Dynamic Contour Tonometry in Comparison to Intracameral IOP Measurements

Investigative Opthalmology & Visual Science, 2008
The purpose of the study was to examine the effect of central corneal thickness (CCT), corneal curvature, astigmatism, axial length (AL), and age on measurements with the Pascal Dynamic Contour Tonometer (DCT).In a prospective clinical trial 75 eyes of 75 patients undergoing phacoemulsification were examined.

Different methods for measuring intraocular pressure [PDF]

Halo 194, 2019
Tonometry is a method for measuring intraocular pressure (IOP). Goldmann applanation tonometry (GAT) represents a golden standard for measuring IOP. The measurement is conducted by measuring the force needed to straighten out a certain area of the cornea.

Incidence and risk factors of nocturnal penetrations and aspirations in patients with obstructive sleep apnea during drug‐induced sedation endoscopy

Journal of Sleep Research, Volume 34, Issue 1, February 2025.
Summary Obstructive sleep apnea has been linked to an increased risk of pneumonia, possibly due to higher rates of nighttime aspirations. Few studies have directly investigated such aspirations in individuals with sleep apnea. This retrospective study included 142 adult patients with obstructive sleep apnea who underwent drug‐induced sedation endoscopy

Predicting Candidacy for Unilateral Hypoglossal Nerve Stimulation Without Drug‐Induced Sleep Endoscopy

OTO Open, Volume 9, Issue 1, January-March 2025.
Abstract Objective Patients undergo a drug‐induced sleep endoscopy before unilateral hypoglossal nerve stimulation. This study aims to reduce the need for preoperative drug‐induced sleep endoscopy by predicting favorable collapse patterns at the velum based on clinical examination and sleep study data.

Chronic hyperglycemia alters retinal astrocyte microstructure and uptake of cholera toxin B in a murine model of diabetes

Journal of Neurochemistry, Volume 169, Issue 1, January 2025.
Compared to control animals, retinal astrocytes from diabetic animals increase the frequency of pad motifs while decreasing extension of bristle motifs. They additionally uptake more exogenous cholera toxin B (CTB) than control. When diabetic conditions are coupled with intravitreal injury, increases in both pads and bristles occur. A large increase in
