Sudden Increase in Eye Floaters May Signal Retinal Disease, Doctor Warns

Sudden floaters in vision, often described as black dots or lines that seem to buzz around, are a common experience known as "floaters." While most cases are linked to the natural aging process of the eye's vitreous humor, doctors urge caution.

According to Dr. Tu Yu-wei of Hanmingtang Traditional Chinese Medicine Clinic, the vitreous humor, which is gel-like, gradually liquefies, condenses, and shrinks with age. This can cause individuals to perceive small black dots, lines, or cobweb-like images in their field of vision, especially against bright backgrounds like the sky or white walls. People with high myopia may also experience vitreous degeneration earlier.

Most floaters are related to the natural degeneration of the eye's vitreous humor, but if the black spots suddenly increase significantly, especially with flashes of light, visual field defects, or decreased vision, it could be a warning sign of eye diseases such as retinal tears, and you should seek an ophthalmologist examination as soon as possible.

While these floaters are often benign, Dr. Tu emphasizes that they should not be ignored. A sudden, significant increase in floaters, particularly if accompanied by flashes of light, blind spots, or a decline in vision, could signal serious eye conditions like a retinal tear. In such cases, prompt examination by an ophthalmologist is crucial, rather than simply attributing the symptoms to aging.

The primary task is to undergo an eye examination first to confirm whether there are acute eye diseases.

Traditional Chinese Medicine refers to floaters as "cloudy mist moving in the eyes." Treatments can vary based on individual constitution and symptoms, focusing on clearing the liver, benefiting the eyes, or nourishing the kidneys. In some instances, methods to promote fluid circulation or blood flow may be employed to improve circulation in the head and eye area. However, Dr. Tu stresses that a thorough eye examination to rule out acute conditions like retinal tears should be the first step before considering any complementary treatments.

For daily maintenance, Dr. Tu recommends limiting high-sugar and high-oil diets, ensuring adequate sleep, and taking regular breaks during prolonged use of phones or computers. Caution is advised with heat compresses around the eyes or neck, ensuring the temperature and pressure are not excessive and do not directly press on the eyeball. The key takeaway, he reiterates, is not to rush to eliminate floaters but to first ascertain if they are merely a sign of vitreous degeneration. Any accompanying warning signs like flashes, vision loss, or blind spots necessitate immediate medical attention from an eye specialist.

The focus is not on rushing to eliminate the floaters, but on first confirming whether it is just simple vitreous degeneration; once accompanied by warning signs such as flashes, visual field defects, or decreased vision, seek immediate diagnosis and treatment from an ophthalmologist.
