67. If the victim suffers a relapse of his injury within two years after the end of the last period of incapacity for which he was entitled to an income replacement indemnity or, if he was not entitled to such an indemnity, within two years after the date of the manifestation of the injury, he shall receive compensation from the date of the relapse as though his incapacity had not been interrupted.
If, however, the indemnity computed on the basis of the gross income actually earned by the victim at the time of the relapse is greater than the indemnity to which the victim would be entitled under the first paragraph, the victim shall receive the greater of the two.
If the victim suffers a relapse more than two years after the time indicated in the first paragraph, he shall receive compensation as if the relapse were another injury.
