What To Do About Annoying Eye Floaters

Visual Distractions

Pin

With better functioning in youth, eyes are remarkable focusing mechanisms. Over time, muscles that aid in focusing weaken. Corrective lenses become common. But eyes remain sensitive to abnormal interference. Mild floaters are normal, and may resolve on their own.

To prevent floaters, try to keep your fingers from your eyes, particularly when sleeping. You can wear a sleep mask if necessary. Do not rub them too vigorously. Avoid contact sports that can damage eyes. There is a cause of concern if you notice a sudden increase in the amount of floaters, if part of your vision appears blocked by a dark curtain, or if you observe disturbing flashes of light. In such cases, contact your doctor immediately to save your vision.

Floaters
Simulation of floaters within left eye while looking at sky: Floaters may resemble black or gray blobs, specks, strings, or cobwebs that drift about when you move your eyes and appear to dart away when you try to look at them directly. Ambient light can either diminish or accentuate appearance.

Sometimes, what you assume is a floater may be an eyelash or eyebrow hair hanging in your field of view. Removal of the lash rectifies the problem. If there is no irritation but something keeps blocking your sight, blink several times while looking straight ahead. If it moves, it could be other debris—perhaps mucus—on the surface. If it remains in the same relative position, though seeming to dart back and forth as you look from side to side, the cause it likely one or more internal floaters.

Managing Eye Floaters

Floaters can range in appearance from dots that are barely noticeable to what might be seem like insects or cobwebs constantly hovering in front of your eye. White or light backgrounds make them most apparent. If they interfere with focus or reading, express your concerns to an ophthalmologist or optometrist. During the exam, they may dilate your eyes with drops, making it possible for the doctor to look inside. There are also various machines that can create images of your eye interior without dilation.

An optometrist or ophthalmologist wants to rule out retinal detachment, macular degeneration, or glaucoma. With age or trauma, the translucent vitreous membrane can begin separating from the retina. This process, called posterior vitreous detachment (PVD), can take 3 months or longer. It may get worse, in terms of distracting floaters, before it gets better. A followup exam is usually required in 6–8 weeks, unless there are more severe signs of retinal detachment, which has similar symptoms. Eventually, gravity should pull the membrane down out of view. The membrane may also dissolve over time.

Retinal detachments are usually painless and are not associated with headaches. There are very rare causes of retinal detachment associated with systemic diseases such as hypertension that may have associated headaches. Transient diminished vision in one eye with migraines is generally unrelated to floaters. It may be a condition known as retinal migraine. This has constricting blood vessels as its cause. It that may be hereditary. If frequent, treatment is the same as other migraines.

For excessive floaters that interfere with daily activities, an operation called a vitrectomy is possible. In this procedure, the entire vitreous gel contents of an eye is replaced with saline. Alternatively, a few doctors have the skill and equipment to target specific floaters with laser vitreolysis. There is a chance that the laser may disperse larger floaters into smaller ones rather than vaporize them. In cases where dozens of floaters are visible, a laser is not the best option.

Differential

Retinal detachment is a disorder of the eye in which the retina separates or breaks from the layer underneath. Symptoms include an increase in the number of floaters, flashes of light, and worsening of the outer part of the visual field.

Macular degeneration, also known as age-related macular degeneration (AMD or ARMD), is a medical condition which may result in blurred or no vision in the center of the visual field. There is no cure, but dietary supplements may slow progression in those who already have the disease.

It is thought that most cases of glaucoma (although not all) are caused or enabled by an increase in intraocular pressure. Pressure increases either when too much aqueous humor fluid is produced or by decreased aqueous humor outflow.

The D-Eye Retina macro-lens adapter (ophthalmoscope) for iPhone allows eyecare professionals to photograph or make videos of the inner eye. Within seconds, an ophthalmologist can diagnose a range of eye disorders without dilating pupils.

As you can see, eye care professionals do more than prescribe and fit eyewear. When getting eye exams, speak up about issues that concern you, even if extra tests may cost more. What will you do about chronic floaters? In most cases nothing. For patients that undergo vitrectomy, the road to recovery is several months.
