Although penicillin has been extensively employed in the treatment of various syphilitic infections, only a few reports have been made evaluating its use in ocular syphilis. During the past three years we have used penicillin in the treatment of 39 patients with various manifestations of syphilis of the eye.

Good to excellent vision was finally obtained in 80 per cent of the eyes treated for the initial involvement.
