• What is this yellow circle in my vision after retinal repair surgery?


    I was just treated by laser for a torn retina two days ago. Besides the floaters, I still see a perfect yellow circle when I look at a white surface. What is this and should I be alarmed?


    The yellow circle may be what we call a Weiss ring: this is a ring of tissue that normally surrounds the optic nerve but floats in the central cavity of the eye when the vitreous (gel-like substance that fills the eye) separates from the retina—which is the phenomenon that leads to the retinal tear. The ring is more obvious when looking at a white surface because the white surface provides a better contrast background.

    If this continues more than a day or worsens, I would absolutely recommend you return for a repeat evaluation with your treating ophthalmologist.
