Axenfeld's intrascleral nerve loop An anomalous loop of the long ciliary nerve, often accompanied by the anterior ciliary artery, which has pierced the sclera a few millimetres behind the limbus and then re-enters the sclera and supplies the ciliary body. It is usually pigmented giving rise to a 1-2 mm black dot on the sclera. It appears only in a small percentage of individuals (10-15%). Treatment is not necessary. Syn. Axenfeld's pigmented nerve loop.
Meyer's loop A bundle of inferior nerve fibres that originate from the lateral portion of the lateral geniculate body, extend forward around the anterior tip of the temporal horn of the lateral ventricle and then swing backward toward the occipital lobe. A lesion in this loop may cause a superior homonymous quadrantanopia. Syn. Archambault's loop. See optic radiations.
