Spectrum 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...
متن کاملEffect of scuba-diving on optic nerve and sheath diameters
Background :There is not any data available about the effect of high bar pressure condition on intracranial pressure. In this study, the effect of diving on the optic nerve and sheath diameters as non-invasive markers of intracranial pressure has been investigated. Methods : Twenty professional male divers from twenty one volunteers were chosen for this cross-sectional study. Only one perso...
متن کاملMonocular nystagmus with sectoral optic nerve hypoplasia in a patient with septo-optic dysplasia.
This case depicts an unusual presentation of septo-optic dysplasia. A four-year-old female presented with monocular nystagmus and temporal optic disc pallor in her left eye. Despite a normal sized optic nerve head, magnetic resonance imaging (MRI) showed a hypoplastic intraorbital and intracranial left optic nerve in the absence of a septum pellucidum.

متن کاملP129: Use of Stem Cells to Regenerate Degenerative Optic Nerve
Stem cells are undifferentiated cells that have the ability to convert to different types of cells and after dividing, they can produce their own cells or other cells. Axons of the retinal ganglion cells, from the optic nerve. These cells lose the ability to regenerate themselves before birth. Optic nerve degeneration can result from various causes including increased intraocular pressure, comp...
متن کاملUnilateral optic nerve hypoplasia with asymmetric septum: A case report of unilateral septo-optic dysplasia
Septo-optic dysplasia is an uncommon diagnosis comprised in part of a unique composition of congenitalmalformations of the central nervous system. It is defined by three principle findings: optic nerve hypoplasia, absence of the septum pellucidum, and clinical pituitary dysfunction. The syndrome may be associated with various cerebral defects including ectopic posterior pituitary, dysgenesis of...
