Vitamin B12 deficiency: Signs may include progressive bilateral but painless vision loss


One case study involving a 63-year-old male presented to the eye clinic for a second opinion following a gradual decline in his vision over the previous two months.

An in-depth chart review revealed that the patient had been diagnosed with vitamin B12 deficiency as a result of routine bloodwork.

At that time, he was prescribed vitamin B12 1000 mcg po daily and folic acid 1 mg po daily.

“The patient’s primary care provider consulted haematology, and treatment was amended to intramuscular cyanocobalamin 1000 mcg/mL once weekly for four weeks and monthly thereafter to be followed by folic acid 1 mg daily po,” noted the study.
