AIMS To assess the effects of (1) mydriasis and (2) single versus three field photography on screening for diabetic eye disease using digital photography METHOD Slit lamp examination findings were compared to digital fundal photographs for the detection of any retinopathy and for referable retinopathy in 398 patients (794 eyes). A Topcon TRC-NW6S digital non-mydriatic fundus camera was used. ...

Autonomic signs and symptoms are a common feature of epileptic seizures. Although sympathetic activation responses are predominant, we can also find sympathetic inhibition and even an activation of the parasympathetic division of the autonomic nervous system, especially in partial seizures. These autonomic symptoms during seizures are thought to be the result of neuronal discharges arising from...

Unilateral fixed mydriasis can be an ominous sign; however in many cases, it is benign and represents pharmacologic mediated action on the iris dilator or sphincter. Differentiation between pharmacologic mediated anisocoria and physiologic anisocoria can be challenging but may save on costly imaging. An 83 year-old woman was admitted with critical limb ischemia and subsequently developed respir...

Hutchinson (1867-68) in his 'Lectures on compression of the brain' was the first to indicate that with an acutely expanding intracranial mass, the ipsilateral pupil frequently dilated and became unresponsive to light. This he attributed to compression of the third nerve. Von Bergmann (1880) and subsequently Macewen (1887) came to similar conclusions regarding the significance of paralytic mydri...

DOI: 10.1590/S1679-45082017AI4040 A 45-year-old woman sought ophthalmologic care complaining about a sudden visual acuity on her right eye and anisocoria. She denied previous comorbidities and traumas. Upon examination, her ocular motility was normal and no ptosis was seen. Slit-lamp biomicroscopy and fundoscopy exams were normal. The mydriasis of the right eye, with consensual light reflex of ...

1 Twenty-nine healthy volunteers participated in an experiment lasting for 8 weeks: Phase I (2 weeks)-pre-treatment control period; Phase II (4 weeks)-medication with either ciclazindol hydrochloride (50 mg twice daily), or desipramine hydrochloride (50 mg twice daily) or lactose placebo (twice daily) administered in a single-blind fasion; Phase II (2 weeks)-recovery. 2 Experimental sessions to...

The maintenance of mydriasis and the control of postoperative pain and inflammation are critical to the safety and success of cataract and intraocular lens replacement surgery. Appropriate mydriasis is usually achieved by topical and/or intracameral administration of anticholinergic agents, sympathomimetic agents, or both, with the most commonly used being cyclopentolate, tropicamide, and pheny...
