Living with glaucoma
A diagnosis of glaucoma shouldn't prevent you from enjoying your life
or living life to the fullest. When you have the facts, you can take
charge of your health with just a few adjustments to your routine.
Remember, most cases of glaucoma can be managed with medication
alone, and surgery becomes essential only, when medication fails to
control the disease. With early diagnosis the risk of going blind from
glaucoma is minimal. Glaucoma comprises a group of ocular disorders of
the eye characterized by pressure related damage to the optic nerve.
Although glaucoma damage is associated with multiple risk factors, its
major determinant is an intra ocular pressure that is too high for the
normal functioning of the optic nerve.
Uncontrolled glaucoma results in a progressive and irreversible
contraction of the visual field that may ultimately lead to blindness.
Although several theories exist for the mechanism of optic nerve damage,
lowering the intra ocular pressure is currently the only proven
treatment available to halt the progression of the disease.
Risk factors
Glaucoma is the leading cause of irreversible blindness in both the
developing and the developed world. It can occur at any age. However it
is more prevalent in older adults affecting approximately 2-3% of the
population over the age of 40 years.
Although intra ocular pressure is the major risk factor as well as
the treatment focus for glaucoma, other risk factors include genetic
predisposition, increasing age, diabetic mellitus, hypertension, myopia
migraine and other vasospastic disorders.
Some people are predisposed to optic nerve damage even if the intra
ocular pressure is "normal" (i.e. Normal Tension Glaucoma) especially in
the presence of other risk factors. In others, glaucoma damage may also
progress despite the elevated intra ocular pressure been normalized.
However in the vast majority glaucoma can be controlled with effective
treatment.
Daily life with glaucoma
Your medication schedule will probably be the biggest change to your
daily life. Schedule instilling drops to your eyes and visits to your
doctor around your other daily activities. Soon they will become a
normal part of your daily life.
