    Purpose Retinal oximetry is a technique based on spectrophotometry where images are analyzed with software capable of calculating vessel oxygen saturation and vessel diameter. In this study, the effect of automation of measurements of retinal vessel ...

    Ocular drug delivery is very challenging due to the anatomical and physiological barriers of the eye. Poor aqueous solubility of many drugs and short retention time at ocular surfaces makes the formulation of topical dosage forms even more challenging. ...

    Vanstarfsemi í fitukirtlum augnloka er algeng ástæða augnþurrks. Demodex-mítlar geta valdið slíkri vanstarfsemi og þar með hvarmabólgu með kláða, þurrki og almennri vanlíðan á augnsvæði. Það er mikilvægt að hafa Demodex-mítla í huga við greiningu ...

    Purpose: To examine feasibility of phase-contrast magnetic resonance imaging (PCMRI) and to assess blood flow rate in the ophthalmic artery (OA) in patients with normal tension glaucoma (NTG) compared with healthy controls. Methods: Sixteen patients ...

    Purpose: The aim of the study was to determine the perimetric rate of glaucoma progression in the ongoing Glaucoma Intensive Treatment Study (GITS) after 3 years of follow-up. Design: This is a randomized, two-centre, prospective open-labelled treatment ...

    PURPOSE. To investigate if decrease of IOP affects the volumetric blood flow rate in the ophthalmic artery (OA) in patients with previously untreated ocular hypertension. METHODS. Subjects with untreated ocular hypertension (n = 30; mean age 67 ± 8 ...

    The study objective was to delineate the genetics of inherited retinal degenerations (IRDs) in Iceland, a small nation of 364.000 and a genetic isolate. Benefits include delineating novel pathogenic genetic variants and defining genetically homogenous ...

    Purpose: We hypothesize that a collapse of the optic nerve subarachnoid space (ONSAS) in the upright posture may protect the eyes from large translamina cribrosa pressure differences (TLCPD) believed to play a role in various optic nerve diseases (e.g., ...
  • Harðarson, Sveinn Hákon; Stefánsson, Einar; Bek, Toke (2021-05-12)
    Purpose According to cross-sectional studies, oxygen saturation is elevated in retinal vessels in diabetic patients. We evaluated how retinal oxygenation (metabolic marker), vessel diameters and retinopathy grade (structural markers) change over time ...

    The corneal endothelium is vital for transparency and proper hydration of the cornea. Here, we conduct a genome-wide association study of corneal endothelial cell density (cells/mm2), coefficient of cell size variation (CV), percentage of hexagonal ...
