Aqueous outflow via the conventional outflow pathway is dependent on the pressure gradient between intraocular pressure (IOP) and episcleral venous pressure (EVP). Elevated IOP resulting from increased EVP is a well-known complication of arteriovenous fistulas, which are usually between the carotid artery and the cavernous sinus. Arteriovenous malformations usually occur spontaneously, after a ...

The purpose of this study was to evaluate the effects of a combination of latanoprost and pilocarpine onthe intraocular pressure in experimentally glaucomatous rabbits. Ocular hypertension was induced in 11conscious rabbits by the oral administration of tap water (70 mL/kg) via an orogastric tube. The study wasconducted in three therapeutic groups to test the effects of latanoprost (group L), p...

BACKGROUND We report on a patient with unilateral elevation of intraocular pressure during hemodialysis. CASE A 60-year-old man with unilateral exfoliative material complained of severe pain in the right eye during hemodialysis. OBSERVATIONS The intraocular pressure (IOP) in the patient's right eye was 56 mm Hg, and increased repeatedly during hemodialysis. The IOP in his left eye remained ...

It is known that marijuana smoking and administration of natural cannabinoids reduce intraocular pressure. However, it has not been established whether the intraocular pressure-lowering effects of cannabinoids are mediated by cannabinoid receptors. Aminoalkylindoles are a new class of cannabimimetics with structures entirely different from those of natural cannabinoids. WIN55212-2, a prototypic...

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...

Purpose The diurnal cycling of intraocular pressure (IOP) was first described in humans more than a century ago. This cycling is preserved in other species. The physiologic underpinning of this diurnal variation in IOP remains a mystery, even though elevated pressure is indicated in most forms of glaucoma, a common cause of blindness. Once identified, the system that underlies diurnal variation...

this prospective study evaluated the long-term results of intraoperative 5-fu in glaucoma patients undergoing trabeculectomy. 14 patients categorized as high risk or medium risk underwent trabeculectomy with 5-fu and were followed for a mean period of 32 months. patients were evaluated for visual acuity, cup-disc ratio and intraocular pressure (iop); the number of medications was also taken int...

background: increase in intraocular pressure (iop) following tracheal intubation during general anesthesia can be troublesome. we compared the influence of two muscle relaxants, cisatracurium and atracurium, on iop in patients undergoing general anesthesia. methods: this randomized, double-blind, comparative trial was conducted on 90 candidates for elective non-ophthalmic surgery under general ...

BACKGROUND Prevention of rise in intraocular pressure (IOP) is essential in patients undergoing surgery for perforated eye injuries. Metoclopramide, a prokinetic agent, is commonly used to hasten gastric emptying in emergency surgeries. AIM To study the change in IOP after intravenous metoclopramide and to study the influence of metoclopramide on change in IOP after succinylcholine and trache...

Background: During the administration of general anaesthesia, laryngoscopy and endotracheal intubation must be performed. Just before intubation, succinyl choline is given. Intraocular pressure, heart rate, blood pressure may all rise as a result this. Many medications have been tried utilised to mitigate this stress reaction. Dexmedetomidine sedative, anxiolytic, analgesic since it an alpha2 a...
