Krukenberg's spindle is the name given to the pattern formed on the inner surface of the cornea by pigmented iris cells that are shed during the mechanical rubbing of posterior pigment layer of the iris with the zonules that are deposited as a result of the currents of the aqueous humor.

Jan 1, 2009 · When liberated pigment accumulates in the trabecular meshwork and limits aqueous humor outflow, increased intraocular pressure and pigmentary glaucoma may develop. Often the first sign of PDS, a Krukenberg spindle represents the vertical collection of pigment granules along the corneal endothelium.

Krukenberg spindle runs the course of being mild pigment dispersion syndrome to a condition known as pigmentary glaucoma where the loose pigment in the eye can plug up the drainage system leading to high intra-ocular pressure and optic nerve damage.

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 ...

Krukenberg’s spindle (KS) formation is well-known to occur in association with “classic” or primary pigment dispersion syndrome (PDS) and pigmentary glaucoma (PG), and there has been discussion of this important clinical finding over many decades. 1 – 8 Although the attention that KS formation has received in conjunction with classic ...

Pigment dispersion syndrome (PDS) is characterized by dispersion of pigment in the anterior chamber structures and can present with deposits on the central corneal endothelium or Krukenberg spindle, iris trans-illumination spoke-like defects, and increased pigmentation in the iridocorneal angle.

The Krukenberg's spindle presence is strongly associated with the LAZ trait and is an indicator of LAZ-associated pigment dispersion. In people who exhibit KS formation, the LAZ trait should be searched for, especially in those who have other characteristics that are highly associated with LAZ, including age over 50 years and hyperopia.

The classic findings, “Classic Triad”, of the anterior segment include pigment deposition in the corneal endothelium (Krukenberg spindle), dense pigmentation of the trabecular meshwork (TM) and transillumination defects of the iris in the midperiphery. 1,2 A characteristic concave iris configuration has also been described to facilitate ...
