Glaucoma is disease of the optic nerve involving loss
of retinal ganglion cells in a characteristic pattern
of optic neuropathy. This may be due to unstable blood
Glaucoma is one of the leading causes of blindness
in the U.S. It most often occurs in people over age
40. It affects one in 200 people under age 50, and one
in 10 over the age of eighty.
Genetics appear to play a part in the propensity to
develop glaucoma, with the chance of developing glaucoma
increasing to six percent for those with a family history
In addition, diabetics and those of African-American
descent are three times more likely to develop primary
open angle glaucoma.
Cause of Glaucoma
One of the main pre-conditions to developing glaucoma
is elevated intraocular pressure; howevver, there is
no set threshold for intraocular pressure that causes
One person may develop nerve damage at a relatively
low pressure, whilst another person may have high eye
pressure for many years without any symptoms or any
damage to the eye.
Leaving glaucoma untreated can lead to permanent damage
of the optic nerve and resul in loss of visual field
and can even lead to blindness.
Symptoms & Diagnosis
Screening for glaucoma is part of the standard eye
examination performed by ophthalmologists and optometrists.
It is tested using a combination of intraocular pressure
via tonometry, changes in size or shape of the eye,
and an examination of the optic nerve for any visible
damage and/or a change in the cup-to-disc ratio.
If there are any indications of glaucoma, a fulll visual
field test is performed. In addition, a laser ophthalmoscope
scan may also be performed.
Prevention & Treatment
Glaucoma cannot be prevented, nor can vision lost to
glaucoma be restored. It is therefore essential that
annual eye examinations are done so that glaucoma can
be diagnosed as early as possible.
Although there is as yet no cure for glaucoma, it
can be treated with either medications or surgery.
Supplements - certain nutritional
elements that are known to help prevent the onset of
glaucoma and boost eyesight include: Inositol, Bilberry,
and niacin. More on Glaucoma
Drugs - pharmaceuticals are used to
lower interoccular pressure. Studies have shown that
marijuana, when smoked, lowers intraocular pressure.
Surgery - both laser and conventional
surgeries are used to treat glaucoma. However, these
offer only a temporary solution.
