Encyclopedia entry (1928–1936)
BRUCH'S MEMBRANE (Bruch), the posterior limiting lamina of the iris. According to the majority of authors, Bruch's membrane represents a contractile lamina — membrana dilatatrix iridis. On a meridional section of the iris, it appears as a thin, light, slightly striated layer adjacent to the pigment layer. Bruch's membrane is formed from the contractile processes of cells whose pigmented bodies with nuclei lie posteriorly and, together with the pars iridica retinae, form a single common layer of pigmented cells. — Lit.: see Eye.
