Seeing Strange Patterns in Vision: Possible Retinal Issues Explained

Seeing strange stripes or patterns when looking at objects?

Hello Doctor: In the past few nights, I have been seeing strange patterns with yellow backgrounds and black stripes (similar to the net-like pattern of a cantaloupe) in my vision, lasting for more than 10 minutes.
Even when I close my eyes, I can still see this glowing, flickering object.
Could this be a sign of retinal detachment? I am concerned because some large hospitals have very specialized ophthalmology departments, and I am worried about wasting time by seeing the wrong doctor.
I have a history of dry eye syndrome, but it has improved with the change of seasons.
Additionally, I often notice blood vessels in my eyes; the last time I visited a clinic, the doctor mentioned that there were quite a few blood vessels.

Seeing strange patterns in your vision, such as yellow backgrounds with black stripes resembling a cantaloupe net, can be concerning and warrants a thorough examination. Based on your description, these visual disturbances could be related to several potential retinal issues, but they do not necessarily indicate retinal detachment.

Retinal detachment is a serious condition where the retina separates from the underlying supportive tissue. Symptoms typically include sudden flashes of light, floaters, or a shadow or curtain effect over your vision. The fact that you are experiencing these patterns for a duration of 10 minutes or more and that they persist even when your eyes are closed suggests that they may be related to visual phenomena rather than a direct retinal detachment.

One possible explanation for the visual patterns you are experiencing could be related to a condition known as "visual migraine" or "migraine aura." This condition can cause temporary visual disturbances, including zigzag patterns, flashes of light, or other unusual visual experiences. These symptoms can last from a few minutes to about half an hour and are often not accompanied by a headache. If you have a history of migraines, this could be a plausible explanation.

Another possibility is that you are experiencing a form of visual snow or entoptic phenomena, where you perceive visual disturbances that are not present in the external environment. This can be exacerbated by factors such as fatigue, stress, or changes in lighting conditions. Given your history of dry eyes and the presence of blood vessels in your eyes, it is also possible that ocular surface issues could contribute to visual disturbances, particularly if your eyes are not adequately lubricated.

Since you mentioned that you have previously experienced dry eye syndrome, it is essential to ensure that your eyes are well-hydrated, as dryness can lead to visual disturbances. Additionally, the presence of blood vessels in your eyes could indicate chronic irritation or inflammation, which may also contribute to visual symptoms.

Given the complexity of your symptoms and the potential for various underlying causes, it is crucial to seek a comprehensive evaluation from an ophthalmologist. When you visit the eye clinic, make sure to communicate all your symptoms clearly, including the duration, frequency, and any accompanying factors (like stress or fatigue). This information will help the doctor determine the appropriate tests and examinations needed to assess your retinal health accurately.

In terms of the specific concern about retinal detachment, it is advisable to undergo a dilated eye exam, which allows the doctor to visualize the retina thoroughly. This examination can help rule out any serious conditions, including retinal tears or detachments. If necessary, additional imaging tests such as Optical Coherence Tomography (OCT) can provide detailed images of the retina and help identify any abnormalities.

In conclusion, while your symptoms are concerning, they do not definitively indicate retinal detachment. However, it is essential to seek professional medical advice to rule out any serious conditions and to address your visual disturbances appropriately. Regular eye examinations and open communication with your eye care provider are key to maintaining your ocular health and addressing any emerging issues.
