Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

997
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

864
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

1.1K
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

4.7K
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...

Area of Science:

  • Neuroscience
  • Ophthalmology
  • Developmental Biology

Background:

  • Amblyopia treatment traditionally involves patching the strong eye, effective mainly in early childhood.
  • This approach is limited by the concept of a critical sensitive period for visual development.

Purpose of the Study:

  • To review advancements in understanding amblyopia over the past 20 years.
  • To evaluate novel therapeutic strategies for amblyopia in children and adults.
  • To reconcile laboratory successes with clinical trial outcomes.

Main Methods:

  • Review of recent scientific literature on amblyopia.
  • Analysis of neural mechanisms, behavioral outcomes, and therapeutic interventions.
  • Focus on perceptual learning, video game-based therapy, and binocular approaches.

Main Results:

  • Neural plasticity in amblyopia extends beyond early childhood.
  • New therapies emphasize binocular approaches over traditional monocular patching.
  • Novel treatments show mixed success in clinical trials, highlighting treatment challenges.

Conclusions:

  • Amblyopia is a fundamentally binocular disorder, necessitating binocular treatment strategies.
  • Persistence of plasticity offers opportunities for adult amblyopia treatment.
  • Further research is needed to bridge the gap between lab findings and clinical efficacy.
