CPT® Code 65820

The procedure described by CPT® Code 65820 refers to a goniotomy, which is a surgical intervention primarily aimed at treating congenital glaucoma in pediatric patients. Congenital glaucoma is a condition characterized by an abnormal increase in intraocular pressure due to developmental issues affecting the eye's drainage system. Specifically, this condition can lead to developmental arrest of the iris and ciliary body, which obstructs the trabecular network. This obstruction hinders the proper drainage of aqueous humor, resulting in elevated intraocular pressure that can damage the optic nerve and impair vision. During a goniotomy, the physician employs a series of precise steps to create an opening in the trabecular meshwork, thereby facilitating improved drainage of aqueous fluid. The procedure involves the administration of mitotic eye drops to constrict the pupil, stabilization of the eye, puncturing of the cornea, and the introduction of a viscoelastic tube to assist in fluid management. The use of a gonioscopy lens allows for direct visualization of the anterior trabecular meshwork, which is then incised to restore normal fluid dynamics within the eye. This surgical approach is critical for preventing further complications associated with congenital glaucoma and preserving the visual function of affected children.
