Eye Symptoms: Insights on Retinal Issues and Visual Disturbances - Ophthalmology

Eye problems


Hello, doctor.
I have some questions I would like to ask.
Two months ago, I experienced flashes of light and afterimages with black spots, so I underwent a fundus examination and fundus photography.
The doctor said everything was normal.
I intended to discuss my symptoms with the doctor, but he only dismissed me with a comment about eye fatigue.
Could you please help clarify my concerns? Thank you.
1.
If there is a retinal tear or retinal detachment that goes undetected, how long can the retina sustain itself? Isn’t it typically recommended to have an examination about once a year? I am worried that if something is wrong, it might not be discovered until it’s too late.
(Please do not respond with "not necessarily," thank you.)
2.
If the visual field is impaired due to retinal detachment, could it be unnoticed if the damage occurs at the periphery?
3.
Sometimes, I see wave-like distortions at the edges of my visual field.
I am unsure what this is.
4.
When I close my eyes, I sometimes see dark patches.
5.
Occasionally, I see two parallel black lines or large square shadows in my vision.
After a while, they slowly drift in a certain direction and gradually disappear.
I am not sure what this is.
6.
When I stare at a light bulb for a while, I experience visual persistence.
However, sometimes I automatically see color patches appearing.
7.
If the visual field darkens due to retinal detachment, will I definitely notice it?
8.
Recently, I have been seeing black spots in my peripheral vision when I focus on an object.
These spots disappear when I try to look at them.
It doesn’t feel like floaters (I do have floaters that are transparent and elongated).
9.
When I rotate my eyes while focusing on an object with one eye closed, I sometimes see a circular transparent object in the center of my vision.
This persists when I keep rotating my head slowly.
I am unsure what this is.

Hello: 1.
It depends on the size and location of the tear.
2.
Yes.
3.
It is usually caused by the vitreous body.
4.
It could be a posterior image.
5.
It may be floaters.
6.
It could also be a posterior image.
7.
It should be possible; you should alternate covering each eye to observe.
8.
It is also floaters.
9.
It could be a Weiss ring, a phenomenon associated with posterior vitreous detachment.

Understanding eye symptoms, particularly those related to retinal issues and visual disturbances, can be quite complex. Based on your detailed description, it seems you are experiencing a range of visual phenomena that could be linked to various underlying conditions. Let’s address your concerns systematically.

1. Retinal Integrity and Detection of Issues: You expressed concern about the possibility of undetected retinal tears or detachments. While regular eye examinations are crucial, they are not foolproof. Retinal tears can sometimes be asymptomatic until they progress to a detachment, which is why it’s essential to be vigilant about any changes in your vision. If you experience sudden flashes of light, an increase in floaters, or a shadow over your vision, these could be signs of a serious issue that requires immediate attention. Generally, if a retinal tear is detected early, it can be treated effectively, often with laser therapy, which can prevent further complications.

2. Peripheral Vision Loss: It is indeed possible for peripheral vision loss due to retinal detachment to go unnoticed, especially if it occurs gradually. The brain often compensates for minor losses in peripheral vision, making it difficult for individuals to recognize changes until they become significant. Regular comprehensive eye exams, including visual field tests, are essential for monitoring any changes in your peripheral vision.

3. Visual Disturbances: The "water-like waves" you describe could be related to a phenomenon known as visual distortions, which can occur due to various reasons, including retinal issues or even migraines. These distortions can sometimes be benign but should be evaluated if they persist or worsen.

4. Dark Spots and Shadows: The appearance of dark spots or shadows when you close your eyes can be related to several factors, including pressure on the eyes, retinal issues, or even the normal aging process of the eye. However, if these spots are new or have changed in character, it is advisable to consult with an eye specialist.

5. Visual Afterimages: The phenomenon of seeing afterimages, such as color spots after looking at a bright light, is a normal visual response. However, if you are experiencing persistent or unusual afterimages, it may warrant further investigation to rule out any underlying retinal or neurological issues.

6. Awareness of Vision Changes: If your vision becomes darker due to retinal detachment, it is likely that you would notice it, especially if it affects your central vision. However, changes in peripheral vision may not be as easily detected, which is why regular check-ups are vital.

7. Floaters and New Visual Symptoms: The appearance of new floaters or changes in existing floaters can be concerning. While floaters are common and often benign, a sudden increase in their number or changes in their appearance should prompt an eye examination to rule out any serious conditions.

8. Transparent Shapes During Eye Movement: The transparent shapes you see when moving your eyes could be related to the vitreous gel in the eye. As we age, the vitreous can change and pull away from the retina, leading to visual phenomena that can be alarming but are often benign.

In conclusion, while many of the symptoms you describe can be related to benign conditions, it is crucial to maintain open communication with your eye care provider. If you notice any new symptoms or changes in your vision, do not hesitate to seek further evaluation. Regular eye exams are essential, especially if you have a history of retinal issues or other eye conditions. Remember, early detection and intervention are key to preserving your vision.
