Fig. 6. Scanning electron micrograph (24×) of a human vascular cast of the anterior plexuses of the eye. The anterior ciliary arteries (ACA) form the anterior episcleral arterial circle which gives rise to limbal arcades, anterior conjunctival plexus, superficial episcleral plexus (SE) and deep episcleral plexus (DE). Note the interconnections between superficial episcleral plexus and deep episcleral plexus (arrows). (Courtesy of Dr. AW Fryczkowski.)
