Webal.30 recently reported that CCT was linked to disc size, thicker corneas being associated with smaller optic discs. Finally, Toh and associates31 in Australia recently showed that CCT is among the most highly heritable aspects of ocular structure. The preponderance of these findings hints at a link between both the thickness and material Those patients with thicker CCT may show a higher reading of IOP than actually exists. This means their eye pressure is lower than thought, a lower IOP means that risk for developing glaucoma is lowered. However, it is still important to have regular eye exams to monitor eye pressure and stay aware of changes. See more Corneal thickness is important because it can mask an accurate reading of eye pressure, causing doctors to treat you for a condition that may … See more Many times, patients with thin corneas (less than 555 µm) show artificially low IOP readings. This is dangerous because if your actual IOP is higher than your reading shows, you may be at risk for developing glaucoma … See more People at high risk for glaucoma includes people with increased eye pressure; everyone over the age of 60; people of African descent over the age of 40; and people who have a family history of glaucoma.
