  • Title: The pattern-elicited electroretinogram. I. A tool in the early detection of glaucoma?
    Author: Ringens PJ, Vijfvinkel-Bruinenga S, van Lith GH.
    Journal: Ophthalmologica; 1986; 192(3):171-5. PubMed ID: 3725315.
    Abstract:
    The pattern-elicited electroretinogram (PERG) was recorded in 75 patients known with glaucoma, each one of them having a normal visual acuity, and compared with the results in normal test subjects. Although there is a great overlap between normal and glaucomatous eyes, a lower average amplitude and a delay in latency is recorded in the case of glaucoma. A correlation was sought between the PERG outcome on the one hand and different glaucomatous parameters (visual field loss, intraocular pressure, cup disc/ratio) on the other; this could only be confirmed for the cup/disc ratio. In beginning glaucoma the PERG is more often disturbed than the VECP.
