Abnormal evoked potential latencies in amblyopia.

Abnormal evoked potential latencies in amblyopia.

The latency of the first (P1) and second (P2) major positive waves of the pattern reversal visual evoked potential (VEP) for small checks (15 minutes of arc) was measured in 68 visually normal children and 32 amblyopic children with mild to moderate visual acuity losses. In the normal children there were no P1 and P2 interocular latency differences. The amblyopic children showed longer P1 laten...

The visual evoked response in hysterical amblyopia.

Hysterical amblyopia is a term used to describe a syndrome in which reduction of visual acuity accompanied by contraction of the visual fields occurs in the absence of any organic lesion. This syndrome has been the subject of many reports (Eames, I 947; Yasuna, 1951; Schlaegel and Quilala, 1955; Krill, I967), but no conclusive diagnostic test has yet been established. Spiralling of the visual f...

Diagnostic value of prolonged latencies in the vestibular evoked myogenic potential.

BACKGROUND As a parameter for the evaluation of the vestibular evoked myogenic potential (VEMP), amplitude has been used clinically. However, the significance of latency has not been considered. OBJECTIVE To clarify the diagnostic value of latencies of the VEMP. DESIGN We reviewed records of the VEMP of patients with various diseases and compared them with records of healthy volunteers. S...
