Hello, this is Goyang Shinsegae Eye Clinic. Have you ever noticed small specks, insects, or thread-like shapes floating in front of your eyes during your daily activities? These shapes may appear more clearly when looking at a bright background such as a clear sky, a white wall, or a computer monitor. If they seem to move along with your gaze when you move your eyes, you may be experiencing floaters. 1. Floaters That Look Like Dots or Insects in Your Vision Floaters refer to visual symptoms in which dots, threads, dust-like particles, insects, or cobweb-like shapes appear to float in front of the eyes. Some people notice black spots moving across their vision, while others describe thin strands, cobweb-like patterns, or the sensation of small insects flying around. Another common characteristic is that these shapes seem to move when the eyes move. They are often easier to notice against bright backgrounds such as a white wall or the sky rather than in dark surroundings. Floaters themselves are relatively common. However, if the number of floaters suddenly increases or if they suddenly appear in only one eye, it is advisable to visit an ophthalmology clinic in Deogyang-gu for an examination. 2. What Causes Floaters? One of the most common causes of floaters is age-related changes in the vitreous body. The vitreous is a transparent, gel-like substance that fills the space between the lens and the retina and occupies most of the inside of the eyeball. At a younger age, the vitreous is generally clear and maintains a relatively uniform structure. As we age, however, the collagen structure within the vitreous changes, and a process called vitreous liquefaction occurs, during which water and fibrous components begin to separate. When these fibers clump together and create opacities, they can cast shadows as light passes toward the retina. These shadows may then be perceived as dots, insects, or thread-like objects floating in the field of vision. In other words, floaters are not caused by dust or debris on the surface of the eye. They occur because of structural changes within the vitreous. 3. Uveitis Can Also Cause Floaters The uvea is the middle layer of the eye and consists of the iris, ciliary body, and choroid. Inflammation of this area is called uveitis. When uveitis develops, inflammatory cells and substances produced by inflammation may enter the vitreous. These materials can interfere with the passage of light and cause floaters. Other symptoms may occur at the same time, including eye pain, redness, decreased vision, glare, or increased sensitivity to light. 4. Why Floaters Should Not Always Be Ignored Two important conditions that should be checked in patients with newly developed floaters are retinal tears and retinal detachment. A retinal tear occurs when a small hole or tear develops in the retina. If left untreated, fluid may pass through the tear and accumulate underneath the retina, potentially leading to retinal detachment. Retinal detachment occurs when the retina separates from the inner wall of the eye. Because this condition can significantly affect vision depending on its severity and progression, prompt diagnosis and appropriate treatment are important. 5. How Are Floaters Examined? A dilated eye examination is commonly performed. Eye drops are used to enlarge the pupil, allowing the ophthalmologist to examine the retina and check for peripheral retinal tears, retinal detachment, bleeding, or other abnormalities. If necessary, additional tests such as optical coherence tomography (OCT) or ocular ultrasonography may be performed to evaluate the vitreous and retinal structures in greater detail. In particular, people in their 50s and 60s or older may benefit from regular ophthalmic examinations even when they do not have noticeable symptoms. 6. Treatment Options ✅ Treatment for Retinal Tears: Laser Photocoagulation Laser photocoagulation may be used to treat a retinal tear. The laser is applied around the torn area to create adhesions between the retina and the surrounding tissue. This can help reduce the risk of the tear progressing to retinal detachment. In many cases, the procedure can be performed on an outpatient basis and is completed within a relatively short period of time. ✅ Treatment for Retinal Detachment: Vitrectomy If retinal detachment has occurred, vitrectomy may be required depending on the condition of the retina and vitreous.…
