Blinking and shadow issues?
Hello Doctor, I am a student who has asked questions before.
Recently, my eye condition has not improved and seems to be gradually worsening, which is making me very anxious.
I would like to inquire about my situation.
Last year, I developed floaters, which have been increasing.
1.
When I blink, I can see a curved line around both eyes that resembles a blood vessel, especially when looking at white objects or walls with light; it appears as a bright line that gradually disappears after blinking.
Sometimes it appears as a dark line, and I only notice it when the light changes.
When I close my eyes and wave my hand in front of a light source, I also notice what seems like a visual field defect, but when I open my eyes and check each eye individually, it seems normal, and there is no blurriness.
I had a dilated fundus examination at the beginning of the month, which did not reveal any issues.
However, I am really troubled.
Could this be macular degeneration, glaucoma, or another issue that cannot be detected by a fundus examination?
2.
When I close one eye, I can see a patch of black blurry area, which is not very severe and can only be noticed when looking at a white wall.
It is not in the central visual field, and both eyes have it symmetrically.
There were no issues when testing with a grid chart; I only notice it when closing one eye.
When looking at things with one eye, I feel a pulling fatigue sensation at the outer corner of my eye.
I researched online and wanted to ask the doctor if I might have "central serous chorioretinopathy." I am really anxious and have visited many ophthalmology clinics, but the doctors have only performed fundus examinations without any OCT or other instruments.
I am afraid there might be issues that cannot be detected by a fundus examination.
Are there some conditions that a fundus examination cannot reveal?
3.
I would like to ask what symptoms are associated with night blindness, macular issues, or glaucoma? Are the early symptoms not very obvious?
4.
Is the central visual field referring to the area we focus on to see clearly, like when reading text? Thank you very much, Doctor, for your patience in reading this! Thank you.

Hello, anxious college student:
1.
First, it's important to know that if your retina has been examined and found to be normal, there is no need to worry about floaters.
Therefore, your concern is unfounded, and you do not need to feel anxious.
Occasional floaters are not indicative of macular degeneration or glaucoma.
2.
Central serous chorioretinopathy can be detected through examination.
3.
Symptoms will be present.
4.
We see clearly in the areas where we focus, such as when reading or writing.

Hello! Thank you for reaching out with your concerns about your eye symptoms. I understand that dealing with issues like floaters and flashes can be quite distressing, especially when they seem to be worsening. Let's address your questions one by one.
1. Visual Symptoms and Eye Conditions: The symptoms you're describing, such as seeing wavy lines or blood vessel-like patterns when looking at bright surfaces, can be related to several factors. These could include visual disturbances caused by floaters, which are common and usually benign. The fact that you had a dilated eye exam without any findings is reassuring, as it suggests that there are no immediate concerns like retinal detachment or significant retinal disease. However, if you're experiencing persistent or worsening symptoms, it might be worth discussing further testing, such as Optical Coherence Tomography (OCT), with your eye doctor. This test can provide detailed images of the retina and help identify conditions that might not be visible with a standard eye exam.
2. Concerns about Central Serous Chorioretinopathy (CSCR): You mentioned the possibility of central serous chorioretinopathy, which is a condition that can cause fluid to accumulate under the retina, leading to visual distortions. While your symptoms of a black, blurry area are concerning, they are not definitive indicators of CSCR. The symmetrical nature of your symptoms and the fact that they are more noticeable in specific lighting conditions may suggest a benign cause, such as floaters or even visual fatigue. It's important to communicate your concerns to your eye doctor, as they can evaluate your symptoms in the context of your overall eye health.
3. Symptoms of Night Blindness, Macular Issues, and Glaucoma: Night blindness typically manifests as difficulty seeing in low-light conditions, which may not be immediately noticeable until you find yourself in dim environments. Macular issues can lead to distorted vision or blind spots, particularly in the central vision. Glaucoma often presents with peripheral vision loss, which may not be apparent until the disease has progressed. Early stages of these conditions can be subtle, which is why regular eye exams are crucial for monitoring your eye health.
4. Understanding Central Vision: Central vision refers to the area of your visual field that you use for tasks requiring detailed vision, such as reading or recognizing faces. This is indeed the part of your vision that you focus on when reading text. If you are experiencing issues in this area, it is essential to discuss this with your eye care provider, as it can indicate potential problems with the macula or other central visual pathways.
In summary, while your symptoms can be concerning, many factors can contribute to visual disturbances, and not all are indicative of serious conditions. It's essential to maintain open communication with your eye care provider and advocate for further testing if you feel your concerns are not being adequately addressed. Regular check-ups and monitoring are key to ensuring your eye health remains stable. If you continue to experience anxiety about your symptoms, consider discussing this with your healthcare provider, as they can offer support and guidance tailored to your situation. Remember, you are not alone in this, and there are professionals who can help you navigate these challenges.
