- Topical Mitomycin-C enhances subbasal nerve regeneration and reduces erosion frequency in the debridement wounded mouse cornea Experimental Eye Research, Exp Eye Res. 2015 Aug 30. pii: S0014-4835(15)30019-1. doi: 10.1016/j.exer.2015.08.023.
One of the most frequently encountered clinical ocular problems is keratoconjunctivitis sicca, or dry eye disease. Over 25% of patients with ophthalmic issues have dry eye disease, and common symptoms include redness, itchiness, and sensitivity to light. Although the cause of dry eye disease has been considered multifactorial, researchers discovered corneal epithelial over-proliferation as one cause of irritation and decreased tear production. GW researchers anticipate that topical mitomycin c, an anti-proliferative medication, can help treat dry eye.
While studying corneal traumas (which send many patients to emergency rooms), GW researchers demonstrated that over-proliferation of epithelial cells is associated with irritation, inflammation, increased cell turnover, and loss of patches of cells on the corneal surface, which can lead to infections. Mitomycin c helped mice heal significantly better from superficial corneal traumas.
Irritation of the eyes makes people miserable
and leads to problems producing enough of the right kind of tears. Existing
topical treatments such as cyclosporine and artificial tears address some
symptoms of dry eye disease. However, there is currently no treatment on the
market for the root cause of dry eye disease. Topical use of mitomycin c may
provide dry eye patients long-term symptomatic relief and prevent complications
like ulcers and infections.
- Effective treatment for dry eye disease
- Treatment of superficial corneal traumas
- Mitomycin c can also treat dry mouth disease (xerostomia) by inhibiting over-proliferation
- Treats a cause of dry eye disease
- Potential for long-term relief for all dry eye symptoms
- Prevents complications from dry eye (ulcers, infections)
