Glaucoma is an eye affliction
caused by a disturbance of the fluid balance with the eyeball and a consequent
increase of pressure inside the eye. If allowed to persist, glaucoma may damage
vision by pressing against the optic nerve. One of the main symptoms of glaucoma
is a tunnel vision. Well, in other words, an increasingly restricted field of
vision, even though you can still focus perfectly well. Other warning signs and
symptoms which may or may not be present are headaches and seeing auras or
haloes around bright objects. Because glaucoma is an age associated defect it
is rarely seen in people under 35 and because it ca be absolutely symptomless
in the
early stages by the time it is
diagnosed medially, the process has often gone so far that the sufferer can be
classified as blind for health insurance purposes. You should have an eye test
at about the age of 45 to check that you have not got it. This is particularly
important if there is a history of it in your family. Once detected glaucoma
can never be cured but it can be controlled in one of three ways; medically
through prescription of certain drugs, surgically, in order to release pressure
inside the eye, or through the use of prescription eye drops which use a drug
called pilocarpine to constrict the pupil, so making the wearing of glasses
unnecessary.
