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...

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...

Area of Science:

  • Ophthalmology
  • Refractive Surgery

Background:

  • Astigmatism is a common refractive error, often requiring correction during cataract surgery.
  • Toric intraocular lenses (IOLs) are the established standard for managing astigmatism in this patient population.

Purpose of the Study:

  • To synthesize current evidence on toric IOLs for astigmatism correction in cataract surgery.
  • To review clinical indications, surgical outcomes, and emerging technologies related to toric IOLs.

Main Methods:

  • A narrative review of systematic reviews and meta-analyses was conducted.
  • Searched multiple databases (MEDLINE, Embase, Cochrane Library, etc.) up to June 2025.
  • Included reviews, meta-analyses, and clinical guidelines on toric IOLs.

Main Results:

  • Eighty-five reviews were analyzed, covering astigmatism prevalence, toric IOL technology, and surgical aspects.
  • Key outcomes included rotational stability, surgically induced astigmatism, and patient-reported outcomes.
  • Discussed reporting standards, adverse events, and special populations.

Conclusions:

  • Toric IOLs significantly improve visual acuity and refractive outcomes in cataract patients with astigmatism.
  • Advancements in diagnostics, lens design, and surgical tools enhance accuracy and satisfaction.
  • Further research is recommended to address knowledge gaps and optimize clinical practices.
