Certain medications can trigger or worsen angle-closure glaucoma by causing pupil dilation or fluid buildup. These include drugs with anticholinergic or adrenergic effects. People with narrow angles should be cautious and consult their doctor before starting new medications. Awareness helps prevent sudden pressure spikes and vision risk.

Common examples include decongestants, antidepressants, and antihistamines. Topical or systemic agents should be reviewed before use. Screening identifies at-risk eyes before exposure.
Decongestants, certain antidepressants, and motion sickness medications can dilate pupils. These effects may narrow the angle in susceptible individuals. Over-the-counter remedies can also pose risk. Checking with a doctor before use is advised.
Many act on the autonomic nervous system, influencing pupil size and fluid dynamics. Pupil dilation can block fluid drainage through the trabecular meshwork. The resulting pressure rise can become dangerous if unrecognized. Monitoring prevents complications.
Eye exams can identify narrow angles early. Doctors may perform preventive laser iridotomy if risk is high. Informing all healthcare providers about glaucoma status reduces exposure. Education supports safe medication choices.
Stop using the suspected medication and seek medical help immediately. Symptoms like pain, halos, and blurred vision indicate high pressure. Rapid treatment can reverse pressure elevation. Follow-up ensures stability.
Acute angle-closure glaucoma occurs when the iris suddenly blocks the eye's drainage angle, preventing aqueous humor from exiting and causing a rapid rise in pressure. Triggers can include pupil dilation in a naturally narrow angle, stress or certain medications.
Symptoms may include severe eye pain, headache, blurred vision, halos around lights, nausea and vomiting. The eye may appear red and the pupil may be mid-dilated and non-reactive.
Treatment is urgent and involves lowering intraocular pressure with medications, followed by laser or surgical procedures such as laser peripheral iridotomy to create an opening that restores fluid flow.
