Vitreous opacity vs. nervous system - Do eye floaters arise from the visual nervous system?

Floco Tausin author of this article is a graduate of the Faculty of Humanities at the University of Bern, Switzerland. In theory and practice, He is engaged in the research of entoptic (subjective visual) phenomena in connection with altered states of consciousness and the development of consciousness. His interest is to strengthen the public awareness of the spiritual dimensions of entoptics like eye floaters, afterimages, phosphenes, form constants etc., and to reconcile their physiological and spiritual aspects and explanations. His texts, therefore, cover the topics medicine, religion, mysticism, esotericism, spirituality, and philosophy.

For centuries, scholars have found different explanation for eye floaters, the mobile, scattered and transparent spheres and strings in our visual field. Early on, the origin was thought to be in the eye and the phenomenon was considered a disorder or degeneration somewhere between pupil and retina. Today, eye floaters are believed to be an opacity of the vitreous. However, careful observation of floaters reveal regular structures that call the degeneration thesis into question. These structures strikingly resemble the morphological and functional structures of receptive fields of the visual nervous system. Thus the hypothesis of this article: so-called “idiopathic” (harmless) eye floaters are a visible expression of neuronal processes.
