The scleral spur in the visual system is a protrusion of the sclera (the white of the eye) into the anterior chamber. The spur is an annular structure composed of collagen in the human eye.

2017年11月8日 · Scleral Spur. The scleral spur is composed of a ring of collagen fibers that run parallel to the limbus. It marks the posterior border of the trabecular meshwork. The spur projects slightly into the anterior chamber and is seen as a white to yellowish line in most eyes.

Scleral spur location represents an important anatomical landmark in imaging the anterior chamber angle, as it is a reference point for the relative position of the trabecular meshwork.

2021年4月8日 · Scleral spur: The scleral spur is composed of a band of collagen fibers that run parallel to the limbus. It marks the posterior border of the trabecular meshwork and projects slightly into the anterior chamber, and is seen as a white-yellowish line in most eyes. 2,5,6 The longitudinal muscle of the ciliary body attaches to the scleral spur and ...

The scleral spur is a fibrous ring that, on meridional section, appears as a wedge projecting from the inner aspect of the anterior sclera (Figs 3-1 and 3-2). The spur is attached anteriorly to the trabecular meshwork and posteriorly to the sclera and …

Scleral Spur. The scleral spur is comprised of a ridge of collagen tissue and appears white on gonioscopy. Identifying this structure helps to differentiate open angles from closed angles. It is possible for the scleral spur to be covered by small sharp-ended iris processes that reach up to the trabecular meshwork.

At its anterior boundary the sclera merges with the corneal perimeter at the limbus and extends backward to form an approximate sphere of vertical diameter ~24mm. The axial length of the emmetropic adult human eye is 24–25mm.

2009年7月15日 · The scleral spur is the next normal angle structure. It is the site of attachment of the longitudinal muscle of the ciliary body and is the anterior extension of the sclera. The scleral spur appears as a narrow, white band and is relatively consistent between patients.

2017年11月8日 · The scleral spur is a ridge of scleral tissue that lies anterior to the ciliary body band and marks the posterior border of the trabecular meshwork. It appears as a thin band that is usually white or light gray (5‑5) but which may have a yellowish cast in older individuals (5‑6).

The scleral spur is an anular elevation in the anterior chamber, composed of the trabecular tissue opening toward the sclera venous sinus and that encloses the posterior portion of this sinus.
