title: [Idiopathic preretinal macular fibrosis. Study of correlation between morphologic changes and visual acuity].
abstract: Idiopathic preretinal macular fibrosis is an affection characterized by the development of preretinal membranes, macular distortion and, sometimes, macular edema. These changes as well as the consequent reduction of the visual acuity may vary very widely from one case to another. In this study, the degree of correlation among the various retinal morphological changes and among them and the visual acuity was investigated. This study shows that the importance of retinal distortion is strictly dependent on the appearance of the preretinal membranes that the appearance of the preretinal membrane and the importance of the retinal distortion are equally valid predictors of visual acuity, that the macular edema (defined as fluorescein leakage) depends mainly on the degree of contraction of the preretinal membrane and that such leakage does not represent the best parameter in order to predict the visual acuity.
