[Unilateral progressive annular opacity of the cornea. Apropos of a case. Clinical, histological and ultrastructural study].
A case of unilateral corneal annular opacification with a slowly progressive thickening of the cornea is reported; clinical, optical and electron microscopic studies have made possible to eliminate oedematous pathological process. The central zone of the cornea was histologically within normal aspect. In the peripheral zone intracellular mucopolysaccharides (MPS) and lipids were found in the stroma. Their presence suggest a collagen degeneration, thus likely revealing a forgotten initial stromal pathology. Its consequence, the unilateral annular thickened opacified cornea, seemed to us confusing enough to be presented and discussed.
