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...

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...

Focusing of Light in the Eye01:16

Focusing of Light in the Eye

7.4K
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
  • Biomedical Engineering
  • Optometry

Background:

  • Scleral lenses are large-diameter rigid gas permeable lenses that vault over the cornea, resting on the sclera.
  • They create a fluid-filled tear reservoir between the lens and the cornea, avoiding direct corneal contact.
  • Conventional contact lenses rest directly on the cornea, which can be problematic for certain ocular conditions.

Purpose of the Study:

  • To review recent advancements in scleral lens technology.
  • To highlight new designs, materials, manufacturing techniques, and fitting strategies.
  • To focus specifically on applications and improvements for keratoconus management.

Main Methods:

  • Literature review of recent developments in scleral lens technology.
  • Analysis of new materials and manufacturing processes.
  • Evaluation of updated fitting methodologies.

Main Results:

  • Significant innovations in scleral lens design and materials have emerged.
  • Advanced manufacturing technologies enable more precise and customized lens production.
  • Evolving fitting strategies enhance patient outcomes, particularly for complex corneal conditions.

Conclusions:

  • Scleral lenses represent a significant advancement in managing irregular astigmatism and ocular surface diseases.
  • Ongoing research and development continue to improve the efficacy and application of scleral lenses.
  • These lenses are crucial for patients with conditions like keratoconus, offering improved vision and comfort.
