Background. Blood pulsation affects the results obtained using various medical devices in many different ways. Method. The paper proves the effect of blood pulsation on intraocular pressure measurements. Six measurements for each of the 10 healthy subjects were performed in various phases of blood pulsation. A total of 8400 corneal deformation images were recorded. The results of intraocular pr...

PURPOSE The lamina cribrosa, as the main structural element of the optic nerve head, forms a pressure barrier between the intraocular space and the retrobulbar space. The function as a pressure barrier may have importance for the pathogenesis of ocular diseases related to intraocular pressure and/or cerebrospinal fluid (CSF) pressure, such as the glaucomas. The purpose of the present study was ...

OBJECTIVE To compare the short-term and long-term efficacy of using releasable sutures vs conventional interrupted sutures for scleral flap suturing in trabeculectomy. DESIGN A prospective randomized study. SETTING A university-affiliated referral eye hospital. PATIENTS Thirty consecutive patients requiring trabeculectomy for uncontrolled primary glaucoma. INTERVENTION Fifteen patients ...

AIM To determine whether fetal and infant growth, as assessed by weight at birth and weight at 1 year, are related to intraocular pressure. METHODS 717 men and women born in Hertfordshire between 1920 and 1930, for whom records of birth weight and weight at 1 year were available, were examined. Visual fields were assessed using the Takagi central 25 degrees 75 point static threshold screening...

purpose: to evaluate the early and intermediate outcomes of ahmed glaucoma valve implantation in pediatric glaucoma at labbafinejad medical center. methods: this was a retrospective chart review of 101 eyes of 80 consecutive patients with pediatric glaucoma who underwent ahmed glaucoma valve implantation. success was defined as an intraocular pressure less than 21 mmhg with or without medicatio...

OBJECTIVE To evaluate the efficacy of preoperative oral clonidine (5 g/kg) in preventing ocular hypertension in the early period after cataract surgery with posterior chamber intraocular lens implantation under general anaesthesia. METHODS This was a randomized double-blind clinical trial comprising of 62 eyes in 62 patients with senile cataract without using any viscoelastics. They were rand...

PURPOSE To correlate the ibopamine provocative test with the diurnal tension curve (highest intraocular pressure-IOP and range) in glaucoma. METHODS This is a prospective case series including glaucoma patients from the Federal University of Goiás, Glaucoma Service. Two 2% ibopamine eyedrops were instilled into one or both eyes of each patient, 5 minutes apart. Intraocular pressure was checke...

To test whether there is a relationship between handedness and the intraocular pressure and there is a lateralization in the intraocular pressure, the intraocular pressures of the right- and left-eyes were compared in right- and left-handed students. The intraocular pressures were higher in the right-eye than in the left-eye in men, right-handers, and right-eyed subjects; there was no right-lef...

A number of hormones are known to affect intraocular pressure. Of these, the female sex hormones are the predominant ones to cause variations in intraocular pressure. The aim of this study was to determine if variation in sex hormones in pregnancy affects intraocular pressure. This study was a longitudinal one. 117 pregnant women aged 20 to 35 years in their first trimester of pregnancy were fo...

Intraocular pressure, a major modifiable risk factor for glaucoma, has been shown to fluctuate throughout the day in patients with glaucoma. The detection and measurement of this fluctuation may help guide the clinical management of glaucomatous individuals. The Sensimed Triggerfish contact lens sensor (CLS), which has recently gained approval for marketing in the USA, is designed to detect int...
