Multifocal electroretinogram delays predict sites of subsequent diabetic retinopathy.
PURPOSE To examine the potential of abnormal mfERGs to predict the development of diabetic retinopathy at corresponding retinal locations 1 year later. METHODS One eye of 11 diabetic patients with nonproliferative diabetic retinopathy (NPDR) and 11 diabetic patients without retinopathy were retested 12 months after initial testing. At each time, mfERGs were recorded from 103 retinal locations...
متن کاملEffect of short-term hyperglycemia on multifocal electroretinogram in diabetic patients without retinopathy.
PURPOSE To investigate the effect of variations in blood glucose level on the multifocal electroretinogram (mfERG) in patients with type 1 diabetes without retinopathy. METHODS Fourteen patients were clamped sequentially and in random order at 5 and 15 mM blood glucose for 75 minutes on the same day. MfERG was recorded in one eye at each level of blood glucose level. RESULTS Compared to eug...
متن کاملThe multifocal pattern electroretinogram in chloroquine retinopathy.
PURPOSE Optimal screening for ocular toxicity caused by chloroquine and hydroxychloroquine is still controversial. With the multifocal pattern electroretinogram (mfPERG), a new electrophysiological technique has recently become available to detect early changes of ganglion cells. In this study this new technique is applied to a series of 10 patients seen consecutively receiving long-term chloro...
متن کاملRetinal function in normal and diabetic eyes mapped with the slow flash multifocal electroretinogram.
PURPOSE It has been suggested that late components of the standard multifocal electroretinogram (mfERG) are preferentially affected by diabetes mellitus. The slow-flash (sf-)mfERG stimulates with flashes separated by dark periods, facilitating interpretation of late first-order response components compared with standard multifocal stimulation. Retinal function and response component changes wer...
متن کاملThe electroretinogram in minimal diabetic retinopathy.
The pattern and diffuse flash electroretinograms were measured in 20 normal subjects and 40 diabetic patients who had either normal fundi or microaneurysms only. The amplitudes of the pattern electroretinogram were found to be similar in both normals and diabetics. In the case of the flash electroretinogram the diabetic patients showed a division into two main groups. One group was not dissimil...
