The Role of Central Corneal Thickness in Ocular Hypertension and Primary Open Angle Glaucoma

Glaucoma denotes a broad and heterogeneous range of ocular diseases, all of them sharing a damage to the optic nerve which, on the long run, is able to cause irreversible visual field loss and vision impairment. According to a popular and authoritative study conducted in 2006 by Quigley and Braman [1], glaucoma is the second leading cause of blindness worldwide: the aforementioned study reports that the estimated number of persons affected by glaucoma is around 60 million in 2010 and such a number is expected to increase to 79.6 million by 2020.
