Question
My vision is blurry and I can’t see clearly. The doctor says it’s glaucoma. What causes glaucoma?
Answer
Glaucoma can be classified into primary and secondary types based on its cause. In primary glaucoma, individuals often have anatomical factors such as a small eye, a short eye axis, myopia, or shallow anterior chambers. Factors such as emotional stress, spending too much time in dimly lit areas, or prolonged periods of reading can trigger an attack. Severe cases can lead to an acute exacerbation, which, if not treated in time, can result in permanent blindness. Secondary glaucoma is often caused by trauma, inflammation, bleeding, or tumors that damage the drainage angle structure, leading to increased intraocular pressure due to impaired fluid drainage. In summary, glaucoma is caused by the inability of the fluid inside the eye to drain normally.
