Glaucoma
Glaucoma is the leading cause of blindness in
the Western World. In Egypt, it is one of the major causes. It is a disease that
typically affects older people, but it can occur at any age. Loss of vision is
preventable if the disease is detected early and treatment is started.
The eye has about 1 million tiny nerve fibers which run from the back of the eye
to the brain. These nerve fibers allow us to see. Glaucoma is a disease which
causes the destruction of these fibers. It was once thought that the loss of
these fibers was due strictly to high pressure in the eye. But now it is known
that even patients with normal eye pressure can have glaucoma and loss of these
nerve fibers.
The average pressure for most people is 10-21. In classic
glaucoma the optic nerve becomes damaged when the pressure gets above 21. This
is called Primary Open Angle Glaucoma. However, Many people with a
susceptibility to glaucoma do have optic nerve damage with much lower pressures.
This is called Normal Tension Glaucoma

Saving Your Sight With A Simple Test "For most people with glaucoma, there are absolutely no warning signs, The only way to detect glaucoma and preserve your sight is to be
tested by an eye specialist or ophthalmologist. During ‘applanation’, the
preferred method of testing eye pressure, the eye is anesthetized with eye drops
and the patient is asked to look at a blue light. Then, using a special
instrument, the doctor briefly touches the surface of the eye to measure the
pressure. The doctor will also look inside the eye to examine the nerve that
connects the eye to the brain. The test itself is simple and painless. If there
are any abnormalities, additional testing may be needed.
- Early detection and regular follow up
- Early
detection of glaucoma is the key factor in preserving good eye sight in most
patients. Dr Khalil has detected many cases, which were otherwise passed
undiagnosed, of early glaucoma. We
have access to the latest and most advanced means of glaucoma detection
including the newest visual field examination machines and
nerve fiber layer analysis. This will sometimes allow detection of glaucoma
long before other tests show any signs of disease. Routine eye examinations
are recommended
-
- Dr Khalil is following the newest surgical techniques
done in various glaucoma centers around the world.
-
- Glaucoma in infants
- Dr Khalil is among very few in the country who are
specifically managing the difficult infantile glaucoma, with special
techniques and instruments.
-
- Laser Treatment for glaucoma
- It is possible to treat and manage some forms of
glaucoma, without resorting to direct surgical intervention, but with using
laer (surgery).
