Floaters and Yellow Bumps in Your Eye: What You Need to Know - Ophthalmology

More Info

---

Floaters, or "flying mosquitoes," are a common visual phenomenon that many people experience, especially as they age. They are typically caused by changes in the vitreous humor, the gel-like substance that fills the eye. As we age, the vitreous can become more liquid and may pull away from the retina, leading to the formation of floaters. These appear as small dots, lines, or cobweb-like structures that drift across your field of vision. The fact that you have been experiencing floaters for several years suggests that this is a benign condition, especially if you have had regular eye examinations that have ruled out more serious issues like retinal detachment.

The recent observation of seeing green-yellow spots when moving from dark to bright areas could be related to a phenomenon known as "visual afterimages" or "phosphene." This occurs when the photoreceptors in your retina are temporarily overstimulated, leading to the perception of colors or shapes that are not actually present. This is generally harmless and can happen to anyone, especially in conditions of sudden light changes. However, if these visual disturbances become more frequent or are accompanied by other symptoms such as flashes of light or a sudden increase in floaters, it is essential to consult an eye care professional to rule out any serious conditions.

Regarding the yellow bump you mentioned on your lower eyelid, this could be a condition known as a chalazion or a sebaceous cyst. A chalazion occurs when a meibomian gland (a type of oil gland in the eyelid) becomes blocked, leading to a painless lump. These bumps are usually harmless and may resolve on their own, but if they become bothersome or do not improve, treatment options such as warm compresses or, in some cases, minor surgical intervention may be necessary.
It’s important to monitor any changes in your eye health. If you notice an increase in the number of floaters, changes in your vision, or if the yellow bump becomes painful or changes in appearance, you should seek an evaluation from an ophthalmologist. Regular eye exams are crucial, especially for individuals with a history of floaters or other eye conditions, as they allow for early detection and management of potential issues.

In summary, while floaters and the yellow bump you described are likely benign, staying vigilant about your eye health is essential. If you have any concerns or if your symptoms change, do not hesitate to reach out to an eye care professional for a thorough examination and peace of mind.
