Optic Nerve Haemangioblastoma: Signs of Chronicity

Effect 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...

P129: 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...

Spinal Nerve Root Haemangioblastoma Associated with Reactive Polycythemia

Haemangioblastomas are uncommon tumours that usually occur in the cerebellum and, less commonly, in the intramedullary spinal cord. The extramedullary spinal canal is an uncommon location for these tumours. Also haemangioblastoma at this site is not known to be associated with polycythemia. We present the clinical, imaging, and histological findings of an adult patient with extramedullary spina...

Optic nerve ischemia: optic nerve sheath decompression alone or with optic nerve decompression.

Anterior segment granuloma and optic nerve involvement as the presenting signs of systemic sarcoidosis

PURPOSE To report a case with anterior and posterior nodules associated with systemic sarcoidosis. METHODS A patient with decreased vision underwent complete ophthalmologic examination, ultrasound biomicroscopy, fluorescein and indocyanine green (ICG) angiography. RESULTS The patient presented a nodule of the iris of the OS and of the optic nerves of both eyes. Chest computed tomography and...
