Factors associated with human vision

The body’s abnormal immune responses can damage brain and nerve cells, resulting in multiple sclerosis, muscle weakness as well as vision problems. In 2007, a study conducted by Johns Hopkins Hospital claimed that an eye test named optical coherence tomography (OCT) could be used to identify and monitor multiple sclerosis. OCT could be used to test health conditions of nerve cells and only cost one-tenth of the fees of performing magnetic resonance imaging (MRI).
