AIM To determine the clinical features of amiodarone induced optic neuropathy, which may help distinguish it from non-arteritic anterior ischaemic optic neuropathy. METHODS Retrospective observational case series of patients diagnosed with amiodarone induced optic neuropathy at the neuro-ophthalmology service from March 1998 to February 2001. Amiodarone was discontinued after discussion with ...
The authors describe a case of acute posterior multifocal placoid pigment epitheliopathy (APMPPE) with recurrent neurological complications. A 24-year-old man experienced subacute bilateral visual loss. Based on the characteristic findings in funduscopy and fluorescin angiography and after the exclusion of the differential diagnoses, APMPPE was diagnosed. During the course of the disease recurr...
DOI: 10.1590/S1679-45082015AI2979 NRS, a woman, 71-year-old, who born in São Paulo, Brazil, sought our care service complaining of progressive low visual and metamorphopsia in the right eyes (RE) for 3 months. She had no-history of comorbidities, ophthalmologic surgeries or eye diseases. Upon examination her best-corrected visual acuity was 20/80 in the RE and 20/20 in the left eye. Funduscopy ...
The role of retinal microglial cells (MCs) in age-related macular degeneration (AMD) is unclear. Here we demonstrated that all retinal MCs express CX3C chemokine receptor 1 (CX3CR1) and that homozygosity for the CX3CR1 M280 allele, which is associated with impaired cell migration, increases the risk of AMD. In humans with AMD, MCs accumulated in the subretinal space at sites of retinal degenera...
A scotopic electroretinogram with an a-wave amplitude larger than the b-wave amplitude traditionally is termed 'negative'. Six male patients with negative photopic electroretinograms were examined; three of them suffered from progressive cone dystrophy, in which negative electroretinograms are unusual. Another patient without symptoms was the brother of a patient with cone dystrophy. These pati...
Background/aims: The exact pathogenesis of glaucoma in exfoliation syndrome is unclear. There has been some suggestion that narrow angles are more common in exfoliation syndrome and that this may be a component in the disease. The degree of pigmentation has also been shown to influence the intraocular pressure. The aim was to determine whether gonioscopic features of the anterior chamber angle ...
Amadeo R. Rodriguez, MD Jason J.S. Barton, MD, PhD, FRCPC SECTION 1 A 9-year-old boy was seen for bilaterally decreased vision. The patient noted gradual decrease in his visual acuity over a few months with difficulty seeing the blackboard. Otherwise, he was asymptomatic with no headaches. His examination showed visual acuities of 20/60 in his right eye and 20/400 in his left eye. For color vis...
BACKGROUND AND PURPOSE Embolic complications during ultrasound examinations are a rare cause of neurological deficits. The present case documents the occurrence of embolism by a nonobstructive compression maneuver during transcranial Doppler examination, resulting in a minor stroke. CASE DESCRIPTION A 63-year-old man suffered from recurrent transient ischemic attacks. Duplex sonography showed...
A retired woman with left ophthalmic shingles of over 2 years' duration attended with bilateral vision loss and systemic upset. Acute retinal necrosis with detachment was detected on right fundus examination. Cataract in left eye precluded funduscopy. Ocular ultrasonography revealed fibrotic retinal detachment in the left eye. MRI brain and orbits also showed signals of retinal detachment. No a...
OBJECTIVE To determine the performance of direct funduscopy (DF) as part of the initial clinical assessment among different faculty physicians and residents from internal medicine, emergency medicine, and neurology (N). METHODS Retrospective study of 163 randomly reviewed charts of patients (>18 years) presenting either to the ED, inpatient units, or outpatient clinics from January 2001 to Ju...
