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

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

   Abstract : 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. READ MORE

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

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

   Abstract : 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. READ MORE

5. 3. Applanation Resonance Tonometry for Intraocular Pressure Measurement

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

   Abstract : 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. READ MORE

6. 4. Long-term follow-up of pseudoexfoliation, intraocular pressure and glaucoma : epidemiological studies in northern Sweden

   Author : Siv Åström; Christina Lindén; Hans Stenlund; Bertil Lindblom; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pseudoexfoliation; glaucoma; intraocular pressure; age cohort; screening; long-term follow-up;

   Abstract : Purpose An age-cohort was studied with long-term follow-up. The population was born in 1915, living in the municipality of Skellefteå in 1981. The purpose was to investigate the prevalence and incidence of pseudoexfoliation (PEX), its influence on intraocular pressure (IOP) and development of open-angle glaucoma (OAG). READ MORE

7. 5. Fluid dynamic principles for analysis of intracranial pressure control : application towards space medicine and hydrocephalus

   Author : Petter Holmlund; Anders Eklund; Sara Qvarlander; Jan Malm; Marek Czosnyka; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Intracranial pressure; posture; cerebrospinal fluid; microgravity; venous collapse; internal jugular vein; fluid dynamics; venous pressure; spaceflight-associated neuro-ocular syndrome; hydrocephalus; mathematical modeling; ultrasound; magnetic resonance imaging;

   Abstract : Intracranial pressure (ICP) is an important component of the fluid dynamic environment of the brain and plays a central role with regards to the maintenance of normal cerebral blood flow and neuronal function. However, many regulatory mechanisms controlling the ICP are still poorly understood. READ MORE
