Congenital Non-Degenerative Retinal Diseases

Abstract

Electrophysiologic tests are used widely in the objective functional examinations in different retinal diseases for several reasons as follows: (1) Differentiation of those diseases with similar symptoms and results from other examinations. Electrophysiologic tests have different characteristics in different diseases. (2) For quantitatively monitoring of the treatment effect or the development of disease. (3) Electrophysiologic tests are more sensitive than other examinations in some diseases. (4) For those patients (e.g., pediatric patients, elderly patients, psychiatric patients, or the patients that intend to bias the results of examinations) who are uncooperative in performing some examinations (e.g., perimetry and visual acuity test). This chapter summarizes the application of electroretinogram and/or visual evoked potential in patients with congenital stationary night blindness, Oguchi disease, fundus albipunctatus, achromatopsia, blue cone monochromatism, and mutations of paired box 6 gene.
