Researchers, including one of Indian-origin, have identified the presence of a specific type of antibody, called anti-citrullinated protein autoantibodies, or ACPAs, in human tear fluid.
They also demonstrated that patients with dry eye disease experienced reduced signs and symptoms of the condition in response to a new eye drop treatment --- made from pooled human antibodies -- that targets ACPAs, said the study published in the journal The Ocular Surface.
