Focusing of Light in the Eye01:16

Focusing of Light in the Eye

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

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

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

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...

Area of Science:

  • Ophthalmology
  • Optometry
  • Pediatric Eye Care

Background:

  • Myopia, a common refractive error, is progressing globally, particularly in children.
  • Peripheral hyperopia is hypothesized to be a driver of axial elongation and myopia progression.
  • Effective myopia control strategies are crucial for preventing high myopia and associated ocular pathologies.

Purpose of the Study:

  • To evaluate the efficacy of novel optical contact lenses in slowing myopia progression.
  • To determine if reducing relative peripheral hyperopia with contact lenses impacts refractive development.
  • To assess the 12-month impact of this intervention on spherical equivalent and axial length changes in children.

Main Methods:

  • A randomized controlled trial involving Chinese children aged 7-14 years with existing myopia.
  • Participants were fitted with either novel myopia-controlling contact lenses or standard single-vision spectacles.
  • Follow-up included refractive error and axial length measurements over a 12-month period.

Main Results:

  • Novel contact lenses demonstrated a 34% reduction in spherical equivalent progression compared to spectacles (-0.57 D vs. -0.86 D).
  • Axial length increase was significantly reduced by 33% in the contact lens group (0.27 mm vs. 0.40 mm).
  • These findings were statistically significant after adjusting for relevant confounding factors.

Conclusions:

  • The study supports the hypothesis that correcting peripheral hyperopia can modulate central refractive development.
  • Novel optical contact lenses represent a promising intervention for slowing myopia progression in pediatric populations.
  • Further research can explore long-term efficacy and broader applicability of this myopia control method.
