What are the causes of blurriness in glaucoma?

Multiple: Glaucoma can cause blurriness if the eye pressure is suddenly very high, which induces corneal swelling and haze. Advanced glaucoma can affect contrast sensitivity, visual acuity, and peripheral/eventually central vision. Glaucoma can coexist with other eye problems causing blurriness.

Several factors: The major cause of blurred vision from glaucoma is related to damage to the optic nerve. The visual information it sends to the brain is not as crisp since some of the "wires" within the nerve are lost. It is similar to a television cable that has been paritally cut, causing the t.V. Image to be less sharp.

Multiple reasons : Direct field of vision loss is a common cause . However in narrow angle glaucoma blurriness is a medical emergency and needs immediate attention . Glaucoma also causes contrast sensitivity loss.

Advanced disease: Glaucoma patients require eye lense power measurement like anyone else and eyeglass needs are common for this group. If that does not work then the blur might be due to damage from the disease which affects the nerves at the back of the eye causing gradual loss of vision over time if treatment is not GI ven properly.
