Optic neuritis an inflammatory disorder of the optic nerve inflammation is usually in young’s with symptoms of eye pain and vision loss that occurs is a common symptom of MS. Optic neuritis is one of the first symptoms of MS that observable into disorders in white matter of cerebral cortex. The risk of MS in patients with optic neuritis during 2 years 20% in 15 years, 45-80% is calculated...

THE diagnosis of progressive unilateral visual failure, when occurring as a solitary symptom in association with a visual field defect and when all routine investigations are negative, presents many difficulties. Amongst the conditions to be considered are retinal vascular disease, chronic simple glaucoma, atypical forms of toxic amblyopia, optic neuritis, and optic nerve compression. Meadows (...

Twenty three patients with traumatic optic neuropathy were managed by medical and surgical treatment as follows. High dose intravenous steroids were initiated in all patients. If visions did not improve significantly after 24 to 48 hours decompression of an optic nerve sheath haematoma by medial orbitotomy and neurosurgical decompression of the optic canal were considered based on computed tomo...

Glaucoma is a chronic eye disease that leads to blindness. This disease cannot be cured but we can detect the disease in time. Current tests using intraocular pressure (IOP) measurement are not sensitive enough for population based glaucoma screening. Optic nerve head assessment in retinal fundus images is more promising and superior than current methods. This paper proposes segmentation of opt...

BACKGROUND To report a rare condition of bilateral optic disc pit in a child. CASE DESCRIPTION A ten-year-old female was admitted with a complaint of headache. Visual acuity was 20/20 in both eyes (OU). Anterior segment examination was normal in OU. Fundus examination revealed optic disc pit (ODP) located temporally with a diameter of 1/5 disc diameter in OU. Intraocular pressure was within n...

Ten patients (14 eyes) with chronic simple glaucoma are described, each with features atypical for this disease and more suggestive that each had suffered an acute ischaemic optic neuropathy. Diagnosis of an acute ischaemic optic neuropathy in these cases is important, as treatment of ocular hypertension in the contralateral 'normal' eye may prevent a similar attack. Optic nerve disease and vis...

The records of all patients undergoing optic nerve sheath decompression for visual failure in chronic raised intracranial pressure performed over a 15 year period have been reviewed. The aim was to study the visual outcome and relation to any shunting procedures. Fourteen patients (20 eyes) were identified in whom follow up information of at least one year was available. Eleven patients had ben...

Swelling of the optic disc may result from inflammation, infiltration, nerve compression or ischaemia, as well increased intracranial pressure. It can be imitated by local structural features leading to pseudopapilloedema. Disease entities swelling take different courses in paediatric population compared adult population. Investigations used confirm diagnosis include optical coherence tomograph...

Purpose The prevailing view is that the human retina is supplied by the central retinal artery (CRA), the short posterior ciliary arteries (SPCAs) support the choroid, and both the CRA and the SPCAs are so-called "end artery" systems. In this study, we investigate whether vascular connections among the retina, choroid, and the optic nerve head (ONH) exist, using selective cannulation and microp...

There is considerable debate about the significance of choroidal invasion of retinoblastoma with regard to metastatic disease. The charts of patients with retinoblastoma were reviewed over a 17 year period to determine the frequency of histopathological choroidal invasion of retinoblastoma and its risk for eventual metastatic disease. Sixty seven of 289 eyes (23%) enucleated for retinoblastoma ...
