Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

1.1K
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...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption

861
As individuals age, their body's physiology evolves, affecting drug pharmacokinetics. The most apparent changes occur in the gastrointestinal tract, where an increase in gastric pH, a delay in gastric emptying, and a reduction in gastrointestinal motility are observed. Remarkably, these changes do not substantially modify the absorption of orally administered drugs, particularly those absorbed via passive diffusion.Transdermal drug delivery emerges as a highly viable method for older adults due...

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...

Ophthalmic Drug Delivery Systems

283
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...

Drug Dosing: Geriatric Patients

395
Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...

Angle Closure Glaucoma: Treatment01:28

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...

Summary

White patients demonstrated higher adherence to glaucoma medications compared to non-White patients. Addressing patient-reported problems is crucial for improving medication adherence self-efficacy in glaucoma care.

Area of Science:

  • Ophthalmology
  • Public Health
  • Behavioral Science

Background:

  • Glaucoma medication adherence is critical for preventing vision loss.
  • Factors influencing adherence and self-efficacy require further investigation.
  • Objective measurement of adherence is essential for accurate assessment.

Purpose of the Study:

  • To identify factors associated with objectively measured adherence to glaucoma medications.
  • To explore the relationship between patient race, reported problems, and medication adherence.
  • To assess glaucoma medication adherence self-efficacy.

Main Methods:

  • Cross-sectional study at two glaucoma referral centers.
  • Utilized Medication Events Monitoring System (MEMS) for adherence measurement.
  • Assessed self-reported problems and adherence self-efficacy using validated scales.

Main Results:

  • 71% of patients reported at least one problem using glaucoma medications.
  • White patients were over 3 times more likely to be 80% adherent than non-White patients.
  • Increased duration of glaucoma correlated with higher adherence self-efficacy; more problems correlated with lower self-efficacy.

Conclusions:

  • Eye care providers should routinely assess patient-reported problems.
  • Interventions to reduce medication use problems can enhance adherence self-efficacy.
  • Addressing patient-specific challenges is key to improving glaucoma medication adherence.
