Abstract: Objective Objective To investigate the relationship between choroidopathy and integrated backscatter(IBS) of choroid in diabetes mellitus(DM) patients.Methods Eighty DM patients of 158 eyes were divided into 3 groups by the course of diabetic retinopathy(DR)-DM patients without DR group,DM patients with the background DR,DM patients with the proliferative DR.80 normal persons of 160 eyes were the control group.Their IBS values were measured on nose side,temple side and middle side of choroid by HP Sonos 5500,and the correction IBS values(IBS％) were calculated.Results With the deterioration of DR,the IBS and IBS％ of choroid increased.The statistical significance difference were found in various groups(P ＜ 0.01).Conclusions With the deterioration of diabetic choroidopathy,the IBS and IBS％ increased.The IBS technique is useful method to assess the diabetic choroidopathy.
