      Assessment of Differential Pharmacodynamic Effects using Optical Coherence Tomography in Neovascular Age-Related Macular Degeneration
      Purpose: To assess the differential pharmacodynamic effects of bevacizumab (Avastin), pegaptanib (Macugen), and verteporfin photodynamic therapy (PDT), using novel OCT parameters, in a recently completed phase III/IV clinical trial. Methods: Data from 122 patients participating in the Avastin (Bevacizumab) for Choroidal neovascularization (ABC) trial, were evaluated. Stratus OCT images were analyzed using custom software - changes in volume of the neurosensory retina, subretinal fluid (SRF), pigment epithelium detachment (PED), and ...

      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 ...

      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 ...

      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 ...

      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.
