Ophthalmologic Techniques That Evaluate the Posterior Segment for Glaucoma

Analysis of the optic nerve and retinal nerve fiber layer in the diagnosis and evaluation of patients with glaucoma or glaucoma suspects may be considered medically necessary when using scanning laser ophthalmoscopy, scanning laser polarimetry, and optical coherence tomography.

The measurement of ocular blood flow, pulsatile ocular blood flow, or blood flow velocity is considered investigational in the diagnosis and follow-up of patients with glaucoma.
