Electroretinogram in Retinal Hypertension and Arteriosclerosis

Electroretinogram in Hereditary Retinal Disorders

Investigating the frequency characteristics of the electroretinogram signal in patients with central retinal vein occlusion

Background: Central retinal vein occlusion (CRVO) is the second most common retinal vascular disorder after diabetic retinopathy. In this study, we tried to examine the potentials of time-frequency methods for differentiating the eyes with CRVO. Materials and methods: Twenty patients with unilateral CRVO were included in this study. Their contralateral normal eyes were considered as the control...

Lipoprotein(a), homocysteine, and retinal arteriosclerosis

PURPOSE Elevated levels of lipoprotein(a) [Lp(a)] and homocysteine (Hcy) have been implicated as risk factors for vascular diseases. The study was performed to explore the possible relationship between retinal arteriosclerosis and serum Lp(a) and Hcy levels. METHODS Study subjects consisted of 80 nonsmoking male patients with retinal arteriosclerosis and 54 healthy nonsmoker males as controls...

The eye in general vascular disease: hypertension and arteriosclerosis.

THE HUMAN eye is a natural transparent chamber and its retinal vascular system is easily accessible to direct and repeated observations in vivo. The behaviour of its arterioles, capillaries, and venules in health and disease should provide data applicable to the study of systemic vascular disorders. With the introduction of the ophthalmoscope, a little over a hundred years ago, abnormal fundus ...

Electroretinogram and visual-evoked potential assessment of retinal and central visual function in a rat ocular hypertension model of glaucoma.

PURPOSE/AIM The aim of the study was to investigate the long-term functional changes that may occur in the retina and visual cortex in a rat ocular hypertension (OHT) model of glaucoma, used in our lab for treatment studies, using electroretinogram (ERG) and visual-evoked potential (VEP) cortical recordings in order to test the hypothesis that experimental glaucoma has differential retinal and ...
