High quality factor parylene-based intraocular pressure sensor

2012 7th IEEE International Conference on Nano/Micro Engineered and Molecular Systems (NEMS), 2012
A new concept of the intraocular pressure (IOP) sensor design and its implantation approach are presented in this paper. A parylene-based sensing part with about 30 µm in thickness was fabricated, and then integrated with an implantation tube attached to sensor's backside pressure access hole.

Quality of Controlled Clinical Trials on Glaucoma and Intraocular High Pressure

Journal of Glaucoma, 2005
To study the quality of controlled clinical trials on glaucoma.Two hundred and twenty-six clinical trials published between 1980 and 1999 were selected from seven international ophthalmological journals. Their quality was assessed by four researchers with epidemiological skills using a structured questionnaire.Sample size was pre-estimated in 34 (15.0%)

Intraocular pressure variation from ocular compression in low and high myopia

Clinical and Experimental Optometry, 2023
Change in intraocular pressure during acute ocular compression is related to aqueous humour dynamics. Monitoring intraocular pressure (IOP) change throughout ocular compression has potential to evaluate aqueous outflow facilities.Recent studies have monitored lamina cribrosa deformation using optical coherence tomography during ocular compression.

Baroreceptors mask sympathetic responses to high intraocular pressure in dogs

Autonomic Neuroscience, 2008
These experiments were designed to investigate whether increasing intraocular pressure (IOP) in anesthetized dogs produces differential control of sympathetic nerve activities to various organs (heart, kidney, liver, and spleen) and if these sympathetic responses are modified by baroreceptors.

High Altitude-associated Changes in Intraocular Pressure Abrogated by Trabeculectomy

Journal of Glaucoma, 2017
Purpose: To highlight the effect of ascent to high altitude on intraocular pressure (IOP) in a patient with primary open-angle glaucoma, who had previously undergone trabeculectomy in 1 eye. Methods: Case report.

Identification of High Intraocular Pressure Responders to Topical Ophthalmic Corticosteroids

Journal of Ocular Pharmacology and Therapeutics, 1993
To locate suitable candidates to study the intraocular pressure (IOP) effects of new ocular steroids, healthy volunteers must be challenged with topically applied steroids to verify that such individuals are indeed high "steroid responders"; that is, they respond with IOP elevations of at least 5 mmHg during a 4- to 6-week challenge with the topically ...

High intraocular pressure produces learning and memory impairments in rats

Brain Research, 2017
Primary open angle glaucoma (POAG) is a leading cause of irreversible blindness worldwide. Previous MRI studies have revealed that POAG can be associated with alterations in hippocampal function. Thus, the aim of this study was to investigate a relationship between chronic high intraocular pressure (IOP) and hippocampal changes in a rat model.

PREVENTING A HIGH RISE IN INTRAOCULAR PRESSURE AFTER LASER TRABECULOPLASTY

Australian and New Zealand Journal of Ophthalmology, 1987
Abstract The high rise in pressure which sometimes follows laser trabeculoplasty is a serious and sight‐threatening complication in patients with advanced glaucoma. In a previous study we found that patients undergoing laser trabeculoplasty were very unlikely to have a high rise in pressure if the initial pressure was less than 20 mmHg.

Corneal Biomechanical Properties and Intraocular Pressure in High Myopic Anisometropia

Eye & Contact Lens: Science & Clinical Practice, 2010
To investigate corneal biomechanical properties and intraocular pressure (IOP) in patients with high myopic anisometropia.Patients with high myopic anisometropia (n = 23) and emmetropic subjects (n = 55) were enrolled. Corneal hysteresis (CH), Goldmann-correlated intraocular pressure (IOPg), corneal resistance factor, and corneal-compensated IOP (IOPcc)
