This disease is characterized by a sialidase deficiency and a severe glomerular nephropathy. The ocular pathology provides the principal features of the disease showing both mucopolysaccharidic and glycolipidic storage.

A description of a non-excretory myeloma located in the orbit. The authors stress the importance of immunofluorescent and ultra-structural studies in the identification of these tumours. They discuss the relationship between multiple myeloma and extra-medullary plasmocytoma and raise the possibility of modes of transmission.
Ultrastructural study of two cases of persistent hyperplastic primary vitreous. Behind posterior lens capsule we find a connective tissue where fibroblasts present an intense activity. Numerous vessels and neuro-ectodermal tissue were noted.
Two cases of persistent hyperplastic primary vitreous have been managed by the vitreous cutter Sukon "Alternating" with a pars-plana approach.
Study of six cases of vitreous touch syndrom with histopathology of five buttoms of kératoplasty. Light and electron-microscopy demonstrate many alterations of Descemet's membrane, which is thickened, devided in sheets. In one specimen there was a retrocorneal fibrous membrane and "fibroblast like cells". These findings support the mechanism of endothelial fibrous metaplasia as the origin of the retrocorneal fibrous membrane during vitreous touch syndrom.
