Autoregulation of the retinal circulation in response to an acute elevation of intraocular pressure was investigated in 17 subjects (23 eyes) with no ocular abnormalities, by means of the blue field entoptic phenomenon. This phenomenon allows a person to observe leukocytes flowing in his own macular capillaries. Subjects were instructed to compare the speed of their leukocytes in one eye with t...

The aim of this study was to determine intraocular pressure (IOP) and central corneal thickness (CCT) measurements in healthy rabbits establish clinical reference values investigate the possible relationship between these measurements. included 40 eyes 20 New Zealand albino rabbits, aged 1.5-2 years. All were with no abnormalities, disease, or evidence glaucoma. An ultrasonographic pachymeter u...

To assess whether the intraocular pressure (IOP) in selective laser trabeculoplasty (SLT)-treated eyes is maintained following subsequent phacoemulsification and lens implant (phaco + IOL). Retrospective single center review of 45 eyes of 35 patients who had open angle glaucoma (OAG), successfully treated by SLT by the same surgeon (EA), and then had routine phaco + IOL by same surgeon (EA). Th...

PURPOSE In living cynomolgus monkey eyes, the authors compared manometrically set and measured intraocular pressure (IOP) with simultaneous IOP readings obtained with the Tono-Pen (TP), a handheld applanation tonometer based on the Mackay-Marg principle. METHODS In three pentobarbital-anesthetized cynomolgus monkeys, IOP was set and measured manometrically after anterior chamber cannulation t...

To study the possible physiological role of atrial natriuretic peptide (ANP) in the regulation of intraocular pressure (IOP) the effects of an increase of endogenous ANP within the physiological range induced by the neutral endopeptidase 24.11 (NEP) inhibitor candoxatril were examined. In a single masked placebo controlled trial, seven patients were studied with normal IOP (six male, one female...

AIMS Central retinal vein pulsation is affected by intracranial pressure (ICP), glaucoma and venous pathology. Its genesis is poorly understood with most models suggesting that intraocular pressure (IOP) fluctuation dominates the rhythm of venous pulsation; however, this has not been explored experimentally. This study planned to measure the timing of central retinal vein pulsation with respect...

Although a large proportion of anterior uveitis is noninfectious, viruses are regarded as an important cause infectious uveitis. Herpes common causes hypertensive PCR analysis aqueous sample collected at the slit lamp under aseptic conditions for viral DNA commonly used technique to confirm diagnosis during acute phase. Anterior may be shortened by prompt use therapeutic doses antiviral therapy...

Purpose: To describe the methods of performing water drinking test (WDT) and its applications in glaucoma management.
 Methods: This review is based on pertinent publications retrieved by a selective search PubMed, supplemented further articles chosen authors.
 Results: Intraocular pressure (IOP) changes throughout day. IOP peak has been identified as risk factor onset progression. WD...

background: to evaluate the agreement in intraocular pressure (iop) measurements by ocular response analyzer (ora) and tono-pen xl (txl) with the goldmann applanation tonometer (gat) and to examine corneal biomechanical properties in aphakic glaucoma patients with a central corneal thickness (cct) >600 µ. methods: thirty-six eyes of aphakic glaucoma patients (group 1) and 40 eyes of normal chil...
