In February 1959 I recorded my visual acuity with glass as 20/15+ in each eye. Soon after this, I discovered by means of a pinhole that I had a cataract (sclerosed lens) beginning in each eye. Then, my visual acuity began to fail, and by January 1963 had become very poor. However, with a dilated pupil and +3.5 OS added to my distance correction, I could read ordinary print with my right eye. At this time, I discovered that I had a large central scotoma in my left eye. On ophthalmoscopic examination, Feb 3, 1963, Dr. Paul Chandler found that the retina of this eye was covered with hemorrhages, and he made a diagnosis of obstruction of the central vein. The visual acuity of the left eye was 20/200 obtained by eccentric fixation.
The retinal hemorrhages have completely disappeared, but the central scotoma has remained. On a black target screen
