Flashes and Floaters
A “floater” in one’s vision may be innocuous or may be serious, depending on the type. The great majority of “spots” in ones vision are annoying but harmless tiny opacities in the vitreous humor of the eye. However, when a new floater develops, patients should be evaluated by an ophthalmologist to determine the underlying cause.
A posterior vitreous separation is the most common cause of new floaters in the aging eye and may occasionally be associated with retinal hole development, which requires immediate attention. Other common causes of floaters in the eye include uveitis and vitreous hemorrhage. Retinal detachment may produce a “shower” of floaters due to a torn retinal vessel and is sometimes preceded by a single large floater. Blind spots in the vision may be due to stroke or other neurological disorder.
