  1. 1. Intraocular pressure : clinical aspects and new measurement methods

    Författare :Gauti Jóhannesson; Christina Lindén; Per Hallberg; Anders Eklund; Boel Bengtsson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Intraocular pressure; glaucoma; tonometry; ISO; LASEK; CCT; curvature; Ophtalmiatrics; Oftalmiatrik; Ophtalmology; oftalmiatrik;

    Sammanfattning : Intraocular pressure (IOP) measurement is a routine procedure and a fundament in glaucoma care. Elevated IOP is the main risk factor for glaucoma, and to date, reduction of IOP is the only possible treatment. In a retrospective clinical material, the prevalence of open angle glaucoma was estimated on the west coast of Iceland. LÄS MER

  3. 2. Intraocular Microdialysis

    Författare :Janina Waga; Lund Oftalmologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ophtalmology; pharmacokinetics; drug adminstration; vitreous body; Microdialysis; eye; Oftalmologi;

    Sammanfattning : The method of microdialysis has been adapted for ocular use. It is a technique for monitoring concentrations of different molecules in a tissue in vivo. It is based on the principle of diffusion through a semipermeable membrane. The membrane is mounted on a soft plastic shaft, connected to an inlet and an outlet tube. LÄS MER

  4. 3. Applanation Resonance Tonometry for Intraocular Pressure Measurement

    Författare :Per Hallberg; Olof A. Lindahl; Anders Eklund; Christina Lindén; Per Ask; Umeå universitet; []
    Nyckelord :Physics; Resonance; applanation; tonometry; glaucoma; Goldmann; biomechanical; Intraocular; ART; Fysik; fysik; Physics;

    Sammanfattning : Elevated intraocular pressure (IOP) is one of the major risk factors for glaucoma. Since glaucoma is a leading cause of blindness, reliable methods for measuring the IOP are important. This doctoral dissertation presents a new method, applanation resonance tonometry (ART), for measurement of IOP. LÄS MER

  5. 4. Resonator sensor technique for medical use : an intraocular pressure measurement system

    Författare :Anders Eklund; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sensor; Vibration; Hardness; Prostate; intraocular pressure; resonator; eye; applanation; glaucoma;

    Sammanfattning : In the work of this doctoral dissertation a new resonator sensor technique, first presented in 1989, has been further developed and evaluated with focus on technical characteristics and applications within the medical field. In a first part a catheter-type tactile sensor using the resonator sensor technique was evaluated in a silicone model and applied to human prostate in vitro. LÄS MER

  7. 5. On posterior capsule opacification

    Författare :Karin Sundelin; Göteborgs universitet; []
    Nyckelord :posterior capsule opacification; quantification; capsulotomy; benefit; intraocular; lens; optic design; Catquest; Evaluation of Posterior Capsule Opacification;

    Sammanfattning : AimsPosterior capsule opacification (PCO) is the most common complication after cataractsurgery. The aim of this study was to increase our knowledge about PCO regardingquantification, treatment effects and how different designs of intraocular lenses(IOLs) influence occurrence. LÄS MER
