A CASE is reported in which a malignant melanoma of the limbus and a cyst on the posterior surface of the iris occurred in the same sector of the eye.
REPORT OF A CASE
A woman aged 33 had always had defective vision in both eyes, and her eyes had been examined annually. The routine test in 1944 had shown no alteration from the previous year, but in 1945 her optician noticed for the first time a dark spot at 9 o'clock on the limbus of the right eye ; a month later this was found to have increased rapidly in size. No history could be obtained of injury, inflammation or a mole prior to her last refraction.
—Right Eye: With a correction of +3.75 D. cyl., axis 180 vision was 6/9. A sausage-shaped, slightly elevated melanotic tumor overlay and was concentric with the limbus from 8 to 11 o'clock.
