Answer

Optical coherence tomography (OCT) appears to be a better tool in discovering retinal abnormalities before they appear on ophthalmologic examination. In a study of patients with neurosarcoidosis, 75% demonstrated quantitative OCT abnormalities, compared with 25% who had detectable abnormalities on detailed ophthalmological assessment. In the same study, 33% of patients with no ophthalmologic symptoms showed detectable abnormalities on OCT, compared with 8% of such patients who had abnormalities upon ophthalmologic examination.
