Floaters and Flashing Lights: When to Seek Help - Ophthalmology

More Info

Hello! Thank you for your question regarding floaters and flashing lights in your vision. It’s understandable to be concerned about these symptoms, especially since you have a history of floaters and have undergone retinal examinations in the past.

Floaters, or "muscae volitantes," 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, the vitreous can become more liquid and may pull away from the retina, leading to the perception of floaters. This is generally a benign condition, but it can sometimes indicate more serious issues, particularly if accompanied by other symptoms.

Flashing lights, on the other hand, can occur when the vitreous pulls on the retina or when there is irritation to the retina itself. This can happen due to vitreous detachment, which is common and usually not serious, but it can also be a sign of retinal tears or detachments, which require immediate medical attention.

Given your symptoms of increased floaters, occasional flashes of light, and the sensation of shadows in your vision, it is essential to monitor these changes closely. The fact that your floaters have worsened and you are experiencing new visual disturbances, such as shadows that disappear when you look up, could indicate a need for further evaluation. While you mentioned that you recently received a vaccine and may have difficulty going for an examination, it is crucial to prioritize your eye health.

If your symptoms persist or worsen, I recommend seeking an eye examination as soon as possible. You can choose to visit either a hospital or a smaller clinic, depending on what is more convenient for you. However, if you experience sudden changes in vision, such as a significant increase in floaters, new flashes of light, or a curtain-like shadow over your vision, you should seek immediate medical attention, as these could be signs of a retinal tear or detachment.

In the meantime, here are a few points to consider:
1. Avoid Strain: Limit activities that require intense focus, such as prolonged screen time, especially if you notice that your symptoms worsen during these activities.

2. Keep a Symptom Diary: Document when you experience these symptoms, their duration, and any associated activities. This information can be valuable for your eye care provider.

3. Stay Informed: Educate yourself about the symptoms of retinal detachment, which include sudden flashes of light, a sudden increase in floaters, or a shadow or curtain over your vision.

4. Follow Up: Once you are able to visit a healthcare provider, ensure you communicate all your symptoms clearly. A thorough examination, including a dilated fundus exam, will help determine the cause of your symptoms.

In summary, while floaters and occasional flashes can be common and benign, the recent changes in your symptoms warrant a professional evaluation. Please prioritize your eye health and seek an examination when possible. Your vision is important, and early detection of any potential issues can lead to better outcomes. Take care!
