Glaucoma refers to various pathological changes of the eye. "Glaukos" comes from the Greek and means green. The glaucomatous eye shows on closer inspection a greenish glow. Most people, this disease is probably known as a green star. In addition to this, there is still the cataract, which is called cataract in medical jargon.
See, hear, taste ....
Our sense organs enable us to contact our environment. The eye is the most important of all and at the same time the most technically demanding in terms of design and function.
Two factors are mainly responsible for the development of glaucoma:
- A disturbed blood supply to the optic nerve
- An elevated intraocular pressure
Green star causes damage to the nerve fibers in the retina area. Visual field defects are the consequences. In almost all cases the intraocular pressure is increased (> 21 mm Hg). However, this does not have to be accompanied by glaucoma, but it can be regarded as a precursor. In Germany, about three million people suffer from high intraocular pressure.
More common than commonly suspected
The green star is not a rare phenomenon. In Germany, approximately 800, 000 people have glaucoma. With increasing age the frequency increases. Approximately 2% of over-40s are estimated to be affected. Beyond the age of 75, it is already between 7% and 8%. Age is the number one risk factor. In Germany, glaucoma is one of the most common causes of blindness.
Preventive examinations are recommended from the age of 40. Together with the ophthalmologist, this serious disease is treatable.
Green Star - cataract
These two diseases have nothing in common except their similar name, but are often confused.
The cataract usually occurs only in old age. There is a clouding of the eye lens and vision diminishes. With drugs, the cataract is untreatable. In order to improve vision, the patient must undergo surgery, which today is outpatient.
