WebAn acquired oculomotor nerve palsy (OMP) results from damage to the third cranial nerve. It can present in different ways causing somatic extraocular muscle dysfunction (superior, inferior, and medial recti; inferior oblique; and levator palpebrae superioris) and autonomic (pupillary sphincter and ciliary) muscles. WebHomatropine (hydrobromide) is normally used to produce mydriasis (pupil dilatation) and cycloplegia (paralysis of the ciliary muscle) in order to allow examination of the eye, measurement of refractive errors, and relief from acute uveitis (inflammation of the iris, ciliary body or choroids).
