Fifty-five cases of senile entropion and ectropion have been studied electron microscopically. In both senile entropion and ectropion significant ultrastructural abnormalities were found in the orbicular muscle fibres, such as a disruption of fibres, Z line streaming, rod formation, Z line duplication and cytoplasmic body formation. These alterations have been described only in neuromuscular disorders and systemic diseases affecting the skeletal muscles. Our observations have confirmed that these abnormalities are not specific signs of any given disease, they rather represent the ultrastructural background of impaired muscle function independently of the aetiology of the disease.
对55例老年性睑内翻和睑外翻进行了电子显微镜研究。在老年性睑内翻和睑外翻中,均在眼轮匝肌纤维中发现了明显的超微结构异常,如纤维断裂、Z线流、杆状形成、Z线重复和胞质体形成。这些改变仅在影响骨骼肌的神经肌肉疾病和全身性疾病中有所描述。我们的观察证实,这些异常并非任何特定疾病的特异性体征,它们更代表了肌肉功能受损的超微结构背景,而与疾病的病因无关。
