Make it simple with the W1713 suture.

We report four members of a Lebanese Druze family with the syndrome of lens dislocation, spontaneous filtering blebs, anterior segment abnormalities, and a distinctive facial appearance. The constellation of clinical abnormalities in these patients is not suggestive of the Marfan syndrome or other connective tissue disorders associated with ectopia lentis. We previously described this syndrome in another presumably unrelated and highly inbred Druze family from the mountains of Lebanon. We postulated autosomal recessive inheritance in a pseudo-dominant pedigree. A few isolated reports of similar cases are scattered in the world literature. We now confirm that this is a distinct autosomal recessive syndrome whose gene mutation is enriched in the Lebanese Druze community.

Fibrillin-rich microfibrils of the extracellular matrix: ultrastructure and assembly.

Fibrillin-rich microfibrils are a unique class of extensible connective tissue macromolecules. Their critical contribution to the establishment and maintenance of diverse extracellular matrices was underlined by the linkage of their principal structural component fibrillin to Marfan syndrome, a heritable connective tissue disorder with pleiotropic manifestations. Microscopy and preparative techniques have contributed substantially to the understanding of microfibril structure and function. The supramolecular organisation of microfibrillar assemblies in tissues has been examined by tissue sectioning and X-ray diffraction methods. Published findings are discussed and new information reported on the organisation of microfibrils in the ciliary zonular fibrils by environmental scanning electron microscopy. This review summarises microscopy and X-ray diffraction studies that are informing current understanding of the ultrastructure of fibrillin-rich microfibrils.
