Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

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: Treatment01:28

Angle Closure Glaucoma: Treatment

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

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...

Area of Science:

  • Ophthalmology
  • Surgical Techniques

Background:

  • Pupillary block can occur due to iris adhesion to a continuous circular capsulorhexis.
  • Management of such cases requires effective peripheral iridectomy.

Observation:

  • A 25-gauge vitreous cutter was utilized for peripheral iridectomy in the anterior chamber.
  • The fine shaft allowed easy insertion and manipulation without corneal endothelial contact, even in shallow anterior chambers.

Findings:

  • The 25-gauge vitreous cutter facilitated a simple and precise peripheral iridectomy at the desired location.
  • Successful resolution of pupillary block and control of intraocular pressure were achieved post-procedure.

Implications:

  • This technique provides a straightforward method for performing peripheral iridectomies.
  • It offers a safe and effective option for managing pupillary block in specific ophthalmic conditions.
