Glaucoma: Overview01:25

Glaucoma: Overview

1.4K
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

996
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

1.3K
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...

Fixed Action Patterns01:06

Fixed Action Patterns

17.6K
A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.

Characteristics of Practical Op Amps01:16

Characteristics of Practical Op Amps

862
A difference amplifier, a crucial component in numerous electronic devices, ideally amplifies only the difference-mode signal, which is the difference between two input signals. However, in practical circuits, the output voltage depends on both the differential gain and the common-mode gain.
The ratio of differential gain to the common-mode gain is defined as the common-mode rejection ratio (CMRR). This ratio quantifies the ability of operational amplifiers (op-amps) to reject common-mode...

Theoretical Foundations of Nursing Practice01:30

Theoretical Foundations of Nursing Practice

17.4K
Theories play an essential role in organizing patient care. Theories refer to a proposed or followed belief, policy, or procedure that is the basis for action. Nursing theories are knowledge-based concepts that guide nurses' actions, influence nursing education and practice, and allow nurses to care for their patients.
Theories provide a perspective to assess patients' conditions and organize data and methods. They also assist in analyzing and interpreting information. They represent a...

Summary
This summary is machine-generated.

Glaucoma care costs are rising, driven by increased procedures like laser therapy and implants, despite a decline in medication use. Optometrists are increasingly involved in diagnostic testing for glaucoma management.

Area of Science:

  • Ophthalmology
  • Public Health
  • Health Economics

Background:

  • The demand for glaucoma care is increasing due to an aging population.
  • Understanding practice patterns is crucial for effective glaucoma management.

Purpose of the Study:

  • To characterize trends in Australian glaucoma management practices from 2003 to 2017.
  • To analyze changes in medication use, procedures, and diagnostic services.

Main Methods:

  • Retrospective audit of Medicare Benefits Schedule (MBS) reimbursements and Pharmaceutical Benefits Scheme (PBS) prescriptions.
  • Analysis of per capita service utilization and costs within the Australian Medicare-eligible population.

Main Results:

  • Glaucoma medication prescriptions and expenditure declined after peaking in 2015.
  • Significant increases observed in laser procedures, glaucoma drainage device insertions, and ab interno trabecular micro-bypass.
  • Optometrist utilization of computerized perimetry dramatically increased, exceeding ophthalmologist-initiated perimetry.

Conclusions:

  • This study marks the first recorded decline in glaucoma medication use and expenditure since 1992.
  • Glaucoma management is shifting towards increased surgical and laser interventions, with a growing role for optometrists in diagnostics.
  • While perimetry costs have risen, overall cost increases are moderated by reduced medication expenditure.
