They destroy the optic nerve. Glaucoma is a drainage disorder of the aqueous humor with a morbid increase in intraocular pressure. The causes as well as the individual complaints may be different, but common to all forms is that the optic nerve is permanently damaged by the excessive pressure in the eyeball. This can lead to blindness.
In most cases, the increase in intraocular pressure plays a major role as the cause of the disease. Outflow disturbances of the aqueous humor in the so-called chamber angles lead to an imbalance between the continuous production in the ciliary body and the outflow. The fluid builds up in the eye, the pressure increases. This increased intraocular pressure primarily damages the sensitive optic nerves. Damaged nerve tissue, however, can no longer pass on all the information to the brain and it comes to the glaucoma typical visual field defects.
Overall, glaucoma can be classified into four major groups. These include primary open-angle glaucoma, which is caused by a drainage obstruction of the aqueous humor directly in the drainage area. The primary angle or narrow angle glaucoma arises due to a congenital narrowing of the angle of the chamber. Primary congenital glaucoma occurs in newborns and infants, and secondary (acquired) glaucoma arises as a result or complication of other ocular diseases, during which the outflow of aqueous humor is obstructed.
The most common is open-angle glaucoma – the majority of glaucoma patients suffer from this disease. Much rarer is u.a. Angular block glaucoma, in which the intraocular pressure can increase massively. In addition to redness, this event causes severe pain – and this is atypical for glaucoma, which is otherwise very slow and hardly causes any discomfort. However, with high intraocular pressure, so-called epithelial edema can cause colored rings or courtyards around light sources.
Furthermore, there are congenital glaucomas and so-called secondary glaucoma. Primary congenital glaucoma is characterized by fainting, watery eyes and eyelid cramps in the affected children. For very big eyes of …
