Many people are often confused about the symptoms that present with visual snow. Of course, the hallmark symptom is visual snow itself. However, in addition to this, sufferers of visual snow also often have a cluster of other physical signs and symptoms.
Visual Snow Symptoms
- Visual snow – Seeing snow or television-like static in parts of or the whole of your visual field. Visual snow can be any color but it usually consists of small, translucent dots whose flicker intensity varies from person to person.
- Palinopsia – A visual disturbance that causes images to persist to some extent even after their corresponding stimulus has left.
- Tinnitus – Characterized by a noise or ringing in the ears.
- Floaters – Spots or specks that wander indiscriminately around in your visual field.
- Light sensitivity - Also known as photosensitivity, light sensitivity is identified by an increased sensitivity to light. This includes artificial light as well as natural sunlight.
- Phosphenes – A phenomenon characterized by seeing light without light actually entering the eye.
- Blue field entoptic phenomenon – Commonly known as Scheerer’s phenomenon, it is the appearance of tiny bright dots which move quickly along squiggly lines in the visual field, when looking into bright blue light (most often the sky).
- Halos/rays – Also commonly referred to as starbursting, consists of seeing halos or rays around sources of light. This also includes reflected sunlight off a car, for instance.
- Benign fasciculation syndrome – Characterized by twitching of various voluntary muscles in the body.
- Haidinger’s brush – An entoptic phenomenon in which people are able to perceive polarization of light.
- Purkinje’s tree – A visual phenomenon characterized by seeing the retinal blood vessels in one’s own eye.
- Eustachian tube problems – In addition to tinnitus, sufferers of visual snow often experience ear fullness as well as a clicking sound when swallowing.
