Sudden onset of blindness in cats
Sudden onset of blindness in cats is most often the result of systemic hypertension (high blood pressure).
Various infectious diseases (viral, fungal, bacterial) and cancer can also cause sudden loss of sight. Unfortunately, blindness in cats can also be caused by long-term use of some systemic antibiotics (fluoroquinolones).
Many causes of sudden onset of blindness in cats cause reversible loss of sight, so if the diagnosis is made in time and appropriate therapy is started, the eyesight can be preserved.
