    1. Comparison Of Optical Coherence Tomography Angiographic Changes After Anti–Vascular Endothelial Growth Factor Therapy Alone Or In Combination With Photodynamic Therapy In Polypoidal Choroidal Vasculopathy

      Comparison Of Optical Coherence Tomography Angiographic Changes After Anti–Vascular Endothelial Growth Factor Therapy Alone Or In Combination With Photodynamic Therapy In Polypoidal Choroidal Vasculopathy

      Purpose: To compare changes in optical coherence tomography angiography in eyes with polypoidal choroidal vasculopathy after treatment with anti–vascular endothelial growth factor monotherapy or combined with photodynamic therapy . Methods: This is a longitudinal case-controlled study. The authors performed optical coherence tomography angiography at baseline and Month 3 in patients with treatment-naive polypoidal choroidal vasculopathy undergoing monotherapy (n = 10) or combination therapy (n = 13). We analyzed flow signal within the outer retina and choriocapillaris using automated segmentation. The authors analyzed the presence of pachyvessels using a 10.4- μ m segment through Haller layer . The changes in each layer were compared ...

    2. IMPROVED DETECTION AND DIAGNOSIS OF POLYPOIDAL CHOROIDAL VASCULOPATHY USING A COMBINATION OF OPTICAL COHERENCE TOMOGRAPHY AND OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY

      IMPROVED DETECTION AND DIAGNOSIS OF POLYPOIDAL CHOROIDAL VASCULOPATHY USING A COMBINATION OF OPTICAL COHERENCE TOMOGRAPHY AND OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY

      Purpose: To assess the ability of optical coherence tomography (OCT) alone and in combination with OCT angiography (OCTA) to differentiate polypoidal choroidal vasculopathy (PCV) from neovascular age-related macular degeneration , as compared to fluorescein angiography and indocyanine green angiography. Methods: This is a cross-sectional study. All participants had a standardized history, clinical examination including measurement of best-corrected visual acuity, slit-lamp biomicroscopy, and indirect fundus examination, and underwent standardized imaging (color photography, fluorescein and indocyanine green angiography, OCT, and OCTA) after predefined protocols. We used a 2-step approach (Step 1: spectral domain OCT; Step 2: addition of OCTA) combining structural OCT and ...

We analyzed flow signal within the outer retina and choriocapillaris using automated segmentation. The authors analyzed the presence of pachyvessels using a 10.4-[mu]m segment through Haller layer. The changes in each layer were compared ...

    4. CHARACTERIZATION AND DIFFERENTIATION OF POLYPOIDAL CHOROIDAL VASCULOPATHY USING SWEPT SOURCE OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY

      CHARACTERIZATION AND DIFFERENTIATION OF POLYPOIDAL CHOROIDAL VASCULOPATHY USING SWEPT SOURCE OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY

      Purpose: To determine the correlation and agreement between swept-source optical coherence tomography angiography (SS-OCT-A) with fluorescein angiography (FA), indocyanine green angiography (ICGA) and spectral domain OCT (SD-OCT) in characterizing polypoidal choroidal vasculopathy (PCV) and in differentiating eyes with typical age-related macular degeneration (t-AMD). Methods: This study included 32 and 54 eyes with t-AMD and PCV, respectively, who underwent SS-OCT-A, SD-OCT, fluorescein angiography, and indocyanine green angiography. The images from these four techniques were compared. Results: On SS-OCT-A, flow signals with vascular network configuration were detected in 81.2% and 77.8% of eyes with t-AMD and PCV, respectively. 40.4 ...

    5. Spectral domain optical coherence tomography imaging in optic disk pit associated with outer retinal dehiscence

      Spectral domain optical coherence tomography  imaging in optic disk pit associated with outer  retinal dehiscence

      A 37-year-old Bangladeshi male presented with an inferotemporal optic disk pit and serous macular detachment in the left eye. Imaging with spectral domain optical coherence tomography (OCT) revealed a multilayer macular schisis pattern with a small subfoveal outer retinal dehiscence. This case illustrates a rare phenotype of optic disk maculopathy with macular schisis and a small outer retinal layer dehiscence. Spectral domain OCT was a useful adjunct in delineating the retinal layers in optic disk pit maculopathy, and revealed a small area of outer retinal layer dehiscence that could only have been detected on high-resolution OCT.
