The eye disease glaucoma (glaucoma) is treacherous: The threat of damage to the optic nerve and optic nerve is in the early stages of the affected hardly recognizable. They are often alarmed only when vision is impaired, or when the so-called glaucoma pressure increases the pressure in the eye threatening. Some of the signs are nonspecific. That is, they could also be caused by other diseases and do not yet allow the diagnosis of cataract. Symptoms of glaucoma can affect vision, the eyeball, as well as the general condition. Find out everything important to the most common symptoms of the Green Star here.
Green Star: “Visual disturbances and visual field defects in the Green Star”
Significant damage to the retina and / or optic nerve has already occurred when sufferers notice their eyesight limitations and the ophthalmologist diagnoses them as the cause of cataracts. Because only when larger areas of the retina are damaged or there about one third of the nerve fibers are no longer intact, these typical glaucoma symptoms occur. Doctors call the failures “scotomas”.
The examining doctor determines scotomas by means of so-called perimetry. For this he presents the patient with objects in different areas of the field of view, without the latter being allowed to change his line of vision. In doing so, he documents the patient’s feedback for each position; the overall picture then reveals any existing visual field defects.
Due to the course of nerves and blood vessels narrows the field of vision of the eye in people with glaucoma arched from the outside. Typically, these go from the blind spot in the glaucoma patient (Bjerrum scotoma). Occur occasionally too Visual field defects in the center of the visual field on.
Other deterioration of vision may occur in certain forms of glaucoma if deposits form on the lens of the eye and in the angle of the chamber during the course of the disease. In so-called pseudoexfoliation glaucoma (PEX glaucoma) these deposits tarnish the lens, sometimes affecting those affected Loss of visual acuity and contrasts to notice.
With prolonged high intraocular pressure, edema of certain cells in the eye can lead to refraction of light, which manifests itself as colored rings or courtyards (Auras) seem to form bright light sources. Does not occur at the same time already vision loss the sufferers often perceive light as very bright and unpleasant (photophobia).
At the Glaucoma attack – A dramatic, sudden increase in pressure in the diseased eye – may occur in addition to other symptoms, a sudden loss of vision, because the visual cells and the optic nerve with its high oxygen and nutrient requirements suddenly the blood supply is literally clamped. A glaucoma case is a medical emergency in which the intraocular pressure has to be normalized so quickly. Only if this succeeds quickly, the affected cells can recover and the vision returns.
Green Star: changes in the eye at the Green Star
Glaucoma symptoms in the outer eye and its surroundings occur especially in acute glaucoma (glaucoma case): The Eye is red and swollen, of the Eyeball feels very hard, often flow simultaneously tears, Glaucoma symptoms in acute seizure are also one extended pupil and a missing light reactionthat is, when the light falls, the pupil no longer or hardly narrows.
Green Star: General symptoms of the Green Star
If a cataract is associated with increased intraocular pressure, general symptoms of illness may also occur. Especially in the case of glaucoma – ie a sudden increase in pressure to very high levels – these are often very severe headache, nausea and vomiting, sometimes too Cardiac arrhythmias and collapse. A glaucoma case has to treated immediately and the pressure in the eyeball will be lowered.
Green Star: Symptoms in infants and toddlers
In infants and toddlers up to two years, a green starling (primary congenital glaucoma) is particularly treacherous, because the typical Glaucoma symptoms babies can not communicate. Parents should therefore be alerted and consult the ophthalmologist if their child is restless and the Hands repeatedly leads to the eyes, this rubs while whining or screaming. Children with congenital glaucoma often have unusually “beautiful, big eyes” – a direct result of the high pressure inside the growing eyeball. Often, the little ones also stubbornly avoid looking into the light (photophobia), your Eyes tears and you close the eyelids convulsively.
