Floaters and Flashes

Floaters are small specks or spots that seem to “float” across the visual field and are often described as looking like cobwebs, dots, or lines. Flashes of light, on the other hand, are brief but bright flashes or streaks of light that may appear in the visual field. Both floaters and flashes can be caused by a variety of factors and may indicate an underlying eye condition.

Causes of floaters and flashes

Floaters and flashes are most commonly caused by changes in the vitreous, which is the gel-like substance that fills the eye. As we age, the vitreous may shrink or become more liquid, causing it to pull away from the retina. This can cause floaters to appear in the visual field.

Flashes of light, on the other hand, may be caused by the vitreous pulling on the retina. This pulling can stimulate the retina and cause it to produce the sensation of flashes of light.

In addition to age-related changes in the vitreous, floaters and flashes may also be caused by other underlying conditions such as retinal tears or detachments, inflammation, or infections.

Treatment for floaters and flashes

In many cases, floaters and flashes do not require treatment and may gradually improve over time. However, it is important to schedule a comprehensive eye exam with an ophthalmologist to rule out any underlying conditions that may be causing the symptoms.

If a retinal tear or detachment is detected, treatment may involve a procedure known as a laser photocoagulation, which uses a laser to create small burns around the tear and seal it shut. If a retinal detachment occurs, surgery may be necessary to reattach the retina and prevent permanent vision loss.

Overall, if you are experiencing floaters or flashes of light, it is important to schedule an appointment with an ophthalmologist as soon as possible to rule out any underlying conditions and develop an appropriate treatment plan. Early detection and treatment of underlying eye conditions can help prevent permanent vision loss and improve overall eye health.
