Abstract

Insights

This case report details malignant glaucoma after Preserflo™ MicroShunt implantation in primary open angle glaucoma. Management involved multiple interventions, including laser and surgery, to resolve the condition.

Area of Science:

  • Ophthalmology
  • Glaucoma Surgery

Background:

  • Primary open angle glaucoma (POAG) management often requires surgical intervention.
  • Preserflo™ MicroShunt (PMS) is a device used to lower intraocular pressure (IOP) in glaucoma patients.

Observation:

  • A 46-year-old male with medically uncontrolled POAG developed malignant glaucoma one day after PMS insertion.
  • The condition recurred multiple times despite various treatments, including laser iridotomy and revision surgery.

Findings:

  • Malignant glaucoma following PMS insertion can occur, potentially due to iris occlusion of the device in shallow anterior chambers.
  • Successful resolution was achieved with pars plana vitrectomy, clear lens extraction, and surgical irido-zonulo-hyaloidectomy.

Implications:

  • This case highlights the importance of recognizing and managing malignant glaucoma post-PMS implantation.
  • Treatment strategies may need to be tailored, considering the potential for device obstruction and recurrent episodes.

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...

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...

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.
