Fundus
entire neurosensory retina receives a direct blood supply.
Holangiotic vascular pattern
Neurosensory retinal blood vessels are localized to a horizontal streak on either side of the optic nerve. Seen in lagomorphs
Merangiotic vascular pattern
neruosensory retinal blood vessels are only near the optic nerve seen in equids
Paurangiotic vascular pattern
Neurosensory retina in absent of any blood vessels
Anagiiotic vascular pattern
separation of the neurosensory retina from the retinal pigment epithelium.
