Patient's question:
Blurred vision, unable to see clearly, the doctor said it was glaucoma. What causes glaucoma?Doctor's answer:
Glaucoma can be divided into two major categories based on its cause: primary glaucoma and secondary glaucoma. Patients with primary glaucoma generally have anatomical factors, such as a small eye, short axial length, hyperopia, and shallow anterior chamber. Emotional fluctuations, prolonged stays in dimly lit areas, or prolonged reading while bending the head down may trigger glaucoma. In severe cases, it can lead to acute attacks, and if not treated promptly, it may result in permanent blindness. Secondary glaucoma is often caused by trauma, inflammation, bleeding, tumors, etc., which damage the structure of the anterior chamber angle, obstructing the outflow of aqueous humor and leading to elevated intraocular pressure. In summary, glaucoma is caused by the inability of the aqueous humor generated within the eye to drain normally.
