Eye Floaters: Causes, Treatment, and Genetic Concerns - Ophthalmology

Share to:

Dr. Huang, may I ask you a question?


Dr.
Huang: Hello! I have been experiencing 2 to 3 black spots in my right eye and dryness and discomfort after wearing contact lenses for about a year.
I consulted the retina department at an ophthalmology clinic in a hospital in the northern part of Taiwan.
After performing dilation and eye movement tests, the doctor casually mentioned that I have eye floaters and mild inflammation, attributing the black spots to a thin vitreous body.
He prescribed me anti-inflammatory eye drops but did not provide further explanation.
He only advised me to return if the black spots suddenly increased or if I experienced eye pain.
I am not satisfied with the doctor's handling and response, so I would like to use your medical consultation service for further understanding.

The 2 to 3 black spots have been present for about a year, and they move in the direction of my eye movement.
Could this be due to a thin vitreous body or vitreous opacities? What impact does the condition of the vitreous body have on the eyes? Is there a connection between this and retinal detachment or floaters? Regarding the eye floaters, should they be surgically removed, or is there another form of medication available? My grandmother experienced gradual vision loss leading to blindness around the age of 50.
Is there a concern about hereditary factors? Thank you for taking the time to address my concerns amidst your busy schedule.
I appreciate your help!

Subject: Many Issues.
Explanation: This is a type of floaters caused by vitreous opacity.
In this type of floaters, they move along with the eye's movement; when the eye is still, the floaters also remain still, which is benign and can be ignored.
However, if the floaters are constantly moving regardless of eye movement, this symptom is associated with retinal detachment and requires immediate medical attention.
Additionally, if eye stones cause a sensation of movement in the eye, they need to be removed.
Furthermore, if your grandmother's blindness is due to glaucoma, it may have a hereditary component.

Hello! Thank you for your detailed inquiry regarding your eye health concerns, particularly about the presence of floaters and the implications of vitreous changes. I understand that you are experiencing anxiety due to the symptoms you are facing, and I will do my best to provide you with a comprehensive overview of the situation.

Understanding Eye Floaters: Causes and Implications
Floaters, or "muscae volitantes," are small spots or shapes that appear in 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 formation of floaters. This process is known as vitreous degeneration. The presence of 2-3 black dots that move with your eye movements is consistent with typical floaters, which can be more noticeable against bright backgrounds.

Vitreous Changes and Their Impact
The vitreous humor's condition can significantly affect your vision. When it becomes less gel-like and more liquid, it can lead to an increase in floaters. In some cases, if the vitreous pulls away from the retina too forcefully, it can cause a retinal tear or detachment, which is a serious condition requiring immediate medical attention. However, if your eye examinations have shown no signs of retinal issues, it is likely that your floaters are benign.

Connection to Retinal Detachment and Other Conditions
While floaters themselves are usually harmless, they can sometimes be associated with more serious conditions, such as retinal detachment. Symptoms of retinal detachment include a sudden increase in floaters, flashes of light, or a shadow or curtain over your vision. If you experience any of these symptoms, it is crucial to seek immediate medical attention.

Eye Stones and Inflammation
You mentioned being diagnosed with "eye stones" (likely referring to calcified deposits in the eye) and mild inflammation. These conditions can occur in conjunction with vitreous changes. Treatment for inflammation typically involves anti-inflammatory eye drops, which your doctor has prescribed. The presence of eye stones does not usually require surgical intervention unless they are causing significant discomfort or vision issues.

Genetic Concerns and Family History
Regarding your family history, while certain eye conditions can have a genetic component, not all visual impairments are hereditary. Your grandmother's vision issues may not directly relate to your current symptoms. However, it is always wise to discuss family history with your eye care provider, as they can help assess any potential risks based on your family's medical background.

Management and Treatment Options
Currently, there are no specific treatments to eliminate floaters, as they often become less noticeable over time. However, maintaining good eye health is essential. Here are some recommendations:
1. Regular Eye Exams: Continue to have regular check-ups with your eye care professional to monitor any changes in your vision or the presence of floaters.

2. Hydration and Eye Care: Ensure you are well-hydrated and consider using lubricating eye drops if you experience dryness, especially if you wear contact lenses.

3. Limit Eye Strain: Take regular breaks when using screens or reading to reduce eye strain, which can exacerbate discomfort.

4. Healthy Lifestyle: A balanced diet rich in antioxidants (found in fruits and vegetables) can support overall eye health.

5. Anxiety Management: If anxiety about your vision is affecting your quality of life, consider discussing this with a healthcare provider who can offer strategies or referrals for support.

In conclusion, while floaters can be concerning, they are often a normal part of the aging process and do not necessarily indicate a serious problem. However, staying vigilant about your eye health and maintaining open communication with your eye care provider is crucial. If you notice any changes in your symptoms, do not hesitate to seek further evaluation. Thank you for your questions, and I hope this information helps clarify your concerns!
