Isolated sixth nerve palsy
An isolated sixth nerve palsy may be a harbinger of underlying intracranial disease. Due to its long subarachnoid course, it may be damaged by downward shift of the brainstem as often occurs in increased or decreased intracranial pressure (“false-localizing sixth nerve palsy”). Alternatively, the sixth nerve may be involved in isolation by a compressive lesion in the cavernous sinus or along th...
متن کاملOptic Nerve Hypoplasia
Congenital anomalies of the optic disc underlie many cases of decreased vision, strabismus, and nystagmus in childhood. A comprehensive evaluation necessitates an understanding of the ophthalmoscopic features, associated neuro-ophthalmologic findings, pathogenesis, and appropriate ancillary studies for each anomaly. The subclassification of different forms of “colobomatous” defects on the basis...
متن کاملCongenital sixth nerve palsy with associated anomalies
Congenital abduction deficit is most likely due to Duane's retraction syndrome as congenital abducens nerve palsy is very rare. We report two cases of infantile abduction deficit due to sixth nerve palsy associated with other anomalies to highlight the importance of including neuroimaging in the evaluation of an infant presenting with a limitation of abduction.
متن کاملHypoplasia of the optic nerve.
Hypoplasia of the optic nerve is uncommon (Scheie and Adler, I94I; Somerville, I962; Whinery and Blodi, I963; Ewald, I967). It is usually due to a failure of development of the ganglion cell layer of the retina and results in a small but discernible optic disc with central vessels. The disc may be cupped with a peripapillary, mottled, yellowish halo corresponding to the size of the normal disc,...
متن کاملSpectrum of optic nerve hypoplasia.
Optic nerve hypoplasia is a non-progressive condition characterised by subnormal vision and a subnormal number of optic nerve axons. It may be unilateral or bilateral, isolated or combined with other defects. Analysis of fundus photographs from a series of 7 patients with a stationary abnormality of different degrees showed that the functional defects could be closely correlated with defects in...
