Central Corneal Thickness in Northwestern American Indians/Alaskan Natives and Comparison with White and African-American Persons

CCT measurements for the Northwest AI/AN population are similar to those of White persons but thicker than those of African-American persons. Although glaucoma is common in AI/ANs, we did not find an association with thin CCT. We need future studies to explore the risk factors for glaucoma in AI/ANs.
