It has been demonstrated in peer-reviewed published studies that bovine lactoferrin, an antimicrobial glycoprotein included in the BioTears formulation, can inhibit adenovirus (a group of viruses that cause respiratory tract and eye infections). Lactoferrin has also been shown to exert its antiviral activity during the earliest phases of infection in a number of other viruses investigated to date. This is particularly important information given the current threat of viral diseases for which we have no vaccine.

As the population lives longer, reducing the level of disability caused by age-related diseases is becoming more important. Activities central to independent living, which include reading, driving, and writing, are considerably impaired through the loss of central vision due to AMD.

For the non-scientists, meta-analyses combine similar small studies together in an attempt to better assess the effects of a treatment. Meta-analyses are often considered the final word on the effects of those treatments, although there are serious limitations to this approach.

A paradoxical effect of certain genes associated with type 2 diabetes, Alzheimer's and macular degeneration is linked in various studies to elevated homocysteine level, which is linked back to vitamin B6, B12 and folate deficiency. The oral insulin medications prescribed today for most type 2 diabetics is metformin and glyburide: both further inhibit normal absorption of vitamin B12 and folate.
