    10. Sequential Optical Coherence Tomographic Angiography for Diagnosis and Treatment of Choroidal Neovascularization in Multifocal Choroiditis

      Sequential Optical Coherence Tomographic Angiography for Diagnosis and Treatment of Choroidal Neovascularization in Multifocal Choroiditis
      This case report describes choroidal neovascularization in multifocal choroiditis diagnosed using optical coherence tomographic angiography. Accurate diagnosis of choroidal neovascularization (CNV) is critical to ensure timely antivascular endothelial growth factor therapy and preclude loss of visual acuity. Dye-based angiography is the gold standard for CNV diagnosis; however, it is invasive, is associated with risk of allergy, and may be limited by availability. Optical coherence tomography (OCT) angiography (OCTA) is a ...

    12. Confirmation of Choroidal Varix Through Divot Sign on Spectral-Domain Optical Coherence Tomography

      Confirmation of Choroidal Varix Through Divot Sign on Spectral-Domain Optical Coherence Tomography
      Enhanced depth imaging spectral-domain optical coherence tomography (EDI SD-OCT) provides a rapid and easily accessible measure to evaluate suspicious choroidal lesions. A 60-year-old woman was referred for evaluation of an inferotemporal slightly pigmented lesion that showed a large hyporeflective elevation in the deep choroid on EDI SD-OCT. After applying pressure to the globe, repeat EDI SD-OCT showed flattening of the lesion with a prominent depression or divot within the choroid ...

    13. Association of Choroidal Neovascularization and Central Serous Chorioretinopathy With Optical Coherence Tomography Angiography

      Association of Choroidal Neovascularization and Central Serous Chorioretinopathy With Optical Coherence Tomography Angiography
      Importance Choroidal neovascularization (CNV) is a major cause of vision loss in chronic central serous chorioretinopathy (CSCR). Detecting CNV using fluorescein angiography (FA) may be challenging owing to the coexistence of features related to the primary diagnosis of CSCR. Optical coherence tomography angiography (OCTA) allows noninvasive visualization of retinal and choroidal vasculature via motion contrast and may contribute to the unequivocal diagnosis of CNV in this population. Objective To evaluate ...
