| olivopontocerebellar atrophy | A collection of diseases with atrophy of the cerebellum, pons, and inferior olives described in 1900 by dejerine and thomas.

Synonym: atrophoderma striatum, lineae albicantes, lineae atrophicae, linear atrophy, stretch marks, stria, striae atrophicae, striate atrophy of skin, traction atrophy, vergeture. (05 Mar 2000) |

| essential progressive atrophy of iris | Progressive atrophy of the iris without inflammatory signs, characterised by patchy loss of all layers of the iris with hole formation, migration of the pupil, degeneration of the corneal endothelium, peripheral anterior synechiae, and secondary glaucoma; usually unilateral, predominantly affecting women in their middle years. (05 Mar 2000) |

| facioscapulohumeral atrophy | A relatively benign type of muscular dystrophy commencing in childhood and slowly progressive; characterised by wasting and weakness, sometimes asymmetrical, mainly of the muscles of the face, shoulder girdle, and arms; autosomal dominant inheritance.
