Abstract
Introduction Since the introduction of binocular indirect ophthalmoscopy and scleral depression by Schepens in 1945,1,2this method has been extensively used in the study of normal and pathological conditions of the retina. With experience in this technique, a phenomenon called "white with pressure" has become evident; this manifestation requires scleral indentation for its appearance and has been depicted by Schepens in an earlier publication.3The pathological appearance of retinal attenuation and vitreoretinal adhesions has also been described by Michaelson4and Pau.5However, no report of the pathological correlation of the "white with pressure" phenomenon has been presented to date and such a correlation is the purpose of this paper. The term "white with pressure" or "WWP" signifies an opacification of the retina noticed upon scleral depression. When one indents the sclera of a normal eye and observes the fundus with the indirect ophthalmoscope, a chorioretinal elevationKeywords
