to prior standard photographic images, were evaluated and quantified...

PURPOSE: To test the hypothesis that the accumulation of oxidized phospholipids (OxPL) in the macula is toxic to the retina unless neutralized by a variety of mechanisms, including binding by lipoprotein(a) [Lp(a)], which is composed of apolipoprotein(a) [apo(a)] and apolipoprotein B-100 (apoB). METHODS: Human maculas and eyes from two Lp(a) transgenic murine models were subjected to morphologic, ultrastructural, and immunohistochemical analysis. "Wild-type Lp(a)" mice, which express human apoB-100 and apo(a) that contains oxidized phospholipid, and "mutant LBS(-) Lp(a)" mice with a defective apo(a) lysine binding site (LBS) for oxidized phospholipid binding, were fed a chow or high-fat diet for 2 to 12 months...
