    2. THREE-DIMENSIONAL ANALYSIS OF SUBMACULAR PERFORATING SCLERAL VESSELS BY ENHANCED DEPTH IMAGING OPTICAL COHERENCE TOMOGRAPHY

      THREE-DIMENSIONAL ANALYSIS OF SUBMACULAR PERFORATING SCLERAL VESSELS BY ENHANCED DEPTH IMAGING OPTICAL COHERENCE TOMOGRAPHY
      Purpose: To analyze submacular perforating scleral vessels (PSVs) using enhanced depth imaging spectral domain optical coherence tomography (EDI-SDOCT). Methods: Twenty-two eyes of 11 healthy women were included in this retrospective study. Central EDI-SDOCT scans (3 x 4.5 x 1.9 mm, 13.5 mm2 scan area) were acquired and postprocessed by denoising, manual sclera segmentation, and PSV investigated by five graders. Results: Mean age was 22.4 +/- 6.2 ...

    3. Assessment of estimated retinal atrophy progression in Stargardt macular dystrophy using spectral-domain optical coherence tomography

      Assessment of estimated retinal atrophy progression in Stargardt macular dystrophy using spectral-domain optical coherence tomography
      Aims To estimate disease progression based on analysis of macular volume measured by spectral-domain optical coherence tomography (SD-OCT) in patients affected by Stargardt macular dystrophy (STGD1) and to evaluate the influence of software errors on these measurements. Methods 58 eyes of 29 STGD1 patients were included. Numbers and types of algorithm errors were recorded and manually corrected. In a subgroup of 36 eyes of 18 patients with at least two ...

    4. An integrated software solution for multi-modal mapping of morphological and functional ocular data

      An integrated software solution for multi-modal mapping of morphological and functional ocular data
      Various morphological and functional techniques for retina examination have been established in the recent years. Although many examination results are spatially resolved and can be mapped onto data originating from other modalities, usually only data from one modality is analyzed by a clinician at a time. This is mainly because there is no software available to the public that enables the registration of structure and function in the clinical setting ...

    5. Spectral Domain Optical Coherence Tomography in Adult-Onset Vitelliform Macular Dystrophy With Cuticular Drusen

      Spectral Domain Optical Coherence Tomography in Adult-Onset Vitelliform Macular Dystrophy With Cuticular Drusen
      Purpose: The purpose of this study was to investigate morphologic differences in a consecutive case series of patients suffering from adult-onset vitelliform macular dystrophy with cuticular drusen (CD) compared with another patient group with a vitelliform lesion only using high-resolution in vivo retinal imaging. Methods: Simultaneous spectral domain optical coherence tomography (870 nm, 40.000 A-scans per second) and confocal scanning laser ophthalmoscopy were performed in 6 patients (12 eyes ...

    6. Outer Retinal Hyperreflective Spots on Spectral-Domain Optical Coherence Tomography in Macular Telangiectasia Type 2

      Outer Retinal Hyperreflective Spots on Spectral-Domain Optical Coherence Tomography in Macular Telangiectasia Type 2
      Purpose: To analyze focal hyperreflective morphologic alterations in outer retinal layers in patients with type 2 idiopathic macular telangiectasia (MacTel type 2) using spectral-domain optical coherence tomography (SD OCT).Design: Cross-sectional case-control study.Participants: Forty-one patients with MacTel type 2.Methods: Anatomic layers were evaluated and compared with those of controls of similar age. Simultaneous SD OCT scans were obtained with a combined confocal scanning laser ophthalmoscope for simultaneous tomographic ...

    7. Clinical evaluation of simultaneous confocal scanning laser ophthalmoscopy imaging combined with high-resolution, spectral-domain optical coherence tomography

      Purpose: To evaluate the clinical relevance of a new diagnostic modality, simultaneous confocal scanning laser ophthalmoscopy (cSLO) and high-speed, high-resolution, spectral-domain optical coherence tomography (OCT), for the visualization of macular pathologies. Methods: OCT images and simultaneous recording of fluorescein angiography, indocyanine green (ICG) angiography, infrared, and blue reflectance ('red-free') or fundus autofluorecence (FAF) images were obtained with a novel imaging device (Spectralis HRA + OCT; Heidelberg Engineering, Heidelberg, Germany). An optically ...

    11. High resolution Spectral Domain-OCT imaging in Geographic Atrophy associated with Age-related Macular Degeneration.

      Purpose: To describe morphological variations in outer retinal layers in eyes with atrophic age-related macular degeneration (AMD) using high-resolution, spectral-domain optical coherence tomography (SD-OCT). Methods: SD-OCT scans were obtained with a combined confocal scanning laser ophthalmoscope (cSLO) and SD-OCT for simultaneous tomographic and topographic in vivo imaging. A total of 81 eyes of 56 patients (mean age 77.8 +/- 7.4) with geographic atrophy (GA) were examined. Morphological alterations were ...
