6. Increased Visual Disturbance
As we age, it is normal for vision loss to slowly deteriorate. Increased visual disturbances can range from flashes, sharp stinging sensations, or long bouts of unfocused vision. The disturbances can occur in one or both eyes, and can vary from bright flashes to floating circles or squiggly lines in the field of vision. These problems with the vision will be more typical at night in conditions of low lighting.
7. Tunnel Vision
Primary open-angle glaucoma symptoms begin with the narrowing of the peripheral vision. As the sight begins to narrow, it appears that the patient is looking through a tunnel, hence the name tunnel vision. As the condition gets worse, the edges of field of vision for both eyes will deteriorate. If you are not paying close attention , you might not realize that there is a concern until the only thing you can see is directly in front of you. By this point you have reached the advanced stages of glaucoma. Periodic eye exams will be instrumental in detecting issues with your field of vision.
8. Changes in the Eye
During the early stages of glaucoma, it is very challenging to see the damage with your naked eye. Those who are suffering with acute angle-closure glaucoma will begin to see that their pupils appear larger and the eyeball itself has turned a light shade of red. Take a flashlight and shine it into the eye to see if the pupils respond by shrinking, then enlarging. Glaucoma will cause the pupil to become non-responsive to the direct light. The transparent eye covering, known as the cornea, will also appear swollen and cloudy as glaucoma begins to damage the eye.
Glaucoma is challenging to detect without the understanding of these symptoms. This is one of the reasons that this disease is often referred to in the medical world as “the sneak thief of vision.” For that reason, the best thing that you can do to catch this disease early is to have an annual eye exam with your local eye specialist.
