  1. Chemosis
    • edematous swollen tissue
    • from increased vascular permeability
  2. Hyperemia
    • Pale to bright-red engorged vessels
    • Pathophysiologic response to injury
  3. Serous discharge
    • clear and watery
    • increased vascular permeability
  4. Mucoid discharge
    • clear to yellowish tinged, translucent, sticky or stringy discharge
    • increased mucus from goblet-cell irritation
  5. Mucopurulent discharge
    • yellowish white, less translucent, sticky discharge
    • from increased mucus combined with inflammatory cells (e.g. eosinophils and macrophages)
  6. purulent discharge
    • yellowish white to yellow-green tinged, opaque, thick discharge
    • from high concentration of inflammatory cells (i.e. polymorphonuclear leukocytes and macrophages)
  7. fibrinous
    • white,opaque, flat-appearing discharge that follows contour of conjunctiva and may be attached to underlying tissue
    • from high degree of fibrin mixed with inflammatory cells (i.e. polymorphonuclear leukocytes and macrophages)
  8. hemorrhagic
    • red-streaked discharge that may also have any of the foregoing characteristics
    • from RBCs in discharge from increased vascular permeability or trauma
  9. Papillary hypertrophy
    • elevations of conjunctival epithelium and stroma with a delineating margin and small central vascular tuft; when papillae are small, the conjunctiva has a velvety appearance
    • from cellular infiltration of the substantia propria by inflammatory cellular material (i.e. eosinophils, lymphocytes, mast cells, and polymorphonuclear leukocytes
  10. Follicles
    • elevated, avascular, rounded lesions, translucent to whitish gray, usually located in fornices; small vessel may surround the follicle; no central vascular tuft present
    • from germinal cells (immature lymphocytes) and macrophages comprise central portion with mature cells forming the periphery.
