Glaucoma Screening / Early Detection of Glaucoma
Glaucoma is a disease of the eyes of which approximately 2.4% of the total population aged 40 and older are affected. With higher age, the frequency rises to about 7%. There are already around 800,000 glaucoma patients in Germany and in about 3 million patients a preliminary stage of this disease can be diagnosed.
The disease is characterized by a progressive optic nerve atrophy, associated with a decrease of the field of vision. This degeneration proceeds so insidiously that the glaucoma patients´ damage to their eyes are irreparable. A complete loss of sight is even possible. Due to the insidious nature of glaucoma, it can be difficult for the patients to perceive it.
Our preventive treatment can detect worse eye conditions through glaucoma screening. The optic nerves are analyzed and evaluated in connection with the results of the measurement of intraocular pressure (IOP). In case we find an undiscovered early stage glaucoma, it can be treated with advanced medication.
Only through regular eye exams, the early signs of visual field impairment may be detected.
During its embryonic development, the eye produces water in the posterior chamber. It tends to produce more in morning than at night. The chamber water then flows from the posterior chamber through the pupil into the anterior chamber. Our brain is responsible for providing good flow between production and outflow of chamber water.
If physical pressure that weighs on the inside of the eye increases, a glaucoma can develop.
Pachymetry / Measuring Corneal Thickness
For the measurement of the intraocular pressure, the method of tonometry is generally used. It is based on the required force necessary to reach a defined flattening of the cornea. This measurement method is very reliable for patients with an average thickness cornea.
However, incorrect measurements may result in patients with very thin or very thick cornea.
We can measure the thickness of the cornea with the so-called pachymetry, so that the false values can be corrected by using a correction factor.
Field of Vision Measurement
Since the loss in the field of vision called scotomas may be responsible for glaucoma or other diseases, the field of vision measurement plays a major role in glaucoma screening.
With perimetry, we can determine the field of vision in our practice. The visual field is the area that is perceived by not moving the eye away from a central point. The examination is non-invasive and painless.
OCT – Optical Coherence Tomography
With optical coherence tomography (OCT ), we have the opportunity to gain more differentiated knowledge of diseases of the optic nerve, retina and choroid.
This non-invasive method can often even replace an expensive fluorescent angiographic examination in which a dye has to be injected into an arm vein. The procedure is painless and harmless.
