Abstract: Objective To analyze the application value of optical coherence tomography (OCT)in the diagnosis of normal tension glaucoma (NTG).Methods 50 NTG patients (92 eyes)were selected as control group, at the same period 50 cases in our hospital physical examination center for the health examination were selected as the observation group.The optic disc and retinal nerve fiber layer thickness were measured by OCT.The disc diameter, disc area,depending on the cup diameter,optic cup area in the optic disc parameters were observed and compared between the two groups.Results The optic disc diameter between the control group and the observation group had no significant difference (t =1.02,P >0.05),the differences among the remaining nine parameters were significant (t =3.11,2.85,5.63,5.21,4.13,3.06,3.10,6.58,4.36,all P <0.05).Conclusion OCT can measure and analyze the optic disc and retinal nerve fiber layer quantitatively,it is reproducible,clinical early diagnosis of NTG is of great significance,it is worth popularization and application.
