Purpose: To define the morphology of outer choroidal margins in swept source optical coherence tomography (SS-OCT).

Methods: Prospective observational study of 180 eyes: 20 eyes of healthy volunteers, 20 eyes of myopic patients and 20 eyes from each of the following groups: macular hole (before and after surgery), lamellar macular hole, epiretinal membranes, drusen, dry age related macular degeneration, neovascular age related macular degeneration, vitreomacular traction.

Results: SCS was observed in 5% of healthy eyes, half of the eyes with full thickness macular holes and in 60% of eyes with vitreomacular traction syndrome. It was also present in half of the eyes with dry age related macular degeneration and in 20% of eyes with neovascular AMD.

Conclusions: SS-OCT uses a longer wavelength than conventional OCT devices, which enables exact visualization of the outer choroidal margin. This enabled visualization of the suprachoroidal space in vivo in eyes without choroidal effusion. This may add information to existing knowledge of the pathogenesis and natural course of specific macular diseases.
