Administration of timolol to one eye is associated with a decrease in intraocular pressure in both eyes. To further investigate this effect the contralateral decrease in intraocular pressure was measured in a three arm crossover study using a 0.1 mg dose of timolol given topically to an eye, a 0.1 mg dose of timolol given lingually, and a placebo given topically. Two hours after topical timolol...

OBJECTIVE To evaluate the effectiveness of trabeculectomy trabeculotomy in the reduction of intraocular pressure in patients with primary congenital glaucoma. MATERIAL AND METHODS A pre-experimental before and after study was conducted with several measurements after; patients with intraocular pressure≥21 mmHg were included, of both sexes, and children under six years, which had ​​the trabecu...

OBJECTIVE This study aimed to investigate the association between intraocular pressure and metabolic syndrome according to menopause status in nonglaucomatous Korean women. METHODS We examined the relationship between intraocular pressure and metabolic syndrome in 4,524 nonglaucomatous Korean women (2,866 premenopausal women and 1,658 postmenopausal women) who participated in the 2008 Korean ...

PURPOSE To determine whether a new cyclic GMP analog, 2'-O-(4-benzoyl)benzoylguanosine 3',5' cyclic monophosphate (BB-cGMP), significantly reduces intraocular pressure in either normotensive or hypertensive eyes of rabbits. METHODS Intraocular pressure of normal adult rabbits and/or rabbits with alpha-chymotrypsin-induced ocular hypertension was measured after topical application of BB-cGMP f...

PURPOSE To prospectively study the success rates and complications of viscocanalostomy. METHODS Prospective nonrandomized case series of 46 eyes (46 patients) with medically uncontrolled primary and secondary open angle glaucoma. All patients in the study underwent viscocanalostomy. Control of intraocular pressure was used to measure success. Pre and postoperative glaucoma medications, visual...

Hyperosmolar solutions and digital massage are frequent adjuncts employed to minimize vitreous loss at cataract extraction (Scott, i962; Virno, Cantore, Bietti, and Bucci, I963; Murray and Tipler, I966; Guyton, I954; Kirsch and Steinman, I955). The former is effective in reducing vitreous mass during the time interval usually necessary to complete a lens extraction, but the latter may not have ...

PURPOSE To assess changes in intraocular pressure (IOP) during standard coaxial or bimanual microincision phacoemulsification. SETTING Oregon Eye Center, Eugene, Oregon, USA. METHODS Bimanual microincision phacoemulsification (microphaco) was performed in 3 cadaver eyes, and standard coaxial phacoemulsification was performed in 1 cadaver eye. A pressure transducer placed in the vitreous cav...

BACKGROUND Some publications suggest a strong correlation between the intracranial pressure and the intraocular pressure. Other studies claim no correlation between these two physiologic variables. Our aim was to study whether the tonometry could be a useful method to evaluate intracranial pressure in patients with suspected intracranial abnormality. METHODS We evaluated the correlation betwe...
