[Entoptic phenomena and potential visual acuity].
REVIEW OF PREOPERATIVE EVALUATION OF VISUAL FUNCTION: In the presence of media opacities, the prevision of the potential postoperative visual acuity constitutes often a complicate diagnostic problem. Its solution requires the experience of the ophthalmologist, who should take into account various elements from the patient's visual aggravation progress, the dissociation between far and near vision under mesopic and scotopic conditions, the actual grating acuity and the eventual hand movement and light-perception, as well as, elements from the patient's objective examination, i.e., from the biomicroscopy with direct and indirect illumination through the still transparent media and from the binocular ophthalmoscopy of the fundus. METHODS REVIEWED: Purkinje figure and luminous darting points visualization. POSSIBLE PREDICTIONS: Light induced entoptic imagery, as Purkinje figure and luminous darting points, visualization, helps as a supplementary diagnostic procedure, for the prevision of a low, but socially useful postoperative visual acuity.
