Recognizing Pathology

White without Pressure

White without pressure is a retinal phenomenon produced by vitreous traction on the surface of the retina. Because it is a superficial phenomenon, it will be more apparent on the green separation. It appears as a whitish degeneration (film) on the retina and typically there is a dark zone along the posterior border (often appears red on binocular indirect ophthalmoscopy which may give the appearance of a pseudo-retinal tear). It may have a rather scalloped posterior margin.
