    2. The physiological variation of the retinal nerve fibre layer thickness and macular volume in humans as assessed by spectral-domain optical coherence tomography

      The physiological variation of the retinal nerve fibre layer thickness and macular volume in humans as assessed by spectral-domain optical coherence tomography
      Purpose With the introduction of spectral domain optical coherence tomography (SD-OCT), changes in the retinal nerve fibre layer (RNFL) thickness and macular volume (MV) can be detected with a high precision. This study aimed to determine whether there is a physiological quantifiable degree of variation of these structures in humans. Methods This study took place during a 10 km charity run at VU University Amsterdam. Weight, height, hydration status, RNFL ...

    3. Topographic variation and interocular symmetry of macular choroidal thickness using enhanced depth imaging optical coherence tomography

      Topographic variation and interocular symmetry of macular choroidal thickness using enhanced depth imaging optical coherence tomography
      Purpose: To report and analyse factors influencing topographical and interocular variations of choroidal thickness (CT) in healthy adult population. Methods: 100 eyes of 50 healthy subjects underwent visual acuity and axial length measurements and optical coherence tomography with enhanced depth imaging using the Heidelberg Spectralis HRA+OCT. CT at the fovea, and 3 mm nasal, temporal, superior and inferior to the fovea were measured manually. Topographic variation, relative interocular differences ...

    5. Surgical Vision

      Surgical Vision
      The emergence of Minimal Access Surgery (MAS) as a paradigm in modern healthcare treatment has created new challenges and opportunities for automated image understanding and computer vision. In MAS, images recovered from inside the body using specialized devices are used to visualize and operate on the surgical site but they can also be used to computationally infer in vivo 3D tissue surface shape, soft-tissue morphology, and surgical instrument motion. This ...

    8. The structure and function of the macula in patients with advanced retinitis pigmentosa

      The structure and function of the macula in patients with advanced retinitis pigmentosa
      Purpose: To assess the structure and function of the macula in advanced retinitis pigmentosa (RP). Methods: Twenty-nine eyes of 22 patients with RP were compared against 17 control eyes. Time-domain optical coherence tomography (OCT) data were processed using OCTRIMA as a means of quantifying Stratus OCT images. The thickness of the retinal nerve fiber layer (RNFL), ganglion cell layer and inner plexiform layer complex (GCL+IPL), inner nuclear layer and ...

      Clinical Applications of Long-Wavelength (1,000-nm) Optical Coherence Tomography
      Commercial optical coherence tomography (OCT) instruments generally use light sources in the range of 800 to 860 nm. Although imaging with these light sources provides excellent visualization of the retinal architecture, details of structures and abnormalities below the retinal pigment epithelium are often limited. At the same time, the optimal light source wavelength for clinical OCT imaging is unknown. OCT imaging using longer wavelength light (1,050 nm) has several ...

    11. Microperimetry and Optical Coherence Tomography in Acute Macular Neuroretinopathy

      Microperimetry and Optical Coherence Tomography in Acute Macular Neuroretinopathy
      Purpose: To report optical coherence tomography and microperimetry findings in acute macular neuroretinopathy. Methods: Case report. Patients: A single patient with acute macular neuroretinopathy. Conclusion: Scotomata reported by a patient with acute macular neuroretinopathy correspond with findings of disruption of the photoreceptor inner segment-outer segment junction on optical coherence tomography and congruent decreased retinal function demonstrated with microperimetry.

      Spatial Distribution of Posterior Pole Choroidal Thickness by Spectral Domain Optical Coherence Tomography
      Purpose: To study the spatial distribution of posterior pole choroidal thickness (CT) in healthy eyes using spectral domain optical coherence tomography (OCT). Methods: Fifty-nine eyes from 30 subjects with no retinal or choroidal disease were examined with the Cirrus HD-OCT (Carl Zeiss Meditec) using macular volume cube scanning protocols. A randomly chosen-subset also had multi-field analysis performed (volume scans centered on and surrounding the optic nerve head (ONH)). CT was ...

      Multimodal photoacoustic and optical coherence tomography scanner using an all optical detection scheme for 3D morphological skin imaging
      A noninvasive, multimodal photoacoustic and optical coherence tomography (PAT/OCT) scanner for three-dimensional in vivo (3D) skin imaging is described. The system employs an integrated, all optical detection scheme for both modalities in backward mode utilizing a shared 2D optical scanner with a field-of-view of ~13 × 13 mm2. The photoacoustic waves were detected using a Fabry Perot polymer film ultrasound sensor placed on the surface of the skin. The sensor ...
