Objective:To observe the retinal function of macular disease with multi focal electroretinogram (M ERG). Methods:16 patients with monocular macular diseases (central serous retinopathy,senile macular degeneration,traumatic macular hemorrhage) were applied the M ERG with short binary M sequence and the full field F ERG (Ganzfeld F ERG) with ISCEV standard,respectively.The first order kernel (FOK) of M ERG and the maximal combined response (MCR) between affected eye and normal eye of F ERG were analyzed,and...

Objective:To observe the retinal function of macular disease with multi focal electroretinogram (M ERG). Methods:16 patients with monocular macular diseases (central serous retinopathy,senile macular degeneration,traumatic macular hemorrhage) were applied the M ERG with short binary M sequence and the full field F ERG (Ganzfeld F ERG) with ISCEV standard,respectively.The first order kernel (FOK) of M ERG and the maximal combined response (MCR) between affected eye and normal eye of F ERG were analyzed,and the retinal functions were evaluated. Results:In all affected eyes,the P1 wave amplitudes of M ERG in ring1 were significantly declined (P<0 01),and the latencies were shortened than that of the fellow normal eye (0 010 05).The amplitudes and latencies of the MCR of F ERG a,b waves had no statistic differences (P>0 05).In normal eye,the P1 wave of ring1 had the highest amplitude and the longest latency among all rings. Conclusions:Macular diseases can decline the amplitude and shorten the latency of the central ring1 (0~5°) area around the macular fovea of FOK.Short binary M sequence recording that has shorter cycle and fewer samples may more suitable for the patient who has poor fixation capability or bad test cooperation.With different kernel responses,M ERG can reflect the functions of the outer layer (photoreceptor layer) and the inner layer (ganglion cell layer) of the retina.It is unique to evaluate the posterior pole,especially the macular retinal function,which is superior to the ordinary Ganzfeld ERG.

Objective We respectively record the retinal linear component (first order kernel, FOK) and non-linear component (second order kernel, SOK) applied with the multifocal electroretinogram(M-ERG) so as to understand whether the abnormality of different layers or parts of the retinal function exist in the amblyopic eyes. Methods Eighteen cases of mono-ocular amblyopia were observed. They were examined by far-eyesight and near-eyesight acuity, scotoscoped with the pupil enlarged, and synoptophore testing. They were diagnosed according to the protocol issued by the National Amblyopic Scientific Group in 1987.We used the M-ERG made in Roman Roland Company (RETI-scan 3.15 version) to examine them by FOK and SOK.Results of 5 rings and 61 hexagons circled by the macular fovea. The results were applied comparative t-test to perform statistical analysis.Results (1) There was no difference in FOK reaction of the density value of amplitude of different rings to the other eye of the same patient (P>0.05);(2) The amplitude density value of the first ring in SOK reaction is obviously lower than that of the other eye of the same patient(P<0.01) ;(3) There was no statistical difference in the amplitude density value of the 2~5 rings in SOK reaction to the other eye of the same patient(P>0.05); (4) There was no statistical difference in the latency of different rings in FOK and SOK to the other eye of the same patient (P>0.05); (5) There was no statistical difference between the two groups in F-ERG.Conclusion (1) There exists no abnormal change and no damage in the light-sensitive cell lamina of retina in amblyopic eyes; (2) Maybe in the interior retina lamina, there has x-type ganglion cellular damage in macular part in amblyopic eyes; (3) There is no abnormal change in retinal lamina about the visual stimulation transmission in amblyopic eyes.

Objective To observe the primary open angle glaucoma (POAG) applying with the m ERG first order kernel (FOK) and the second order kernel (SOK). MethodsWe used the multi focal electrophysiological examination system (RETIscan 3.15 version) and the OCTOPUS101 computer visual field analysis appliance. Examined 33 normal subject eyes and selected 42 eyes of glaucoma and 16 eyes of ocular hypertension (suspected glaucoma), dividing into early, middle and late stage glaucoma. Four parameters of P and N wave of the amplitude and latency of FOK and SOK were recorded. The SPSS8.0 software of statistics analyzed the primary data.Results (1) From the suspected to the early stage, middle stage and late stage glaucoma groups, the amplitude of P wave and N wave gradually decreased, the latency of P wave and N wave gradually prolonged; (2) In sum reaction, the amplitude of P wave in FOK and amplitude of N wave in SOK was significantly different in the early stage, middle stage and late stage glaucoma groups, normal collative group ( P <0.05); (3) The latency of N wave in FOK and the latency of P wave in SOK was significantly different between the middle stage and late stage glaucoma and normal collative group ( P <0.05);(4) In the quadrantal reactions between the suspected glaucoma group and normal collative group, it was significantly different in the superior nasal quadrantal P wave amplitude in SOK and interior nasal , interior temporal quadrantal N wave amplitude( P <0.05).Conclusion FOK and SOK is a more sensitive method in examining glaucoma, especially their quadrantal reactions, than the abnormality of the visual field damage can manifest.
