the Causes of Increasing Floaters in Your Vision - Ophthalmology

More Info

---

Floaters, or "muscae volitantes," are small specks or strands that drift through your field of vision. They are often more noticeable when looking at a plain background, such as a clear sky or a white wall. The experience of increasing floaters can be concerning, especially if you notice that a particular floater is becoming longer or more pronounced.
The primary cause of floaters is the natural aging process of the eye. As we age, the vitreous humor, a gel-like substance that fills the eye, begins to liquefy and shrink. This process can lead to the formation of clumps or strands within the vitreous, which cast shadows on the retina, resulting in the perception of floaters. In individuals with high myopia (nearsightedness), like yourself, the risk of developing floaters can be higher due to the structural changes in the eye.

However, an increase in floaters, especially if they are becoming more prominent or if you experience flashes of light, could indicate potential underlying issues. Here are some possible causes for the changes you are experiencing:
1. Vitreous Detachment: As the vitreous shrinks, it can pull away from the retina. This is known as posterior vitreous detachment (PVD). While PVD is common and often harmless, it can sometimes lead to more serious conditions, such as retinal tears or detachment.

2. Retinal Issues: In some cases, an increase in floaters can be associated with retinal problems. This includes retinal tears or detachment, which can occur when the vitreous pulls on the retina too forcefully. Symptoms of retinal detachment may include a sudden increase in floaters, flashes of light, or a shadow or curtain effect over your vision.

3. Inflammation: Conditions such as uveitis (inflammation of the uvea) can also lead to an increase in floaters. Inflammation can cause debris to accumulate in the vitreous, resulting in more noticeable floaters.

4. Hemorrhage: In some cases, bleeding into the vitreous cavity (vitreous hemorrhage) can occur, leading to a sudden increase in floaters. This can happen due to various reasons, including diabetic retinopathy or trauma.

5. Other Eye Conditions: Certain eye diseases, such as diabetic retinopathy or age-related macular degeneration, can also contribute to the perception of floaters.

Given your description of a specific floater becoming longer, it is essential to consult with an eye care professional. They can perform a thorough examination, including a dilated eye exam, to assess the health of your retina and vitreous. This is crucial, especially since you mentioned feeling overwhelmed by the presence of floaters.

In the meantime, here are some recommendations:
- Monitor Symptoms: Keep track of any changes in your vision, such as new floaters, flashes of light, or any loss of peripheral vision. If you notice any of these symptoms, seek immediate medical attention.

- Regular Eye Exams: Ensure you have regular eye check-ups, especially given your history of high myopia. This will help in early detection of any potential issues.

- Stay Informed: Understanding that floaters are common and often benign can help alleviate some anxiety. However, being vigilant about changes is essential.

In conclusion, while floaters are typically harmless, an increase in their number or changes in their appearance warrants a professional evaluation to rule out any serious conditions. Your eye health is paramount, and addressing your concerns with an eye care specialist will provide you with the best course of action.
