Composite spectral domain optical coherence tomography images of diabetic tractional retinal detachment.

ABSTRACT

This article describes the spectral domain optical coherence tomography (SD-OCT) findings in three patients with diabetic tractional retinal detachment. Three patients underwent fundus photography and SD-OCT imaging before and after pars plana vitrectomy, endola-ser, and membrane peel. On SD-OCT, all three patients exhibited significant improvement or resolution of subretinal fluid after the surgical release of traction. In this case series, a clinically useful method of visualizing SD-OCT images is demonstrated. Composite images were manually constructed with commercially available software by merging high-density B-scans from the macula and optic nerve. The composite image allowed simultaneous visualization of the effects of proliferative diabetic retinopathy on the macula and optic nerve and is particularly helpful in evaluating tractional macular detachment.
