7 Signs You May Have Glaucoma
5. Loss Of Side Or Peripheral Vision

Open-angle glaucoma does not have many warning signs or symptoms before permanent damage occurs. One of the first and only early signals is the loss of side or peripheral vision, which is a person’s field of vision on the side of the eye when looking straight ahead. Seek immediate treatment if side vision becomes blurred or starts losing its strength as this may be the only indication of early onset glaucoma. Ignoring these symptoms could lead to permanent vision loss.
4. Severe Eye Or Head Pain

Headaches can appear for no reason at all; however, eye pain could be an indication of glaucoma. When both appear at the same time, seek immediate medical help. Fluid retention in the eye may cause pressure that eventually leads to pain. Even if vision loss has not occurred yet, eye pain should be checked out immediately to avoid irreversible damage. Even eye pain that does not affect vision may also cause a headache due to the inability or strain on the eyes to focus.
