AIM: To observe the differences in central cornea thickness, anterior chamber depth, corneal anterior curvature and corneal posterior curvature between the Uygur and the Han nationality college emmetropia students, and analyze the relationship of corneal thickness and corneal curvature.

METHODS: More than 500 students in grade one in Xinjiang Medical University were underwent screening, 56 emmetropia eyes in Han nationality students and 51 in Uygur students were selected. Sirius corneal topography was applied to the measurement.

RESULTS:Uygur and the Han nationality college emmetropia students central cornea thickness(Uygur: 0.53±0.03mm, Han: 0.54±0.03mm), anterior chamber depth(Uygur: 2.91±0.26mm, Han: 3.14±0.25mm), corneal posterior curvature K2(Uygur: -6.30±0.23D, Han: -6.38±0.28D)had significant difference(P<0.05). Corneal anterior curvature(K1, K2)before and corneal posterior curvature K1 there was no significant difference(P>0.05). Han had no significant relationship in corneal thickness and corneal anterior curvature(r<0), or in corneal posterior curvature(r<1). Uygur has no significant relationship in corneal thickness and corneal anterior curvature(r<0), or in corneal posterior curvature(r<1).

CONCLUSION: There are significant differences between the Uygur and the Han nationality college emmetropia students in cornea thickness, anterior chamber depth and corneal posterior curvature K2. There is no significant relationship between corneal thickness and corneal curvature in Uygur and the Han nationality college students.
