Accessory Structures of the Eye01:17

Accessory Structures of the Eye

2.3K
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...

Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

900
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

771
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...

Glaucoma: Overview01:25

Glaucoma: Overview

1000
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...

PPE Use in Healthcare Settings II: Doffing01:10

PPE Use in Healthcare Settings II: Doffing

1.3K
The sequence of removing or doffing PPE starts with the gloves, as they are the most contaminated. Next is removal of the face shield or goggles, as they would interfere with removing other PPE. Then remove the gown, followed by the mask or respirator. Perform hand hygiene between steps if hands become contaminated and immediately after removing all PPE. Generally, the outside front and sleeves of the isolation gown, the goggles or the mask, the respirator, and the face shield are contaminated.

Area of Science:

  • Occupational Health
  • Ophthalmology
  • Public Health

Background:

  • Increased attention on eye health post-COVID-19 pandemic.
  • Exploration of impacts from mask wearing, delayed eye exams, and increased screen time on worker vision.
  • Growing concern for worker visual health in the modern workplace.

Purpose of the Study:

  • To explore the multifaceted impacts of recent lifestyle and environmental changes on worker vision.
  • To identify key considerations for maintaining and improving eye health in occupational settings.
  • To establish the role of occupational health professionals in addressing eye health concerns.

Main Methods:

  • Convened a Round Table discussion with leading experts in occupational health, risk management, eye health, and communication.
  • Focused expert discussions on literature concerning mask wearing, communication for eye care appointments, and increased screen time.
  • Gathered expert consensus on essential eye health considerations for workers.

Main Results:

  • Experts reached a consensus on the necessity of implementing comprehensive eye health considerations.
  • Recommendations include addressing both clinical eye care and protective measures against occupational eye injuries.
  • Highlighted the link between environmental factors (masks, screens) and potential vision impairment.

Conclusions:

  • Occupational health professionals are vital for assessing and training workers on eye health.
  • Emphasized the need for proactive strategies to safeguard worker vision.
  • Advocated for integrating eye health into broader occupational safety and risk management frameworks.
