The cause of glaucoma is not fully understood, and is currently believed to be related to genetic, developmental abnormalities, secondary factors and other causes; elevated intraocular pressure is a risk factor. 1. Genetic factors: some glaucoma has a certain genetic predisposition; if there is a family history of glaucoma, the incidence rate will be higher than normal. 2. Developmental abnormality: abnormal development of the atrial angle will lead to the dysfunction of aqueous drainage, which will result in the elevation of intraocular pressure, thus triggering glaucoma. 3. Secondary factors: eye surgery, diabetes, blood diseases, cardiovascular diseases, frequent use of corticosteroids, etc. may induce glaucoma. There are many reasons for the formation of glaucoma, when you find the disease, you should seek medical treatment in time for standardized treatment, so as not to damage your eye health and cause irreversible consequences.
