Schnyder’s crystalline corneal dystrophy

Central crystalline corneal dystrophy.

The purpose of this paper is to report the first family from Great Britain with central crystalline corneal dystrophy and to discuss the pathogenesis of this condition, a welldocumented entity (Waardenburg, Franceschetti, and Klein, I96I), the genetical basis of which was first demonstrated in a family of eight by van Went and Wibaut (1924), and confirmed by Schnyder (1927, I929, 1939). The con...

Crystalline Subtype of Pre-Descemetic Corneal Dystrophy

PURPOSE To report corneal findings in a familial case of the crystalline subtype of pre-Descemetic corneal dystrophy. CASE REPORT A 19-year-old girl and her 44-year-old mother were found to have asymptomatic, bilateral, punctiform and multi-colored crystalline opacities across the whole posterior layer of the corneas. Endothelial specular microscopy revealed the presence of white round flecks...

Bietti's tapetoretinal degeneration with marginal corneal dystrophy crystalline retinopathy.

In 1937 Bietti reported a tapetoretinal degeneration with associated corneal deposits at the limbus. The hallmark of the disease was the crystalline characteristics of the retinal spots as well as those at the corneal limbus. Bagolini and Ioli-Spade in 1968 presented a 30 year follow-up on Bietti's cases and presented six additional cases. The present report delas with this entity in Orientals,...

Specular microscopic findings of corneal deposits in patients with Bietti's crystalline corneal retinal dystrophy.

Crystalline stromal dystrophy: histochemistry

A report of a woman in her fifties with Schnyder's crystalline stromal dystrophy is presented. There is no personal or family history of hypercholesterolaemia. A full thickness corneal disc was removed before grafting and examined by polarised light, histochemistry, and electron microscopy. Specific lipid histochemical methods showed deposits of cholesterol and cholesterol ester in the superfic...
