Floaters: When to Seek Eye Care for Sudden Changes - Ophthalmology

The phenomenon of floaters?


Hello, doctor.
I would like to ask you a question.
Around September 9th, I suddenly felt that my left eye was more prone to fatigue.
It gradually improved, but since that day, I have noticed new floaters resembling small cells in my vision.
I have had floaters for many years, and since their appearance has not changed, I have coexisted with them without any issues.
Therefore, when I noticed this new type of floater, I decided to observe it for a while.
Usually, when I am indoors using the computer or reading, they are not very noticeable, but when I go outside in bright sunlight, they become particularly prominent, although their movement is not significant.
I am a bit worried.
I have an appointment scheduled with the ophthalmology department on October 1st.
I would like to know if I should go for a retinal examination immediately or if I can wait until my appointment on October 1st.
I am concerned that there might be a sudden change in the next three days.
Thank you for your response, doctor.
My main concern is that the new floaters I have not seen before might indicate a retinal tear that needs urgent attention.
Thank you.

Hello, Student Chen: If you are constantly worried, I recommend that you get checked as soon as possible.
Early detection can help identify any issues, or if there are none, you can have peace of mind and not be troubled by these concerns every day.
Issues with the retina can only be determined after an examination, and no one can predict the changes that may occur in the coming days.

When it comes to floaters and sudden changes in vision, it's essential to understand the nature of these symptoms and when to seek medical attention. Floaters are tiny specks or strands that drift through your field of vision, often more noticeable against a bright background. They are typically caused by changes in the vitreous gel that fills the eye as we age. However, sudden changes in the number or appearance of floaters, especially if accompanied by flashes of light or a shadow in your peripheral vision, can indicate more serious conditions, such as retinal tears or detachments.

In your case, since you have a history of floaters and have noticed a sudden increase in their number and a change in their appearance, it is prudent to be cautious. The fact that you have experienced fatigue in your left eye and the new floaters appeared around the same time could suggest that there is an underlying issue that needs to be evaluated. While it is common for floaters to be benign, any sudden change warrants a thorough examination by an eye care professional.

Given that you have already scheduled an appointment for October 1st, it is generally acceptable to wait for that appointment if you are not experiencing any additional symptoms such as flashes of light, significant vision loss, or a curtain-like shadow over your vision. However, if you notice any worsening of your symptoms, such as an increase in floaters, new flashes of light, or a significant change in your vision, you should seek immediate medical attention.
It is understandable to feel anxious about the possibility of a retinal tear or detachment, especially with the new floaters. The risk of these conditions increases with age and is particularly relevant for individuals with high myopia (nearsightedness), as the vitreous gel can become more prone to pulling away from the retina.
In terms of managing your anxiety while waiting for your appointment, it may help to remind yourself that floaters are common and often harmless. Engaging in relaxation techniques, such as deep breathing or mindfulness, can also be beneficial in alleviating stress.
If you do experience any acute changes in your vision or if the floaters become more bothersome, do not hesitate to seek immediate care. Eye health is crucial, and being proactive about any changes can help ensure that any potential issues are addressed promptly.
In summary, while it is generally safe to wait for your scheduled appointment, remain vigilant for any new symptoms. If you experience any sudden changes, seek immediate evaluation. Your eye health is important, and addressing concerns early can help prevent complications.
