Anatomy of the anterior chamber and angle
The document summarizes the anatomy of the anterior chamber angle. It describes the key structures within the angle including the iris, trabecular meshwork, scleral spur, Schwalbe's line, and ciliary body band. It provides details on the composition, function, and innervation of each structure. Gonioscopy grading is also briefly mentioned.

- 16. Ciliary Body Band •Posteriormost part of the angle. •Represents the anterior face of ciliary body between its attachment to the scleral spur and insertion of iris. • Width depends on the level of iris insertion. •Dark brown band
- 17. INNERVATION: • Derives fromthe supraciliary nerve plexus and the ciliary plexus in the region of scleral spur. • Both sympathetic adrenergic and parasympathetic and sensory innervation .
