Summary
Imaging techniques can visualize aqueous humor outflow (AHO) to improve patient selection and surgical outcomes in angle-based minimally invasive glaucoma surgery (MIGS). This review highlights the potential of AHO visualization for enhancing MIGS efficacy.
Area of Science:
- Ophthalmology
- Medical Imaging
- Glaucoma Surgery
Background:
- Angle-based minimally invasive glaucoma surgery (MIGS) adoption is increasing, but limitations persist.
- Imaging techniques offer potential for patient selection and outcome improvement across MIGS stages.
- This review focuses on imaging for visualizing aqueous humor outflow (AHO) in angle-based MIGS.
Conclusions:
- Imaging techniques visualizing AHO hold significant potential for improving angle-based MIGS outcomes.
- AHO visualization can enhance patient selection, surgical prognostication, and targeted MIGS placement.
- Comparative analysis of MIGS efficacy is facilitated by pre-, intra-, and post-operative AHO assessment.

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.

01:28Angle 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...
01:25Glaucoma: 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...
