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...

Angle Closure Glaucoma: Treatment

1.7K
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...

Glaucoma: Overview01:25

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...

Ophthalmic Drug Delivery Systems

244
Ophthalmic drug delivery faces major limitations due to poor absorption across the corneal membrane. This process is primarily driven by diffusion and is influenced by two main factors: the physicochemical properties of the drug and tear drainage. Most ophthalmic drugs, such as pilocarpine, epinephrine, atropine, and local anesthetics, are weak bases. They are typically formulated at an acidic pH to enhance chemical stability. However, this leads to high ionization, reducing their ability to...

Area of Science:

  • Ophthalmology
  • Biomaterials Science
  • Regenerative Medicine

Background:

  • The natural vitreous body possesses intricate structure and vital functions.
  • Current vitreous substitutes like gases and silicone oils have limitations and complications.
  • Existing substitutes lack the structural and functional complexity of the natural vitreous.

Purpose of the Study:

  • To review the current status and challenges in developing artificial vitreous substitutes.
  • To explore future directions in vitreous substitute research.
  • To highlight the experimental and clinical use of a novel artificial foldable capsular vitreous body.

Main Methods:

  • Review of existing literature on vitreous substitutes.
  • Analysis of clinical applications and complications of current substitutes.
  • Evaluation of a new artificial foldable capsular vitreous body.

Main Results:

  • Gases, silicone oil, heavy silicone oil, and hydrogels are commonly used but imperfect vitreous substitutes.
  • These materials do not replicate the natural vitreous body's structure or function.
  • The new artificial foldable capsular vitreous body represents a step towards a more functional substitute.

Conclusions:

  • Significant challenges persist in creating artificial vitreous that matches natural vitreous body properties.
  • Further research is needed to overcome limitations of current vitreous substitutes.
  • The artificial foldable capsular vitreous body offers a promising avenue for future vitreous replacement.
