RATIONALE: Functional visual loss (FVL) can manifest as various symptoms. Decreased distant visual acuity is the most common symptom and visual field defect is the second most common symptom. Hemianopsia is rarely reported. In an atypical situation of FVL, it is important to prove that no organic pathology exists, through detailed history taking and appropriate examinations. PATIENT CONCERNS: This review presents the case of a 48-year-old male patient presented with decreased bilateral visual acuity and visual field defect after a traffic accident 3 weeks ago...

AIM: To establish the possibility of retrograde trans-synaptic neural degeneration following acquired post-geniculate visual pathway damage. MATERIAL AND METHODS: Twenty-two patients with homonymous hemianopia caused by acquired post-geniculate visual pathway damage were examined. Peripapillary retinal nerve fiber layer (RNFL) thickness and ganglion cell complex (GCC) measurements were assessed with RTVue-100 Fourier-domain optical coherence tomography (OCT). RESULTS: In 12 out of 22 patients we detected binocular GCC thinning that was ipsilateral to post-geniculate involvement...

BACKGROUND: Laser interstitial thermal therapy (LITT) is quickly emerging as an effective surgical therapy for temporal lobe epilepsy (TLE). One of the most frequent complications of the procedure is postoperative visual field cuts, but the physiopathology of these deficits is unknown. OBJECTIVE: To evaluate potential causes of visual deficits after LITT for TLE in an attempt to minimize this complication. METHODS: This retrospective chart review compares the case of a 24-year-old male who developed homonymous hemianopsia following LITT for TLE to 17 prior patients who underwent the procedure and suffered no visual deficit...

Acute arterial tumor embolism is a rare complication in cancer patients. Most of the previously reported cases of arterial tumor embolism have been associated with pulmonary malignancies and occurred during the intraoperative and postoperative periods. Very few cases occurred spontaneously. To our knowledge, there is no previous report of spontaneous and massive tumor embolism occluding the abdominal aorta in patients suffering from primary pulmonary carcinoma. We describe the case of 64-year-old man who presented with left homonymous hemianopsia and backache...

A 63-year-old woman presented to her ophthalmologist complaining of reading difficulties for two years. Ophthalmological examination revealed a homonymous hemianopsia. Brain magnetic resonance imaging (MRI) scan was interpreted as normal, but positron emission tomography (PET) showed areas of posterior brain hypometabolism. This case highlights the high diagnostic suspicion that ophthalmologists should have regarding posterior cortical atrophy (including the visual variant of Alzheimer disease) in patients complaining of reading difficulties in the setting of a normal ophthalmic examination...

PurposeTo describe the neuro-ophthalmologic findings of cholangiocarcinoma.MethodsWe report a retrospective chart review of cholangiocarcinoma patients presenting at two tertiary care centers in the Texas Medical Center.ResultsFive patients with neuro-ophthalmologic symptoms related to cholangiocarcinoma were identified. One patient presented with diplopia due to metastasis to the left medial rectus muscle, two patients had metastasis to the occipital lobe resulting in homonymous hemianopsia, one patient had involvement of the clivus resulting in sixth nerve palsy, and one presented with a hypercoagulable state-related stroke causing a homonymous hemianopsia and visual hallucinations...

A middle-aged man with a history of type 2 diabetes mellitus, hypertension, hyperlipidemia, prior cerebral vascular accident, and remote history of generalized seizure disorder presented with worsening right-sided visual deficits and focal seizures. On examination the patient had dense homonymous hemianopsia on the right side. He was initially diagnosed with a stroke and underwent further investigation for potential causes. However, upon further review, magnetic resonance imaging (MRI) findings and repeat examination were more consistent with seizure-related effects on cortical brain matter as the cause of his visual disturbances rather than stroke...

Fibromuscular dysplasia (FMD) is a nonatherosclerotic, noninflammatory arterial disease that most commonly affects the renal and internal carotid arteries, but intracranial FMD is very rare. We report a patient with FMD involving the posterior cerebral arteries (PCAs). A 24year old female was presented with a 4day history of right homonymous hemianopsia with throbbing headache in the left temporo-occipital area. The brain magnetic resonance imaging (MRI) revealed an acute ischemic stroke in the left PCA territory, while the Time of Flight (TOF) magnetic resonance angiogram (MRA) showed segmental luminal irregularities in the left proximal PCA...

BACKGROUND: Posterior reversible encephalopathy syndrome (PRES) is characterized by headache, altered mental status, visual changes, and seizure combined with brain imaging consistent with cerebral edema without infarction. To the best of our knowledge, we report the first case of PRES after an endoscopic endonasal resection of a pituitary macroadenoma. CASE DESCRIPTION: A 59-year-old woman was diagnosed with a pituitary macroadenoma, for which she underwent endoscopic endonasal extracapsular resection...

Creutzfeldt-Jakob disease (CJD) is a rare neurodegenerative disorder characterized by rapidly progressing dementia, general neurologic deterioration, and death. When the leading symptoms are visual disturbances, it is termed as the Heidenhain variant of CJD (HvCJD). CJD was reported following prion-contaminated pericardium transplants but never after bovine bioprosthetic cardiac valve. In this case report, we describe HvCJD in a patient who had a bovine bioprosthetic cardiac valve implant. An 82-year-old-woman was referred to neuro-ophthalmology clinic for unexplained visual loss that started 1 month previously...

Homonymous hemianopsia (HH) is a common adverse outcome after stroke. Spontaneous improvement more than 6 months poststroke is thought to be unlikely, and traditional visual rehabilitation techniques lack clear evidence of efficacy. The case presented is of a 22-year-old woman who demonstrated improved compensation of her stroke-induced HH after the initiation of a selective serotonin reuptake inhibitor (SSRI). There is evidence supporting the use of SSRIs to improve poststroke cognitive impairment, motor impairment, and depression...

A 19-year-old woman had a thunderclap headache, followed by left hemiparesis and left homonymous hemianopsia. Laboratory tests showed no signs of infection and immunological test results were unremarkable. MRI revealed a cerebral infarction in the right posterior cerebral artery territory, and digital subtraction angiography(DSA)showed right posterior cerebral artery stenosis on day 2. The first follow-up DSA demonstrated an irregular, bead-like appearance on day 9, but the stenotic lesion returned to normal on day 21...

We report a case of a 55-year-old man who developed acute-onset narrowing of his visual field. He showed right homonymous hemianopsia without any other neurological symptoms and signs. Brain CT and MRI showed localized hemorrhage (about 1.6 ml) in the left lateral geniculate body (LGB). A cerebral angiography showed no vascular anomalies of cerebral vessels, and the left anterior choroidal artery and left lateral posterior choroidal artery could be visualized well. He had hypertension, polycythemia and dyslipidemia and was a habitual smoker and an alcoholic...

Clinical and radiological features or characteristics of posterior clinoid process (PCP) meningiomas have rarely been described because of their extreme scarcity and terminological confusion. Therefore, the strategies in the surgical intervention for PCP meningiomas have not been well established. Moreover, the presence of deep and critical neuroanatomical structures and relatively high morbidity, which can be difficult to predict preoperatively, make their surgical excision more challenging. We report two surgical cases of PCP meningioma and discuss the appropriate assessment of preoperative features and surgical strategies with review of the literature...

About 20%-30% of patients undergoing neurological rehabilitation report visual field defects, one of the most frequent of which is homonymous hemianopsia (loss of the same half of the visual field in both eyes). There is still no consensus as to whether homonymous hemianopsia is best treated in a restorative or compensatory manner. The aim of this review is to describe the effects of restorative rehabilitation, whose long-term efficacy is still being debated. We analyzed 56 articles describing the use of various techniques used to promote visual field recovery but concentrating on two approaches: "border training," which involves exercising vision at the edge of the damaged visual field, and "blindsight training," which is based on exercising unconscious perceptual functions in the mild of the blind hemifield where the scotoma is deep...

This case report describes the detection of homonymous hemianopsia and delirium during the admission physical examination of a patient with esophageal adenocarcinoma, resulting in the new diagnosis of subacute hemorrhagic stroke. The poststroke visual field defect can result in significant disability and reduction in quality of life. Patients with visual field cut show a severely reduced quality of life and require additional neuropsychological and visual rehabilitation. Only thorough physical examination is able to challenge prior negative positron emission tomography scan, leading to the diagnosis of subacute stroke and, following appropriate treatment, secondary stroke prophylaxis and rehabilitation, instead of brain radiation and chemotherapy...
