Patient's question:
My father had cataract surgery at North Hospital over 20 years ago. He is now 69 years old and only has vision of 0.25 in one eye, while the other eye is completely deaf. The eye that had the glaucoma surgery, with vision of 0.25, was tested for eye pressure on November 12th, and the results showed normal, not high. However, his vision is still only 0.25. Now, during the day, things seem hazy when he looks at them, and he is sensitive to light. It takes him several minutes to see clearly when he steps into a dark place. Sometimes, his eye may turn white for a few seconds, but it returns to normal shortly after.Doctor, do you think surgery is necessary in this case? If not, what kind of medicine could help improve his vision and reduce the hazy effect? What kind of medicine can control the progression of the condition? Will his vision worsen if he doesn’t have surgery? Thank you, Doctor. I look forward to your reply.
Doctor's answer:
According to your description of the condition, this is dark adaptation of the eye, which is generally a normal phenomenon. However, since the elderly have relatively poor vision, it is best to have a comprehensive eye examination at a formal hospital to rule out cataracts, retinal diseases, and other conditions. Generally speaking, if the vision loss is caused by glaucoma leading to optic nerve atrophy, there is currently no particularly effective treatment available, only regulation and prevention measures to prevent further vision deterioration.
