Pannus, Superficial Diffuse Vascular Keratitis (Pannus)

Pannus, Superficial Diffuse Vascular Keratitis (Pannus) is an eye disease characterized by invasion of the outer layers of the cornea by tissue containing a large number of blood vessels that grow into it from the conjunctiva. This leads to disruption of the transparency of the cornea and can lead to decreased vision.

Pannus can develop as a result of inflammation of the cornea or conjunctiva of the eye, especially with trachoma, an infectious disease caused by chlamydial bacteria. However, there may be other causes for the development of pannus, for example, inflammation of the sclera, rheumatoid arthritis or other autoimmune diseases.

Signs of pannus may include varying degrees of cloudiness of the cornea, the appearance of red blood vessels on the surface of the cornea, and a gritty or itchy feeling in the eyes. Longer presence of pannus can lead to ulcers on the cornea, which can lead to corneal perforation and loss of vision.

Diagnosis of pannus includes a visual examination of the eye, as well as special tests to assess the transparency of the cornea. Treatment of pannus may include the use of topical corticosteroids, antibiotics, or immunosuppressive agents. In some cases, surgery may be required, such as keratoplasty - replacing the damaged cornea with donor tissue.

Overall, pannus is a serious condition that can lead to vision loss, so it is important to seek medical help at the first sign of its development. Additionally, preventing inflammatory eye diseases can reduce the risk of developing pannus.

Pannus, superficial diffuse vascular keratitis (also known as pannus keratitis, pannus iris, venture keratitis, or Fox-Punnett disease) is a serious eye disease that is characterized by invasion of the outer layers of the corneal tissue by tissues containing a large number of blood vessels. They grow into the corneal tissue from the conjunctival tissue. Pannus is a fairly common cause of visual impairment, in some cases affecting 25% of the world's population. The average age of those affected is 30 to 40 years, but it can also occur in children. Pannus is often associated with trachoma and can develop in cases where trachoma is not observed. In most cases, pannus manifests itself as an inflammatory process: swelling, lacrimation, itching and redness of the surface of the eye.

Pannus Keratitis is one of the most serious diseases of the eyeball. Pannus implies invasion into the cornea or directly into the surface of the ocular tissue of the vessels located in the conjunctiva and ending up in the keratoconjunctival zone. This pathological formation is manifested by an expansion of the vascular network. It's more common
