Once daily instillation of T1225 1.0% and 1.5% was shown to reach an AUIC markedly above the required threshold for an antibacterial activity against Gram-positive bacteria (25-35). These results suggest that a BID instillation is more likely to ensure antimicrobial activity against Gram-negative bacteria (threshold >100).

After 12 weeks of supplementation with Oxybiane, both the BUT scores (27.3%+/-8.4% with Oxybiane versus 3.61%+/-4.3% with the placebo, p=0.017) and the Schirmer scores (26.9%+/-14.2% with Oxybiane versus -4.7%+/-3.4% with the placebo, p=0.037) were significantly increased. A significantly improvement was also observed considering subjective clinical symptoms such as burning (p=0.031), itching (p=0.027), sensation of foreign body in eye (p=0.030), and redness (p=0.043). CONCLUSIONS. Supplementation with oral antioxidants can improve both tear stability and quantity but also subjective clinical signs.

Transcription factor KLF6 downregulates the alpha1-PI gene in corneal epithelial cells and may thereby be involved in keratoconus.
