Polymorphic stromal dystrophy.

Polymorphic stromal dystrophy.

Strachan (i968) described a bilateral corneal dystrophy in a 62-year-old man, characterized by punctate, irregular opacities located mainly in the deepest layers of the cornea. The middle and superficial layers were involved to a lesser extent. The size and density of the lesions were sufficient to produce a distorted view of the fundus and to break up the red reflex. Some of the larger opaciti...

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...

Stromal cell-derived factors in Duchenne muscular dystrophy

Duchenne muscular dystrophy (DMD) is characterized by increased muscle damage and an abnormal blood flow after muscle contraction leading to a state of functional ischemia. Abundant evidence suggests that endothelial circulating progenitor cells (EPCs) play an important role in mediating vascular and muscle repair mechanisms and that the stromal cell-derived factor (SDF)-1 alpha chemokine is re...

Corneal electrolysis for recurrence of corneal stromal dystrophy after keratoplasty.

AIMS To evaluate corneal electrolysis as a treatment for recurrent diffuse corneal opacities at the host-graft interface of the stroma or at the subepithelial region in two types of granular corneal dystrophy (GCD). METHODS Recurrence developed at the host-graft interface of the stroma after lamellar keratoplasty in a patient with Avellino corneal dystrophy (ACD). At surgery, the deep aspect ...
