Procedures
Glaucoma is a condition in which the optic nerve gradually becomes thinner. Information from the affected part of the retina cannot be transmitted to the brain, causing shadows in your vision. If the shadow reaches the central part of vision, your vision will become blurred.

Visual Field Loss
It can be difficult to diagnose glaucoma and many visits may be needed to confirm the condition, especially in early stages. Gradual thinning of the optic nerve or characteristic visual field defects confirm the diagnosis.
Visual field test maps the field of vision, showing areas of reduced sensitivity. OCT scan measures the thickness of the nerve layer. Progressive thinning may confirm the diagnosis of glaucoma even without visual field defects.

Treatment of Glaucoma
Most patients with glaucoma are adequately managed with eyedrops to lower the eye pressure. If eyedrops are not sufficient, laser therapy or various drainage surgeries can be performed to reduce the eye pressure. Acute glaucoma must be treated as an emergency.
