Visual Disturbances: What Do Those Strange Lines Mean?

Seeing tear-like lines in the vision?

Hello, doctor.
I apologize for bothering you, but I have been troubled by this issue for a long time and cannot concentrate on my studies, so I would like to ask you.
For the past six months, I have been experiencing floaters in my eyes and consulted a doctor, who said I do not have floaters syndrome, so I didn't think much of it.
Recently, when I see bright lights and then look away, I notice a quick black shadow passing by.
When I calm down and blink rapidly, I can see tear-like lines.
Additionally, when I roll my eyes upward, I see two black circles, and lately, when I look left or right, I also see black things flashing quickly.

My questions are:
1.
How is retinal detachment tested? Am I experiencing retinal detachment?
2.
Do I need to see a doctor for this?
3.
Why do I see shadows following bright lights?
4.
What does it mean when I see tear-like lines while blinking rapidly? This feels very serious.

5.
Why have I been seeing two black circles when I look upward (similar to rolling my eyes)? This symptom has been present for a long time.

6.
When I press my eyes with my hands, I see dots like an old television malfunctioning slowly moving toward the center, and if I press longer, I can't see anything at all, but it gradually goes away afterward.

Please, doctor, help me with these questions.
I am really worried about my eyes.

You do not have a retinal detachment.
In cases of retinal detachment, vision is typically lost.
I recommend that if you have any concerns, you should undergo a dilated eye examination.
If the dilated exam shows no issues, there is no need to worry too much.
As for the abnormal images you are seeing, it is difficult to determine the cause, and I cannot provide an answer.

Hello! Thank you for reaching out with your concerns about your vision. It’s understandable to feel anxious when experiencing unusual visual disturbances, especially when they interfere with your daily activities like studying. Let’s address your questions one by one.

1. Testing for Retinal Detachment: Retinal detachment is a serious condition that can lead to permanent vision loss if not treated promptly. Symptoms may include sudden flashes of light, floaters, or a shadow or curtain over your vision. To test for retinal detachment, an eye doctor will perform a comprehensive eye exam, which may include dilating your pupils to get a better view of the retina. They may also use imaging techniques like optical coherence tomography (OCT) or ultrasound if necessary. If you are experiencing symptoms like flashes of light or a sudden increase in floaters, it’s crucial to see an eye doctor as soon as possible.

2. Do You Need to See a Doctor?: Yes, based on your description of seeing black shadows, rapid flashes, and the tearing lines, it is advisable to consult an eye care professional. These symptoms could indicate various issues, including retinal problems or other ocular conditions that require immediate attention. It’s better to err on the side of caution when it comes to eye health.

3. Seeing Shadows After Looking at Bright Lights: When you look at a bright light and then turn away, the afterimage effect can cause temporary visual disturbances. This is due to the photoreceptors in your retina becoming overstimulated. However, if these shadows persist or are accompanied by other symptoms, it could indicate a more serious issue, such as retinal damage or a migraine aura.

4. Seeing Tearing Lines When Blinking Rapidly: The tearing or wavy lines you see when blinking rapidly could be related to the way your brain processes visual information. This phenomenon might be associated with visual fatigue or strain, especially if you have been focusing on something for an extended period. However, if this symptom is new or worsening, it’s essential to discuss it with your eye doctor.

5. Black Circles When Looking Up: The appearance of black circles when you look up could be related to several factors, including the presence of floaters, which are small clumps of gel or cells inside the vitreous (the gel-like substance in your eye). They can cast shadows on your retina, leading to the perception of dark spots or circles. If this has been a persistent issue, it’s worth mentioning to your eye care provider.

6. Visual Disturbances When Pressing on Your Eyes: Pressing on your eyes can cause temporary visual effects, such as seeing spots or patterns. This is due to the pressure stimulating the retina and the optic nerve. However, this is not a recommended practice, as it can potentially cause damage to your eyes. If you notice significant changes in your vision after applying pressure, it’s important to avoid doing so and consult an eye doctor.

In summary, your symptoms warrant a thorough examination by an eye care professional. It’s essential to communicate all your experiences, including the visual disturbances and any changes in your vision. Early detection and intervention are key to maintaining eye health and preventing potential complications. Please don’t hesitate to seek medical attention; your vision is important, and it’s always best to be proactive about your eye health.
