**Core Concept**
Argon Laser Trabeculoplasty (ALT) is a surgical procedure used to treat **glaucoma** by enhancing aqueous outflow. It targets the **trabecular meshwork**, a spongy tissue near the base of the iris. This procedure aims to reduce **intraocular pressure**.
**Why the Correct Answer is Right**
The correct answer is related to the treatment of glaucoma, specifically **open-angle glaucoma**. ALT works by creating small burns in the trabecular meshwork, which helps to increase the outflow of aqueous humor, thus reducing intraocular pressure. This is achieved through the use of an **argon laser**.
