Microscope Solutions for Glaucoma Surgery

Glaucoma is one of the leading causes of irreversible blindness. This ocular disease increases eye pressure, causing damage to the optic nerve. According to the World Health Organization (WHO), 64 million people globally have glaucoma, with 6.9 million suffering from moderate to severe distance vision impairment or blindness as a result. The glaucoma patient population is expected to grow to 95.4 million in 20301.

Eye drops and laser treatment may help treat glaucoma. In some cases, glaucoma surgery may be indicated to lower the intraocular pressure and slow down progression of the disease. There are three main types of glaucoma surgery: trabeculectomy, glaucoma implant surgery and minimally invasive glaucoma surgery (MIGS).

Glaucoma Surgery Challenges

Glaucoma surgery disrupts the integrity of the eyeball, which can cause various complications. It is important to prevent these complications during surgery to obtain the best outcomes.

Some of the biggest challenges for glaucoma surgeons include:

  • Clearly visualizing the anterior chamber angle and anatomic landmarks in the structures
  • Achieving adequate scleral flap depth and thickness during dissection
  • Ensuring proper placement of devices
  • Creating a successful bleb
  • Avoiding tears or buttonholes in the conjunctiva and Tenon’s capsule

Glaucoma Microsurgery: Angle-Based and Canal-Based Glaucoma Surgeries

Micro-invasive or minimally invasive glaucoma surgery (MIGS) offers numerous benefits including minimal tissue disruption, ab-interno implantation, short surgical time, simple instrumentation, and fast postoperative recovery.

In angle-based and canal-based glaucoma surgeries, Leica microscopy solutions provide an optimal view of the angle, which supports proper placement of devices.

In addition, intraoperative Optical Coherence Tomography can support the visualization of intra-operative structures, facilitating precise microcatheter passage through the Schlemm’s canal.

Microscope Solutions for Glaucoma Surgery: Subconjunctival Stent Revision

Minimally invasive glaucoma surgery (MIGS) relies on the use of microstents, which can lower intraocular pressure through subconjunctival drainage. In some cases, these subconjunctival stents can fail, requiring stent revision surgery. The use of intraoperative Optical Coherence Tomography can provide valuable insights during these procedures. It can help assess whether the stent is embedded in the tenons layer.
