What procedure is performed once the cornea clears during AACG management?

• A. YAG laser trabeculoplasty
• B. Laser peripheral iridotomy
• C. Phacoemulsification cataract extraction
• D. Vitrectomy

Answer: (B)

After the cornea clears, the next step is laser peripheral iridotomy. This creates a tiny hole in the peripheral iris, allowing aqueous humor to flow from the posterior to the anterior chamber. By equalizing pressure and opening the channel behind the iris, it relieves pupillary block and helps prevent future angle-closure attacks. Other options don’t address the pupillary block mechanism: YAG laser trabeculoplasty targets open-angle glaucoma outflow pathways, cataract extraction isn’t the standard preventive step for AACG unless lens factors are contributing, and vitrectomy isn’t relevant here.
