Glaucoma: Overview01:25

Glaucoma: Overview

1.1K
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...

Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

870
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

1.0K
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...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption

141
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...

Hypertension III: Clinical Manifestations and Diagnostic Studies

350
Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...

Area of Science:

  • Ophthalmology
  • Primary Care Medicine
  • Medical Education

Background:

  • Glaucoma is a leading cause of irreversible blindness.
  • Optic nerve damage in glaucoma necessitates early detection and management.
  • Frontline physicians play a critical role in identifying and referring glaucoma patients.

Purpose of the Study:

  • To assess glaucoma knowledge among primary and secondary care physicians in Riyadh, Saudi Arabia.
  • To evaluate physicians' examination, management, and referral practices for glaucoma.
  • To identify gaps in physician competency regarding glaucoma care.

Main Methods:

  • Cross-sectional study involving 126 physicians (GPs, emergency, internal, family physicians).
  • Utilized a validated self-administered questionnaire covering demographics, glaucoma risk factors, knowledge, examination, management, and referral.
  • Data collected from physicians in Riyadh-based hospitals and medical centers.

Main Results:

  • Overall glaucoma knowledge score was suboptimal at 34.2%.
  • 88.7% of physicians felt unqualified to manage glaucoma, despite awareness of some medications.
  • While 93.7% recognized the need for urgent referral for elevated intraocular pressure, only 33.3% were comfortable with tonometry.

Conclusions:

  • A significant majority of physicians exhibit poor glaucoma knowledge, impacting their referral practices.
  • There is a critical need to enhance glaucoma awareness, examination skills, and referral practices among frontline physicians.
  • Interventions targeting physician education are essential to mitigate glaucoma-related vision impairment.
