Vision Disorders

Acute Glaucoma

Acute glaucoma may happen in a matter of hours and causes very fast vision loss, severe pain, and a bloodshot and watery eye. Colored haloes around lights may be visible prior to onset. It primarily affects one eye at a time, usually begins in the evening, and often after a physical or emotional trauma. It is most common in people over the age of 40 years, particularly in the 60-70 year age group. Immediate medical intervention is imperative to prevent damage to the optic nerve and subsequent blindness.
