ENVitreous floaters are threads, dots and cobwebs drifting across your vision, most visible against a bright background. People are told «it is age, you will get used to it», while the floaters get in the way of reading and driving. That is what they arrive with.
This page explains where these opacities come from, when they are dangerous, what is examined and which options are seriously discussed in the treatment of vitreous floaters in Germany. For eye care in general, see eye hospitals in Germany.
Where floaters come from
Floaters are shadows of thickened strands inside the vitreous, the clear gel that fills the eye. With age the gel loses water, which collects in pockets, and the gel separates into fibres whose shadows fall on the retina, the light-sensitive layer at the back of the eye. Those shadows are the floaters.
The commonest scenario is posterior vitreous detachment: the gel pulls away from the retina, and a large ring or «spider» appears that is particularly noticeable. This is not a retinal disease, but the risk of a retinal tear is at its highest exactly at that moment.
Other causes are short-sightedness, in which all this starts earlier, past inflammation inside the eye, bleeding into the vitreous in diabetes, and injury. With bleeding or inflammation it is the cause that is treated, not the floaters. Diseases of the retina are covered on the page on retinal treatment in Germany.
When floaters mean an urgent examination
An urgent examination is needed after a sudden shower of new floaters, flashes of light, a dark curtain or a missing part of the visual field, or a sudden drop in vision. These are signs of a possible retinal tear or detachment: the eye has to be examined within hours to a day, wherever you are, not in two weeks abroad.
If the floaters have been there a long time, are not changing and come without flashes, the situation is not urgent. Then a trip can be planned properly, with a full work-up.
What a German eye hospital looks at
A German eye hospital checks visual acuity and examines the back of the eye through dilated pupils, always in both eyes. The peripheral retina is examined through a special lens; an ultrasound scan of the eye and OCT of the macula, a painless cross-section image of the retina’s centre, complete the work-up. With diabetes or after an injury, the doctor adds further tests.
Why, if «the floaters are obvious anyway»? The point is not to describe the opacities but to rule out a retinal tear, find the cause and judge whether the complaints really come from the vitreous rather than the macula or an early cataract, a clouding of the lens. See also the neighbouring page on macular degeneration treatment.
What is offered: observation, laser, vitrectomy
What is offered most often is observation, which is treatment too and in most cases the main option. Over time the opacities often settle and the brain stops noticing them. The doctor explains which symptoms to watch for and when to come back.
Laser treatment of floaters, YAG vitreolysis, is an outpatient procedure that does not suit everyone: it is discussed mainly for a single large opacity away from the central zone and not close to the retina or lens. The effect can be partial, as the opacity more often shrinks than disappears, and specialists assess the method differently.
Vitrectomy is an operation in which the vitreous is removed and replaced with a solution. It is discussed only when the floaters genuinely interfere with life, and always with its risks: a cataract forming sooner in an eye with its natural lens, retinal detachment and, rarely, infection. A peer-reviewed review on managing symptomatic floaters sets out both treatments and their risks.
Who does this
This is the field of retina and vitreous surgeons in eye hospitals. Among AlenMed’s partners is the Herzog Carl Theodor Eye Clinic in Munich: its lead physician, Prof. Christos Haritoglou, is a surgeon for retinal and vitreous disease, and Prof. Maximilian Schultheiß sees patients there with the same profile.
In practice the decision «operate or watch» is taken by someone who operates on retinas themselves, so a second opinion about vitrectomy is worth getting from exactly such a doctor. Choosing one is covered on the page about an ophthalmologist in Germany.
Frequently asked questions
Are vitreous floaters dangerous?
Usually not: age-related opacities do not threaten sight, and most people need no treatment. It is different when many floaters appear suddenly with flashes, a dark curtain or a sudden drop in vision: that can mean a retinal tear or detachment, and the eye must be examined within hours to a day.
Do floaters go away on their own?
Often they become much less noticeable, as the opacities settle and the brain stops paying attention to them. Once a retinal tear has been ruled out, doctors usually advise waiting, although floaters do not always disappear. If they suddenly increase or flashes appear, the eye should be checked again at once.
Can floaters be removed with a laser?
Sometimes a floater can be made smaller, but not for everyone. YAG vitreolysis is discussed mainly for a single large opacity away from the central zone; the opacity more often shrinks than disappears, and specialists assess the method differently. Whether it fits is decided only after a full eye examination.
When is vitrectomy considered?
Rarely: when floaters genuinely interfere with life, for example with reading or work, and do not fade over time. The decision always weighs the risks: cataract, retinal detachment and, in rare cases, infection. A second opinion is therefore worth seeking from a surgeon who operates on retinas.
How AlenMed arranges the trip
AlenMed starts with the documents: the ophthalmologist’s report, OCT and ultrasound files, and details of short-sightedness, diabetes and past eye surgery go to the clinic. The doctor answers whether a trip is needed, what must be repeated and whether one visit is enough. Then come a written estimate, a visa invitation, appointments and an interpreter at consultations.
Plan for the practical side too: after a dilated examination you cannot drive for several hours and bright light is uncomfortable, so keep that day free. Also allow time to go through the report and have it translated for your doctor at home.
