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...

Glaucoma: Overview

1.6K
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

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...

Area of Science:

  • Ophthalmology
  • Corneal Science
  • Cataract Surgery

Background:

  • Cataract surgery can impact corneal endothelial cell density.
  • Understanding factors that protect corneal endothelium is crucial.

Purpose of the Study:

  • To assess if preoperative mannitolization alters ocular biometry.
  • To determine its effect on postoperative corneal endothelial cell density.

Main Methods:

  • Bilateral sequential cataract surgery in 38 patients.
  • Preoperative mannitolization applied to one eye per patient.
  • Comparison of ocular biometry and corneal endothelial cell density between mannitolized and non-mannitolized eyes.

Main Results:

  • Mannitolization decreased intraocular pressure, axial length, and vitreous chamber depth, while increasing anterior chamber depth and lens position.
  • Eyes with mannitolization showed significantly less loss of corneal endothelial cells post-surgery.
  • Changes in anterior chamber depth, lens position, and axial length correlated with reduced corneal endothelial cell loss.

Conclusions:

  • Preoperative mannitolization reduces postoperative corneal endothelial cell loss.
  • This protective effect may stem from altered ocular biometry and reduced phaco energy requirements.
