Three-dimensional optical coherence tomography of proliferative diabetic retinopathy.

Abstract

Fourier-domain optical coherence tomography (OCT) was used to image the three-dimensional (3D) structures of the proliferative membrane in proliferative diabetic retinopathy. The case of a 51-year-old man with retinal detachment of the macula in his left eye is reported. The proliferative membrane covered the entire macular area. In the OCT image, the 3D structure of the proliferative membrane could be clearly visualised. The OCT image showed the presence of multiple adhesions between the retina and the proliferative membrane and separation of the proliferative membrane. The patient underwent three-port vitrectomy, and the extent and locations of the adhesions corresponded well with the findings during vitrectomy. Three-dimensional OCT is an effective tool for understanding the 3D structure of the proliferative membrane in diabetic retinopathy and is useful for training and planning of the surgical procedures in vitrectomy.
