      Microscope-Integrated Optical Coherence Tomography–Guided Autologous Full-Thickness Neurosensory Retinal Autograft for Large Macular Hole–Related Total Retinal Detachment

      Purpose: To evaluate the feasibility and utility of microscope-integrated optical coherence tomography in patients undergoing full-thickness neurosensory retinal autograft for refractory macular hole (MH)-associated retinal detachment. Methods: We analyzed two eyes of two patients who had undergone a neurosensory retinal autograft for large MH associated retinal detachment. Both cases had microscope-integrated optical coherence tomography–guided placement and sizing of the retinal autograft. Time taken for obtaining microscope-integrated optical coherence tomography images, morphology of the retinal autograft (intraoperative and postoperative), and anatomic and functional outcomes were noted. Results: The first case had optic disc pit–related maculopathy with a large ...

    2. Optical coherence tomography angiography versus fluorescein angiography in diagnosing choroidal neovascularization in chronic central serous chorioretinopathy

      Optical coherence tomography angiography versus fluorescein angiography in diagnosing choroidal neovascularization in chronic central serous chorioretinopathy

      Purpose: Diagnosis of choroidal neovascular membrane (CNVM) is difficult in chronic central serous chorioretinopathy (CCSC) due to overlapping features of both on conventional dye angiography. Optical coherence tomography angiography (OCTA) allows a quick and noninvasive detection of CNVM in these eyes. We compared the fluorescein angiography (FA) features of CNVM with those of OCTA to assess the role of FA in detecting CNVM in CCSC eyes. Methods: Patients with CCSC undergoing FA, spectral domain (SD)-OCT, and OCTA were identified (March 2015–June 2015). Four retina specialists individually reviewed FA images (without OCTA and SD-OCT) to determine whether CNVM was ...

      Distinguishing features of acute Vogt-Koyanagi-Harada disease and acute central serous chorioretinopathy on optical coherence tomography angiography and en face optical coherence tomography imaging

      Background The aim of this study is to determine the differences in optical coherence tomography angiography (OCTA) features of acute Vogt-Koyanagi-Harada disease (VKH) and acute central serous chorioretinopathy (CSC). Clinical and imaging data of patients with acute CSC and VKH in a tertiary-care institute were analyzed. Multimodal imaging including fluorescein angiography, indocyanine green angiography (ICGA), and enhanced-depth imaging OCT were performed. OCTA images were analyzed for alterations in retinochoroidal microvasculature. Results Thirty-four eyes (24 patients; 10 with VKH and 14 with CSC) were included. OCTA en face images showed apparent areas of choriocapillaris flow void due to shadowing effect from ...

    5. Morphological differences between optic disc collaterals and neovascularization on optical coherence tomography angiography

      Morphological differences between optic disc collaterals and neovascularization on optical coherence tomography angiography

      Background To study morphological features of optic disc venous collaterals (OVCs) and neovascularization of optic disc (NVD) on optical coherence tomography angiography (OCTA). Methods Patients with OVCs and NVDs secondary to ischemic retinal diseases were prospectively enrolled. Multimodal imaging was performed using color fundus photography, fluorescein angiography (FA), and OCTA. Morphological evaluation of en-face structural OCT, cross-sectional and en-face OCTA was performed. Results Twenty eyes (20 patients; OVCs: n  = 10 and NVD: n  = 10) were included. OVCs appeared as small, loopy vessels distinct from surrounding peripapillary capillaries on OCTA in the radial peripapillary capillary frame. NVDs appeared as a mesh ...
