Glaucoma: Overview

949
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...

Angle Closure Glaucoma: Treatment

879
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...

Area of Science:

  • Ophthalmology
  • Surgical Techniques

Background:

  • Penetrating keratoplasty can lead to expulsive suprachoroidal hemorrhage, a severe complication.
  • This video addresses the prevention and management of this rare surgical challenge.

Purpose of the Study:

  • To educate corneal surgeons on recognizing and managing expulsive suprachoroidal hemorrhage.
  • To demonstrate real-time surgical video of this complication and its mitigation.

Main Methods:

  • The video showcases a case of expulsive choroidal hemorrhage during autokeratoplasty.
  • Management involved using a glycerin-preserved donor corneal button.

Main Results:

  • The complication occurred in a non-seeing eye during autokeratoplasty.
  • The described management approach was utilized.

Conclusions:

  • Expulsive choroidal hemorrhage requires mental preparedness and specific management strategies.
  • Pre-operative risk factor management and intra-operative maneuvers are crucial for prevention and damage mitigation.
