Understanding Eye Floaters: Causes, Symptoms, and Emergency Signs

Understanding TMJ and Eye Floaters

As we age, many people begin noticing small specks or clouds moving in their field of vision. These are known as eye floaters and are especially common for those with TMJ or temporomandibular joint dysfunction.

What Causes Eye Floaters?

Eye floaters occur when small pieces of material inside the eye break loose and drift in the gel-like fluid inside your eyes. These tiny flecks or specks seem to float or drift in your field of vision when you move your eyes.

The most common causes of eye floaters include:

• Age-related changes that cause parts of the vitreous humor to deteriorate
• Inflammation inside the eye
• Bleeding inside the eye
• Tears or detachment of the retina
• A buildup of plaque or fatty deposits

What is TMJ?

TMJ stands for temporomandibular joint dysfunction. This condition causes pain and discomfort in the temporomandibular joint that connects your lower jaw to your skull. TMJ often leads to symptoms like:

• Jaw, face, neck pain
• Clicking jaw
• Locking of the jaw
• Headaches
• Earaches or ringing ears (tinnitus)

In many cases, TMJ results from grinding or clenching your teeth which puts pressure on the joints over time. Stress and arthritis can also contribute to TMJ.

The TMJ and Eye Floater Connection

Research indicates TMJ may cause or contribute to eye issues like floaters and flashes of light. This occurs because the trigeminal nerve is connected to both the temporomandibular joint and the eyes.

The trigeminal nerve is the largest cranial nerve and is responsible for providing sensation to the face plus biting and chewing. It also helps control eye muscles and movement. TMJ inflammation or compression of this nerve can sometimes irritate the eyes or parts of the eyes like the vitreous humor.

When to See Your Doctor About Eye Floaters

In most cases, small flecks or spots moving in your field of vision are harmless results of aging. However, significant changes in eye floaters or seeing sudden flashes of light can indicate a more serious problem requiring medical attention.

You should visit your doctor or an ophthalmologist right away if you experience:

• Sudden increase in eye floaters
• New eye floaters appearing as dots, strings, clouds
• Flashes of light coming from inside the eye
• Curtain or veil covering part of your vision
• Poor nighttime vision or sensitivity to light

These types of vision changes may result from retinal tears, bleeding, or detachments. Prompt medical help can prevent permanent damage or vision loss in these cases.

Managing and Preventing Eye Floaters

While annoying, typical age-related eye floaters and spots are harmless and don't require treatment. However, the following tips can help reduce eye strain which may minimize floaters:

• Use proper lighting when reading or working on the computer
• Take frequent breaks when viewing screens or focusing visually
• Wear sunglasses outdoors to limit eye exposure
• Eat a healthy diet with leafy greens and omega-3s
• Consider supplements like lutein and zeaxanthin

Proper treatment of TMJ may also help prevent associated trigeminal nerve issues leading to eye floaters. Options include pain medication, mouthguards, physical therapy, relaxation techniques, and surgery in severe cases.

When Are Eye Floaters Serious?

For the vast majority of people, eye floaters are annoying but not serious. However, a sudden increase in spots, flecks and flashing lights can indicate a major problem in some cases.

Retinal Tears

As we age, the vitreous humor thickens and may pull away from the retina, resulting in areas of retinal thinning. This increases the risk of tears in the retina. Retinal tears then allow vitreous fluid to seep underneath the retina, causing it to detach which can lead to blindness if not treated quickly.

Retinal Bleeding

Diabetic retinopathy, vein/artery blockages and injuries can sometimes cause bleeding into the vitreous humor inside the eyes. This blood may appear as eye floaters, spots or cobwebs that block vision. Prompt laser surgery is often needed to prevent permanent vision loss.

Retinal Detachment

Retinal detachment occurs when fluid leaks through a retinal tear, allowing the retina to separate from tissue underneath. Warning signs include an increase in floaters, flashes of light, and a dark curtain or shadow overtaking part of your visual field. If not treated immediately, permanent vision loss can occur.

What About Flashes of Light?

Flashes of light inside the eye may accompany the sudden appearance of new floaters. Like floaters, flashes occur when the vitreous gel inside the eyes pulls on or rubs against the retina. This stimulation of the retina registers asstreaks or lightning flashes across your vision.

By themselves, small flashes are not necessarily dangerous. But when combined with a large increase in eye floaters or other vision changes, they indicate a potential medical emergency requiring prompt professional eye care.

When to Seek Emergency Eye Care

In a vast majority of instances, eye floaters are not vision threatening. But serious causes need to be ruled out, especially if you notice a sudden increase in spots or other drastic vision changes.

Seek emergency medical eye care promptly if you experience:

• Sudden shower or swarm of new floaters
• Flashes of light in your visual field
• Floaters along with light sensitivity or poor night vision
• Curtain, veil or shadow overtaking parts of your vision
• Decrease in peripheral or overall vision

Only a full medical eye exam by an ophthalmologist can diagnose the cause and rule out potentially blinding problems. However, immediate treatment greatly improves outcomes for conditions like retinal bleeding, holes and detachments.

Can Eye Floaters Go Away?

With age-related floaters, the spots never completely go away. But the brain learns to ignore them over time. Eventually most people hardly notice old floaters as new ones develop.

However, floaters signaling a retinal tear or detachment must be treated immediately to reattach the retina and retain vision. Laser surgery flattens the retina while draining fluid and gas injections seal retinal holes and tears.

Outlook for Most Eye Floaters

Fortunately, the outlook for most bothersome eye floaters is positive. While annoying, the brain gradually filters them out so they fade into the background.

Using proper lighting, taking visual breaks, managing health issues, and getting regular eye exams helps minimize age-related floaters. And understanding warning signs allows for prompt treatment when new floaters appear suddenly or vision changes develop.
