Wavy Vision: Should You See a Doctor for This Eye Symptom? - Ophthalmology

Visual disturbances appear wavy?


Hello, doctor.
When I look at things, especially small tiles, I sometimes see a wavy pattern that moves but does not distort.
This occurs more frequently at night than during the day.
I have undergone a grid test, and the central vision does not deform, but I occasionally perceive a wavy pattern in my peripheral vision.
This happens intermittently.
My prescription is -3.00 and -2.75, and I have a history of floaters and astigmatism.
I would like to know if I need to see a doctor for these symptoms.

Hello Cwz: Based on your description, it is possible that you are experiencing vitreous degeneration.
It should not be a major concern, but it is still advisable to get it checked for peace of mind.
In Taiwan, the ophthalmology department at Puzi Hospital is open on Monday, Tuesday, Thursday, and Friday mornings from 8:00 AM to 12:00 PM, and Wednesday afternoons from 2:00 PM to 4:30 PM.
Please note that online responses are for reference only; if necessary, you should seek medical attention at a healthcare facility.
I hope to have the opportunity to assist you.
Best regards, Gao Pilin.

Wavy vision, especially when it occurs intermittently and is more pronounced at night, can be concerning and warrants a thorough evaluation by an eye care professional. Given your description of seeing wavy patterns, particularly with small tiles, and the presence of floaters and astigmatism, it is essential to consider several factors that could be contributing to your symptoms.

Firstly, the phenomenon of wavy vision could be related to a few different ocular conditions. One possibility is that it may be associated with visual disturbances caused by your existing conditions, such as astigmatism or floaters. Astigmatism can cause light to be focused unevenly on the retina, leading to distorted or wavy images. Floaters, which are small specks or clouds that drift through your field of vision, can also create visual disturbances, particularly if they are more pronounced in certain lighting conditions or when looking at plain backgrounds.

Another potential cause of wavy vision is related to the health of the retina. Conditions such as retinal tears or detachments can lead to visual distortions, including wavy or wiggly lines. While you mentioned that your central vision appears normal based on the Amsler grid test, it is still crucial to rule out any underlying retinal issues, especially since you have a history of high myopia (nearsightedness), which increases the risk of retinal complications.

Additionally, the fact that your symptoms are more noticeable at night could suggest that your eyes are experiencing fatigue or strain, particularly if you are using screens or engaging in activities that require prolonged focus. Nighttime vision can be affected by various factors, including reduced light levels, which can exacerbate visual disturbances.

Given these considerations, it is advisable to consult with an eye care professional, preferably an ophthalmologist, who can perform a comprehensive eye examination. This examination should include a detailed assessment of your visual acuity, a thorough evaluation of your retina, and possibly imaging studies such as optical coherence tomography (OCT) to visualize the layers of the retina and check for any abnormalities.

When you visit the doctor, be prepared to describe your symptoms in detail. Mention when the wavy vision occurs, how long it lasts, and any other accompanying symptoms, such as headaches or eye strain. This information will help the doctor make a more accurate diagnosis.

In summary, while wavy vision can sometimes be benign, especially in the context of existing conditions like astigmatism and floaters, it is essential to have it evaluated by a professional to rule out any serious underlying issues. Early detection and intervention can be crucial in maintaining your eye health, especially given your history of high myopia. Therefore, I recommend scheduling an appointment with an ophthalmologist as soon as possible to address your concerns and ensure your eyes are healthy.
