One of the primary reasons behind this disease is damaging the optic nerve. With a gradual deterioration in the optic nerve, blind spots start developing in the visual field. Nerve damage is closely related to increased eye pressure. Ultimately, when there is hypertension, pressure becomes higher than normal, and leads to glaucoma. Other than this, symptoms like blocked blood vessels in the eye, eye injury, inflammatory conditions, and severe eye infection can also lead to glaucoma.
