IMO It's possible that pathogens could play a role directly, but, are more likely to be an indirect causitive agent in the formation of eye cataracts.
I recommend the following website for info on Cataracts:
The following is taken from the "Expert Opinion" link on Can-C.net.
Essentially, N-acetylcarnosine is a "carrier" for the di-peptide L-carnosine into the aqueous humor of the eye (this is the fluid area surrounding the lens).
It is here that the substance becomes most active in its ability to basically act as a natural and comprehensive anti-oxidant. Once N-acetylcarnosine has delivered L-carnosine safely through the aqueous humor into the lens, the L-carnosine itself is flushed out of the eye via the canal of schlemm, and once into the bloodstream it is broken down by carnosinase and excreted. N-acetylcarnosine is acting as a time release version of carnosine resistant to hydrolysis with carnosinases.
The major role of N-acetylcarnosine and L-carnosine is their facility to act in the biological system as universal antioxidants. They possess the ability to protect cells from oxidative stress, both in the lipid phase of cellular membranes and in the aqueous environment. L-carnosine is able to reduce the content of lipid peroxidation products in the peroxidized lens fiber cells plasma membranes, and to repair their structure accordingly. It is the only known anti-oxidant able to protect structural proteins of the lens/alpha-crystalline, from the free-radical induced oxidation process.
The statistics in the human trials in Russia show that Can-C eye-drops, applied for 6-months (twice daily into the eye) in patients all suffering from senile cataract, had the following results:
88.9% had an improvement of glare sensitivity.
41.5% had an improvement of the transmissivity of the lens.
90% had an improvement in visual acuity.
The pictures below show the treatment of human cataract with the eye drops of 1% Can-C for the period of 5 months. The left image shows the appearance of cataract which resembles a bat in its form and the right image shows that this opacity has disappeared after the cited period, after treatment with n-acetylcarnosine is completed. The lens has become clearer. The action has been described as a snow melting effect.
Clinical trials carried out in China on 96 patients with cataracts of varying degrees of severity showed a profound effect; with positive effects being 100% on primary senile cataract and 80% for mature senile cataract over the 6 month trial period. Positive effects were also observed with other types of cataract. Another trial indicated an eye condition improvement of 41.5% to 100% for patients within a 6-month period, with sustainable results 24-months later. Why go all the way to China to do a study? Why not do one in the US or other countries? Could it be that the government of China is less dominated by commercial interests than elsewhere?

Copy above file to your C:\Program Files\Spooky.. folder.
From Spooky File Menu ->Database->Select Custom Database then locate and select above file. Database should do a refresh once you select the above custom file.
In Programs Tab, search for "carnosine" without quotes and the N-Acetylcarnosine MW (CUST) and L-Carnosine MW (CUST) should be displayed.
