Which test is listed as part of POAG testing?

• A. RNFL/GCC OCT
• B. Fluorescein angiography
• C. CT scan
• D. Ultrasound

Answer: (A)

Assessing POAG relies on identifying structural damage to the optic nerve and retinal ganglion cells. Optical coherence tomography that targets the retinal nerve fiber layer and the macular ganglion cell complex provides quantitative thickness measurements of these structures. In glaucoma, RNFL thinning and GCC thinning reflect loss of ganglion cells, often correlating with disease stage and progression, making RNFL/GCC OCT a central tool in both diagnosis and monitoring. Fluorescein angiography maps retinal circulation and is used for vascular retinal diseases rather than glaucomatous damage, so it’s not part of POAG testing. CT scans and ultrasound image anatomy differently and aren’t routine for assessing glaucomatous nerve damage; they aren’t sensitive to RNFL or GCC changes and aren’t used to guide glaucoma management. In practice, RNFL/GCC OCT is paired with functional testing like visual field assessment and IOP measurement to provide a comprehensive POAG evaluation.
