Use of Ozone-Based Eye Drops: A Series of Cases in Veterinary and Human Spontaneous Ocular Pathologies

Conjunctivitis, keratoconjunctivitis, and corneal ulcers are common eye disorders frequently diagnosed in both humans and animals, and are currently treated by topical administration of eye drops containing anti-inflammatory and antibacterial agents. The current molecules often lack efficacy because infections in hypoxic tissue contain methicillin-resistant Staphylococcus aureus and Pseudomonas aeruginosa; thus, new products for the treatment of ocular pain and inflammation are needed. The use of ozone, a molecule stabilized for topical use as an ozonide, could be providential due to its anti-inflammatory and bactericidal activity in certain anterior segment pathologies, in addition to promoting tissue repair properties. Ozonated oils have the same properties as gaseous ozone and are well tolerated by tissues. In the present study the repair and regeneration effect of ozonated oil in liposomes plus hypromellose (Ozodrop®, FB Vision, Ascoli Piceno, Italy) instilled 3–4 times a day in external ocular spontaneous pathologies both in animals and humans are reported.
