ABSTRACT
Lethargy in newborns usually indicates central nervous system dysfunction, and many conditions such as cerebrovascular events, infections, and metabolic diseases should be considered in the differential diagnosis. Nonketotic hyperglycinemia is an autosomal recessive error of glycine metabolism, characterized by myoclonic jerks, hypotonia, hiccups, apnea, and progressive lethargy that may progress to encephalopathy or even death. Cerebral sinovenous thrombosis is a rare condition with various clinical presentations such as seizures, cerebral edema, lethargy, and encephalopathy. Here, we report the case of a newborn infant who presented with progressive lethargy. An initial diagnosis of cerebral venous sinus thrombosis was followed by confirmation of the presence of nonketotic hyperglycinemia.

Neuro-ophthalmology is a subspecialty of both neurology and ophthalmology concerning visual problems that are related to the nervous system. As the rapid development of computer technology, information technology and radiology, the development of neuro-ophthalmology is in the best period in history. The following important topics are worthy of attention: 1) the diagnosis and therapy of carotid artery stenosis related ophthalmopathy;2)the relationship between papilledema and cranial venous sinus thrombosis; 3) the diagnosis of optic canal fracture with high resolution computer tomography;4)the relationship between optic neuritis and multiple sclerosis.
