The use of Glycerol-Preserved Corneas in the Developing world

The World Health Organization defines blindness as visual acuity worse than 3/60.1 Using this definition, there were an estimated 45 million people bilaterally blind in 2001 and another 180 million people with bilateral severe visual impairment.2 Globally, corneal opacity is the third leading cause of bilateral blindness after cataract and glaucoma, affecting some 7-9 million people, 90% of which live in the developing world.2 Furthermore, corneal blindness is often monocular, generating associated disability, which these statistics do not reflect. Corneal causes of blindness encompass a large number of disease processes, including, but not limited to, infectious inflammatory, traumatic and genetic causes. Of these, trachoma is the most common in the developing world.
