Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

413
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: Overview

528
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

454
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...

Area of Science:

  • Ophthalmology
  • Surgical Education

Background:

  • Surgical skill training in ophthalmology is crucial for patient safety and outcomes.
  • Access to traditional and modern training resources is limited, particularly in resource-constrained environments.
  • Glaucoma surgery requires specialized skills that demand extensive practice.

Purpose of the Study:

  • To develop and evaluate innovative, low-cost do-it-yourself (DIY) surgical training models for glaucoma.
  • To utilize readily available hospital waste materials for creating these training models.
  • To enhance surgical proficiency among ophthalmic trainees in a cost-effective manner.

Main Methods:

  • Development of several DIY models using hospital waste materials.
  • Models designed for practicing various glaucoma surgical procedures.
  • Trainees (ophthalmic assistants, fellows, junior consultants) practiced procedures on these models.

Main Results:

  • Models facilitated practice of procedures including tonometry, central corneal thickness measurement, laser suture lysis, laser iridotomy, anterior chamber decompression, bleb needling, trabeculectomy flap construction, and suturing.
  • DIY models provide a viable alternative to expensive training resources.
  • Enhanced surgical skill acquisition and confidence among trainees.

Conclusions:

  • Innovative, low-cost DIY models using hospital waste are effective for glaucoma surgical training.
  • These models address the limitations of traditional training resources, especially in resource-limited settings.
  • The approach can boost trainee confidence and help meet the demand for skilled glaucoma surgeons.
