Creates a hole in the iris of the eye?

• A. Laser Iridotomy
• B. Iridectomy
• C. Iridoplasty
• D. Iris Trephination

Answer: (A)

Creating a hole in the iris is done with Laser Iridotomy. This procedure uses a focused laser to make a tiny opening in the peripheral iris, usually near the pupil. That opening provides a new pathway for aqueous humor to move from the posterior chamber to the anterior chamber, bypassing a pupillary block that can lead to angle-closure glaucoma. It’s noninvasive and typically done on an outpatient basis, because it creates a hole without removing tissue. Other approaches involve removing iris tissue to form a hole (iridectomy), reshaping the iris with laser without making a hole (iridoplasty), or using a circular cutting method (iris trephination); these have different mechanisms and purposes, whereas laser iridotomy specifically creates the hole to equalize pressure and improve aqueous flow.
