[Syphilitic parenchymatous keratitis].

It shows a clinical observation about luetic bilateral keratitis at a young man 17 years old. The high-positive VDRL, the presence of the AT antigen, the bilateral low hearing perception and the left low hearing transmission associated with minimal dental malformations suggest the luetic congenital etiology of the disease. The AT positive-test at the patient's mother (which VDRL is negative) shows a tardive luetic infection during the pregnancy, that has determined the apparition at the fetus of congenital lately lues. The specific antiluetic treatment with Benzylpenicillinum kalicum and Prednisonums the evolution of the disease is spectacularly good. Six weeks after the beginning of the treatment V.A. is 1 at the both eyes and the neoformation vessels are completely obturated. The paper insists on the medical and social implications of the ignored complications of late lues.
