Visual Perseveration (Afterimages and Trails)
Type: Persistent aura symptom — may last weeks, months, or years. Often bilateral (affecting both sides of vision or both ears). Rare but well-documented.
What is it?
Visual perseveration is a persistent problem where images linger, repeat, or follow your eyes and movement. Instead of images disappearing instantly when you look away, they remain in your vision for several seconds or longer. This includes afterimages, trails behind moving objects, and palinopsia (images reappearing unexpectedly).
What it feels like
When you look at something and then shift your gaze or close your eyes, the image stays visible. It may reappear in the same location or fade slowly. Moving objects leave trails or smears behind them as they move. These afterimages and trails can be dark (negative afterimages) or the same color as the original object (positive afterimages). The persistence of images makes reading, watching screens, or driving difficult because you cannot see clearly without the lingering afterimages cluttering your vision. It feels as if your visual system is unable to clear images efficiently.

How patients describe it
“I look at something, turn my head and then see it again. Or I am looking at something, move it and still see it where I moved it from (the longest an image has remained in my sight is 8 seconds). I am having biggest problems watching tele and driving.” — S.
“Usually my symptoms are limited to scintillating scotoma that ‘forced reminiscence/dreamlike’ state, sometimes followed by headache, but the past couple of days, I’ve had lower jaw/lip/ right hand fingers numbness occur briefly.” — M.C.
“I thought I did not get aura with my migraines; no seeing stars or sparkly, flashy patterns. But I do - sometimes - get tunnel vision and after that the world seems glossy, stylized, black&white.” — A.D.
Subtypes
Negative Afterimages
Dark afterimages that appear after looking at bright objects. Reported by 15 of 60 subjects. You see a dark shadow or silhouette of what you just looked at, particularly after viewing bright light.
Positive Afterimages
Afterimages that retain the color and brightness of the original object. Reported by 6 of 60 subjects. The image looks like a copy of the original, not inverted or darkened.
Trails
Moving objects appear to leave a smear, blur, or trail behind them. Reported by 7 of 60 subjects. This makes watching movement, driving, and reading text difficult because motion is not perceived as clean or fluid.
Palinopsia
A previously seen image reappears in the visual field unexpectedly. Reported by 2 of 60 subjects. Images that you are not currently looking at suddenly reappear visually without explanation.
What makes it worse
Visual perseveration often worsens when looking at bright objects, high-contrast images, or moving stimuli. Screens, busy visual environments, and rapid eye movements can intensify the problem. Fatigue, stress, and lack of sleep may exacerbate the symptom. Some patients report worsening during or after migraine attacks or during menstrual cycles.
What may help
Dark glasses, tinted lenses, or blue light filters can reduce the intensity of afterimages. Some patients benefit from visual rest and limiting exposure to bright or high-contrast environments. Stress reduction, adequate sleep, and hydration may help. Cognitive behavioural therapy and distraction techniques can help patients manage the visual disturbance. Mindfulness and acceptance strategies may reduce the emotional distress associated with the symptom.

Clinical note
Visual perseveration is reported by 18 of 60 subjects with definite persistent aura. Evaluation by a neuro-ophthalmologist or neurologist is important to rule out other causes of visual disturbances. A normal brain MRI helps confirm the diagnosis of persistent aura without infarction. This symptom can be distressing but is not associated with progressive visual damage.
If this is the first time you experience these symptoms, or they feel different from previous episodes, seek medical evaluation to rule out other causes.
