INTRODUCTION Melanocytoma of the optic disc is a benign lesion. OBJECTIVE To describe a case of optic disc melanocytoma CASE A 48-year old lady presented with gradual visual impairment associated with a floater. The right eye fundus examination showed a mass uniformly dark black in colour on the optic disc. The mass completely obscured the fluorescence on fluorescein angiography and was thu...

Rapid and accurate detection of glaucomatous damage at its onset or on its progression is desirable for optimum patient management. Tonometry alone is insufficient in ensuring adequacy of therapy; also required are stereoscopic optic disc review and quantitative perimetry. Signs of early optic nerve head damage from primary open angle glaucoma (POAG) include nerve fibre layer haemorrhage, a gen...

Irretrievable loss of vision is the predominant result Glaucoma in retina. Recently, multiple approaches have paid attention to automatic detection glaucoma on fundus images. Due interlace blood vessels and herculean task involved detection, exactly affected site optic disc whether small or big size cup, deemed challenging. Spatially Based Ellipse Fitting Curve Model (SBEFCM) classification sug...

PURPOSE To evaluate the optic disc area of patients with non-arteritic anterior ischemic optic neuropathy (NA-AION) and arteritic anterior ischemic optic neuropathy (A-AION) and compare the results between each other and with those from controls in order to verify the existence and the magnitude of anatomical factors predisposing to the development of anterior ischemic optic neuropathy. METHO...

BACKGROUND For diagnosis and follow-up of glaucoma an exact evaluation of the optic nerve disc and the nerve fiber layer is necessary. METHODS The slit-lamp evaluation of the optic nerve disc and nerve fiber layer is presented as well as the evaluation with the Nerve Fiber Analyzer and the Heidelberg Retina Tomograph. RESULTS Signs of a glaucomatous optic disc include a difference of more t...

The location of the optic disc is of critical importance in retinal image analysis. In this work we improve on an approach introduced in [3] who localised an optic disc region through greylevel morphology followed by snake fitting. We propose and implement both the automatic initialisation of the snake and the application of morphology in colour space. We examine various methods of performing t...

PURPOSE To investigate the optic nerve and macular morphology in patients with optic nerve hypoplasia (ONH) using spectral-domain optical coherence tomography (SD OCT). DESIGN Prospective, cross-sectional, observational study. SUBJECTS A total of 16 participants with ONH (10 female and 6 male; mean age, 17.2 years; 6 bilateral involvement) and 32 gender-, age-, ethnicity-, and refraction-ma...

PURPOSE To assess the symmetry of optic nerve head parameters measured by the Heidelberg Retina Tomograph 3 (HRT 3) between fellow eyes in a normal elderly population. DESIGN Cross-sectional population-based study. METHODS Participants of the Blue Mountains Eye Study 10-year follow-up who did not have optic disc disease, including glaucoma, were included. Optic nerve head parameters measure...

AIMS To compare monoscopic and stereoscopic assessment of the optic disc using novel software for the digital stereoscopic analysis of optic disc stereopairs. METHODS Software was developed for the stereoscopic display of digital optic disc images using an interlaced display method. Neuroretinal rim width was determined at 10 degree intervals around the optic disc using a custom (stereoscopic...
