by Matthew LaBrier Glaucoma refers to a group of eye conditions
that lead to damage of the optic nerve.The optic nerve carries
visual information from the eye to the brain. Glaucoma is the
second leading cause of blindness behind Cataracts. There are
four main types of Glaucoma: Open-Angle (Chronic) Glaucoma: The
cause is unknown. Pressure in the eyes increases over time,
pushing on the optic nerve and retina. Many people live symptom
free for years and don't realize they're affected until they
begin to lose vision. People of African descent are at
particularly high risk. Symptoms include: Gradual loss of
peripheral vision, also known as "tunnel vision" Angle-Closure
(Acute) Glaucoma: Emergency situation that comes on rapidly.
Sudden and severe rise in intraocular pressure in one eye. Can
be triggered by certain medications and dilating eye drops.
Symptoms include: cloudy vision, red eye, nausea and vomiting.
Present from birth. Symptoms are often noticed within months of
