Blindness can result from a variety of causes. At the outset it must be said that any progressive loss of visual function should be followed by an immediate visit to the doctor. This is not a life threatening condition, but blindness is the cause of the dramatic drop in living standards of the patient.
Blindness may end up penetrating injury to the eye, which leads to damage to the cornea, lens and retina particular. In connection with accidents should be mentioned disease which is known assympathetic ophthalmia – called. Sympathetic disease. It is a fact that damage to one eye causes autoimmune granulomatous inflammation of the choroid against proteins. The immune system then attacks another, healthy eye. The only possibility of saving a healthy eye is damaged eyeball enucleation within 14 days after the injury.
In connection with this, it is still growing number of people with diabetes, it is necessary to mention the so-called. Diabetic retinopathy, in which 2% of diabetics causes blindness. That the blind diabetic, has further consequences for him, and that it is statistically proven that it will not live another five years. The blood vessels in the retina are in fact a good indicator of the state of blood vessels throughout the body – in particular in the kidney, brain and heart. Cause of blindness in diabetes is a traction retinal detachment or so. Diabetic maculopathy.
If we are talking about damage to blood vessels in the retina as the cause of the blindness, we must also talk about arterial occlusion of retinal vessels. Occlusion occurs primarily when embolism (source of emboli eg. In the heart valve defects or atrial fibrillation). If the blockage strain central retinal artery occurs practically simultaneously a drastic decrease in visual functions.
Numerous causes of blindness are various types of damage to the optic nerve, visual pathwaysand may also damage the visual centers of the occipital lobe. These are often associated with bleeding injuries, inflammation and the like.
Globally, the most common cause of blindness in developing countries. It is caused by chlamydiainfection of the conjunctiva. A so called. Trachoma – it is estimated that this disease affects approximately 400 milion people worldwide.
