muscae volitantes
An entoptic phenomenon produced by the presence of remnants of embryonic structures floating within the vitreous humour. They appear like floating spots on a bright uniform background. As they are lighter than the vitreous body they tend to float upward but appear to the patient to move downward because of the reversal of the retinal image. Syn. mouches volantes. See floaters; entoptic image; myiodesopia; opacity.
