L\u2019hypoplasie du nerf optique (ONH) est une anomalie cong\u00e9nitale dans laquelle le nerf optique est sous-d\u00e9velopp\u00e9 (petit) et caract\u00e9ris\u00e9 par un nombre r\u00e9duit d’axones. Elle peut se pr\u00e9senter unilat\u00e9ralement ou bilat\u00e9ralement.<\/p>\n

Au fond, l\u2019hypoplasie du disc peut appara\u00eetre grise ou p\u00e2le et elle est souvent entour\u00e9e par un halo p\u00e9ripapillaire tachet\u00e9, jeune et bord\u00e9 par un anneau hyper ou hypopigment\u00e9. Elle est souvent li\u00e9e \u00e0 la tortuosit\u00e9 s\u00e9lective des veines r\u00e9tiniennes.<\/p>\n

L’acuit\u00e9 visuelle est difficile de pr\u00e9voir sur la base de l’apparence du nerf optique et peut varier de 20\/20 \u00e0 l’absence de perception lumineuse. Les yeux atteints pr\u00e9sentent des anomalies du champ visuel localis\u00e9es. On peut voir un nystagmus si les deux yeux sont impliqu\u00e9s. L\u2019incidence de strabisme augmente en pr\u00e9sence d\u2019ONH. L’\u00e9lectror\u00e9tinogramme est normal dans la plupart des patients.<\/p>\n

L\u2019hypoplasie du nerf optique est souvent associ\u00e9e \u00e0 d’autres anomalies du SNC: absence du septum pellucidum, ag\u00e9n\u00e9sie du corps calleux, anomalies de l’h\u00e9misph\u00e8re c\u00e9r\u00e9bral, anomalies de la glande pituitaire. La dysplasie septum-optique (syndrome de De Morsier) est utilis\u00e9e pour d\u00e9crire l’association entre l\u2019hypoplasie du nerf optique et l’absence du septum pellucidum et l\u2019ag\u00e9n\u00e9sie du corps calleux.<\/p>\n

La plupart des cas d\u2019ONH n\u2019a pas une cause identifi\u00e9e mais l\u2019hypoplasie a \u00e9t\u00e9 associ\u00e9e \u00e0 un diab\u00e8te gestationnel, \u00e0 l’abus d’alcool et des drogues pendant la grossesse, m\u00e9dicaments anti-\u00e9pileptiques pendant la grossesse et \u00e0 jeune \u00e2ge gestationnel (20 ans ou moins).<\/p>\n
