Fig. 24. A. Photograph of the peripheral retina, demonstrating several small fibroglial membranes. B. Fluorescein angiogram corresponding to A, showing multiple arteriolar-venular anastomoses with early sea fan formation. C. Photograph of the same area 2 years later demonstrates more fibroglial membranes. D. Fluorescein angiogram corresponding to C shows new sea fans caused by an arteriolar-venular anastomosis (curved arrow). Large arrow (A through D) identifies corresponding arteriolar bifurcation.
