[′pan·əs]

Vascularization accompanied by deposition of connective tissue beneath the cornal epithelium.
Overgrowth of connective tissue on the articular surface of a diarthrodial joint.

Pannus

 

a morbid condition of the limbus and cornea of the eye resulting from a local chronic inflammation. It occurs most often in conjunction with trachoma but may also develop with tubercular-allergic keratoconjunctivitis. The infiltrate formed beneath the epithelium of the cornea is replaced by scar tissue; this causes a significant decrease in vision. Treatment consists of eliminating the primary disease. In the case of trachomatous pannus, surgery is recommended.

On the basis of these findings, it is reasonable to conclude that these miRNAs could potentially promote synovial inflammation, pannus formation, and bone and cartilage erosion during RA pathogenesis via regulation of the Wnt signaling pathway.
Animals treated with dexamethasone, a potent anti-inflammatory corticosteroid, presented with no apparent disease pathology (vi) compared to the vehicle control (vii) which exhibited extensive cartilage destruction, bone erosion, pannus formation, and granulocyte infiltration (Figure 6(d)).
Preparation of the ocular surface: Prior to CLET, the eye with LSCD (Figure 5a) undergoes peritomy (Figure 5b), the fibrovascular pannus tissue is cleared from the ocular surface (Figure 5c), and superficial keratectomy is performed when necessary.
As for other types of arthritis, similar features have also been confirmed, such as vascularization, focal hyperemia, hypertrophic lining, and pannus, which are all found in the samples of PsA.[sup][40] In PsA, researchers observed the proliferation of tortuous vessels from early phases to chronic courses.[sup][40],[41]
In contrast to other acute phase reactants, the majority of PTX-3 synthesis is extrahepatic and in that study the main source of PTX-3 was the synovial pannus. [12]

To assess bladder volume, the abdominal (or cardiac) probe is placed above the symphysis pubis (under the pannus with obesity) and directed caudally towards the prostate or cervix to visualize and measure the maximum transverse and longitudinal bladder diameters (Figure 4).
Deep wedge incisional biopsies taken from the left thigh nodule and calf showed panlobular infarction of subcutaneous fat with extensive mural calcification of small and medium sized vessels within the pannus, with luminal occlusion (Figure 2).
Slit lamp exam showed severe bilateral conjunctival injection, corneal pannus associated with inferonasal peripheral corneal thinning, and stromal scarring.
