      Spectral domain optical coherence tomography predates fluorescein angiography in diagnosing central serous chorioretinopathy
      Dear Editor: Central serous chorioretinopathy (CSCR) is characterized by the development of serous retinal detachment in the macula and is mainly diagnosed by fluorescein angiography that shows one or multiple areas of leakage from the retinal pigment epithelium (RPE) seen as "expanding dot" or "smoke stack" sign. [1],[2] The RPE defect corresponding to the dominant hyperfluorescence in the fluorescein angiogram, is believed to be the cause for serous leakage of fluid into the subretinal space and is seen as a pigment epithelium detachment (PED) on time domain Stratus Optical coherence tomography (OCT). [3] We present a case of CSCR ...

    2. Morphological changes in the retinal pigment epithelium on spectral-domain OCT in the unaffected eyes with idiopathic central serous chorioretinopathy

      Abstract  Purpose To report the changes seen in the retinal pigment epithelium (RPE) morphology in the asymptomatic eyes of patients with idiopathic central serous chorioretinopathy (ICSC) using spectral-domain Cirrus TM high-definition optical coherence tomography (HD-OCT). Methods In a prospective case series, 17 consecutive patients with unilateral ICSC underwent spectral-domain Cirrus TM HD-OCT scans for both affected and opposite asymptomatic eye. Three-dimensional single-layer RPE map was studied in both eyes for morphological alterations, and findings were correlated with clinical presentation, fluorescein angiogram, and 5 Line raster scan. Additionally, three-dimensional (3D) single-layer RPE maps done in 111 healthy volunteers served as control ...

    3. Spectral-Domain Cirrus Optical Coherence Tomography of Choroidal Striations Seen in the Acute Stage of Vogt-Koyanagi-Harada Disease

      Purpose: To describe changes in the retinal pigment epithelium (RPE) corresponding to the choroidal striations in acute-stage Vogt-Koyanagi-Harada (VKH) disease.Design: Prospective, consecutive case series.Methods: Four patients (eight eyes) with acute-stage VKH disease were studied. All underwent fundus fluorescein angiography (FFA), ultrasonography, and spectral-domain optical coherence tomography (SD OCT). The main outcome measure was the correlation of the findings seen on a 3-dimensional (3D) single-layer RPE map constructed on SD OCT with the serous retinal detachment (RD) and choroidal striations.Results: The retina inner to external limiting membrane did not show any structural alteration in any of the eyes ...
