This image depicted what is known as a fundoscopic view of the retina, or the back of the left eye. Note the optic cup located left of center, at which point, the optic nerve and artery entered the back of the eye. This was a case of synchysis scintillans, which involves the liquefaction of the vitreous humor, normally a jelly-like, clear, colorless substance that fills the eye chamber, just posterior to the lens. The minute, spotty bright debris, is composed of cholesterol crystals within the vitreous humor. Synchysis scintillans is associated with cases of advanced diabetic retinopathy, and is only rarely encountered, both in humans, and canines.
