目的 研究 2种不同诱导方法所致鸡近视眼组织病理改变 ,探索其发病机制。方法 雏鸡单眼遮盖或戴凹透镜 ,3周后验光及 A超测定眼轴长 ,摘出眼球 ,行光镜及电镜检查。结果 透镜诱导眼和形觉剥夺眼产生相似的病理形态及超微结构改变 ,主要表现为后极部巩膜软骨层增厚 ,纤维层变薄。视杆细胞外节延长及视网膜色素上皮细胞胞质内吞噬体减少。结论 鸡眼对 2种不同的视觉环境变化作出的反应是相似的
Objective To study the histopathological changes of myopia in chicken induced by 2 different induction methods and explore its pathogenesis. Methods Chick monocular cover or wearing concave lens, optometry and A-ray after 3 weeks to measure axial length, eye excercise, light microscope and electron microscopy. Results Lens - induced eye and deprivation of the eye produced similar pathological changes and ultrastructural changes, mainly manifested as posterior pole scleral cartilage thickening, thinning of the fibrous layer. Rod extension and retinal pigment epithelial cells in the cytoplasm of phagosome reduction. Conclusions Corns’ response to two different visual environment changes is similar
