本文将40名清亮角膜移植病例按5岁前或后发生角膜混浊分为二组研究其弱视及注视的分型。5岁前发生单侧角膜混浊且角膜移植术迟至10～30岁时方施行,则发生有旁中心注视的不可逆的严重弱视。若为双侧混浊,即使发病于5岁前,角膜移植后,视力增进可发生于较好的一眼,并有中心注视。混浊发生于5岁以后,则角膜移植术后可有良好的视力,此种病例多为中心注视型,术前有斜视的病人无一例术后斜视角消失。但在B组中有4例于术后成为交替性斜视。
In this paper, 40 patients with clear corneal transplants were divided into two groups according to corneal opacities before or after 5 years old to study the classification of amblyopia and gaze. Unilateral corneal opacity occurs before the age of 5 and corneal transplantation is performed as late as 10 to 30 years of age and there is an irreversible severe amblyopia with a side-center gaze. If bilateral opacity, even in the incidence of 5 years ago, after the corneal transplantation, visual acuity can occur in the better one, and the center of attention. Occurrence of opacity after 5 years of age, the corneal transplantation after surgery may have good vision, such cases are mostly central gaze, preoperative strabismus patients without any strabismus disappeared. However, in group B, 4 patients became alternative strabismus after surgery.
