    2. Infrared imaging and spectral-domain optical coherence tomography findings correlate with microperimetry in acute macular neuroretinopathy: a case report

      Infrared imaging and spectral-domain optical coherence tomography findings correlate with microperimetry in acute macular neuroretinopathy: a case report
      Introduction Spectral-domain optical coherence tomography findings in a patient with acute macular neuroretinopathy, and correlation with functional defects on microperimetry, are presented. Case presentation A 25-year old Caucasian woman presented with bitemporal field defects following an upper respiratory tract infection. Her visual acuity was 20/20 in both eyes and a dilated fundus examination revealed bilateral hyperpigmentary changes in the papillomacular bundle. Our patient underwent further evaluation with spectral-domain optical ...

    4. Spectral domain optical coherence tomography features of multiple subfoveal retinal pigment epithelial tears after intravitreal bevacizumab

      Spectral domain optical coherence tomography features of multiple subfoveal retinal pigment epithelial tears after intravitreal bevacizumab
      Retinal pigment epithelial (RPE) tear has been described to occur spontaneously, after laser photocoagulation and in recent times, after intravitreal injection of anti-vascular endothelial growth factor (VEGF) agents. In the latter case, the rapid contraction of the choroidal vascular membrane underneath a serous RPE detachment is believed to be the underlying cause. Preservation of good visual acuity after the occurrence of RPE tear with continued use of intravitreal VEGF agents ...

    5. In-vivo high resolution imaging of optic nerve head drusen using spectral-domain Optical Coherence Tomography

      In-vivo high resolution imaging of optic nerve head drusen using spectral-domain Optical Coherence Tomography
      Background Optic nerve head drusen (ONHD) are white calcareous deposits, seen either superficially on the optic nerve head or buried within it. Diagnosis of ONHD is made by one or more ways: clinical exam, autofluorescence, ultrasound of the optic nerve, CT scan and/or visual field examination. The present study describes features of ONHD based on another diagnostic modality, the spectral-domain OCT (Spectralis). Methods This is an observational case series ...

    6. Sequential spectral domain OCT documentation of retinal changes after branch retinal artery occlusion

      Sequential spectral domain OCT documentation of retinal changes after branch retinal artery occlusion
      Branch retinal artery occlusions (BRAO) are characterized histopathologically by inner retinal edema initially and atrophy in the presence of persistent ischemia. The duration of ischemia leading to irreversible atrophic retinal changes is not clear. Spectral-domain optical coherence tomography (SD-OCT) provides non-invasive detailed in-vivo histological changes in the retina. In this case report, we show sequential in vivo pathological changes seen in the inner retinal layers, in spite of clinical improvement ...

    7. Comparison of Retinal Thickness in Normal Eyes Using Stratus and Spectralis Optical Coherence Tomography

      Comparison of Retinal Thickness in Normal Eyes Using Stratus and Spectralis Optical Coherence Tomography
      Purpose. Spectral-domain optical coherence tomography (SD-OCT) is an advancement over time-domain OCT (TD-OCT) in the imaging of retinal disorders. Retinal thickness measured by SD-OCT differs from that measured by TD-OCT because the delineation of the outer boundary of the retina differs in the two instruments. The present study aims to evaluate this difference by comparing macular thickness, as obtained by Stratus and Spectralis OCT, in subjects without any known retinal ...

    8. Spectral domain optical coherence tomography guided photodynamic therapy for choroidal hemangioma: a case report

      Spectral domain optical coherence tomography guided photodynamic therapy for choroidal hemangioma: a case report
      Introduction Circumscribed choroidal hemangiomas are vascular tumors associated with secondary changes in the overlying retinal pigment epithelium and neuro-sensory retina. Spectral-domain optical coherence tomography, a recent advancement in fundus imaging techniques provides high resolution images of the retina. We describe spectral domain Optical coherence tomography findings in a case of circumscribed choroidal hemangioma which was successfully treated with photodynamic therapy. Case presentation A 41-year-old white male presented with decreased vision ...

    9. Foveal structure defined by spectral domain optical coherence tomography correlates with visual function after macular hole surgery

      Purpose. To study the correlation between final visual acuity after successful anatomic macular hole repair and features on spectral domain optical coherence tomography (SD-OCT). Methods. Retrospective review of charts of patients who underwent macular hole surgery. Data collection included pre- and postoperative best-corrected visual acuity (BCVA), central subfield foveal thickness (CSFT), and presence or absence of inner segment–outer segment (IS-OS) line changes on SD-OCT. Data collected from SD-OCT were ...

    10. Fundus autofluorescence and spectral domain optical coherence tomography in early detection of Plaquenil maculopathy

      Purpose. To report fundus autofluorescence (FAF) and spectral-domain optical coherence tomography (SD-OCT) findings in a patient with early hydroxychloroquine maculopathy. Methods. A 50-year-old man presented with complaints of ring-like shadows in front of his eyes. He had been on hydroxychloroquine (Plaquenil) 400 mg orally twice daily for 10 years (5.14 mg/kg/day). Fundus examination revealed granular hypopigmentation in an arcuate pattern in the inferior parafoveal area bilaterally. The ...

    12. Functional microperimetry and SD-OCT confirm consecutive retinal atrophy from optic nerve pit

      A congenital anomaly, optic nerve pit is often associated with serous retinal detachment involving macula. Long standing serous detachment leads to outer retinal atrophy and decrease in visual sensitivity. Recently, spectral-domain optical coherence tomography (OCT) has been reported to demonstrate a communication between the optic nerve sheath and the subretinal space. Vitreous cavity is proposed as an alternate source of fluid for accumulation in the subretinal space. We imaged a ...

    13. Normative Data for Macular Thickness by High-Definition Spectral-Domain Optical Coherence Tomography (Spectralis)

      Purpose To establish normative data for the macular thickness by spectral-domain optical coherence tomography (SD-OCT) in subjects with no known retinal disease. Design Prospective, observational study in an academic institutional setting. Methods Fifty subjects (age range, 20 to 84 years) with no known retinal disease, best-corrected visual acuity 20/20, and normal intraocular pressure were enrolled. The subjects were divided into 3 age groups: group 1 included subjects 20 to ...
