The atrial angle is the angle between the iris and the cornea. Stenosis of the atrial angle can lead to elevated intraocular pressure in the patient and may also lead to glaucoma. The atrial angle is an important part of the aqueous humor circulation pathway. Aqueous humor passes through the trabecular meshwork of the anterior atrial angle and enters the aqueous humor vein and then converges into the preciliary vein, allowing the aqueous humor to return to the blood circulation to complete the aqueous humor cycle. When the stenosis of the atrial angle occurs, the return of aqueous humor is impeded, and the aqueous humor cannot return to the eye, resulting in increased intraocular pressure, which can induce severe headache, eye pain, photophobia, tearing, vision loss and other glaucoma symptoms. Patients with atrial angle stenosis can use Hirschsprung’s Eye Drops and Betaxolol Eye Drops to regulate the contraction of the iris, which can help to reduce the stenosis of the anterior chamber angle and increase the outflow of aqueous humor, thus lowering the intraocular pressure. It is recommended that patients with atrial angle stenosis who experience eye discomfort should consult a hospital in a timely manner to assess their condition and undergo regular treatment under the guidance of a doctor.
