Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

1.1K
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: Overview

1.2K
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...

Open Angle Glaucoma: Treatment

908
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...

Area of Science:

  • Ophthalmology
  • Ophthalmic Surgery

Background:

  • Intraocular lens (IOL) implantation in the ciliary sulcus is considered when the capsular bag is inadequate.
  • The ophthalmic industry is actively developing specialized IOLs for sulcus placement.
  • Understanding ciliary sulcus anatomy is key for successful implantation.

Purpose of the Study:

  • To review the risks and challenges of intraocular lens (IOL) implantation in the ciliary sulcus.
  • To evaluate current literature on IOLs suitable for ciliary sulcus placement.

Main Methods:

  • Literature review of current research on ciliary sulcus IOL implantation.
  • Analysis of complications associated with different IOL types in the sulcus.
  • Examination of imaging techniques for ciliary sulcus assessment.

Main Results:

  • One-piece polymethylmethacrylate (PMMA) and three-piece IOLs are currently suitable for ciliary sulcus placement.
  • Single-piece acrylic (SPA) IOLs are not designed for sulcus placement and are associated with chronic complications.
  • Complications may necessitate further surgical intervention, such as lens exchange.

Conclusions:

  • Ciliary sulcus IOL placement is a reasonable alternative when the capsular bag is compromised.
  • Appropriate IOL selection, anatomical knowledge, and surgical technique are essential for optimal outcomes.
  • Minimizing postoperative complications relies on careful management of sulcus IOL implantation.
