Which imaging modalities are used for CSR testing?

• A. Mac-OCT, IVFA
• B. Fundus photography and red-free imaging
• C. OCT and B-scan only
• D. Visual field testing

Answer: (A)

In CSR testing, you want both detailed macular structure and evidence of leakage. Mac-OCT provides high-resolution cross-sectional images of the macula, showing subretinal fluid and neurosensory retinal detachment typical of central serous retinopathy. Intravenous fluorescein angiography (IVFA) reveals dynamic leakage patterns from the choroid through the retinal pigment epithelium, helping localize the leak source and confirm CSR. Other imaging options fall short because they document appearance or function without showing the critical leakage information. Fundus photography and red-free imaging can illustrate the detachment but don’t reveal leakage dynamics. OCT with B-scan adds structural detail but lacks the vascular leakage data. Visual field testing assesses function rather than imaging the macula or leakage. Therefore, combining Mac-OCT with IVFA gives the most comprehensive CSR assessment.
