Lens fringe in homocystinuria.

Lens fringe in homocystinuria.

The lens from a patient with homocystinuria was examined by scanning and transmission electron microscopy. A fringe of zonular remnants was found attached to the anterior lens capsule, and was observed to be composed of masses of short filaments in disarray, together with occasional bundles of normal-appearing zonular filaments. Although a pericapsular membrane (zonular lamella) was not observe...

Anterior dislocation of the lens in homocystinuria.

Homocystinuria is of particular interest to ophthalmologists, associated as it is with sub-luxated or dislocated lenses in over go per cent. of cases. It was first described by Carson and Neill (I962) and well over I00 cases have since been reported. The subject has recently been reviewed by Cusworth and Dent (I969) and by FranSois (1970). It is our purpose to discuss the management of anterior...

Dystonia in homocystinuria.

Three patients with homocystinuria due to cystathionine beta-synthase deficiency who developed progressive generalised dystonia are described. Although cerebrovascular thrombosis is usually thought to be responsible for neurological dysfunction in homocystinuric patients, neuropathological studies in one case and clinical and radiological evidence in the other two suggested that dystonia was no...

Pathological Findings in Homocystinuria.

Pathological findings are described in four cases of a new aminoaciduria in which homocystine is excreted in the urine. All the patients were mentally retarded children. Three of them presented diagnostic features of Marfan's syndrome. Necropsy on one case and biopsy findings in the others are described. Fatty change occurs in the liver. The most striking lesions are vascular. Metachromatic med...
