What type of eye drops would a nurse likely administer to manage intraocular pressure in a patient with glaucoma?

• A. Antihistamine eye drops.
• B. Antibiotic eye drops.
• C. Beta-blocker eye drops.
• D. Moisturizing eye drops.

Answer: (C)

In managing intraocular pressure in patients with glaucoma, beta-blocker eye drops are commonly prescribed as they effectively reduce the production of aqueous humor, the fluid within the eye. This reduction directly lowers intraocular pressure, which is crucial in preventing damage to the optic nerve and preserving vision.

Beta-blockers, such as timolol, work by blocking the effects of adrenaline on the eye’s tissues, leading to decreased fluid production and, consequently, lower pressure. This therapeutic action makes them a first-line treatment option in the management of glaucoma.

The other types of eye drops mentioned serve different purposes. Antihistamine eye drops are primarily used to relieve allergy symptoms, antibiotic eye drops are intended to treat infections, and moisturizing eye drops aim to alleviate dry eyes. None of these options address the specific need to control intraocular pressure, which is why beta-blocker eye drops stand out as the appropriate choice for managing glaucoma.
