Low Limit for Effective Signal Strength in the Stratus OCT in Imperative Low Signal Strength Cases [PDF]
Korean Journal of Ophthalmology, 2012 To determine the lowest limit of signal strength that is still effective for accurate analysis of optic coherence tomography (OCT) values, we investigated the reproducibility of OCT scans by signal strength (SS).A total of 668 subjects were scanned for measurements of retinal nerve fiber layer (RNFL) thickness using the Stratus OCT twice on the same ...
