Abstract
Objective To study the relationship between myopia progression and foveal centralis multifocal ERG ( mfERG) response in children .Methods Totally 26 patients who presented to our clinic between January 2011 and De-cember 2013 were enrolled in this study .Average age was 10.6 ±1.2, range from 9 to 13 years.Ophthalmic examinations , including objective and subjective refraction , axial length, and mfERG, were followed for 1 year.Results The progres-sion of myopia related to the increase in axial length (Pearson correlation r =-0.70, P <0.001).Multifocal ERG results showed that DC amplitude was reduced for 96% contrast , and both DC and IC amplitudes were reduced in all fields for 49% contrast.IC amplitude was reduced in ring 1 and ring 2, but slightly increased in ring 3 and ring 4 for 96%contrast. IC latency was shortened for both 49%contrast and 96%contrast , whereas DC latency increased in ring 1 and ring 2 and reduced in ring 3~5 for 49%contrast.DC latency slightly increased in all areas except ring 1 for 96% contrast.In the time domain, the progression of myopia related to the decrease of DC and IC amplitude in ring 1 for 49%contrast (Pearson correlation, r =0.50 ~0.50, P <0.01).DC and IC latencies in most fields were not affected , except DC latency in ring 3 for 49%contrast ( r =0.54, P <0.01) and IC latency in ring 5 ( r =0.49, P =0.49) for 96%contrast.Con-clusion In the children aged lower than 10, myopia progression is associated with decrease of central and paracentral fove-al function .关键词
