Summary
Ex-Press Mini Glaucoma Shunt implantation under a superficial scleral flap effectively lowers intraocular pressure and reduces medication needs for glaucoma patients. While generally safe, device-related complications require monitoring.
Area of Science:
- Ophthalmology
- Surgical Technology
- Glaucoma Management
Background:
- Primary open-angle glaucoma (POAG) and refractory glaucoma require effective surgical interventions.
- Minimally invasive glaucoma surgery (MIGS) offers potential benefits in intraocular pressure (IOP) management.
- The Ex-Press Mini Glaucoma Shunt is an implantable device designed to reduce IOP.
Purpose of the Study:
- To evaluate the efficacy and safety of Ex-Press Mini Glaucoma Shunt implantation under a superficial scleral flap.
- To assess the impact on postoperative intraocular pressure (IOP) and medication requirements.
- To identify early postoperative complications associated with this surgical technique.
Main Methods:
- Prospective study involving 44 eyes (35 patients) with POAG and pseudoexfoliation glaucoma (PEXG).
- Ex-Press Mini Glaucoma Shunt implantation performed under a superficial scleral flap.
- Postoperative IOP measurements at multiple time points (1 day to 12 months); assessment of medication use and complications.
Main Results:
- Mean IOP reduced by 52.8% at 1 year postoperatively compared to preoperative values.
- Postoperative medication use decreased by 77% compared to preoperative levels.
- Early complications included hypotony (3.5%), choroidal ablation (7%), intraocular hemorrhage (3.5%), and shunt closure (3.5%).
Conclusions:
- Ex-Press Mini Glaucoma Shunt implantation under a superficial scleral flap is a safe and effective procedure for glaucoma.
- The surgery provides satisfactory IOP control and significant reduction in medication needs.
- Device-related complications necessitate careful patient selection and postoperative monitoring.

01:28Angle Closure Glaucoma: Treatment
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...
01:27Open Angle Glaucoma: Treatment
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.

01:25Glaucoma: Overview
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...
