Summary
Conjunctival erosion is a rare complication after PRESERFLO® MicroShunt surgery. Revision surgery may be needed, and careful technique during bleb needling is crucial to prevent this issue.
Area of Science:
- Ophthalmology
- Glaucoma Surgery
- Ophthalmic Implants
Background:
- The PRESERFLO® MicroShunt is a device used in glaucoma surgery to reduce intraocular pressure.
- Conjunctival erosion is a potential complication associated with subconjunctival implants.
Observation:
- A case of conjunctival erosion overlying a PRESERFLO® MicroShunt implant is presented.
- Erosion occurred 11 weeks postoperatively, 8 weeks after a bleb needling procedure for encapsulation.
- A significant leak was noted at the erosion site.
Findings:
- The patient underwent revision surgery involving MicroShunt repositioning and mitomycin C (MMC) application.
- Conjunctival erosion, while rare, is an important complication of MicroShunt surgery.
Implications:
- Careful technique during bleb needling is essential to avoid damaging the MicroShunt implant.
- Needling should be directed posteriorly, away from the distal tip of the MicroShunt, to minimize erosion risk.

01:28Angle Closure Glaucoma: Treatment
864
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
938
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...
