Blue-field entoptic phenomenon 2026-02-26T09:31:28Z Blue field phenomenon is thought to result from the autovisualization of the own leukocytes in the retinal capillaries. Unremitting, positive visual phenomena, present in the entire visual field and characterized by uncountable tiny flickering dots interposed between the person's vision and the background. The dots are said to resemble static and are typically black and white but can also be colored, flashing, or transparent. In addition to the static, or snow, patients can experience additional visual symptoms of either direct neurological origin, such as palinopsia, photophobia, and nyctalopia (i.e., impaired night vision), or that arise from the optic apparatus.
