Floaters and Eye Health: Risks and Symptoms Explained - Ophthalmology

More Info

---

Floaters, or "flying mosquitoes" as they are colloquially known, are a common visual phenomenon that many people experience, particularly as they age. These floaters appear as small spots, lines, or cobweb-like structures that drift across your field of vision. 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 perception of floaters.
Your observation that the floaters you see are mostly blurred lines is quite normal. Floaters can vary in shape and size, and they may appear more pronounced against bright backgrounds, such as a clear sky or a white wall. If you find that the floaters are becoming more frequent or bothersome, it is advisable to consult an eye care professional for a thorough examination.
Regarding your concern about small text on your phone, it could be attributed to a combination of factors. If you have a history of myopia (nearsightedness), it is possible that your prescription has changed, making it more difficult to see small text clearly. Additionally, prolonged screen time can lead to digital eye strain, which may exacerbate visual discomfort. Symptoms of digital eye strain include blurred vision, dry eyes, and headaches. If you suspect that your myopia has worsened, it would be prudent to have your eyes checked by an optometrist or ophthalmologist.

As for your previous use of corticosteroids, it is important to note that long-term use of these medications can increase the risk of developing certain eye conditions, including glaucoma and cataracts. However, since you have not used them for 8 to 9 years, the risk may be significantly reduced, especially if you have not experienced any symptoms related to these conditions. Glaucoma is often asymptomatic in its early stages, so regular eye exams are crucial for early detection. Symptoms of glaucoma can include peripheral vision loss, seeing halos around lights, and eye pain. Cataracts typically present as cloudy or blurry vision, difficulty with night vision, and sensitivity to light.

In summary, floaters are generally a benign condition, but any sudden increase in floaters, especially if accompanied by flashes of light or a shadow in your peripheral vision, warrants immediate medical attention as these could be signs of retinal detachment. Regular eye examinations are essential, particularly if you have a history of eye conditions or have used medications that may affect eye health. Maintaining good eye health practices, such as taking breaks from screens, ensuring proper lighting while reading, and wearing appropriate corrective lenses, can help mitigate some of the visual discomfort you may be experiencing. Always consult with your eye care provider for personalized advice and treatment options tailored to your specific needs.
