The relationship of the ophthalmic pulse amplitude to the intraocular pressure has been described in rabbits and dogs. The effect of a suction cup on the intraocular pressure has been investigated in rabbit eyes and human eyes. Sample pulse tracings have been obtained using a suction cup on rabbits and man. Two estimates were made of the volume changes associated with the ophthalmic pulse xoave...

Background/aims—Mechanical forces are thought to induce cellular responses through activation of signalling pathways. Cells within the intraocular environment are exposed to constant changes in the levels of intraocular pressure. In this study, an attempt was made to determine the acute eVects of elevated hydrostatic pressure on diVerent intraocular cells

OBJECTIVE Clear corneal cataract incisions without sutures allow for rapid visual rehabilitation after phacoemulsification but might be associated with an increased risk of postoperative infection. The goal of this study was to examine in vitro dynamic changes in unhealed clear corneal cataract incisions that might adversely affect the risk of intraocular infection. DESIGN Laboratory investig...

Method: Cataract surgery was performed after controlling the intraocular pressure in patients presenting with acute phacomorphic glaucoma. Intraocular lenses were inserted in the bag after conventional extracapsular cataract extraction. Patients with minimum follow up of one year were analyzed for the study. Corrected visual acuity, intraocular pressure and any complications of surgery were rec...

Increased arterial stiffness and excessive pressure pulsatility have emerged as important risk factors for a number of common disorders of aging, including cardiovascular disease, stroke, cognitive impairment, and renal disease. The triple-threat combination of robust associations between arterial stiffness and the foregoing disorders, a marked increase in arterial stiffness with advancing age ...

although measurement of intracranial pressure by noninvasive methods has been suggested, but mainly invasive methods are used for this purpose-increase in episcleral venous pressure can be expected to result in a linear increase in intraocular pressure. congested oculat veins with capillary leakage and hemorrhage are seen when the icp is increased, thus theoretically measurement of intraocular ...

Tritiated leucine was injected into the vitreous of owl monkeys (Aotus trivirgatus) to make it available to retinal ganglion cells for protein synthesis. Intraocular pressure was maintained for eight hours at selected levels between 15 and 105 mm. Hg. Autoradiography and scintillation counting were used to follow the movement of the labeled protein along the axons from the retinal ganglion cell...

BACKGROUND Cryptococcal meningitis is associated with increased intracranial pressure (ICP). Therapeutic lumbar puncture (LP) is recommended when the initial ICP is >250 mm H2O, yet the availability of manometers in Africa is limited and not always used where available. We assessed whether intraocular pressure could be a noninvasive surrogate predictor to determine when additional therapeutic L...

Physical exercise in humans induces changes intraocular pressure, relating to the type and intensity of workload. The purpose present study was evaluate variations pressure arterial blood dogs that underwent physical on a treadmill. Thirty were submitted consisting walking (15 minutes), trotting (20 (10 minutes). pulse rate recorded for each dog before starting treadmill exercise, immediately a...
