Summary
Gonioscopy-Assisted Transluminal Trabeculotomy (GATT) is a safe and effective minimally invasive glaucoma surgery. It reduces intraocular pressure and medication needs with fewer complications than traditional methods.
Area of Science:
- Ophthalmology
- Surgical Innovation
Background:
- Open-angle glaucoma management requires effective and safe surgical interventions.
- Traditional glaucoma surgeries often carry significant risks and complications.
Approach:
- Systematic literature review of Gonioscopy-Assisted Transluminal Trabeculotomy (GATT) procedures.
- Analysis of surgical technique, safety, and efficacy data from multiple studies.
Key Points:
- GATT effectively reduces intraocular pressure and the need for glaucoma medications.
- This ab-interno procedure offers a favorable safety profile with minimal complications compared to ab-externo techniques.
- GATT demonstrates a shorter learning curve and is suitable for primary surgical intervention in moderate to severe open-angle glaucomas.
Conclusions:
- Gonioscopy-Assisted Transluminal Trabeculotomy is a minimally invasive option for adult and pediatric open-angle glaucoma.
- Its advantages include an ab-interno approach, access to the entire natural drainage system, and efficacy comparable to trabeculectomy.
- Suture-based GATT is a cost-effective alternative, particularly beneficial for developing nations.

01:27Open Angle Glaucoma: Treatment
542
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.

01:28Angle Closure Glaucoma: Treatment
648
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...

01:25Glaucoma: Overview
721
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...
