Abstract
Single flash scotopic and photopic electroretinograms (ERGs) were recorded from the same subjects using six types of corneal electrode, in order to assess their relative effectiveness. In addition, the ERG from a lower eyelid skin electrode was recorded to give an indication of the degree of attenuation to be expected from a skin electrode. On average, the scotopic ERG recorded from the Burian Allen electrode measured 471 µ? (100%), and relative to this the b-waves recorded using other electrodes were as follows: JET (89%), C-glide (77%), gold foil (56%), DTL (46%) and skin (12%). Under photopic conditions the order was the same and the interelectrode proportions similar. The b-wave amplitude recorded using the Burian Allen electrode was 125 µ? (100%), and with other electrodes was as follows: JET (93%), C-glide (78%), gold foil (60%), DTL (60%) and skin (14%).
为了评估六种角膜电极的相对效果，我们使用六种角膜电极记录了同一受试者的单闪散光和光视视网膜电图（ERG）。此外，还记录了来自下眼睑皮肤电极的ERG，以显示皮肤电极的预期衰减程度。平均而言，布里安-艾伦电极记录的光斑 ERG 测量值为 471 µ?(100%），相对于此，使用其他电极记录的 b 波如下：JET（89%）、C-glide（77%）、金箔（56%）、DTL（46%）和皮肤（12%）。在光照条件下，顺序相同，电极间比例相似。使用 Burian Allen 电极记录到的 b 波振幅为 125 µ?(100%），使用其他电极记录的 b 波振幅如下：JET（93%）、C-glide（78%）、金箔（60%）、DTL（60%）和皮肤（14%）。
期刊介绍：
Eye seeks to provide the international practising ophthalmologist with high quality articles, of academic rigour, on the latest global clinical and laboratory based research. Its core aim is to advance the science and practice of ophthalmology with the latest clinical- and scientific-based research. Whilst principally aimed at the practising clinician, the journal contains material of interest to a wider readership including optometrists, orthoptists, other health care professionals and research workers in all aspects of the field of visual science worldwide. Eye is the official journal of The Royal College of Ophthalmologists.
Eye encourages the submission of original articles covering all aspects of ophthalmology including: external eye disease; oculo-plastic surgery; orbital and lacrimal disease; ocular surface and corneal disorders; paediatric ophthalmology and strabismus; glaucoma; medical and surgical retina; neuro-ophthalmology; cataract and refractive surgery; ocular oncology; ophthalmic pathology; ophthalmic genetics.
