Ophthalmologic Techniques For Evaluating Glaucoma

This policy covers ophthalmologic imaging and functional techniques for evaluating glaucoma — including OCT, scanning laser ophthalmoscopy, confocal scanning laser imaging, scanning laser polarimetry and RNFL thickness measurement, as well as specialized ocular blood‑flow assessments — for diagnosis and monitoring of glaucoma and glaucoma suspects. It applies to patients with suspected or established glaucoma (including primary open‑angle, normal‑tension, and angle‑closure glaucoma) and for progression monitoring but requires a comprehensive ophthalmologic examination (no single test suffices); many ocular blood‑flow measurements and ≥24‑hour IOP monitoring (e.g., contact‑lens sensors) are considered experimental/investigational, OCT generally requires pharmacologic pupil dilation, and RNFL thickness measurements have investigational/limited clinical utility.
