Abstract:
Objective To analyze and discuss the correlations between different areas of corneal thickness and ICare rebound tonometer ( RBT ) .Methods Totals of 108 volunteers were selected as the subjects.Corneal thicknesses (central cornea, 2mm distance of corneal limbus nasal side and temporal side,) were measured by using optical coherence tomography ( OCT) , and intraocular pressure of different corneal areas were measured with RBT.The correlation of corneal thickness and intraocular pressure in different corneal zones were analyzed by Pearson correlation analysis.Results Thicknesses in central cornea,2 mm distance of corneal limbus nasal side and temporal side were (527.84 ±32.93), (551.31 ±35.40) and (533.91 ±34.42)μm, respectively.Numbers of IOP were (16.39 ±5.31), (16.37 ±5.48) and (16.44 ±5.72) mmHg, respectively.Central corneal (r=0.319,P<0.01), nasal side (r=0.267,P<0.05),temporal side (r=0.299, P <0.02 ), positive correlation was found between corneal thickness and intraocular pressure. Conclusions Corneal thickness of different areas will affect measurement results of intraocular pressures by using ICare rebound tonometer.
