A 1987study of 74 boxers found at least one ocular injury in 66% of the enrolled boxers. Vision-threatening injuries, defined as significant damage to the angle, lens, macula, or peripheral retina, occurred in 58% of boxers. Nineteen percent of boxers had angle abnormalities. Nineteen percent of boxers had pathologic cataracts, and over 70% of these were posterior subcapsular. Six boxers had macular lesions and a total of 24% of boxers had retinal tears.
