Systematic Assessment of Clinical Methods to Diagnose and Monitor Diabetic Retinal Neuropathy

Figure 4

Number of studies of pre- and early diabetic retinopathy-detecting imaging modalities sorted by relative strength of evidence. OCT rather surprisingly does not have a strong base of compelling evidence for diabetic retinal neuropathy. The results for retinopathy detection software, digital fundus photography, and retinal image processing are ample, but problematic at this stage of inquiry into diabetic retinal neuropathy.
