Glaucoma: Overview01:25

Glaucoma: Overview

573
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

452
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

500
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...

Accessory Structures of the Eye01:17

Accessory Structures of the Eye

1.6K
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...

Area of Science:

  • Ophthalmology and Public Health

Context:

  • 1.1 billion people globally experience visual impairment.
  • 90% of visual impairment is preventable or treatable.
  • Significant disparities exist in eye health coverage, particularly in low-resource regions.

Purpose:

  • To outline the goals of global ophthalmology in maximizing vision and ocular health.
  • To address the challenges of widespread visual impairment and unequal access to eye care.
  • To transition from the VISION 2020 initiative to the new "2030 IN SIGHT" campaign.

Summary:

  • The VISION 2020 campaign aimed to eliminate avoidable blindness.
  • Key achievements, challenges, and lessons learned from VISION 2020 have informed the "2030 IN SIGHT" strategy.
  • The new campaign focuses on sustainable, integrated eye care services worldwide.

Impact:

  • Enhancing quality of life and social inclusion through improved vision.
  • Promoting cost-effective interventions for preventing and treating visual impairment.
  • Advocating for universal access to essential eye health services.
