Bleeding into the eyes and
retinal changes such as swelling and detachment can occur, and this may result in damage to the cat's vision (and even blindness), which is often permanent.
Research from the University of Eastern Finland (UEF) shows that
retinal changes may be detected earlier than brain changes.
Treatment - related findings included abnormal feces, effects on coagulation,
retinal changes, neurological abnormalities, ECG changes, gross pathology changes and organ weight changes.
Retinal changes can be complicated to interpret.
