Retinal Pathway Origins of the Pattern Electroretinogram (PERG)

Retinal pathway origins of the pattern electroretinogram (PERG).

PURPOSE To determine retinal pathway origins of pattern electroretinogram (PERG) in macaque monkeys using pharmacologic dissections, uniform-field flashes, and PERG simulations. METHODS Transient (2 Hz, 4 reversals/s) and steady state (8.3 Hz, 16.6 reversals/s) PERGs and uniform-field ERGs were recorded before and after intravitreal injections of L-AP4 (not APB) (2-amino-4-phosphonobutyric ac...

[Pattern-reversal electroretinogram (PERG): a normative study in adults].

PURPOSE To determine normative values for pattern-reversal electroretinogram (PERG) in healthy adult volunteers according to the standard protocol recommended by the International Society for Clinical Electrophysiology of Vision-ISCEV. METHODS Participants were 30 healthy volunteers (15 males) with ages from 18 to 61 years (mean= 30.8 +/- 8.7 yrs.; median= 29.5 yrs). Inclusion criteria were: ...

Investigating the frequency characteristics of the electroretinogram signal in patients with central retinal vein occlusion

Background: Central retinal vein occlusion (CRVO) is the second most common retinal vascular disorder after diabetic retinopathy. In this study, we tried to examine the potentials of time-frequency methods for differentiating the eyes with CRVO. Materials and methods: Twenty patients with unilateral CRVO were included in this study. Their contralateral normal eyes were considered as the control...
