Malignant glaucoma can occur after laser iridotomy, a procedure thought to prevent it. While medical therapy is often effective, malignant glaucoma can recur or affect the fellow eye.

Area of Science:

  • Ophthalmology
  • Glaucoma Research
  • Surgical Complications

Background:

  • Malignant glaucoma (MG) is a severe form of secondary angle-closure glaucoma.
  • Historically, MG was associated with glaucoma surgery, trauma, inflammation, or miotic agents.
  • Laser iridotomy was believed to mitigate MG risk in angle-closure glaucoma by avoiding surgical incisions.

Observation:

  • This study reports six cases of malignant glaucoma (MG) developing after laser iridotomy.
  • Laser iridotomy is a common procedure for angle-closure glaucoma, intended to prevent complications.
  • The occurrence of MG post-laser iridotomy challenges previous assumptions.

Findings:

  • Medical therapy successfully deepened the anterior chamber and normalized intraocular pressure in most cases.

  • Recurrence of malignant glaucoma was observed in five out of six patients.
  • Two patients experienced malignant glaucoma in their fellow eye, indicating a potential bilateral predisposition.

    • Implications:

    • Laser iridotomy does not eliminate the risk of malignant glaucoma in susceptible individuals.
    • Close monitoring for malignant glaucoma is crucial even after laser iridotomy.
    • Further research is needed to understand the mechanisms and identify risk factors for post-laser iridotomy malignant glaucoma.
