Multiple evanescent white dot syndrome occurs mostly in females. Symptoms include a sudden loss of central vision, but patients eventually regain normal vision. The white dots are small and located in the posterior pole at the level of the retinal pigment epithelium. The white dots may disappear after the first few weeks of the disease.
Many variations occur, but scintillating scotoma usually begins as a spot of flickering light near or in the center of the visual field, which prevents vision within the scotoma area. It typically affects both eyes, as it is not a problem specific to one eye. [5] [6] The affected area flickers but is not dark. It then gradually expands outward ...

If your whole eye has gone red, learn about the causes of bloodshot eyes and how to fix them. Weirdly enough, a red spot on eye might have a cause totally unrelated to your eyes: sneezing or coughing.

[citation needed] In summary: Visual snow as a temporary occurrence under certain conditions is normal and doesn't require ...
