Glaucoma is a "silent killer" like Diabetic Retinopathy. In most cases
it begins un-noticeably and damages the eyes without any sign or
symptom till it is very late. This is the reason that awareness about
glaucoma and its treatment is important to prevent this blinding
disease.
 What is Glaucoma?
Glaucoma is a group of disorders in which [I.O.P] intra-ocular
pressure (I.O.P maintains the shape of the eye ) is raised above the
normal value (11 - 21 mm Hg) in the affected eye , resulting in a
damage to the optic nerve head & irreversible visual field defects.
 What are the risk factors for Glaucoma?
Following are the risk factors for Glaucoma:
 1.Family history of glaucoma especially in parents and siblings (risk
of 10% in siblings).
2.Diabetes mellitus.
3.Thyroid Diseases: Thyroiditis.
4.Refractive error :mostly seen in high Myopes.
5.Cigarette smoking
6.Injudicious use of steroids (eye drops).
7.Age: Mostly glaucoma affect people in the fifth & seventh decade of
their life but it can occur at any age.
 Can glaucoma can occur in children?
 Glaucoma can occur even in young children and infants (Developmental/
Con{*filter*} Glaucoma). Occurring before the age of 3 years it is called
Con{*filter*} Glaucoma.
Between the age of 3 and 30-35 years it is called Juvenile Glaucoma.
 What are the Types of Glaucoma?
There are two main types of glaucoma:
Open Angle Glaucoma & Angle Closure Glaucoma
Normally, the fluid of the eye (aqueous) circulates through anterior
chamber and passes through the angle exits from the eye into the C{*filter*}
of Schlemn but in open angle glaucoma the passage to the c{*filter*}of
Schlemn offer resistance to the flow of aqueous.

In angle closure glaucoma the angle of the chamber is narrow or gets
closed preventing the drainage of aqueous from the eye. Both types
lead to increase in intra-ocular pressure.
 What are the signs & symptoms?
Primary open angle glaucoma usually insidious & asymptomatic (does not
give rise to any symptoms) in early stages.
 In late stages patients may feel pain in eyes (eye-ache).
Some individuals may notice field defects (inability to see certain
areas of the field of vision). Usually this type of glaucoma is
diagnosed on examination by an eye specialist.
Patient with very high I.O.P may complain of occasional colored rings
(haloes) around lights due to transient corneal epithelial oedema.
Patient Can develop delayed dark adaptation.
Reading & close work often present increasing difficulties owing to
accommodative failure due to constant pressure on the ciliary muscle &
it is nerve supply. Therefore patient usually complain of frequent
changes in presbyopic glasses.
How glaucoma can lead to blindness?
Increase in pressure in the eye leads to resistance to flow of {*filter*}
into the eye leading to damage to the optic nerve head which carries
the images to the brain. First it leads to some area of loss of visual
field (the extent of surrounding visible to any one eye). This field
loss progresses gradually till the eye is completely blind.
Early field loss can be detected by an eye specialist with a test
called Visual Field Charting.
 How to diagnose  Glaucoma ?
Glaucoma can be diagnosed by following tests:
Intra-ocular Pressure [I.O.P] or Eye Pressure: Measured by an
instrument called Applanation Tonometer (Normal I.O.P ranges between
11 and 21 mm Hg). It may be mildly raised in open angle glaucoma and
markedly raised in angle closure glaucoma.
In between the attacks of angle closure glaucoma it may be normal. It
may vary at different times of the day and this variation can be
measured by noting pressures round the clock at specified interval
(Phasing / Diurnal Variation).
In low tension or normal tension glaucoma the pressure may never be
higher than normal range.

 Gonioscopy: It's method by which one can assess the angle of anterior
chamber of the eye.
It helps in diagnosing the type of glaucoma or even the vulnerability
of the person to have attacks of angle closure glaucoma.
Fundus examination: The retina and optic nerve of the eye can be seen
by an instrument called ophthalmoscope.
The optic disc undergoes characteristic changes in glaucoma which are
noted by measuring cup : disc ratio or the C : D Ratio [ normal range
is 0.3 to 0.4].
It is increased in open angle glaucoma and later stages of angle
closure glaucoma & is proportionate to the extent of damage done [In
some normal individuals the C : D ratio may be increased].
Visual Fields: It measures the "area of vision"&, the sensitivity of
each point in this area of a single eye.
 In this test patient is shown light targets of various sizes and
brightness and note is made of the area where the patient can see
this. The data thus collected , analyzed & compared with data of
normal population.
 Glaucoma gives rise to characteristic field defects &  progress in a
peculiar manner. This is the definitive test to detect glaucoma and
assess the severity and extent of damage in the eye.
 Can Glaucoma be treated?
Glaucoma can be treated but the damage done by it cannot be reversed.
But further damage to the eye by glaucoma can be stopped.
 The treatment for glaucoma includes:
{*filter*} :Initial therapy of Primary open angle glaucoma is still
medical.
Surgeries: Goniotomy,Trabeculotomy,Trabeculectomy.see Diagram below.
Laser Operation  [ Argon or diode laser trabculopasty ] see laser .
With early treatment, serious loss of vision and blindness can be
prevented.

Judging from numerous advertising posts made by you, I bet that your medical
business is not running well.
