AIMS To evaluate the ability of the confocal scanning laser ophthalmoscope (TopSS) to detect early glaucomatous visual field defect using our unique discriminant criteria. METHODS The optic discs of 110 eyes of normal Korean subjects were examined and normal values for each variable were obtained according to the size of the optic disc. The five most sensitive optic disc variables for discrim...

This study was to analyse the degeneration of the Retinal Nerve Fiber Layer (RNFL) and optic disc and the relationship between optic nerve damage and the severity of cognitive impairment in patients with Alzheimer’s disease (AD) and Mild Cognitive Impairment (MCI). The RNFL thickness and optic disc variables were assessed by optical coherence tomography in patients with MCI and AD and control s...

BACKGROUND Non-proliferative diabetic retinopathy is the early stage of diabetic retinopathy. Automatic detection of non-proliferative diabetic retinopathy is significant for clinical diagnosis, early screening and course progression of patients. METHODS This paper introduces the design and implementation of an automatic system for screening non-proliferative diabetic retinopathy based on col...

PURPOSE To measure the optic disc rotation around the vertical and horizontal disc axis and to evaluate associations with general and ocular parameters. DESIGN Population-based study. METHODS In the Beijing Eye Study, 3468 participants (mean age:64.6±9.8 years; range:50-93 years) underwent an ophthalmological examination which included spectral-domain optical coherence tomography (OCT) with...

PURPOSE To examine the influence of body height, body weight, and body mass index (BMI) on optic disc parameters in a population-based study. METHODS The Singapore Malay Eye Study examined 3280 persons of Malay ethnicity, aged 40 to 80 years, of whom 2329 (71.0%) had reliable retinal scanning confocal laser tomography images for analyses. Intraocular pressure (IOP) was ascertained by Goldmann...

PURPOSE To determine the frequency of optic disc hemorrhages in a rural Indian population. METHODS The population-based Central Indian Eye and Medical Study included 4711 subjects. Mean age was 48.5±12.9 years (range: 30-100 years). Color optic disc photographs were examined. RESULTS Optic disc photographs were available for 4570 (97.0%) subjects. Prevalence of disc hemorrhages was 17/8869 ...

BACKGROUND Optic disc drusen, which are calcified deposits that form anterior to the lamina cribrosa in the optic nerve, may mimic papilledema. CASE REPORT We report herein three cases referred to us with suspicion of disc swelling and papilledema. Following ophthalmologic evaluation with B-scan ultrasound, red-free fundus photography, and computed tomography, the diagnosis of papilledema was...

purpose: to present a case of herpes zoster ophthalmicus (hzo) with consequent posterior ischemic optic neuropathy (pion). case report: a 58-year-old woman with a history of hzo in her right eye which was under treatment presented with loss of vision to no light perception. on examination, positive relative afferent pupillary defect was detected; however the optic disc was normal on ophthalmosc...

OBJECTIVE To assess the relationship between in vivo measurements of optic disc topography and histomorphometric measurements of optic nerve fiber number in glaucoma. METHODS Both eyes of 10 monkeys (Macaca fascicularis) with laser-induced glaucoma in the right eye were studied. Optic disc topography was measured in vivo with a confocal scanning laser ophthalmoscope. Histomorphometry was perf...
