Floaters and Flashing Lights: When to Seek Help - Ophthalmology

More Info

---

Floaters and flashing lights in your vision can be concerning symptoms, especially if they have developed recently. It's important to understand what these symptoms might indicate and when to seek medical help.

Understanding Floaters and Flashing Lights
Floaters are small specks or strands that drift through your field of vision. They are usually caused by changes in the vitreous gel that fills the eye, which can become more liquid and form clumps as we age. This is a common occurrence and often harmless. However, if you notice a sudden increase in floaters, especially if accompanied by flashes of light, it could indicate a more serious condition, such as retinal detachment.

Flashing lights, or photopsia, can occur when the vitreous gel pulls on the retina, causing it to send signals to the brain that are perceived as flashes of light. This can happen during activities that involve rapid movement or changes in position, such as playing basketball, as you mentioned. The flashes you experience lasting for 3-5 minutes and occurring during specific activities could be related to this vitreous tugging on the retina.

When to Seek Help
You should seek immediate medical attention if you experience any of the following:
1. Sudden Increase in Floaters: If you notice a sudden increase in the number of floaters, especially if they are accompanied by flashes of light.


2. Flashes of Light: If the flashes become more frequent or intense, or if they occur outside of activities that typically trigger them.

3. Loss of Peripheral Vision: If you notice a shadow or curtain effect in your vision, which could indicate retinal detachment.

4. Changes in Vision: Any sudden changes in your vision, such as blurriness or distortion, should be evaluated by an eye care professional.

5. Seeing a White Patch: The white patch you see when you close your eyes could be related to the way your brain processes visual information, but if it persists or is accompanied by other symptoms, it warrants further investigation.

Surgical Considerations
Surgery for floaters or flashing lights is typically considered only when these symptoms are associated with significant vision loss or if they severely impact your quality of life. Procedures like vitrectomy, which involves removing the vitreous gel, can be performed, but they come with risks and are not always necessary. Your eye doctor will assess your specific situation and determine if surgery is appropriate based on the severity of your symptoms and the underlying cause.

Conclusion
It's understandable to feel anxious about these symptoms, especially if they are new and concerning. The best course of action is to schedule an appointment with an eye care professional who can perform a thorough examination, including a dilated fundus exam, to assess the health of your retina and vitreous. Early detection and treatment of any potential issues can help prevent more serious complications, such as retinal detachment. Remember, while floaters and flashes can be common, any significant changes in your vision should always be taken seriously.
