To investigate the diurnal variation of the pulse waveform parameters determined by laser speckle flowgraphy (LSFG) on the optic nerve head (ONH) in healthy subjects.This prospective cross sectional study was conducted at Nagoya University Hospital. We studied 13 healthy volunteers whose mean age was 33.5 ± 7.6 years. Eight pulse waveform parameters on the ONH were determined by LSFG (LSFG-NAVI...

Background: Cataract surgery is one of the most common surgeries in the world, especially in elderly patients, and often performed topically with sedative agents. Ketamine is one of the most commonly used agents and the effect of different doses on intraocular pressure is in dispute. The present study investigates the effect of a low dose of ketamine on intraocular pressure in patients undergoi...

OBJECTIVES To investigate the 24 h effects of bimatoprost 0.01% monotherapy on intraocular pressure (IOP) and ocular perfusion pressure (OPP). DESIGN Prospective, open-label experimental study. SETTING Single tertiary ophthalmic clinic. PARTICIPANTS Sixteen patients with diagnosed primary open-angle glaucoma (POAG) or ocular hypertension (ages, 49-77 years). INTERVENTIONS Baseline data ...

This study evaluated the distribution of Intraocular pressure (IOP) levels in 67 normal and 59 ocular hypertensive (OHT) subjects during the day after placing control on all those factors that can affect IOP. The IOP was measured with the Goldmann applanation tonometer. All the subjects were examined according to standard protocols. Both in the normal and OHT subjects, the peak of mean IOP appe...

: This study was designed to evaluate and compare differences between Goldmann applanation tonometer’s (GAT) values non-contact (NCT) In various central corneal thickness(CCT). prospective of 100 eyes 50 subjects done for the age group 25 yrs – 75 yrs, who did not have any glaucomatous changes in optic disc. Intraocular pressure readings were taken by GAT NCT measured within a fixed time range ...

     Diurnal air temperature modeling is a beneficial experimental and mathematical approach which can be used in many fields related to Geosciences. The modeling and spatio-temporal analysis of air Diurnal Temperature Cycle (DTC) was conducted using data obtained from 105 synoptic stations in Iran during the years 2013-2014 for the first time; the key variable for controlling the cosine term i...

PURPOSE To compare the intraocular pressure (IOP) reduction by latanoprost and timolol, and to study factors of prognostic value for assessing this reduction. METHODS We analyzed 829 patients included in three phase 111 studies comparing six months' treatment with 0.005% latanoprost once daily and 0.5% timolol twice daily in patients with open-angle glaucoma or ocular hypertension. Analysis o...
