AIM: To investigate the differences of the relevant parameters of optic nerve between patients with suspected ocular hypertension and normal people. <p>METHODS: There were 36 eyes of suspected ocular hypertension and 43 normal eyes to test their retinal nerve fiber layer thickness(RNFL), the optic disk parameters, the thickness of macular ganglion cell complex(mGCCT)and visual field index. The analysis and comparison are made on the obtained results.<p>RESULTS: There was significant difference(<i>P</i><0.01)between the patients with suspected ocular hypertension and normal eyes in average, inferior and superior RNFL thickness, optic disk parameters(rim area, cup volume, average C/D ratio)and the average, inferior, superior thickness of macular ganglion cell complex(<i>P</i><0.01). There was statistical difference between two groups in nasal RNFL thickness(<i>P</i><0.05), but there was no statistical difference in temporal RNFL thickness, cup area, mean deviation(MD)and pattern standard deviation(PSD)(<i>P</i>>0.05).<p>CONCLUSION: There is significant difference between normal and suspected ocular hypertension eyes in average, inferior and superior RNFL thickness, optic disk parameters(rim area, cup volume, average C/D ratio)and the average, inferior, superior thickness of mGCCT.
