摘要： The lacrimal endoscope is applied to the diagnosis and therapy of the disorders of the lacrimal system in combination with laser or micro drills under orthophoria. The changes of mucous membranes, the characteristics of pathological changes and the predilection sites of lacrimal system diseases were initially approached. One hundred and forty six pairs of eyes of 128 patients with lacrimal system disease were observed by the lacrimal endoscope in the Ophthalmology Department of Tongji Hospital from June 2006 to March 2007. The dynamic changes in mucous membranes, lesion sites, secreted substances and formation of membrane could be observed under orthophoria. Combined with laser or micro drill, the endoscope was applied to the therapy of lacrimal system disorders and the difference before and after the treatment was observed. Results are as follows: (1) The examination and therapy using the lacrimal endoscope were completed under topical anesthesia in 122 patients, and 6 patients of neonatorum dacryocystitis were examined and treated under general anaesthesia. All patients reported painless. (2) Sharp images of the lacrimal system were obtained by the endoscope. Normal lacrimal mucosal membrane was smooth and light pink, expanded and unobstructed during irrigation. In chronic dacryocystitis patients, the inhomogeneous colour of mucosal membranes was red and white, with different degrees of fibrotic membranes at the superior, middle and inferior parts of the nasolacrimal canals and secreted substances at sac could be observed. The lacrimal ducts could not be expanded and obstructed during irrigation. The patients with lacrimal system obstruction had different extents of membrane formation, and stenosis or complete obstruction of the lacrimal duct could be observed, and the corresponding mucosal membrane was not smooth which could not be expanded and obstructed during irrigation. (3) After the treatment by the endoscope combined with laser or micro drill, the major proliferation of the membrane disappeared and the lacrimal duct was unobstructed during irrigation. The cure rate and effective rate were 80.1% and 93.1%, respectively. The lacrimal endoscope is a new method in the diagnosis of lacrimal system diseases. Through a combination with laser or micro drill to carry out the therapy under orthophoria, it will bring a great change to the diagnosis and therapy of lacrimal system diseases.

摘要： 在内窥镜临床检查中，病灶尺寸精确估计对诊断具有非常重要的意义。本文提出一种基于深度学习的双目内窥镜三维测量方法，可以克服传统双目匹配算法在弱纹理区域鲁棒性较差的缺点。利用三维扫描仪获得的目标三维数据和三维渲染软件仿真的双目相机创建虚拟双目图像数据集，用于训练视差预测模型进行三维测量。实验结果表明，所提方法相比传统双目匹配算法在视差准确度和视差图生成速度上分别提高48.9%和90.5%，能够提供更加准确、可靠的病灶尺寸信息，提高内窥镜诊断效率。
