Chorioretinal anastomosis in adaptive optic and high definition spectral domain optical coherence tomography

Purpose To assess morphologic variations in the outer and inner retinal layers in eyes with chorioretinal anatomosis using high definition Spectral Domain Optical Coherence Tomography (Spectralis HRA OCT, Heidelberg Engineering, Heidelberg, Germany) and to compare these scans with images acquired by Adaptive Optics (AO). Methods This was a prospective observational case series including 50 patients. SD-OCT scans were obtained with combined confocal scanning laser ophthalmoscope (cSLO) and SD-OCT for simultaneous tomographic and topographic in vivo imaging. Patients underwent fluorescein and ICG- angiography and Adaptive Optics assessment with Imagine Eyes™ System. The neurosensory retina and the photoreceptor layer were analyzed using both HR-OCT and AO imaging. Results Combining of the adaptive optics with SD-OCT may give us further information of the early stage development of chorioretinal anastomosis.
