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...

PURPOSE To evaluate the validity of an automatic computer-aided diagnosis (CAD) system for detection of retinal nerve fiber layer (RNFL) defects on fundus photographs of glaucomatous and nonglaucomatous optic neuropathy. METHODS We have proposed an automatic detection method for RNFL defects on fundus photographs in various cases of glaucomatous and nonglaucomatous optic neuropathy. In order ...

Glaucoma is a chronic eye disease that leads to vision loss. As it cannot be cured, detecting the disease in time is important. Current tests using Intra Ocular Pressure (IOP) are not sensitive enough for population based glaucoma screening. Optic nerve head assessment in retinal fundus images is both more promising and superior. The method to segment optic disc and optic cup using Simple Linea...

PURPOSE To evaluate peripapillary atrophy β (PPA-β) characteristics in highly myopic eyes, using simultaneous confocal scanning laser ophthalmoscopy (cSLO) and enhanced spectral-domain optical coherence tomography (SD-OCT). METHODS The authors retrospectively analyzed 61 highly myopic (≥ -6.0 D) eyes without myopic retinopathy. cSLO fundus images were used to measure the distances from the fo...

conclusions demyelinating disease, anterior ischemic optic neuropathy, non-arteritic anterior ischemic optic neuropathy, autoimmune disease, and hereditary optic neuropathy could cause optic neuropathy. normal cbc parameters and the absence of clinical manifestations of vitamin b12 deficiency could not rule out its diagnosis. careful physical examinations and history-taking with a classical app...

-----------------------------------------------ABSTRACT---------------------------------------------------------GLAUCOMA is a group of diseases that can damage the eye’s optic nerve and result in vision loss and permanent blindness. Glaucoma is a disease characterized by elevated intraocular pressure (IOP). This increased IOP leads to damage of optic nerve axons at the back of the eye, with eve...

Glaucoma is the second leading progressive ocular disorder after cataract caused by degenerative optic nerve head (ONH) structure. To minimize the risk of visual loss and impairment, early detection of glaucoma is needed. Among the various image structural cues for glaucoma detection, most of the clinician considered Cup-to-Disc (CDR) ratio as major factor. Hence, an robust and automated early ...

Background: Stereoscopic assessment of the optic disc morphology is an important part of the care of patients with glaucoma. The aim of this study was to assess stereoviewing of stereoscopic optic disc images using an example of the new technology of autostereoscopic screens compared to the liquid shutter goggles. Methods: Independent assessment of glaucomatous disc characteristics and measurem...

SIGNIFICANCE This study resulted in the identification of an optic nerve head (ONH) feature associated with tilted optic discs, which might potentially contribute to ONH pathologies. Knowledge of such findings will enhance clinical insights and drive future opportunities to understand disease processes related to tilted optic discs. PURPOSE The aim of this study was to identify novel retinal ...
