0 05). Conclusion ICGA using the Topcon 50IA could be performed prior to the recording of the Ganzfeld ERG.

To elevate the treatment efficiency of infusion needles and decrease the needlestick injuries in clinical works, we devised a machine which can separate the infusion needles automatically. It played an ideal effect when used in clinical works. So we believe that it is worthy of clinical popularization because of its abilities to separate infusion needle automatically and prevent needlestick injury.

OBJECTIVETo investigate the characteristics of multifocal electroretinograms (mf-ERG) of different phases in diabetic retinopathy (DR) and its clinical significance.

METHODSMultifocal electroretinograms in patients with DR (I - II stage) were tested with VERIS IV system.

RESULTSIn I - II stage, the absolute values of N1, P1 and N2 response densities, and the N1-P1 and P1-N2 response densities were attenuated is a field of about 45 degrees in diameter.

CONCLUSIONAs a new objective and quantitative examination for spatial visual function, multifocal electroretinograms may be valuable in the diagnosis of diabetic retinopathy.
