Pathological floaters assessment?


Hello, doctor.
How can I distinguish whether the number of floaters is considered many or few? Recently, I've noticed an increase in floaters, but it's not excessive.
However, I had an examination two days ago, and everything was fine.
Now, I feel like there are a few more.

Hello: 1.
Monitor your vision: Floaters are typically caused by floating objects within the eye, which may appear as lines, spots, or cobwebs.
If you notice changes in your vision, it may lead to an increased perception of floaters.
2.
Pay attention to lighting conditions: Floaters are often more noticeable against bright backgrounds, such as a white wall or a clear blue sky.
If there have been recent changes in your environment's lighting, this may contribute to the perception of more floaters.
3.
Observe frequency and duration: Floaters are usually persistent and frequently appear in your field of vision.
If you feel that their frequency has increased or that they linger longer in your sight, this may indicate that you are experiencing more floaters.
4.
Be aware of other symptoms: Sometimes, floaters may be accompanied by other visual disturbances or eye discomfort, such as eye strain, blurred vision, a sensation of pressure in the eyes, or headaches.
If you experience these symptoms simultaneously, it is advisable to seek an evaluation from an ophthalmologist as soon as possible.
Most importantly, if you feel concerned or troubled, or if the floaters become prominent and persistent, it is best to have an eye examination.

More Info


When it comes to floaters in your vision, it's important to understand that they are a common occurrence, especially as we age. Floaters are tiny specks or strands that drift through your field of vision, often appearing as small dots, lines, or cobweb-like shapes. They are caused by changes in the vitreous gel that fills the eye, which can become more liquid and allow tiny fibers to clump together, casting shadows on the retina.

To determine the severity of floaters, consider the following factors:
1. Sudden Increase in Floaters: If you notice a sudden increase in the number of floaters, especially if accompanied by flashes of light or a shadow in your peripheral vision, this could be a sign of a more serious condition, such as a retinal tear or detachment. In such cases, it is crucial to seek immediate medical attention.

2. Impact on Vision: Assess whether the floaters are affecting your daily activities. If they are becoming distracting or obstructing your vision significantly, this may indicate a need for further evaluation. Floaters that interfere with your ability to read, drive, or perform tasks can be more concerning.

3. Duration and Consistency: Take note of how long the floaters have been present and whether they are consistent or fluctuating. Floaters that appear suddenly and remain constant may warrant a closer look by an eye care professional.

4. Associated Symptoms: Pay attention to any accompanying symptoms. If you experience flashes of light, a curtain-like shadow over your vision, or significant changes in your visual field, these could be signs of retinal issues and should prompt an immediate visit to an eye specialist.

5. Regular Eye Exams: Since you mentioned that you recently had an eye exam and everything was normal, it’s reassuring. Regular check-ups are essential, especially if you have a history of eye conditions or are at higher risk due to factors like high myopia (nearsightedness). Your eye doctor can monitor any changes in your floaters over time and provide guidance on when to be concerned.

6. Personal Perception: Ultimately, your perception of the floaters matters. If you feel that the floaters are increasing or becoming bothersome, it’s always best to consult with your eye care provider. They can perform a thorough examination, including a dilated eye exam, to assess the vitreous and retina for any underlying issues.

In summary, while floaters are often benign and a normal part of aging, any sudden changes or associated symptoms should not be ignored. Regular eye exams and open communication with your eye care professional are key to maintaining your eye health and addressing any concerns you may have about floaters or other visual disturbances. If you feel that your floaters are increasing or affecting your quality of life, don’t hesitate to seek further evaluation.
