This symptom was first described by the Russian neurologist D.L. Voronov and is a ring-shaped area of ​​reduced sensitivity on the skin that surrounds a protruding swollen area. This area is usually found on the extremities, but can appear on other parts of the body.

Voronov's pseudoatrophic rim can be a sign of diseases such as multiple sclerosis, Lyme disease, herpes zoster, diabetic neuropathy and others.

In conclusion, Crow's pseudoatrophic band is one of many symptoms that can occur with various diseases of the nervous system. If you suspect this symptom, you should consult a doctor for diagnosis and appropriate treatment.

Voronov's pseudoatrophic rim (d.l. Voronov; synonym Voronov's symptom) is a clinical symptom characterized by the appearance of a pseudoatrophic rim around the optic nerve head.

This symptom was first described by the Russian ophthalmologist V.N. Voronov in 1903 while studying patients with progressive muscular dystrophy. With this disease, muscle degeneration occurs and lipids accumulate in them, which leads to muscle weakness and atrophy.

Ophthalmoscopy in such patients reveals the appearance of a whitish pseudoatrophic rim around the optic nerve head. This rim occurs due to lipid deposition in the peripapillary retinal nerve fibers.

Thus, Voronov's pseudoatrophic rim is one of the classic signs of progressive muscular dystrophy and other hereditary myopathies. Its appearance indicates the active course of the disease.
