Pigmentary vortex keratopathy in dogs. A whorl patterned distribution of faint white corneal epithelial opacity with pigmentation in both clockwise and counterclockwise directions is present in the central cornea.

Equine corneal stromal abscesses: An evolution in the understanding of pathogenesis and treatment during the past 30 years
Leucocytes are attracted very aggressively in the formation of a stromal abscess suggesting that the immune privilege of the cornea has been disrupted. Vascularisation over the abscess and ventrally is very prominent. Severe uveitis with breakdown of the blood-aqueous barrier and hypopyon can be appreciated in this horse eye.
