Pilocarpine has been used since 1877 in the treatment of glaucoma because of its effect in lowering intraocular pressure. How­ ever, it is only since the advent of tonography and anterior chamber perfusion tech­ niques that the mechanism of this effect has been investigated. It was the purpose of this study to evalu­ ate further the effects of pilocarpine by means of diurnal tonometric and tono...

BACKGROUND To compare the effects of 2 dosing regimens of brimonidine tartrate 0.2% on diurnal intraocular pressure (IOP) and systemic hemodynamics in patients with normal-tension glaucoma (NTG). METHODS Twenty NTG patients were enrolled and randomized to receive either brimonidine twice daily (BID) for 4 weeks followed by brimonidine 3 times daily (TID) for another 4 weeks, or in reverse ord...

introduction: the term glaucoma refers to a group of diseases that have a characteristic optic neuropathy with associated visual field loss in common. intraocular pressure has been considered to be the only causal factor for glaucoma and the only factor that can be manipulated to alter the course of the disease. but considering high intraocular pressure as the only factor responsible for glauco...

PURPOSE To describe the diurnal variation of the ocular perfusion pressure (OPP) in normal, suspects and glaucoma patients. MATERIALS AND METHODS Seventy-nine subjects were enrolled in a prospective study. The diurnal curve of intraocular pressure (IOP) was performed and blood pressure measurements were obtained. Each participant was grouped into one of the following based upon the clinical e...

purpose: to compare intraocular pressure (iop) readings measured by the ocular response analyzer (ora) with those measured by the goldmann applanation tonometer (gat) in keratoconic eyes following penetrating keratoplasty (pkp) and to evaluate the influence of anatomical and biomechanical properties of the grafts on iop measurements. methods: this cross-sectional study was conducted on 45 kerat...

purpose: to study the pattern of perfusion of central retinal artery (cra) after 0.1 ml intravitreal injection of bevacizumab to verify the need for any maneuver to decrease the intraocular pressure (iop) including anterior chamber paracentesis (acp) methods: this is a prospective, interventional, noncomparative case series. patients receiving intravitreal injection of bevacizumab for choroidal...

purpose: to evaluate the effect of phacoemulsification and posterior chamber intraocular lens (pciol) implantation on intraocular pressure (iop) in eyes with chronic angle-closure glaucoma. methods: twenty-two patients with chronic angle-closure glaucoma (cacg) and visually significant cataract were included in our study. all were underwent phacoemulsification and pciol implantation. iop, depth...
