What type of pharmaceuticals should be avoided in a patient with a narrow angle in the anterior chamber?

• A. Antihistamines
• B. Mydriatics
• C. Topical anesthetics
• D. Corticosteroids

Answer: (B)

In a patient with a narrow angle in the anterior chamber, mydriatics should be avoided because these medications dilate the pupil. This dilation can exacerbate or trigger an acute angle-closure glaucoma episode. In narrow-angle conditions, the iris can block the drainage angle of the eye, which is critical for maintaining proper intraocular pressure. When the pupil is dilated by mydriatic agents, it can further narrow the angle and hinder fluid drainage, potentially leading to increased pressure in the eye, pain, and vision loss. Antihistamines, topical anesthetics, and corticosteroids do not have the same effect on pupil dilation and are generally safer in patients with this condition. Therefore, avoiding mydriatics is essential to prevent complications associated with narrow-angle glaucoma.
