The most precise diagnostic tool of RPE has been OCT (optical coherence tomography) for some 19 years. This chapter gives an overview of the OCT technique and its possibilities, technical development and limits. A systematic overview of SD-OCT in healthy and diseased RPE is given.

SD-OCT in Pigmented Paravenous Retinochoroidal Atrophy
Ophthalmic Surgery, Lasers and Imaging Retina, 2012Pigmented paravenous retinochoroidal atrophy (PPRCA) is a rare disease characterized by bilateral retinochoroidal atrophy and pigmentation along the retinal veins. The authors describe spectral-domain optical coherence tomography (SD-OCT) in a case of PPRCA. The right macula showed a lamellar macular hole.

SD-OCT and autofluorescence characteristics of autoimmune retinopathy
British Journal of Ophthalmology, 2012To report abnormal fundus hyperautofluorescence (hyper-AF) and loss of outer retinal layers by spectral domain optical coherence tomography in patients with autoimmune retinopathy (AIR).Retrospective, observational case series of 14 eyes of 7 patients diagnosed with an AIR for whom colour fundus photographs, fundus AF images and spectral domain optical

SD-OCT to distinguish papilledema from pseudopapilledema
Archivos de la Sociedad Española de Oftalmología (English Edition), 2015Two patients presented with headache and bilateral papillary edema. Patient 1 was found to have a papilledema (P) with intracranial pressure of 32cmH2O. Patient 2 was found to have a migraine with a pseudopapilledema (PP) (optic nerve head drusen). SD-OCT was used to image the optic disc, subretinal hyporeflective space (SHS), and alpha-angle (Aα).Optic

Drusen in adaptive optics and SD‐OCT
Acta Ophthalmologica, 2009Abstract Purpose The study objective was to explore the microscopic structure of soft macular drusen and surrounding retinal areas using an adaptive optics (AO) camera and to compare the findings to those from standard clinical examinations. Methods 18 patients of age between 65 and 85 and presenting soft macular drusen were recruited after aninitial ...

Abstract Purpose Optical coherence tomography (OCT) has emerged as a leading technique in ophthalmic imaging due to its capability to non‐invasively resolve tissue morphology with high sensitivity and high axial resolution. Despite increases in axial resolution, monochromatic ocular aberrations limited the transverse resolution for retinal imaging to ...

Clinical Significance of B-Scan Averaging With SD-OCT
Ophthalmic Surgery, Lasers and Imaging Retina, 2012Averaging multiple scans is a potential advantage of optical coherence tomography. The authors evaluate the qualitative benefits of B-scan averaging on the visualization of outer retinal structures. A retrospective analysis was performed on Cirrus OCT (Carl Zeiss Meditec, Dublin, CA) B-scans from 1 eye of 35 patients referred to the ...
