Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

520
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...

Angle Closure Glaucoma: Treatment

613
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...

Glaucoma: Overview01:25

Glaucoma: Overview

679
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...

Area of Science:

  • Medical Education
  • Ophthalmology
  • Emergency Medicine

Background:

  • Ocular tonometry is crucial for diagnosing and managing ocular emergencies.
  • Accurate intraocular pressure measurement guides critical treatment decisions.
  • A need exists for accessible, realistic training tools for this skill.

Purpose of the Study:

  • To develop and assess an affordable, reproducible task trainer for ocular tonometry.
  • To improve Emergency Medicine resident and medical student proficiency in tonometry.

Main Methods:

  • A swine eye model was created using an angiocatheter inserted through the optic nerve stump.
  • Intraocular pressure was manipulated in real-time using a saline-filled syringe.
  • The model was optionally integrated into a mannequin head for enhanced realism.

Main Results:

  • Thirty-six learners participated, showing significant improvements in comfort (3.26 to 7.64) and confidence (3.11 to 7.56) in performing tonometry.
  • Learners rated the task trainer highly (mean 9.19) for increasing comfort and ability.
  • The trainer demonstrated effectiveness in educational settings.

Conclusions:

  • A low-cost, easily constructed ocular tonometry task trainer was successfully developed.
  • The task trainer led to significant improvements in learner comfort and confidence.
  • This tool offers a valuable resource for training eye care skills in emergency medicine.
