ABSTRACT
Objective To observe the changes in the circumpapillary thickness parameters measured by optical coherence tomography (OCT) in patients with optic disc edema (ODE).Methods Together 36 patients (36 eyes) diagnosed with ODE from October 2012 to October 2015 were included in the study,and 51 age-and gendermatched control subjects (51 eyes) were recruited from among healthy individuals with no history or evidence of current ocular disease.All the subjects were examined for visual acuity,slit lamp,fundus and fundus photography,and all the eyes underwent OCT scan to detect the circumpapillary retinal nerve fiber layer thickness (cpRNFLT) and circumpapillary total retinal thickness (cpTRT).Results After OCT scan,25 ODE patients (5 mild,14 moderate and 6 severe patients) and 30 patients (5 mild,15 moderate and 10 severe patients) were in line with the requirements of cpRNFLT analysis and cpTRT analysis respectively;there were 50 controls meeting the requirements of this study.There was no significant difference in age and sex between ODE patients and the controls (all P >0.05).The mean cpRNFLT and cpRNFLT in each quadrant of ODE patients were significantly thickened than those of controls,and the superior cpRNFLT was the thickest,followed by the inferior,then the nasal and temporal cpRNFLT,and the difference was statistically significant (P <0.001).The mean cpTRT and cpTRT in each quadrant of ODE patients were significantly thickened than those of controls,and the inferior cpRNFLT was the thickest,followed by the superior,then the nasal and temporal cpRNFLT,and the difference was statistically significant (P <0.001).Conclusion Significantly thickening of cpRNFLT and cpTRT has been observed in patients with ODE as compared with controls,so both circumpapillary thickness parameters measured by OCT can be considered as a new non-invasive quantitative index for the detection and research of ODE.
