Visual Evoked Potentials in Diabetic Patients

Abstract

Visual evoked potentials (VEPs) were assessed in 50 adult type I (insulin-dependent) and 19 type II (noninsulin-dependent) diabetes mellitus patients and in 54 controls. P100 wave latency was significantly longer in diabetic patients (P less than .001). Twenty-eight percent of diabetic patients had P100 wave latencies above the normal range. There was no correlation between P100 latency and type or duration of diabetes mellitus, quality of metabolic control, or presence of degenerative complications. The significance of VEP abnormalities in diabetes mellitus remains speculative.

Evaluation Of The Role Of Visual Evoked Potentials In Detecting Visual Impairment In Type II Diabetes Mellitus

“…Bartek et al 18 found pattern VEP abnormalities in 77% of diabetic patients and reported that abnormalities did not correlate with the level of retinopathy. Visual evoked potentials (VEPs) were assessed by Algan et al 19 in 50 adult type I (insulin-dependent) and 19 type II (noninsulin-dependent) diabetes mellitus patients and in 54 controls. P100 wave latency was significantly longer in diabetic patients as reported by them.…”

Seeing Beyond Retinopathy in Diabetes: Electrophysiological and Psychophysical Abnormalities and Alterations in Vision

“…Although the durations of diabetes were equivalent, the NIDDM subjects were older. Algan et al (48) also found no significant difference between subjects with IDDM and NIDDM, demonstrating increased P100 latencies in approximately 28% of each group.…”

Ophthalmic markers of the diabetic polyneuropathy

“…Именно ла-тентность Р100 обычно оценивается у пациентов с СД и предполагается, что этот параметр явля-ется потенциальным методом оценки нейропатии у пациентов с диабетом. Исследования продемон-стрировали значительное удлинение латентности Р100 у пациентов с СД по сравнению со здоровы-ми людьми [5]. Также было выявлено снижение амплитуды и удлинение латентности у пациентов с СД при отсутствии ДР, что позволяет предпо-ложить влияние ДПН на зрительные пути [31].…”
