purpose
To study the visual electrophysiological changes in patients with chronic glomerulonephritis.
Methods
The visual evoked potentials(VEP) and electroretinogram(ERG) of 26 subjects with chronic glomerulonephritis in 51 eyes were recorded.
Results
Ours studies showed the patients with chronic glomerulonephritis had pathologic visual electrophysiologic abnormalities.The N 75 peak latency,b wave peak latency O 1 peak latency and total amplitude of OPs in chronic glomerulonephritis patients without fundus sign showed remarkable difference.
Conclusion
These changes suggested visual electrophysiological examination may be valuable in early diagnosis of retinal disfunction in patients with chronic glomerulonephritis.
