Sudden acquired retinal degeneration (disease)
Sudden acquired retinal degeneration syndrome (SARDS) is a disease in dogs causing sudden blindness. It can occur in any breed, but female dogs may be predisposed. Approximately 4000 cases are seen in the United States annually.
The cause of SARDS is considered to be idiopathic and the veterinary community is divided as to its cause, but the disease possibly involves autoimmune disease, toxins, elevations in adrenal sex hormones or Cushing's disease.
