morning glory syndrome (mgs) is a rare congenital optic disc anomaly characterized by a funnel-shaped, excavated optic disc surrounded by chorioretinal pigmentary disturbance. the main ophthalomoscopic feature of the mgs is enlarged optic disc with a funnel shaped scleral defect; elevated peripapillary chorioretinal pigmentation; and pale fluffy tissue of glial hyperplasia overlying the optic d...

Introduction. Differentiating pseudopapilledema from papilledema which is optic disk edema and a result of increased ICP (intracranial pressure) is important and can be done with noninvasive methods like orbital ultrasound examination. Method. This was a cross-sectional study in which patients with optic nerve head swelling were referred for LP exam after optic nerve head swelling diagnosis con...

One of the major causes of misdiagnosis of papilledema is buried drusen of the optic nerve head [1, 2]. Optic nerve drusen are calcified concretions of unknown etiology, located within the optic nerve head just anterior to the lamina cribrosa. As these concretions enlarge they may become visible ophthalmoscopically. When buried in the nerve head, they may cause difficulties in the ophthalmoscop...

Coriandrum sativum (coriander) has been documented as a traditional treatment of diabetes. On the base of this belief and as the studies about whether coriander reduces hyperglycemia in diabetic mice is little known are lacking, we decided to evaluate the effect of Aqueous Extract seed of Coriander on optic nerve in Balb/c Diabetic Mouse. In the present study, the beta cells of pancreas of 16 b...

AIM To evaluate and compare four different mathematical formulas for the early detection of morphometric optic nerve head changes in chronic open angle glaucoma. METHODS The optic nerve heads of 161 patients with perimetrically defined glaucomatous optic nerve damage and of 194 normal subjects were examined by confocal laser scanning tomography. Using four formulas of linear discriminant anal...

The visual evoked potential (VEP) recording is widely used in clinical practice to assess the severity of optic neuritis in its acute phase, and to monitor the disease course in the follow-up period. Changes in the VEP parameters closely correlate with pathological damage in the optic nerve. This protocol provides a detailed description about the rodent model of optic nerve microinjection, in w...

The detection of the optic nerve in retina images is a key element of detecting the anatomical structure of the retina. In this work we report on the fusion of two complementary optic nerve detection methods. The methods are complementary in the sense that they use different fundamental queues for locating the optic nerve. By fusing the methods through applying simple distance-based threshold, ...

Optic nerve head is part of the retina where ganglion cell axons exit the eye to form the optic nerve. Glaucomatous changes related to loss of the nerve fibers decrease the neuroretinal rim and expand the area and volume of the cup. Therefore optic nerve head evaluation is important for early diagnosis of glaucoma. This study implements the detection of the optic nerve head in retinal fundus im...

BACKGROUND/AIM Vascularisation of the distal, namely intracranial and intracanalicular parts of the optic nerve have not been explained in conventional textbooks of anatomy, while there have been explanations of proximal, that is intraorbital segment. The aim of this research was to study the pattern of arterial supply of the intracranial and intracanalicular part (the distal part) of human opt...

PURPOSE The purpose of this study was to demonstrate whether the pattern of optic nerve enhancement in magnetic resonance imaging (MRI) can help to differentiate between idiopathic optic neuritis (ON), neuromyelitis optica (NMO), and multiple sclerosis (MS) in unilateral ON. METHODS An MRI of the brain and orbits was obtained in patients with acute unilateral ON. Patients with ON were divided...
