Can I apply warm compresses to the eyes for glaucoma?

In general, patients with glaucoma are usually not advised to apply warm compresses to the eyes, especially during acute attacks when this practice should be strictly avoided. During the chronic stable phase, warm compresses may be cautiously attempted only under a doctor's guidance.

During an acute glaucoma attack, intraocular pressure (IOP) can rapidly rise above 40 mmHg. Applying heat may dilate ocular blood vessels, increase aqueous humor production, and hinder its drainage, further elevating IOP. Patients with angle-closure glaucoma face even higher risks, as warm compresses may trigger an acute angle-closure glaucoma attack, causing severe eye pain, headache, nausea, vomiting, and potentially permanent optic nerve damage.

During the chronic stable phase, moderate warm compresses under medical supervision may help improve periorbital circulation and relieve eye fatigue, which could benefit some patients with open-angle glaucoma or those with angle-closure glaucoma who have stable IOP. However, prolonged or excessive warm compresses may still indirectly elevate IOP through vasodilation or cause IOP fluctuations due to temperature changes.

It is recommended that patients consult a qualified ophthalmologist before undertaking any self-care measures and follow their professional guidance to ensure the safety and effectiveness of treatment. In daily life, maintaining healthy lifestyle habits, undergoing regular eye examinations, and timely adjustment of treatment plans are key to managing glaucoma effectively.
