purpose: to evaluate the effects of diurnal fasting during ramadan on intraocular pressure (iop) in healthy subjects. methods: the study was conducted on healthy male volunteer less than 40 years of age without ocular or systemic diseases who were on religious fasting during ramadan, 2004. intraocular pressure were measured at 9 am and 1, 5, and 7 pm in 2nd and 4th weeks of ramadan and also one...

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 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...

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 evaluate the influence of anatomical and biomechanical properties of the grafts on the iop measurements methods : in this cross-sectional study conducted on 45 kera...

We report the results of repeated ambulatory continuous 24-hour intraocular pressure (IOP) monitoring with a contact lens sensor (CLS) in a glaucoma patient with ocular pain after ab interno trabeculotomy (Trabectome™) surgery. Our findings show that a combined prostaglandin-pilocarpine treatment reduced nighttime IOP peaks and relieved the patient's symptoms.

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...

AIM To evaluate the morphology of the optic nerve head in eyes with pigmentary glaucoma. METHODS Colour stereo optic disc photographs of 62 patients with pigmentary glaucoma and 566 patients with primary open angle glaucoma were morphometrically evaluated. By prestudy selection, mean visual field defect and neuroretinal rim area were not significantly different between the two groups (p = 0.8...

Elevated intraocular pressure may lead to retinal ganglion cell injury and consequent visual deficits. Chronic intraocular pressure increase is a major risk factor for glaucoma, a leading blinding disease, and permanent visual deficits can also occur following acute pressure increments due to trauma, acute glaucoma or refractive surgery. How pressure affects retinal neurons is not firmly establ...
