Different diseases of the optic disc may be caused by or lead to abnormal vasculature at the optic nerve head. Optical coherence tomography angiography (OCTA) is a novel technology that provides high resolution mapping of the retinal and optic disc vessels. Recent studies have shown the ability of OCTA to visualize vascular abnormalities in different optic neuropathies. In addition, quantified ...

Optic neuritis is commonly associated with diseases such as Multiple Sclerosis, infections, taking special drugs, etc. but recently we have observed a patient that presented retro bulbar optic neuritis as a manifestation of antiphospholipid syndrome. A 35 y/o young woman with the history of chickenpox admitted to the Qhaem hospital (Mashhad, Iran) with the c/o progressive pain and blurred visio...

Optical coherence tomography angiography (OCTA) is a new modality in ocular imaging which provides high resolution view of the vascular structures in the retina and optic nerve head. This technology has the advantages of being noninvasive, rapid and reproducible. OCTA is becoming a valuable tool for evaluating many retinal and optic nerve diseases. This article provides a brief introduction to ...

Aims. The objective of this paper is to determine the incidence of ophthalmic disease potentially leading to optic nerve disease in Middle Tennessee. Methods. We use a retrospective population-based incidence study design focusing on the population of middle Tennessee and its nearby suburbs (N=3 397 515). The electronic medical records for all patients evaluated or treated at a large tertiary c...

John Glasgow Kerr was the second director of First Western-Style Hospital in China, which an eye hospital. Xi Yi Yan Ke (Ophthalmology in Western Medicine), is translated and compiled by Dr. first published 1871 reprinted 1880, first western medical monograph on ophthalmology China. The book consists 53 sections, covering symptom inquiry, symptom examination, cataract surgery, ophthalmosco...

Optic nerve diseases, such as the glaucomas, lead to changes in the intrapapillary and parapapillary region of the optic nerve head. These changes can be described by the following variables: size and shape of the optic disk; size, shape, and pallor of the neuroretinal rim; size of the optic cup in relation to the area of the disk; configuration and depth of the optic cup; ratios of cup-to-disk...

purpose : to report two patients with spontaneous scleral perforation and bleb formation associated with marfan syndrome (mfs) which one of them also showed bilateral optic nerve dural ectasia. case reports : an 11-year-old girl was referred with progressive myopia. past medical history was negative. slit-lamp examination revealed bilateral scleral thinning and perforation with bleb formation, ...

introduction penetration of a bicycle brake handle into the orbit is a rare and serious type of trauma. globe subluxation due to such trauma has not been previously reported. case presentation a 10-year-old girl presented after falling from a bicycle, which resulted in the handbrake penetrating her right upper eyelid. on examination, the globe was subluxated anteriorly, there was no light perce...

The mature optic nerve cannot regenerate when injured, leaving victims of traumatic nerve damage or diseases such as glaucoma with irreversible visual losses. Recent studies have identified ways to stimulate retinal ganglion cells to regenerate axons part-way through the optic nerve, but it remains unknown whether mature axons can reenter the brain, navigate to appropriate target areas, or rest...

AIMS/BACKGROUND Idiopathic intracranial hypertension (IIH) is a central nervous disorder characterised by abnormally increased cerebrospinal fluid (CSF) pressure leading to optic nerve compression. An indirect estimate of increased CSF pressure can be obtained by the ultrasonographic determination of optic nerve sheaths diameters. Computerised static perimetry is regarded as the method of choic...
