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.

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.

What tests should be done at the hospital for floaters?

To diagnose floaters, hospitals primarily use ultrasound B-scans, which are the most objective and non-invasive examinations, providing insights into the condition of the vitreous body. Floaters can be either physiological or pathological. Physiological floaters generally do not affect vision, and addressing them usually involves rest and proper eye care. If needed, treatment options may include Amniotic Iodine eye drops or oral intake of Lecithin Iodine complexes. However, if the floaters are pathological, proactive eye examinations and rigorous treatment are necessary. In severe cases, surgical intervention might be considered to preserve vision, as the causes of pathological vitreous opacities are diverse.

Severe cases of floaters can lead to what outcomes?

Floaters, also known as vitreous opacities, can be divided into physiological and pathological types. Physiological vitreous opacities, even if severe, do not affect vision, but simply result in a higher number of floating objects seen in the field of vision. Pathological vitreous opacities, on the other hand, can significantly decrease vision and may even lead to blindness. Therefore, during an examination, it is important to first check the uncorrected visual acuity, corrected visual acuity, intraocular pressure, ocular B-ultrasound, and fundus photography. If there are any underlying eye conditions, they should be actively treated to potentially restore vision as soon as possible. It is also advisable to ensure adequate rest, reduce close-up activities, and maintain a light diet.

The difference between transparent and black flying mosquito disease

Floaters appear before the eyes as either transparent or opaque, black objects—it's a matter of severity, generally not affecting vision. Floaters can be classified as physiological or pathological. Physiological floaters generally require only rest, reducing close-up tasks, and avoiding eye fatigue. Treatments can include using Ametiodine eye drops and Sodium Hyaluronate eye drops. If the floaters are pathological, one should visit an ophthalmologist for examinations such as an ultrasound (B-scan), intraocular pressure test, uncorrected visual acuity, corrected visual acuity, and fundus photography. Active treatment and regular follow-ups should be pursued, with close attention to vision changes. (Please use medication under medical supervision.)

Can flying mosquito disease be treated with a hot compress on the eyes?

Floaters can completely be treated with warm compresses on the eyes, but if the purpose is to treat floaters, then it is meaningless because warm compresses have no effect on the treatment of floaters. Floaters can be divided into physiological floaters and pathological floaters. Physiological floaters do not affect vision at all; one cannot see clearly in dark places, but can see floaters in bright conditions. In such cases, it is only necessary to ensure adequate rest, use eyes properly, and appropriately use medicines like Ammonium Iodide Peptide Eye Drops, or Phosphatidylcholine Complex Iodine Tablets. If it is a pathological vitreous opacity, one should visit the ophthalmology department for thorough examinations and active treatment to strive for the restoration of vision. (Please use medication under the guidance of a physician.)
