Focusing of Light in the Eye01:16

Focusing of Light in the Eye

6.2K
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...

Glaucoma: Overview

1.7K
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: 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...

Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

1.6K
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...

Area of Science:

  • Ophthalmology
  • Public Health
  • Epidemiology

Background:

  • Refractive errors are a significant cause of visual impairment globally.
  • Understanding the prevalence of refractive errors is essential for public health planning.

Purpose of the Study:

  • To determine the prevalence of refractive errors in adults aged 40-80 in Yazd, central Iran.
  • To investigate age and sex-specific differences in refractive error distribution.

Main Methods:

  • A population-based study utilizing multi-stage random cluster sampling.
  • Inclusion of 2,098 adult participants (aged 40-80) from Yazd.
  • Comprehensive eye examinations including manifest refraction and retinoscopy.

Main Results:

  • Over half the population exhibited refractive errors, with astigmatism (53.8%) and myopia (36.5%) being most prevalent.
  • Prevalence of hyperopia, astigmatism, and anisometropia increased with age.
  • Myopia was more prevalent in females, while against-the-rule astigmatism increased with age.

Conclusions:

  • The study reveals a high prevalence of refractive errors in Yazd, exceeding previous Iranian estimates for myopia and astigmatism.
  • Refractive errors pose a significant public health concern due to their impact on avoidable visual impairment.
  • Findings underscore the need for targeted interventions and continued surveillance of refractive error prevalence.
