Eye Floaters Evaluation in Seomyeon, Busan
An eye floaters evaluation checks whether spots, threads or cobwebs drifting in your vision are harmless vitreous changes or signs of a retinal tear or detachment. At Seomyeon eye clinics, it usually involves dilating drops and a thorough retina exam, sometimes with OCT or wide-field imaging, taking about 1–2 hours. Sudden new floaters with flashes or a shadow need same-day assessment.

What are eye floaters?
Floaters (비문증) are small shadows cast on the retina by clumps or strands in the vitreous, the gel that fills the eye. They are most noticeable against a bright sky or white wall. As we age, the vitreous liquefies and can separate from the retina, a common event called posterior vitreous detachment (PVD). This often causes a sudden new floater. Usually harmless, PVD can occasionally tear the retina, which can lead to retinal detachment if untreated.
Symptoms and when to see a doctor
- Same-day assessment: sudden increase in floaters, new flashes of light, a dark curtain or shadow spreading across vision, or sudden blurred vision.
- Routine check: long-standing, stable floaters that bother you.
- Highly nearsighted people and those with previous eye surgery or trauma should have new floaters checked promptly.
What happens at the clinic
- History: when floaters started, flashes, vision changes and risk factors.
- Vision and pressure check.
- Dilation: drops widen the pupils.
- Retina exam: the doctor examines the entire retina, including the far periphery, sometimes pressing gently on the eyelid to see the edges.
- Imaging: OCT or wide-field retinal photos may be used; ultrasound if the view is blocked by blood.
Treatment outlook
Most floaters need no treatment and become less noticeable over weeks to months as the brain adapts and floaters settle. If a retinal tear is found, laser or freezing treatment can seal it, usually in the clinic. A retinal detachment requires surgery. For persistent, severely disabling floaters, vitrectomy or YAG vitreolysis may be discussed, but these carry risks and are not routine.
Risks and side effects
The exam itself is safe, with temporary blur and light sensitivity from dilation. Delayed assessment of a retinal tear is the main risk. A new PVD may warrant a repeat exam a few weeks later even if the first is normal.
Choosing a clinic for floaters evaluation in Seomyeon
- Call ahead and describe symptoms; ask whether a same-day dilated exam is possible.
- Ask whether a retina specialist is available if a tear is found.
- Ask whether laser treatment for tears can be done on-site.
- Ask when a follow-up exam is recommended after a new PVD.
- Ask which warning signs should prompt you to return immediately.
After dilation
Do not drive afterwards; Seomyeon's metro links on Lines 1 and 2 make it easy to get home by train or taxi.
Key facts

- Urgent signs: sudden shower of floaters, flashes, curtain or shadow
- Exam: dilated retina exam with careful view of the periphery
- Visit time: about 1–2 hours including dilation
- Treatment: usually reassurance; laser for tears; surgery for detachment
Frequently asked questions
Are eye floaters dangerous?
Most are harmless age-related changes. However, a sudden increase in floaters, especially with flashes or a shadow, can signal a retinal tear or detachment needing urgent care.
Do eye floaters go away?
Many become less noticeable over weeks to months as they settle and the brain adapts. Some persist long term but cause no harm.
Can floaters be removed?
Vitrectomy or YAG laser vitreolysis may be considered for severe, disabling floaters, but both carry risks. Most people do not need treatment.
Why are floaters more common in nearsighted people?
Longer, nearsighted eyes have vitreous and retinal changes earlier, raising the chance of floaters, vitreous detachment and retinal tears.
Do I need a follow-up after a vitreous detachment?
Often yes. Some tears develop days to weeks after a PVD, so your doctor may recommend a repeat exam even if the first is normal.
