Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

1.5K
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

1.1K
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: Overview

1.6K
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...

Focusing of Light in the Eye01:16

Focusing of Light in the Eye

7.0K
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...

Summary

Myopia is linked to a lower prevalence of occludable angles, despite longer axial lengths. Axial length is a key factor in determining occludable angles in the aging Chinese population.

Area of Science:

  • Ophthalmology
  • Public Health
  • Ocular Biometry

Background:

  • Myopia is often associated with longer axial lengths, deeper anterior chambers, and open angles.
  • The Jiangning Eye Study investigated the relationship between myopia and occludable angles in a Chinese population.

Purpose of the Study:

  • To determine if myopia influences the prevalence of occludable angles.
  • To explore the association between axial length and occludable angles in different refractive error groups.

Main Methods:

  • A population-based study of 2044 individuals aged 50+ in Shanghai.
  • Ophthalmic examinations included axial length, anterior chamber depth, and spectral domain optical coherence tomography.

Main Results:

  • The prevalence of iris trabecular meshwork contact was 1.25% in myopic subjects, 6.44% in emmetropia, and 7.43% in hyperopia.
  • Myopic subjects exhibited iris trabecular meshwork contact and shallow anterior chamber depth, even with long axial lengths.

Conclusions:

  • Myopia is associated with a lower prevalence of iris trabecular meshwork contact compared to emmetropia and hyperopia.
  • Axial length is a significant factor associated with occludable angles.
