title: Ultrasonographic diagnosis of massive periretinal proliferation in eyes with opaque media (triangular retinal detachment).
abstract: A triangular pattern of retinal detachment, as seen by B-scan ultrasonography in eyes with opaque media has been correlated with advanced massive periretinal proliferation (MPP). The ultrasonographic triangular configuration was created by a proliferative membrane that united detached retina anteriorly. Thirteen eyes with opaque media and a triangular retinal detachment by ultrasound had severe MPP at vitrectomy or enucleation. Twelve eyes with clear media with advanced MPP were also studies by B-scan ultrasonography and a triangular detachment could be demonstrated in each case. The finding of a triangular retinal detachment by B-scan ultrasonography in eyes with opaque media is diagnostic of advanced MPP. Eyes with this type of retinal detachment have a poor surgical prognosis even with modern vitrectomy techniques.
