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
  • Surgical Innovation
  • Medical Device Technology

Background:

  • Complex vitreoretinal diseases often pose surgical challenges.
  • Custom flexible iris prosthesis (CFIP) offers a potential solution for improved visualization during ocular surgery.

Purpose of the Study:

  • To evaluate the outcomes of pars plana vitrectomy in patients who received a custom flexible iris prosthesis (CFIP).
  • To assess the safety and efficacy of CFIP during vitreoretinal surgery.

Main Methods:

  • Retrospective review of medical records for patients undergoing CFIP placement and pars plana vitrectomy.
  • Analysis of preoperative, intraoperative, and postoperative data, including visual acuity and complications.
  • Surgeon surveys on visualization ease through the CFIP pseudopupil.

Main Results:

  • Twenty-four surgeries in 20 eyes showed 100% short-term anatomical success.
  • Postoperative visual acuity improved in 55% of eyes; complications occurred in 25% of eyes.
  • No intraoperative complications were reported, and visualization through CFIP was deemed viable.

Conclusions:

  • Pars plana vitrectomy with CFIP assistance is a viable surgical approach for complex vitreoretinal diseases.
  • The CFIP's pseudopupil allows adequate visualization for both direct and wide-angle viewing systems.
