Current hydration assessments involve biological fluids that are either compromised in dehydrated individuals or require laboratory equipment, making timely results unfeasible. The eye has been proposed as a potential site to provide a field-based hydration measure. The present study evaluated the efficacy and sensitivity of intraocular pressure (IOP) to assess hydration status. Twelve healthy ...

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...

BACKGROUD To assess the noninferiority of a dorzolamide-timolol fixed combination (DTFC) versus latanoprost in terms of intraocular pressure (IOP) and to compare blood pressure (BP), ocular perfusion pressure (OPP) and diastolic ocular perfusion pressure (DOPP) between the latanoprost and DTFC groups in patients with normal-tension glaucoma (NTG). METHODS Prospective, interventional, randomiz...

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...
