Fig. 1.

A ruptured retinal arterial macroaneurysm (RAM) was detected in the left eye of a 78-year-old-female. Color fundus photography and optical coherence tomography (OCT) show retinal and subretinal hemorrhage and serous retinal detachment around the RAM (A, B, and F) (arrow indicates the RAM in OCT). OCT (OCT-A1, Canon) shows blood flow signal within the RAM lesion (C and G). Offset pinhole adaptive optics scanning light ophthalmoscope shows pulsation and extreme thinning of the affected arterial wall with high resolution (D-E, and Video 1).
