Abstract: Glaucoma surgery plays a crucial role in the management of glaucoma, aiming to reduce intraocular pressure (IOP) and preserve vision. This article provides an extensive review of surgical interventions for glaucoma, exploring traditional techniques, minimally invasive procedures, and recent innovations. By examining the latest advancements in glaucoma surgery, ophthalmologists can enhance their understanding and improve patient outcomes.

Introduction: Glaucoma surgery has evolved significantly over the years, from traditional trabeculectomy to minimally invasive techniques such as microstent implantation and laser procedures. Understanding the various surgical options and their indications is essential for providing optimal care to patients with glaucoma.

Traditional Surgical Techniques:

1. Trabeculectomy: Trabeculectomy remains the gold standard for glaucoma surgery, creating a new drainage pathway to lower IOP.
   • Learn more about trabeculectomy from the American Academy of Ophthalmology: Trabeculectomy Information
2. Glaucoma Drainage Devices (GDDs): GDDs such as Ahmed and Baerveldt implants are effective in lowering IOP by diverting aqueous humor to an external reservoir.

Minimally Invasive Glaucoma Surgery (MIGS):

1. iStent and iStent inject: These microstents are implanted during cataract surgery to enhance aqueous outflow through the trabecular meshwork.

Recent Innovations:

1. Endoscopic Cyclophotocoagulation (ECP): ECP utilizes endoscopic visualization and laser therapy to reduce IOP by targeting the ciliary body.

Conclusion: Glaucoma surgery continues to evolve with advancements in technology and techniques, offering improved outcomes and reduced invasiveness for patients. By staying informed about the latest innovations in glaucoma surgery, ophthalmologists can provide state-of-the-art care to individuals with glaucoma, ultimately preserving vision and enhancing quality of life.
