What is usually recommended to decrease intraocular pressure in closed-angle glaucoma?

In closed-angle glaucoma, the primary concern is the rapid increase in intraocular pressure (IOP), which can lead to optic nerve damage and vision loss. To manage this condition effectively, medications that are specifically designed to lower intraocular pressure are recommended. These can include carbonic anhydrase inhibitors, beta-blockers, prostaglandin analogs, and alpha agonists, all of which work to reduce the production of aqueous humor or increase its outflow.

The use of these medications is critical in acute situations where IOP is significantly elevated, especially since timely intervention can prevent serious complications. Other options such as atropine treatment would be contraindicated because it can dilate the pupil, further worsening the angle closure. Reducing exposure to bright light and administering antihistamines do not address the underlying issue of raised IOP and, therefore, are not appropriate treatments in this specific context.
