Objective- To determine the possibility of three-dimensional ultrasonography (3DUS) and measurement of optical nerve sheet by this method. Design- Descriptive study. Animals- 10 mixed normal dogs (5males, 5 females), age 1-1.5 year, and weighting 15±5 kg Procedure- 3D ultrasounds of the eyes were evaluated and the normal optical nerves in 3DUS images were measured using Volouson 730 pro....
Background and purpose: Optic neuritis is one of the appearances of Multiple Sclerosis (MS). Progesterone has a protective effect in central nervous system, so, in this study we aimed at investigating the effect of progesterone on myelin repair of the optic chiasm in male rats by studying the genes expression of Olig 2 (marker of oligodendrocyte precursor cells), GFAP (marker of astrocyte...
Introduction: Glaucoma is the most common cause of blindness in some countries. In the meantime, the field of retinal image processing has been proposed in order to provide automatic systems for disease diagnosis. Among the methods of medical image processing, image segmentation is a process of identification and change in the display of an image. The objective of this study was to use t...

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...
OBJECTIVE Inflammation of the optic nerve (optic neuritis) and its sheath (optic perineuritis) can have similar initial clinical presentations. They are less well-defined in the Chinese than in Caucasians, and the aetiology of optic neuritis may also differ depending on ethnicity. The aim of our study was to document the clinical features of acute/subacute optic neuritis/optic perineuritis in C...
introduction patients with hepatitis c are commonly treated with combination of pegylated interferon alfa-2a and ribavirin. less than 1% of patients receiving this treatment experience very uncommon ophthalmological side effects such as optic neuropathy and vision disorder, which are usually subclinical, mild and reversible, not requiring the withdrawal of the treatment. retinopathy is the most...
glaucoma is a major cause of worldwide irreversible blindness. the central role of raised intraocular pressure (iop) is being questioned as many patients continue to demonstrate a clinically downhill course despite initial control of iop. the latest concept of recognizing glaucoma as a multifactorial, progressive, neurodegenerative disease of retinal ganglion cells (rgcss) associated with chara...
