background: in many clinical situations, knowledge of central venous pressure (cvp) is important.  measurement of cvp is not always possible.   objective: to determine if intraocular pressure (iop) can be used as an estimate for cvp.   methods: iop and cvp were measured concurrently in 30 candidates of coronary artery bypass graft surgery.  those with carotid artery or jugular venous diseases a...

LETTERS Spontaneous venous pulsations should be monitored during glaucoma therapy It is well established that lowering intraocular pressure slows or halts progression of glau-coma. None the less, changes in intracranial pressure also affect the pressure gradient across the lamina cribrosa. Normal intraocu-lar pressures combined with low intracranial pressures produce the same pressure different...

The influence of common carotid occlusion on intraocular pressure was studied in rabbits by perfusion and tonographic techniques. Bilateral common carotid occlusion caused a greater ocular volume change than homolateral occlusion. If homolateral occlusion was followed by contralateral occlusion, there was consistently an additional fall in intraocular pressure. The initial fall in intraocular p...

OBJECTIVE The aim of this study was to investigate the association between intraocular pressure and metabolic syndrome by comparing central corneal thicknesses. METHODS One hundred sixty-two subjects were enrolled in this cross-sectional study, with 89 subjects in a metabolic syndrome group and 73 subjects in a control group. Ophthalmological examinations, including intraocular pressure and c...

In our long term evaluation of patients with Hansen's disease we have frequently found reduction of their intraocular pressure. Furthermore, we noted changes in their intraocular pressure on change of posture. To determine if these changes have any significance we measured the intraocular pressures of 24 experimentally infected and 39 control monkeys in both sitting and reclining positions. We ...

OBJECTIVE To determine whether there was a correlation between tonometric measurements of the intraocular pressure and transducer measurements of the intracranial pressure in the acute setting, and whether intraocular pressure can be used as a surrogate measure of intracranial pressure. Children with traumatic brain injuries commonly develop increased intracranial pressure requiring surgical pl...

OBJECTIVE To evaluate intraocular pressure in very low birth weight preterm infants and correlate it with postconceptional age. METHODS The intraocular pressure in a prospective cohort of very low birth weight premature infants (defined as a birth weight ≤1,500 g and gestational age ≤32 weeks) admitted to Hospital de Clínicas de Porto Alegre , Brazil was evaluated weekly. The evaluated outcom...

BACKGROUND Although the association between metabolic syndrome and intraocular pressure is well known, the relationship between the intraocular pressure and different combination of the components of metabolic syndrome has not been actively researched yet. The study aimed to investigate the relationship between the intraocular pressure and metabolic syndrome components with their different comb...

Adenine dinucleotides are present in many biological systems and may serve as physiological regulators of processes such as neurotransmitter release, vascular tone or corneal hydration. The presence of diadenosine polyphosphates was investigated in New Zealand White rabbit aqueous humor. Diadenosine tetraphosphate (Ap4A) and diadenosine pentaphosphate (Ap5A) were identified and quantified in th...
