Abstract:
Objective To evaluate the percentage of agreement between the ultrasonographic data and the surgical findings,and investigate the characteristics of the ultrasonographic imaging of proliferative diabetic retinopathy.Methods B-scan ultrasonography was performed in 48 patients (62 eyes ) affected by proliferative diabetic retinopathy,before vitreoretinal surgery,by observing and recording the position,shape,range,to evaluate the percentage of agreement between the ultrasonographic data and surgical findings.Results Ultrasonography can show kinds of vitreoretinal changes clearly,and is not affected by the opacity of refractive media.The agreement was quite good for the pathological changes of proliferative diabetic retinopathy.The accurate rates of diagnosis of vitreous hemorrhage,posterior vitreous detachment,retinal detachment,vitreal membranes,vitreoretinal adhesions and preretinal membranes were 100%, 91.9%, 94.9%, 96.4%, 80.0% and 87.9%,respectively.Conclusions B-scan ultrasonography is valuable in proliferative diabetic retinopathy and favorable in the ophthalmic clinic practice.
