    retinoschisis, scleral indentation, white with pressure
    Description
    This 53-year-old man has retinoschisis involving the upper temporal quadrant but with no visible yellow dots or white lines to make it obvious. However, with scleral indentation you can see a large convex area showing the so-called white with pressure phenomenon. This area corresponds exactly to the area being indented and therefore must arise either from the outer layer of the retina or from some structure deep to it. White with pressure is an interesting optical phenomenon of uncertain origin but of no definite diagnostic or prognostic significance.
