Corneal biomechanical parameters and intraocular pressure: the effect of topical anesthesia
BACKGROUND The intraocular pressures and biomechanical parameters measured by the ocular response analyzer make the analyzer a useful tool for the diagnosis and management of anterior segment disease. This observational study was designed to investigate the effect of topical anesthesia on the parameters measured by the ocular response analyzer: corneal hysteresis, corneal resistance factor, Gol...
متن کاملInfluence of topical anesthesia on tonometric values of intraocular pressure.
The air pulse noncontact tonometer provides a safe and reliable method for measuring intraocular pressure (IOP), and makes it possible to avoid topical anesthesia. Based on previous reports that suggested possible anesthetic-induced IOP variations, this study was undertaken to investigate with this procedure the influence of local anesthetics on IOP and of some topically used drugs that could m...
متن کاملEffect of topical atenolol on intraocular pressure.
Placebo and topical atenolol (Tenormin), a selective beta1-adrenergic blocking substance with no intrinsic sympathomimetic or membrane-stabilising properties, were tested in 16 patients with ocular hypertension in a double-blind cross-over trial. Three different concentrations of atenolol (1, 2, and 4%) were investigated. After a single instillation there was a statistically significant fall in...
متن کاملClinical investigation of the effect of topical anesthesia on intraocular pressure
BACKGROUND/AIMS Contact tonometry is generally considered more accurate than non-contact tonometry in the assessment of intraocular pressure (IOP). This study was designed to investigate the effect of ocular anesthesia, a pre-requisite for contact tonometry, on the IOP in a sample of visually normal subjects. METHOD In a random sample of 120 young visually normal subjects (divided equally amo...
متن کاملEffect of 24-hour corneal biomechanical changes on intraocular pressure measurement.
PURPOSE To study 24-hour changes of corneal biomechanical properties and their influences on measurement of intraocular pressure (IOP). METHODS Fifteen healthy young volunteers (age range, 20-25 years) were housed for 1 day in a sleep laboratory. Sitting and supine central corneal thickness (CCT) were measured every 2 hours with an ultrasonic pachymeter. Sitting IOP and corneal hysteresis, an...
