Glaucoma: Overview01:25

Glaucoma: Overview

499
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: Treatment01:28

Angle Closure Glaucoma: Treatment

433
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

390
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...

Summary
This summary is machine-generated.

Minimally invasive glaucoma surgery (MIGS) can lead to serious complications, including vision loss, despite its minimally invasive nature. Surgeons must remain vigilant for potential issues during and after stent-less MIGS procedures.

Area of Science:

  • Ophthalmology
  • Glaucoma Surgery
  • Surgical Complications

Background:

  • Minimally invasive glaucoma surgery (MIGS) offers a less invasive approach to managing glaucoma.
  • Stent-less MIGS procedures, including gonioscopy-assisted transluminal trabeculotomy (GATT), bent needle goniectomy (BANG), Kahook-dual blade goniotomy, and microincisional trabeculectomy (MIT), are increasingly utilized.
  • Understanding potential complications is crucial for patient safety and surgical planning.

Purpose of the Study:

  • To comprehensively review and discuss the various complications associated with stent-less incisional or excisional MIGS procedures.
  • To highlight potential intraoperative and postoperative adverse events.
  • To emphasize the importance of vigilance in managing these procedures.

Main Methods:

  • A systematic review of published literature on stent-less MIGS complications.
  • Analysis of reported complications from 2014 to 2024.
  • Inclusion of procedures such as GATT, BANG, Kahook-dual blade goniotomy, and MIT.

Main Results:

  • Common complications include hyphema, peripheral anterior synechiae, and intraocular pressure spikes.
  • Vision-threatening complications such as cyclodialysis, Descemet's detachment, corneal edema, iridodialysis, vitreous loss, and vitreous hemorrhage can occur.
  • These complications may arise during or after incisional or excisional MIGS.

Conclusions:

  • Despite being minimally invasive, stent-less MIGS procedures carry risks of significant complications.
  • Awareness of all potential adverse events is essential for surgeons.
  • Careful surgical technique and management throughout all stages are necessary to mitigate risks and ensure optimal patient outcomes.
