Does a drop of blood a day keep the dry eye away?

Researchers at Moorfields Eye Hospital in London are testing a therapy for treating dry eye and it involves using the patient’s own blood.

The unique technique puts a finger-prick amount of the patient’s blood into the lower eye lid.

The results were surprising. Patients saw symptoms including stinging and redness reduced within three days of starting the therapy and after only eight weeks, the severity of the symptoms was reduced by a third.

Human blood contains the same natural lubricating nutrients that are found in tears. One of these components is the epidermal growth factor, which cannot be found in artificial tears. The 16 dry-eye patients placed a drop of their own blood four times a day into their lower lid. The only side effects experienced were temporary blurred and red vision upon application.*
