What are the rods and cones, many will remember from the course curriculum. These cells — photoreceptors — perceive the light wave and transmitting the image to the brain. Sticks responsible for twilight vision, and cones that allow to distinguish between colors, are located in the retina — the light-sensitive inner layer of the eye.
Diseases of the retina (retinopathy) can occur at any age — as neonates and the aged. Most often disease of the retina associated with the violation of its blood supply. Vascular lesions of the retina is often accompanied by hypertension, diabetes, kidney disease. Problems with the retina may be laid down genetically (the group of so-called hereditary retinal dystrophies), Andarise as they age (senile macular degeneration). Furthermore, in the retina, as well as other eye membranes can arise inflammation (retinitis). Babies born prematurely, vision problems may be associated with hypoplasia of the retinal vessels and the formation of the so-called retinopathy of prematurity.
The most serious consequence of diseases and injuries of the retina is itsdetachment, which may lead to absolute blindness.
If you experience problems with your vision as early as possible is important to see an ophthalmologist and begin treatment. The later the treatment is initiated, the greater the chance of developing serious complications that can lead to a reduction or even a complete loss of vision.
