Eye Floaters: Causes, Symptoms, Diagnosis & Treatment

Eye floaters are small shapes, spots, or thread-like shadows that drift across your field of vision. They are especially noticeable when looking at a bright background, such as a clear sky or a white wall.

In most cases, floaters are harmless and a normal part of aging. However, sudden changes in floaters can sometimes signal a more serious eye condition.

What Causes Eye Floaters?

Floaters are usually caused by changes in the vitreous — the gel-like substance inside the eye. As we age, the vitreous becomes more liquid and tiny collagen fibers can clump together, casting shadows on the retina.

• Common causes include:

• Natural aging process

• Posterior vitreous detachment (PVD)

• Nearsightedness (myopia)

• Eye injury or trauma

• Inflammation inside the eye (uveitis)

• Diabetic eye disease

• Retinal tear or retinal detachment (serious causes)

Symptoms of Eye Floaters

Floaters may appear as:

• Small black or gray dots

• Thread-like strands

• Cobweb shapes

• Transparent squiggly lines

• Moving shadows that drift when you move your eyes

• They tend to move away when you try to focus directly on them.

When Are Floaters Dangerous?

Seek urgent eye care if you experience:

• A sudden increase in floaters

• Flashes of light

• A dark curtain or shadow in your side vision

• Sudden blurred or reduced vision

• These symptoms could indicate a retinal tear or retinal detachment, which requires immediate treatment.

How Are Eye Floaters Diagnosed?

An eye doctor will perform a comprehensive eye examination, including a dilated retinal exam to check for:

• Retinal tears

• Retinal detachment

• Vitreous changes

• Underlying eye disease

• Early diagnosis is crucial to prevent permanent vision loss.

Treatment Options for Eye Floaters

1. Observation (Most Common)

In many cases, floaters become less noticeable over time and require no treatment.

2. Vitrectomy

A surgical procedure that removes the vitreous gel. This is usually reserved for severe cases due to associated risks.

3. Laser Treatment (Selective Cases)

Laser vitreolysis may reduce certain floaters, but it is not suitable for everyone.

Can Eye Floaters Be Prevented?

• Age-related floaters cannot be prevented. However, you can reduce the risk of serious complications by:

• Having regular comprehensive eye exams

• Managing diabetes and other health conditions

• Protecting your eyes from injury

• Seeking immediate care if symptoms suddenly change

When to Book an Eye Exam
