Optical coherence tomography (OCT) is an imaging technique used to obtain three-dimensional information on the retina. In this article, we evaluated structural neuro-retinal abnormalities, especially thickness in ganglion cell complex (GCC), patients with mitochondrial myopathy, encephalopathy, lactic acidosis and stroke-like episodes (MELAS). The GCC MELAS was significantly thinner than that n...

Homonymous hemianopia is a visual field defect following stroke, tumor development, traumatic brain injury and other rare causes. Due to the damage system, lateral neglect occurs that induces difficulties with detecting objects on one side of binocular field, which exposes patients potential danger during daily activities, especially performed outside – in traffic. Different optical aids such a...

BACKGROUND AND PURPOSE Stroke following the intravenous injection of drugs may be secondary to the direct effect of the substance itself or from embolization by the inert vehicle used in the manufacturing process of the drug. CASE DESCRIPTION We describe a 39-year-old man who developed a left homonymous hemianopia after intravenous injection of a melted suppository. CONCLUSIONS Paradoxical ...

We report the case history of an adult who developed seizures with nearly pure visual symptoms due to an occipital vascular lesion. The seizures were characterized by elementary visual hallucinations in the right visual field. Interictally, a dense homonymous hemianopia was demonstrated in the clinical examination and by using perimetry, but was not recognized by the patient himself. The seizur...

Occipital lobe infarcts, hemorrhages, or metastatic tumors can present with complex visual hallucinations, sensory or proprioceptive abnormalities, speech dysfunction, visual loss, and homonymous hemianopia (HH). Treatment of occipital lobe seizures is by single or multiple antiepileptic drugs. We present a case of idiopathic occipital lobe epilepsy where the seizures were controlled by antiepi...
