Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

389
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
Drugs such as carbonic anhydrase inhibitors, α2- and...

Glaucoma: Overview01:25

Glaucoma: Overview

497
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

433
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

Errors occurring during blood pressure monitoring

588
Blood pressure monitoring is a crucial clinical procedure in diagnosing and managing various cardiovascular conditions. Despite its significance, the accuracy of blood pressure measurements can be compromised by multiple factors, potentially leading to either falsely high or low readings. These inaccuracies are critical as they can significantly impact patient care. So, it is vital to understand these challenges deeply and adopt strategic approaches to minimize errors.
Several factors...

Pre-Procedural Guidelines for Assessing Blood Pressure

520
Accurate blood pressure assessment is crucial for diagnosing and managing various health conditions. To ensure the reliability of these measurements, healthcare professionals must adhere to standardized pre-procedural guidelines. These guidelines enhance patient safety and improve the overall quality of healthcare. The following steps are essential for obtaining accurate and consistent blood pressure readings, from using the appropriate tools to ensuring effective communication with the...

Area of Science:

  • Ophthalmology
  • Medical Devices
  • Patient Experience

Background:

  • Glaucoma management requires regular intraocular pressure (IOP) monitoring.
  • Home-based tonometry offers a potential solution for frequent IOP measurements.

Purpose of the Study:

  • To evaluate patient experiences with the iCare HOME tonometer.
  • Assess ease of use, usage patterns, and proficiency with the device.
  • Gather patient feedback on home tonometry.

Main Methods:

  • Prospective survey-based cohort study.
  • 19 patients with glaucoma or glaucoma suspect diagnoses.
  • One-week loan of iCare HOME tonometer with daily multiple measurements and participant journaling/surveys.

Main Results:

  • Patients measured IOP ≥4 times/day/eye.
  • 75% found the tonometer moderately or very easy to use.
  • 94% comfortable using the device, 88% used it independently.
  • Proficiency typically achieved by day 3.
