Atrophy Concentric

Concentric atrophy is one of the types of corneal atrophy, in which a decrease in the size of the cornea occurs due to a decrease in its thickness and destruction of corneal tissue along the periphery. The causes of the disease can be various eye injuries, including as a result of industrial accidents, household accidents (for example, when the eye is hit by random objects), as well as infectious pathologies that disrupt the nutrition of the cornea, etc. This leads to a change in shape and loss of transparency of the cornea. In addition, concentric corneal atrophy may be caused by improperly prescribed treatment, the use of medications, or other eye diseases.

Atrophic concentric degeneration (ACD) is a hereditary degenerative lesion of the intervertebral discs, characterized by an uneven decrease in their height (in the form of concentric zones, rings), alternating with thickenings of the fibrous ring around the pathological focus on MRI. ACD usually develops from the sides or from the posterior edge of the disc and is accompanied by the loss of the internal nucleus pulposus or its fragmentation (Florence discs, according to I.M. Ignatov) [2]. Classic intravital ACD can simulate a bone spur[1]. ACD can also occur in patients with existing spondyloarthrosis or late
