How high is the rate of blindness caused by glaucoma?

Patient's question:

My husband is 37 years old. He has glaucoma in his left eye for six years. Treatment history and effectiveness: He has undergone many surgeries, and the condition has been kept under control. What kind of help is needed: I would like to ask, at the age of 37, what is the probability of him losing hearing, and what is the probability of the condition spreading to the other eye? Thank you

Doctor's answer:

Glaucoma is an eye disease that can cause damage to the optic nerve, even swelling, affecting visual function and ultimately leading to blindness. Timely treatment will never result in blindness. Once diagnosed with glaucoma, it is essential to seek treatment at a regular hospital and follow up regularly for careful observation. This is the only way to control the expansion of optic nerve damage, maintain valuable visual function, and prevent blindness.
In addition, patients should develop a good habit of regular routines, adhere to treatment, and maintain a light diet with aerobic exercise to boost their immunity and reduce the risk of the disease.
