We’ve known for some time that autologous serum – a blood product produced from your own blood by removing the red cells – can bring relief to dry eye sufferers. But this therapy is expensive and tedious and usually reserved for a last resort.
Now, a new study, recently published in Nature, has shown that whole blood – also called Fingertip Autologous Blood, or FAB – can bring about a marked improvement in symptoms. And without the mess or hefty price tag.
HOW DOES THE TREATMENT WORK?
Blood contains nutrients and vitamins that are also present in our tears. In a healthy tear film, micronutrients and vitamins nourish and repair the cells of the eye’s surface. But in moderate to severe dry eye disease, the tears can change their constituents and end up with inflammatory cells taking over. Blood similarly contains these micronutrients and can be used to boost these factors lacking in the tear film of dry-eye patients.
