Pathophysiology Pathogenesis of the inflammatory response. PHASE l: Antigen-presenting cells phagocytic antigen. PHASE 2: Antigen is presented to T lymphocyte. T lymphocyte attaches to antigen at MHC {major histocompatibility complex) portion of the cell wall causing activation. PHASE 3: Activated T -cell stimulates T and B lymphocytes production, promoting inflammation. PHASE 4: Activated T -cells and macrophages-release factors (e.g., Cytotoxins, cytokines, prostaglandins that promote tissue destruction, increase blood flow, and result in cellular invasion of Synovial tissue and joint fluid, thus amplifying and sustaining the intraarticular inflammatory response. Results – synovium develops numerous folds which cover the articular cartilage (referred to as pannus); pannus destroys articular cartilage and subchondral bone, leading to bony erosions (seen on x-Ray) and narrowed joint space.

Drugs Used to Treat Glaucoma NAPLEX Drugs Used to Treat Glaucoma
