Angle Closure Glaucoma: Treatment

Angle 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...

Open Angle Glaucoma: Treatment

Open 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.
Drugs such as carbonic anhydrase inhibitors, α2- and...

Summary

This summary is machine-generated.

Boston keratoprosthesis (KPro) surgery can lead to angle closure glaucoma. Careful monitoring is essential post-KPro to detect progressive angle closure, especially when irido-backplate touch occurs.

Background:

The Boston keratoprosthesis (KPro) is a vital treatment for corneal blindness.
Understanding the impact of KPro on anterior segment anatomy is crucial for patient management.

Purpose of the Study:

To evaluate changes in the anterior chamber angle following Boston KPro implantation.
To identify potential risk factors for angle closure post-KPro surgery.

Main Methods:

Serial anterior segment optical coherence tomography (AS-OCT) imaging was performed on 10 patients post-Boston KPro surgery.
Anterior chamber angles were assessed for patency (open or closed) in the horizontal axis.

Main Results:

Pre-operatively, 70% of patients had open angles.
Within 4 months, 40% of patients developed angle closure, with 30% showing irido-backplate touch.
Elevated intraocular pressure (IOP) occurred in 30% of patients due to angle closure or glaucoma drainage device obstruction.

Conclusions:

Boston KPro placement can precipitate or worsen angle closure glaucoma.
Progressive angle closure and irido-backplate touch are potential complications requiring vigilant monitoring.
Regular IOP assessment and anterior segment evaluation are critical for glaucoma management after KPro surgery.
