In case you find any such symptoms, then you might be prone to have glaucoma sooner or later.
People with glaucoma often don’t realize that they might end up losing their peripheral vision, as they don’t notice the early signs. By the time they get warned of the disease, the vision problem might have advanced to dangerous levels. Symptoms of tunnel vision are not very easy to notice. Hence it is necessary for people with glaucoma and those above 40 years of age, to go for regular eye check-ups.
People who notice the early signs of glaucoma should also get tested for their vision. Glaucoma runs in families and most commonly in the African-Americans.
Treatment of tunnel vision or peripheral vision loss:
The treatment of the tunnel vision depends on the cause. For example, if the cause of peripheral vision loss is glaucoma, and the condition is detected during the initial stages, then some preventive measures could be taken to avoid the permanent loss of peripheral vision.
The doctor might prescribe some eye drops to the patients with glaucoma to relieve the eye pressure and to avoid the attack. Hence, the permanent damage to the optic nerve can be prevented by taking the glaucoma medication on time. If glaucoma is left untreated, then it might result in the loss of peripheral vision.
Unfortunately if you have a permanent peripheral vision loss, there are no corrective measures such as eye lenses or eyeglasses. However, the eye specialist might use some prism-like device to increase your vision width. This is possible in only certain types of tunnel vision problems.
Some eye specialist might also provide you some eye gears and optical devices, which might help you to solve the mobility problems.
If you suffer from tunnel vision or glaucoma, you must immediately fix your appointment with an eye specialist to get yourself checked for your condition. A right diagnosis at a right time can save your eyesight.
