| Research Abstract |
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).
