Hi Lane,
Sudden changes in vision, especially without clear findings on scans, can be concerning. Sometimes subtle issues like macular changes, optic nerve problems, or even dry eye or systemic health factors (like blood pressure or diabetes) may not show up immediately on imaging.
It’s good that you’ve had consistent scans, but I’d recommend requesting a thorough eye exam, possibly with a retinal specialist or neuro-ophthalmologist, for a second opinion. Vision fluctuations can sometimes point to underlying issues that need closer investigation.
Wishing you clarity and answers soon.
