Krukenberg's spindle

A more or less vertical spindle-shaped deposition of brownish pigment on the corneal endothelium. It is often accompanied by pigment deposits on the lens, zonule, anterior surface of the iris and trabecular meshwork and may form part of the pigment dispersion syndrome. The pigment comes from the iris pigment epithelium, but the cause of its shedding is not established and may be strenuous exercise, mechanical rubbing by the zonules due to posterior bowing of part of the iris or degenerated pigment. It occurs in young to middle-aged myopic individuals and sometimes following uveitis.
