- structured photopsia
- A term used to denote a type of * photopsia (i.e. light flashes) depicting geometric patterns such as circles, squares, hexagonal shapes, etc. The term structured photopsia is used in opposition to *unstructured photopsia and *phosphene. Patho-physiologically, the mediation of structured pho-topsia has historically been associated primarily with aberrant neurophysiological activity in pres-triate cortical neurons.ReferencesAmos, J.F.
