The Ultimate Portrait Painter: Howard Bartner and Forty Years of Medical Illustration
  Drawing 2: Retina Uveitis Hemorrhages  
  Painting of a  retina of a patient with uveitis  
  In 1958, Howard Bartner created his first painting at the National Institutes of Health: this view of the retina of a patient with uveitis, an inflammation of the uvea (iris, ciliary body, and choroid), the middle layer of the eye. As a result, the retinal vessel walls are weakened and are bleeding. The inset depicts a scar in the retina; the retina and choroid have disappeared and the whiteness of the sclera (the outer layer of the eye) can be seen.
