Evaluation of structure and birefringence properties of post trabeculectomy eyes for glaucoma using optical coherence tomography

我们使用扫描光源和偏振敏感光学相干断层扫描仪评估青光眼小梁切除术后眼睛的结构和双折射特性。我们还测量了正常眼前节，并与其他光学和超声器械进行了比较（Ophthalmology 2009）。我们检测了三维角膜病变并计算了前房体积（Ophthalmology 2009，Cornea 2007）。我们非侵入性地可视化内部水流出通道并计算三维体积。功能良好的成功滤过泡表现为内部充满液体的空腔较大，低反射区较大，滤过泡壁较厚，微囊较多。不成功的滤过泡显示出更大的极化变化（Opt Express 2009）。

We evaluated structure and birefringence properties of post trabeculectomy eyes for glaucoma by using swept-source and polarization-sensitive optical coherence tomography. We also measured normal anterior segment of the eye and compared with the other optical and ultrasound devices (Ophthalmology 2009). We detected three dimensional corneal lesion and calculated volume of the anterior chamber (Ophthalmology 2009, Cornea 2007). We noninvasively visualized the internal aqueous outflow channel and calculated three-dimensional volume. The successful blebs with good function presented large internal fluid filled cavity, greater hypo-reflective area, and thicker bleb walls with more microcysts. The unsuccessful blebs showed greater polarization change (Opt Express 2009).
