Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

1.0K
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

1.7K
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: Treatment

1.6K
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
  • Public Health

Background:

  • Increasing life expectancy in the UK drives demand for hospital glaucoma services.
  • The Cambridge community Optometry Glaucoma Scheme (COGS) was established in 2010 to address this demand.
  • COGS utilizes community optometrists with specialized glaucoma interest for initial patient evaluations.

Purpose of the Study:

  • To evaluate the effectiveness and safety of the COGS program.
  • To assess the reduction in false-positive referrals to hospital-based glaucoma services.
  • To determine the impact of community-based screening on healthcare resource utilization.

Main Methods:

  • 1733 patients with suspected glaucoma were evaluated between 2010 and 2013.
  • Community optometrists conducted clinical assessments including tonometry, pachymetry, optic disc photography, and visual field testing.
  • Electronic transmission of clinical data for virtual review and validation by consultant ophthalmologists.

Main Results:

  • 46.6% of patients were discharged after initial assessment.
  • An additional 5.7% were discharged following virtual review by a consultant.
  • 2.8% of initially discharged patients were recalled for further review, and 10.5% were discharged after a single hospital visit.

Conclusions:

  • The COGS program demonstrates a safe and effective model for community-based glaucoma screening.
  • The scheme successfully reduces the number of false-positive glaucoma referrals to hospitals.
  • Community-based evaluation of glaucoma suspects optimizes healthcare resource allocation.
