Floaters and Vitreous Degeneration: Symptoms and Concerns - Ophthalmology

More Info

---

Floaters and flashes of light in the vision can be concerning symptoms, especially when they appear suddenly or in combination. Based on your description, it seems you are experiencing a range of visual disturbances, including floaters, flashes, and transient light spots. Let's address your concerns systematically.

1. Are these symptoms just floaters and vitreous degeneration?
Floaters are typically small particles or strands that float in the vitreous humor of the eye, which is the gel-like substance filling the eye. They are often harmless and can be a normal part of aging or vitreous degeneration. The flashes of light you describe, particularly when moving your eyes, can also be related to vitreous changes. When the vitreous pulls away from the retina, it can stimulate the retina and cause these flashes. However, the presence of new floaters, especially if they are accompanied by flashes or changes in vision, warrants a thorough examination by an eye care professional.

2. Could eye fatigue be causing these symptoms?
Eye fatigue can certainly contribute to visual disturbances, especially if you have been straining your eyes or spending long periods focusing on screens or reading. However, while fatigue can exacerbate existing symptoms, it is unlikely to be the sole cause of new floaters or flashes. It's essential to differentiate between symptoms caused by fatigue and those that may indicate a more serious condition.

3. Could this be a precursor to retinal detachment?
The combination of new floaters and flashes can be a warning sign of retinal detachment or a retinal tear. If you experience a sudden increase in floaters, flashes, or a shadow or curtain effect in your vision, it is crucial to seek immediate medical attention. While not all cases of floaters and flashes lead to retinal detachment, these symptoms should not be ignored, especially if they are new or worsening.

4. Are the light streaks or spots seen when closing your eyes a form of visual persistence?
The light streaks or spots you see when closing your eyes could be related to a phenomenon known as "visual persistence" or "phosphene." This occurs when the retina is stimulated, either by pressure or movement, even in the absence of light. While this is generally benign, if it occurs frequently or is accompanied by other visual changes, it should be discussed with your eye doctor.

In summary, while floaters and flashes can often be benign, your recent symptoms, especially the combination of new floaters, flashes, and transient light spots, should be evaluated by an eye care professional. An eye examination, including a dilated fundus exam, can help determine the cause of your symptoms and rule out any serious conditions like retinal detachment. If you notice any sudden changes in your vision, such as a significant increase in floaters, flashes, or any loss of vision, seek immediate medical attention. Early detection and treatment are crucial in preserving your vision and addressing any underlying issues.
