PANNUS Meaning and
Definition
-
Pannus, a noun, refers to an abnormal overgrowth of fibrovascular tissue on a bodily organ or surface. This term is commonly used in medical contexts, particularly within the field of dermatology and ophthalmology. Pannus can develop as a result of chronic inflammation, autoimmune disorders, infections, or certain other underlying medical conditions.
In dermatology, pannus often describes an excessive formation of granulation tissue in the skin, typically in response to constant irritation or injury. This condition is commonly observed in chronic wounds, such as venous ulcers or pressure sores, where the body's natural healing process becomes dysregulated.
Furthermore, pannus is frequently used in ophthalmology to describe an abnormal growth of blood vessels and connective tissue on the cornea, the transparent front part of the eye. Corneal pannus often arises due to chronic inflammation caused by conditions such as ocular surface disorders, autoimmune diseases like rheumatoid arthritis, or infections like trachoma.
Treatment for pannus depends on the underlying cause and severity of the condition. In some cases, it may involve addressing the primary disease or infection, while others may require surgical intervention to remove or reduce the tissue overgrowth. Regular monitoring and management of pannus are essential to prevent complications and preserve the affected organ's function.

It occurs in three forms: p. crassus, in which the blood-vessels are many and the opacity very dense; p. siccus, associated with xerophthalmia; p. tenuis, in which the blood-vessels are few and the opacity slight.
