Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

473
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

427
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

541
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

2.7K
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:

  • Ophthalmology
  • Corneal Surgery
  • Refractive Errors

Background:

  • Corneal transplantation significantly enhances visual acuity and quality of life.
  • Post-keratoplasty astigmatism is a common complication that impairs visual outcomes.
  • Effective management of astigmatism is crucial for maximizing vision after corneal grafts.

Purpose of the Study:

  • To review and collate available management strategies for post-operative astigmatism following corneal transplantation.
  • To provide a comprehensive resource for clinicians on addressing astigmatism after keratoplasty.
  • To facilitate comparison between different treatment modalities for post-keratoplasty astigmatism.

Main Methods:

  • A comprehensive literature search was conducted to identify studies on post-keratoplasty astigmatism.
  • Data from existing research were gathered and synthesized.
  • Different approaches to managing surgical astigmatism were analyzed.

Main Results:

  • Various surgical and non-surgical options exist for managing post-keratoplasty astigmatism.
  • The literature provides data, though sometimes limited, on the efficacy of different treatments.
  • This collation allows for a comparative overview of available treatment modalities.

Conclusions:

  • Addressing post-operative astigmatism is essential for optimizing vision after corneal transplantation.
  • A range of management options are available, with varying levels of supporting evidence.
  • Further research may be needed in certain areas to fully elucidate the best treatment strategies.
