Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

386
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...

Focusing of Light in the Eye01:16

Focusing of Light in the Eye

2.2K
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...

Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

432
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...

Glaucoma: Overview01:25

Glaucoma: Overview

496
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...

Summary
This summary is machine-generated.

Optometrists in Hong Kong are increasingly recommending myopia control (MC) for children. Myopia control spectacle lenses became the most popular method between 2017 and 2021.

Area of Science:

  • Ophthalmology
  • Pediatric Optometry
  • Public Health

Background:

  • Myopia is a growing public health concern in children.
  • Effective myopia management strategies are crucial to prevent high myopia and associated ocular pathologies.
  • Understanding current clinical practices in myopia management is essential for guiding future interventions.

Purpose of the Study:

  • To investigate the trends in myopia management strategies employed by optometrists for myopic and pre-myopic children in Hong Kong.
  • To analyze the types of myopia control (MC) interventions recommended and their prevalence over a five-year period.

Main Methods:

  • Retrospective review of clinical files for 1,318 children aged 6-10 years from 2017-2021.
  • Children were categorized as myopes or pre-myopes based on initial spherical equivalent refractive error.
  • Analysis of demographic data, refractive error progression, and recommended myopia management strategies.

Main Results:

  • A significant shift in myopia management recommendations was observed from 2017 to 2021 (p < 0.001).
  • The proportion of children recommended for myopia control increased from 18.4% to 42.8%.
  • Myopia control spectacle lenses became the most recommended option, rising from 7.3% to 36.8%, while orthokeratology, MC contact lenses, and atropine remained below 5%.

Conclusions:

  • Myopia management practices in Hong Kong optometrists have significantly evolved towards increased myopia control recommendations.
  • Myopia control spectacle lenses are now the predominant method for managing myopia in children.
  • Early intervention in younger pre-myopic children appears to correlate with more timely management updates.
