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...

PURPOSE To evaluate the reproducibility of intraocular pressure (IOP) peaks and fluctuations detected during the water-drinking test (WDT) in patients with exfoliation syndrome (XFS) and exfoliative glaucoma (XFG). METHODS This prospective study included 34 XFS and 30 XFG patients. Each patient was evaluated twice, with the two WDTs performed on a 30-day interval. We recorded IOP peak (highes...

purpose: to evaluated the correlation between intracranial pressure (icp) and intraocular pressure (iop). methods: this interventional case series included 90 patients undergoing lumbar puncture (lp) for neurologist evaluation. iop was measured before and 1 hour after the lp by using goldmann tono-meter. patients were compared into two groups: patients with normal icp (<20 cmh2o) and patients w...

Editor’s key points † Several factors that influence intracranial pressure (ICP) also influence intraocular pressure (IOP). † Injections into the epidural space can cause cerebrospinal fluid shifts into the cranial space. † This has the potential to increase ICP and IOP. † The authors studied the effect of cervical epidural injections (14 ml) on IOP. Background. Cervical epidural injection (CEI...

Glaucoma patients who appear to be stable based on daytime in-clinic intraocular pressure (IOP) measurements may not be fully controlled over each 24-hour period. Given that there is sufficient evidence that IOP fluctuation may impact progression, the aim of management of glaucoma thus, is to achieve a target IOP with minimal diurnal fluctuation.

OBJECTIVE To determine the frequency of raised intraocular pressure (IOP) after Nd: YAG laser posterior capsulotomy and its association with the energy used with raised versus normal intraocular pressure in pseudophakes. STUDY DESIGN Comparative, cross-sectional study. PLACE AND DURATION OF STUDY Ophthalmology Department, PNS Shifa Hospital, Karachi, from August 2008 to February 2009. MET...

PURPOSE To distinguish 24-hour (circadian) and postural effects on intraocular pressure (IOP) in healthy young adults. METHODS Thirty-three volunteers were housed in a sleep laboratory for 1 day under a strictly controlled 16-hour light and 8-hour dark environment. Sleep was encouraged in the dark period. Intraocular pressure was measured in each eye every 2 hours using a pneumatonometer. Res...

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...

The effect on intraocular pressure (IOP) from dogs pulling against a collar or a harness was evaluated in 51 eyes of 26 dogs. The force each dog generated while pulling against a collar or a harness was measured. Intraocular pressure measurements were obtained during application of corresponding pressures via collars or harnesses. Intraocular pressure increased significantly from baseline when ...
