Abstract:
Objective To observe the changes of subfoveal choroidal thickness (SFCT) in diabetic patients with non-proliferative diabetic retinopathy (NPDR) and clinically significant macular edema(CSME),and then investigate diabetic SFCT and the relationship of diabetic CT with diabetic retinopathy (DR).Methods The patients were divided into 2 groups according to clinical guidelines of DR in China in 2014,including NPDR CSME + group(21 eyes) and NPDR CSME-group(36 eyes).All patients were underwent best corrected visual acuity (BCVA),intraocular pressure,axial length,slit lamp microscope,indirect ophthalmoscope,EDI-OCT examination,and mean arterial blood pressure measurement.The differences of BCVA,central retinal thickness (CRT) and SFCT between NPDR CSME + group and NPDR CSME-group were studied as well by means of using SPSS 18.0 for data statistics.Results There was no significant difference in gender,age,eye axis and intraocular pressure between NPDR CSME + group and NPDR CSME-group (all P ＞ 0.05).There was significant difference in BCVA between the two groups (P =0.001).The mean SFCT were (328.24 ± 101.92) μm in the NPDR CSME + group and (235.31 ± 66.98) μm in the NPDR CSME-group,and the difference was statistically significant (t =4.156,P=0.000).And plotting changes in CRT against changes in SFCT in patients with CSME revealed a positive correlation(r =0.473,P =0.000).Conclusion SFCT in NPDR CSME + patient is thicker than that in NPDR CSME-patient.And plotting changes in CRT against changes in SFCT in patients with CSME reveals a positive correlation.
