RAO testing: Which of the following is NOT listed as part of RAO testing?

• A. IV Fluorescein Angiography
• B. Gonioscopy
• C. ESR/CRP/CBC
• D. Optical Coherence Tomography

Answer: (D)

This item tests which diagnostic elements are included in the RAO testing set. In this context, RAO testing comprises imaging of retinal vasculature and inflammation status: intravenous fluorescein angiography to assess retinal blood flow and leakage, gonioscopy to evaluate the anterior chamber angle, and basic systemic labs such as ESR, CRP, and CBC to screen for inflammatory or systemic processes that can relate to ocular disease. Optical Coherence Tomography, while an excellent tool for detailed retinal layer imaging and glaucoma evaluation, is not listed among the RAO testing components in this scenario. It remains a valuable clinical instrument for structural retinal assessment, but it isn’t part of the RAO test lineup described here.
