A blind but grossly normal eye was removed because of severe pain. With the patient's consent, photo‐coagulation markers were placed along the horizontal meridian of the retina prior to surgery. The angular coordinates in visual space of the markers were determined by an ophthalmoscopic procedure. The loci of the markers were also determined in a flat preparation following enucleation. The relationship between retinal arc and perimetric eccentricity was found to be approximately linear up to at least 50 degrees. Our findings validate earlier theoretical calculations within this range.
