Eye Floaters: When to Worry About Visual Disturbances - Ophthalmology

More Info

When it comes to eye floaters and visual disturbances, especially for individuals with high myopia (nearsightedness), it is essential to understand the nature of these symptoms and when they might warrant further medical evaluation.
Eye floaters are small specks or strands that drift through 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 or due to certain conditions like high myopia, the vitreous can become more liquid, leading to the formation of floaters. These floaters are usually harmless, but they can be bothersome, especially when they become more noticeable against bright backgrounds, such as a clear sky or a white wall.

In your case, you mentioned that you have been experiencing an increase in the number of floaters, which are now noticeable even indoors or while using your phone. This change can be concerning, particularly for someone with high myopia, as they are at a higher risk for retinal issues, including retinal tears or detachments. The presence of new floaters, especially if accompanied by flashes of light or a sudden increase in the number of floaters, can indicate a more serious condition that requires immediate attention.

The visual disturbances you described, such as seeing halos or faint lines around objects, could be related to several factors. These may include:
1. Vitreous Detachment: As the vitreous shrinks and pulls away from the retina, it can cause floaters and flashes of light. This is a common occurrence, especially in individuals with high myopia.

2. Retinal Issues: If you notice a sudden increase in floaters, especially if accompanied by flashes of light or a shadow in your peripheral vision, it is crucial to seek medical attention promptly. These symptoms could indicate a retinal tear or detachment, which is a medical emergency.

3. Visual Perception Changes: The perception of flickering or shimmering lights, especially against a white background, can also be related to the way your brain processes visual information. This can be exacerbated by anxiety or stress, which may heighten your awareness of these disturbances.

Given your concerns, it is advisable to monitor your symptoms closely. If you experience any of the following, you should seek immediate medical attention:
- A sudden increase in the number of floaters.

- Flashes of light in your peripheral vision.

- A shadow or curtain effect in your vision.

- Sudden changes in your vision, such as blurriness or loss of vision.

In the meantime, while waiting for your appointment, try to minimize eye strain by following the 20-20-20 rule: every 20 minutes, take a 20-second break to look at something 20 feet away. This can help reduce discomfort from prolonged screen time.

Lastly, while it is natural to feel anxious about changes in your vision, it is essential to remember that not all floaters or visual disturbances indicate a serious problem. However, given your history of high myopia, it is prudent to remain vigilant and proactive about your eye health. Regular check-ups with your eye care professional are vital to monitor any changes and ensure your eyes remain healthy.
