This paper presents a patient with acute, bilateral, and complete loss of vision observed during hemodialysis, proved to be central and due to ischemic infarcts in the bilateral occipital lobes. 2.
Findings suggested a central pathology, and the CT scan performed afterwards revealed large hypodense infarct areas in the bilateral occipital and parasagittal posterior region of right parietal lobes (Figures 1 and 2). Bilateral carotid artery doppler and echocardiography for differential diagnosis of thromboembolism were normal. Figure 1
Patient Data. Age: 60 years Bilateral homonymous hemianopia, cortical blindness, awareness or denial of blindness; tactile naming, achromatopia (color blindness), failure to see to-and-fro movements, inability to perceive objects not centrally located, apraxia of ocular movements, inability to count or enumerate objects, tendency to run into things that the patient sees and tries to avoid: Bilateral occipital lobe with 1999-07-01 A neurological examination was unremarkable. He did not have any cardiac murmurs and there was no carotid bruit heard.
Apart from an elevated random blood sugar level of 216 mg/dL (12 mmol/L), all other blood tests were within normal range. However, an urgent computed tomography scan of the brain showed bilateral occipital infarcts ( Figure 1 ). MR imaging of brain revealed hemorrhagic infarcts in bilateral parasagittal, parieto-occipital region and an acute infarct was seen in right cerebellum. [ncbi.nlm.nih.gov] After 12 to 24 hours, the more significant symptoms can develop, such as headache, dizziness , vertigo and blurred vision. This patient presented with bilateral inferior quadrantanopsia, which ultimately formed bilateral altitudinal defect.
The physician must be aware that a hemotoxic snakebite can even instigate ischemic dilemmas, i.e. cerebrovascular infarcts, as well.

We report magnetic resonance and digital subtraction angiography findings in the first case of bilateral occipital infarctions associated with PHA and carotid atherosclerosis. The probable mechanism underlying bilateral occipital infarcts was embolism from …
2001-10-01 He had history of bilateral occipital lobe infarcts five years ago with both eyes (OU) vision of only perception to light (PL). There was no neurological deficit apart from slurring of speech. He had no symptoms of denial of visual deficit at that time. CT brain showed multiple infarcts in both parietooccipital regions.

Bilateral Parieto-Occipital Cortex Infarcts and their Effects on the Visual Field: a Teaching Case Report | 4 | 4 and up to six months after injury.4 The most common visual field defect secondary to CVA is homonymous hemianopsia respecting the vertical meridian. Other defects include homonymous quadrantanopsia or altitudinal defects.

There were 4 patients with bilateral thalamic infarcts and 5 with bilateral occipital infarcts. In 11 patients the occipital infarct was associated with another infarct at a different level, and 6 patients each had a cerebellar infarct together with a brain-stem infarct. In 12 patients the lesions were localized to three or more areas.

Our patient had one such complication-bilateral cortical blindness resulting from bilateral occipital ischemic infarcts. The physician must be aware that a hemotoxic snakebite can even instigate ischemic dilemmas, i.e. cerebrovascular infarcts, as well. A 28-year-old man developed cerebral blindness from infarction of both mesial occipital lobes after cardiogenic hypotension induced by electrical shock.
