    1. Suprachoroidal hemorrhage followed by swept-source optical coherence tomography: a case report

      Suprachoroidal hemorrhage followed by swept-source optical coherence tomography: a case report

      Background To report a case of Suprachoroidal Hemorrhage followed by Swept-Source Optical Coherence Tomography. Case presentation A 66-year-old woman with a rhegmatogenous retinal detachment in her left eye underwent pars plana vitrectomy. During the intraocular photocoagulation for a retinal tear after fluid-air exchange, a vitreous hemorrhage and suprachoroidal hemorrhage (SCH) developed. The surgical incisions were closed after filling the vitreous cavity with silicone oil. Two weeks later, the hemolyzed hemorrhage was removed, and new silicone oil was injected. After the surgery, a low reflective region was detected near the macula in the swept-source optical coherence tomographic (SS-OCT) images. The low ...

      Swept-source optical coherence tomographic findings in eyes with metastatic choroidal tumor

      Purpose To report the swept-source optical coherence tomographic (OCT) findings in two eyes with choroidal metastases. Observations Two patients with choroidal metastasis were studied. The metastasis was from a breast cancer in Case 1 and from a lung cancer in Case 2. In Case 1, swept-source OCT showed a highly reflective solid tumor with low optical reflective tissues that had replaced the choroidal tissue. Swept-source OCT was able to image the choroidal mass where other fundus imaging methods such as fluorescein angiography did not show the mass. Ophthalmoscopy of Case 2 showed hemorrhages in the inner retina, on the tumor ...
