1/5. Accidental mydriasis from exposure to Angel's trumpet (datura suaveolens).

    PURPOSE: To report clinical findings after accidental instillation into the eye of sap from Angel's trumpet (datura suaveolens). methods: We report findings on seven patients who developed sudden onset of unilateral mydriasis. At least three of them also had ipsilateral cycloplegia and one developed transient tachycardia. RESULTS: The symptoms evolved after ocular exposure to sap from Angel's trumpet, a plant containing natural alkaloids with parasympatholytic properties. Six patients were initially unaware of the cause of their symptoms. In these cases, patient history revealed recent contact with Angel's trumpet. CONCLUSION: Accidental ocular instillation of sap from Angel's trumpet should be noted as a cause of sudden onset of mydriasis in otherwise unaffected patients and also of general symptoms like tachycardia.

2/5. Unilateral hyperhydrosis in Pourfour du Petit syndrome.

    Upper limp hyperhydrosis is an idiopathic disease with bilateral involvement. However, Pourfour du Petit syndrome, the opposite of horner syndrome, may result in unilateral upper limb hyperhydrosis. It occurs following hyperactivity of the sympathetic cervical chain as a consequence of irritation secondary to trauma. We report herein two cases with Pourfour du Petit syndrome showing unilateral upper limb hyperhydrosis. The patients presented with right-sided mydriasis and ipsilateral hemifacial hyperhydrosis. The onset of disease was followed by a trauma in both patients. They underwent upper thoracic sympathectomy with favorable outcome. A history of an antecedent trauma in patients with unilateral upper limb hyperhydrosis and anisocoria may imply a possible diagnosis of Pourfour du Petit syndrome.

3/5. Inferior oblique paresis, mydriasis, and accommodative palsy as temporary complications of sinus surgery.

    A 15-year-old boy had temporary hypertropia, supraduction deficit, ipsilateral mydriasis, and accommodative paresis after bilateral endoscopic ethmoidectomy, bilateral partial inferior turbinectomy, septoplasty, and Caldwell-Luc procedures for chronic sinusitis. Postoperative imaging did not disclose any intra-orbital abnormalities. The patient was treated with oral prednisolone 70 mg/day on a tapering schedule. Within two months, the ophthalmic abnormalities had resolved. This is the second report to describe such findings, which are attributed to damage of the inferior division of the third cranial nerve secondary to manipulation of adjacent ethmoid tissues.

4/5. Oculosympathetic hyperactivity in idiopathic hyperhidrosis.

    We describe a patient suffering from idiopathic hyperhidrosis, more pronounced on the right side, who presented with intermittent oculosympathetic hyperactivity (mydriasis, lid retraction and more rapid pupillary dilatation) on the same side. mydriasis was induced by stress, loss of sleep and cold pressor test. The clinical features in this patient suggest an involvement of the hypothalamic structures.

5/5. Penetrating eye injury from a rigid infant pacifier.

    BACKGROUND: The use of infant pacifiers (dummies) is common in Australasian communities and has been reported to be associated with various injuries, but to date ocular trauma has not been reported. CASE REPORT: A 14-month-old child sustained a penetrating eye injury from the infant pacifier that was in his mouth during a minor fall. Only a lid laceration was detected at the time. One week later he presented with mydriasis, heterochromia and a poor red reflex. diagnosis of a penetrating eye injury was made by examination under anaesthesia, with B-scan ultrasonography demonstrating hypotony but no retinal detachment or intraocular foreign body. Funduscopy revealed a small inferior vitreous haemorrhage. Exploration of the globe adjacent to the lid wound showed a 6 mm laceration through the sclera plugged with prolapsed vitreous. CONCLUSION: Serious ocular injury may result after a minor fall with some designs of rigid infant pacifiers. Heterochromia and anisocoria noted by the mother heralded more serious ocular injury in this case. The delay in diagnosis of this injury emphasizes the importance of ocular examination to exclude eye trauma when injuries occur around the orbit.
