Common eye examinations for floaters typically include B-ultrasound of the eye, fundus photography, uncorrected visual acuity, corrected visual acuity, and intraocular pressure measurements, which help assess the extent of vitreous opacities.

If the vitreous opacities are mild, meaning they are physiological, they generally do not affect vision and don’t require special treatment. Routine rest, proper eye usage, or treatment with amino iodine peptide eye drops may suffice.

If the vitreous opacities are pathological, it is important to actively pursue medication or surgical treatments to attempt to restore some of the vision. Common pathological conditions associated with vitreous opacities include increased intraocular pressure, vitreous hemorrhage, and retinal pathology.

Does floaters need surgery?

The commonly mentioned "floaters" in ophthalmology refer to the turbidity in the vitreous body of the eyes. In most cases, this phenomenon is normal; it is a normal physiological degenerative change of the vitreal body and generally does not have much impact on vision. In such cases, surgery is not needed. However, if there is a pathological change in the eye, such as bleeding at the base of the eye, and blood flows into the vitreous body, causing turbidity, surgery can be considered if this severely affects vision.

Can teenagers get floaters?

Floater syndrome can also occur in adolescents. Floater syndrome is also known as vitreous haze. Mild vitreous haze does not affect vision, but it is more noticeable under bright light. The shapes vary, and they seem to fly in front of the eyes, typically not visible in darker environments, which means they are hard to see at night. In such cases, it is important to rest properly and use one's eyes correctly. If there is any refractive error, it should be correctly addressed with appropriate glasses. If conditions like myopia, hypermetropia, or astigmatism are not actively treated, they can lead to varying degrees of amblyopia or strabismus, thus they should be taken seriously.

Can slit lamp examination detect floaters?

Floaters generally do not require examination with a slit lamp microscope; they are examined using A-scan or B-scan ultrasonography to assess the extent of vitreous opacity, posterior vitreous detachment, and the status of the vitreous in relation to the retina. Floaters are also known as vitreous opacities and can be categorized into physiological and pathological vitreous opacities. Physiological vitreous opacities generally do not affect vision but appear as some floating objects in front of the eye, which do not change vision. These are more visible in bright light and less visible or absent in low light. If the vitreous opacity is pathological, it can affect vision and requires further ophthalmologic examination and active treatment.

Where is massage effective for floaters?

Floaters, also known as vitreous opacities, can be divided into physiological and pathological types. Massaging generally has no therapeutic effect on vitreous opacities. In cases of physiological vitreous opacities, it is important to rest, reduce close-up activities to avoid eye strain, and use treatments like amino peptide eye drops and sodium hyaluronate eye drops. Usually, physiological opacities do not affect vision. However, if the vitreous opacities are pathological and severely impact vision, one should visit an ophthalmologist for an eye examination, including tests for visual acuity, intraocular pressure, ocular ultrasonography, and fundus photography, and pursue active treatment to restore normal vision.

How to treat blurry vision and floaters?

Blurry vision and floaters should prompt an examination by an ophthalmologist. Physiological vitreous opacities generally do not affect vision, but if they do, active treatment is required. Vitreous cloudiness can also be seen in patients with refractive errors, which include myopia, hyperopia, astigmatism, and presbyopia. In these cases, correct pupil dilation and optical correction should be done. After alleviating the issues with glasses, it is important to use the eyes properly, and orthokeratology can also be used. Once the prescription stabilizes, surgical treatment can be considered. However, surgical treatment generally only relieves the refractive condition and does not solve the nature of eye surrounding issues. Hence, it is crucial to use the eyes correctly and be cautious of further increase in the prescription.
