Glaucoma: Overview01:25

Glaucoma: Overview

1.0K
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: Treatment01:28

Angle Closure Glaucoma: Treatment

926
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...

Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

801
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...

Accessory Structures of the Eye01:17

Accessory Structures of the Eye

2.4K
Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...

Photoreceptors and Visual Pathways01:22

Photoreceptors and Visual Pathways

7.6K
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...

Area of Science:

  • Health Services Research
  • Optometry
  • Evidence-Based Practice

Background:

  • A persistent gap exists between clinical research findings and actual patient care.
  • Evidence-based practice (EBP) was developed to address this gap but challenges remain.
  • Knowledge translation (KT) and implementation science (IS) have emerged to facilitate research integration into practice.

  • To revisit the foundational concepts of evidence-based practice.
  • To introduce knowledge translation and implementation science.
  • To explore the roles of EBP, KT, and IS in improving glaucoma care provided by optometrists.

Main Methods:

  • Literature review of evidence-based practice, knowledge translation, and implementation science.
  • Exploration of the application of these concepts in optometric glaucoma care.

Main Results:

  • Evidence-based practice provides a framework for using research in practice.
  • Knowledge translation focuses on moving evidence from research to practice.
  • Implementation science studies methods for integrating evidence into routine care.

Conclusions:

  • Knowledge translation and implementation science offer valuable strategies to bridge the research-practice gap.
  • These fields are crucial for enhancing the delivery of appropriate glaucoma care by optometrists.
  • Further exploration of KT and IS is needed to optimize clinical outcomes in optometry.
