Retinal Issues: What to Know About Floaters and Visual Disturbances - Ophthalmology

Hello! Thank you for your questions regarding floaters and visual disturbances, especially in the context of your high myopia. It’s understandable to be concerned about changes in your vision, particularly with a history of eye conditions. Let’s address your questions one by one.

1. What does "more floaters" mean?
When your doctor mentions that floaters may increase, they are referring to the potential for more visible spots or strands in your field of vision. Floaters are typically caused by changes in the vitreous gel inside the eye, which can become more liquid and allow tiny clumps of gel or cells to cast shadows on the retina. An increase in floaters can mean that you might notice more of these shadows, which can vary from a few additional specks to a significant increase that could resemble a swarm of flies or a curtain of shadows. If you experience a sudden increase in floaters, especially if accompanied by flashes of light or a shadow in your peripheral vision, it’s crucial to seek immediate medical attention, as these could be signs of retinal detachment.

2. Seeing black and white wavy patterns:
The phenomenon you described, where you see wavy patterns or visual distortions on a white wall, is often related to visual disturbances that can occur due to various reasons, including vitreous changes or even migraine auras. These patterns are typically not a cause for alarm if they are transient and resolve quickly, as you mentioned they did after a few blinks. However, if these visual disturbances persist or are accompanied by other symptoms such as flashes of light or a sudden increase in floaters, it’s essential to consult your eye care professional. While these symptoms can be benign, they can also indicate more serious issues, such as retinal tears or detachments, particularly in individuals with high myopia.

3. Can rubbing your eyes cause retinal tears or detachment?
Generally, gentle rubbing of the eyelids should not cause retinal tears or detachments, especially if you are not applying pressure directly to the eyeball. However, if there is a history of vitreous detachment or other eye conditions, it’s advisable to be cautious. Excessive or forceful rubbing can potentially lead to complications, especially in individuals with pre-existing eye conditions. If you experience any sudden changes in vision after such an incident, it would be wise to have your eyes examined.

In summary, while floaters and visual disturbances can be common, especially in individuals with high myopia, it’s essential to monitor any changes closely. Regular eye examinations are crucial, particularly if you notice an increase in floaters, new visual disturbances, or any other concerning symptoms. Always err on the side of caution and consult your eye care provider if you have any doubts or if your symptoms change. Maintaining good eye health through regular check-ups and being aware of your symptoms can help ensure that any potential issues are addressed promptly. Thank you for your thoughtful questions, and I hope this information helps clarify your concerns!
