Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

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: Treatment01:28

Angle Closure Glaucoma: Treatment

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

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...
Ophthalmic Drug Delivery Systems01:23

Ophthalmic Drug Delivery Systems

Ophthalmic drug delivery faces major limitations due to poor absorption across the corneal membrane. This process is primarily driven by diffusion and is influenced by two main factors: the physicochemical properties of the drug and tear drainage. Most ophthalmic drugs, such as pilocarpine, epinephrine, atropine, and local anesthetics, are weak bases. They are typically formulated at an acidic pH to enhance chemical stability. However, this leads to high ionization, reducing their ability to...

Area of Science:

  • Ophthalmology
  • Geriatric Nursing

Background:

  • Chronic open angle glaucoma (COAG) is a progressive optic neuropathy affecting older adults.
  • Effective management is essential to prevent vision loss and maintain quality of life.

Purpose of the Study:

  • To provide a comprehensive overview of COAG for nursing professionals.
  • To outline best practices in nursing care and management of older adults with COAG.

Main Methods:

  • Literature review on COAG pathogenesis, clinical features, and etiology.
  • Synthesis of current approaches to care and treatment, emphasizing patient education and adherence.

Main Results:

  • COAG diagnosis involves visual field testing, tonometry, and optic nerve assessment.
  • Management strategies include pharmacotherapy, laser therapy, and surgery.
  • Patient education and adherence are key for long-term self-management in community settings.

Conclusions:

  • Nurses play a vital role in educating and supporting older adults with COAG.
  • Promoting adherence to medical therapy empowers patients for independent self-management.
  • Integrated community-based care is essential for managing COAG in the elderly population.
