PURPOSE To detect changes in local blood supply to central, middle, and peripheral retina following acute high intraocular pressure and to investigate the effects of changes in local retinal blood supply on the selective loss of retinal ganglion cells. METHODS The acute high intraocular pressure model of Sprague-Dawley rats was established by increasing the anterior chamber pressure to 110 mm...

Achievement of target intraocular pressure is the goal of every efficient antiglaucoma therapy. Target intraocular pressure is the level of intraocular pressure which is associated with minimal likelihood of visual field or optic nerve lesion, or an existing lesion progression due to elevated intraocular pressure. Results of large clinical studies which have offered some new concepts on target ...

purpose : to evaluate intraocular pressure (iop) and anterior chamber depth (acd) change after phacoemulsification with posterior chamber intraocular lens implantation methods : in this quasi-experimental study, 84 patients with senile cataract were included. all patients had normal iop. patients with traumatic and complicated cataract, any history of uveitis, glaucoma, or other ocular disease ...

Acute common carotid occlusion in rabbits causes a reduction in ocular blood volume and ciliary artery blood pressure. At all levels of intraocular pressure, cervical sympathetic stimulation reduces these changes. The ocidar blood volume reduction after acute common carotid occlusion is not linearly related to the absolute blood pressure change or to the lowest blood pressure reached in the cil...

background: ramadan fasting may alter a variety of physiological parameters which by themselves influence ocular system. here, we review the effects of ramadan fasting on the health and function of the eye. materials and methods: literature records in  pubmed/medline, web of science, embase, google scholar, and iran medex databases as well as proceedings of related meetings  from january 1986 t...

results this review explores the relationship between metabolic syndrome, including all its components, and various ocular conditions such as retinopathy, central retinal artery occlusion, cataract and elevated intraocular pressure. context metabolic syndrome (metabolic syndrome x) is a prevalent cluster of risk factors that include high bmi, hypertension, insulin resistance and dyslipidemia. i...

the ophthalmologic outcomes of diabetes were important. this research is conducted to assess the relation between diabetes and intraocular pressure changes in the patients of avicenna hospital, compared with healthy persons referring to the facility. with cross-sectional research, 400 persons including 200 diabetics and non-diabetics were selected on a random basis over one year in 2012. resear...

The relationship between intraocular and systemic blood pressures was investigated in a prospective study of 572 middle-aged men. There was no consistent relationship between intraocular pressure at first visit and age. Subjects with an intraocular pressure greater than 20 mm Hg had a significantly higher systolic blood pressure than controls matched for age. An autoregressive model was used to...
