Eye of the Hurricane

Ultrasound biomicroscopy of a post-operative eye (status post trabeculectomy and phacoemulsification) reveals a patent ostium on the right side, along with an intraocular lens in position. A hyphema is observed displaying small convection currents, creating a circular motion pattern due to the temperature gradient between the iris and cornea. Notably, the blood flow can be seen circulating toward the trabeculectomy site.
