Other types of glaucoma
1: Normal-Tension glaucoma
2: Secondary glaucoma
3: Narrow-angled eye
1: Normal-Tension glaucoma
The patients of this disease have visual field loss although
their intraocular pressure is normal. For the normal-tension glaucoma
patient, normal pressure is too high for their optic nerve. Therefore,
the major aim of the therapy is to reduce the pressure low enough
for the patient. Recently, an ocular blood circulation defect
has often been discussed in glaucoma research groups and they
point out that the improvement of the ocular blood circulation
by medication prevents visual field loss.
2: Secondary glaucoma
This type of the glaucoma often develops after eye injury or ocular
inflammation and in most cases the outflow facility of the aqueous
humor of the eye is damaged. The therapeutic goal of curing the
glaucoma is mostly the same as the chronic glaucoma.
3: Narrow-angled eye
The narrow-angled eye is usually small and hyperopic and this
type of eye often suffers from the acute angle-closure glaucoma.
Laser therapy is recommended to prevent damage when the grade
of the narrowing is quite harmful to the patient. This type of
angle is often can be seen in the Asians, Afro-Americans and Eskimos.
In the Caucassians, narrow-angled eye is relatively rare compared
with the above races.
