An applicant showing any clinical signs of active syphilis will be assessed as temporarily unfit for a period of not less than three months from the date of the medical examination. At the end of the three months' period, provided the applicant furnishes proof, satisfactory to the medical examiner, that he has undergone adequate treatment in the interim and that the serological reaction for syphilis is negative, he may be assessed as hit but where a licence is granted or renewed in these circumstances it will be valid only for a period of three months in the first instance. Thereafter, provided serological reactions for syphilis con- tinue to be negative at the end of each three months' period, the validity of the licence will be restricted to consecutive periods of three months. When the applicant has been under observation under this scheme for a total period of at least three years and the serological reactions have continued to be negative, the restriction on the period of validity of the licence may be removed. In cases where the serological reaction for syphilis remains persistently positive, examina- tions of the cerebrospinal fluid at the end of each period of six months with negative results may be accepted in lieu of negative seralogical reactions at the end of each period of three months.
Applicants of the female sex who have a history of severe menstrual disturbances that have proven unamenable to treatment and that are likely to interfere with the safe per- formance of the duties will be assessed as unfit.
In the event of pregnancy the applicant will be assessed as temporarily unfit until, at least, after the pregnancy has been terminated. After confinement or miscarriage the applicant will not be permitted to exercise the privileges of the licence until she has undergone a medical examination and been assessed as fit. Cases of applicants of the female sex who have undergone gynaecological operations will be considered individually.
(f) Eye examination.
The functions of the eye and its adnexae shall be normal. There shall be no active pathological condition, acute or chronic, of either eye or adnexac which is likely to interfere with its proper function to an extent that would jeopardize safety in flight.
