Though the human eye generally creates a single image on the retina, the literature contains many examples showing perceptual monocular diplopia. Previously, monocular diplopia resulting from astigmatic defocus has been demonstrated to cause a notch (local minimum) in the contrast sensitivity function (CSF). We examine Verhoeff's (1900) model which explains how monocular diplopia can occur thro...

Although ophthalmoplegia following snake bites is not indicative of a serious neurotoxic complication, symptoms of diplopia, dizziness and ocular discomfort can be emotionally devastating for patients. The authors experienced two cases of ophthalmoplegia following snake bites in Korea. The patients complained of diplopia that had developed several hours after the snake bites. The diplopia did n...

We present a case report of bupropion-induced diplopia in a 26-year-old woman who suffered from atypical depression. After four weeks of taking bupropion (225 mg per day) she complained of headaches, blurred vision, and diplopia. No neurological and ophthalmologic abnormal signs were found. Her brain magnetic resonance imaging (MRI) and magnetic resonance venography (MRV) were normal as well. A...

PURPOSE To evaluate the predictive factors for development of diplopia and extraocular muscle movement (EOM) limitations in the patients with isolated pure blow-out fracture. METHODS One hundred thirty-two patients with isolated pure blow-out fracture were included. The diagnosis was done with computed tomography scan. Possible predictive factors were analyzed with logistic regression. The ca...

Background: Microvascular ocular cranial nerve palsy can result from diabetes and hypertension and may be increasing with the increase in the incidence of diabetes and hypertension in Nigeria. Objective: This study provides clinical considerations for the neuro-ophthalmic evaluation of diplopic patients with presumed microvascular ocular cranial nerve palsy. Method: A case report is presented o...

BACKGROUND Diplopia is a symptom with very different etiologies. It may be caused by pathology in the eye, orbit, extraocular muscles, neuromuscular junction, or in the central nervous system. CASE REPORT Three clinical cases of hospitalization due to isolated diplopia are presented here, illustrating different etiologies. CONCLUSIONS The present article aims to address the differential dia...
