The role of pattern-reversal electroretinography in the diagnosis of glaucoma.
Pattern electroretinography is used to assess the function of the inner retinal layers, particularly the retinal ganglion cell layer, using a reversing checkerboard or grating pattern that maintains a constant overall mean luminance over time. A normal transient response comprises a positive component of the wave (P50) followed by a longer negative component of the wave (N95). Glaucomatous opti...
متن کاملPattern Electroretinography in Glaucoma Suspects and Early Primary Open Angle Glaucoma
PURPOSE To explore retinal ganglion cell (RGC) dysfunction in glaucoma suspects and patients with early primary open angle glaucoma (POAG) using pattern electroretinography (PERG). METHODS Twenty glaucoma suspects (glaucomatous optic disc appearance), 15 early POAG (based on abnormal discs and abnormal visual fields) and 16 normal controls were enrolled. Transient PERG was recorded in respons...
متن کاملPattern Electroretinography Changes in Patients with Established or Suspected Primary Open Angle Glaucoma.
PURPOSE To assess pattern electroretinogram (PERG) changes in patients with established or suspected primary open angle glaucoma (POAG). MATERIALS AND METHODS Transient PERG using LV Prasad eye electrodes were performed in 76 normal, 32 glaucomatous and 22 glaucoma suspect eyes. The P50 amplitude, N95 amplitude and P50 latency were analyzed. The results were further analyzed with receiver ope...

متن کاملGlaucoma: diagnosis and management.
Glaucoma is the third most prevalent cause of global blindness, accounting for over 5 million blind. It is common in Western Countries; the estimated prevalence of primary open angle glaucoma rises from a total prevalence of 1.1% to approximately 3% of our population as it ages. Ethnicity affects both the risk of developing glaucoma and the outcome. It is an expensive disease both to detect and...
