目的:观察中心性浆液性脉络膜视网膜病变(中浆)的图形视网膜电图(PERG)和图形视诱发电位(PVEP)的表现。方法:检查92例(120眼)正常人、51例(52眼)中浆患者的PERG和PVEP。结果:患眼的PVEP的P100潜伏期和PERGb波潜伏期延长,PVEP的P100振幅和PERG的b波振幅降低,中浆病情重、视力下降明显者,PVEP和PERG的潜伏期均延长明显,波幅亦下降明显。四个观察指标中,以P100潜伏期改变最明显。结论:中浆患者的PERG和PVEP均有改变,有时较视力更敏锐,可客观反映中浆患者的视功能,检查以PVEP更为简便有效。
Objective: To observe the performance of the pattern electroretinography (PERG) and the pattern visual evoked potential (PVEP) of central serous chorioretinopathy (middle pulp). Methods: PERG and PVEP were examined in 92 (120 eyes) normal subjects and in 51 (52 eyes) moderate patients. Results: P100 latency and PERGb latency of PVEP in eyes were prolonged. P100 amplitude of PVEP and b-wave amplitude of PERG were decreased. Serum and severe visual acuity were significantly decreased in PVEP patients. The latency of PVEP and PERG both prolonged significantly and amplitude significantly decreased . Among the four observation indexes, the change of P100 latency was the most obvious. CONCLUSIONS: Both PERG and PVEP in patients with central pulp have changed, sometimes more sensitive than the visual acuity, can objectively reflect the visual function of patients with pulp, check PVEP more simple and effective.
