Diabetic retinopathy (DR) is a major cause of vision loss in diabetes, but diagnosis is often delayed due to asymptomatic early stages. They highlight that RBP3 is secreted exclusively by photoreceptors and its levels inversely correlate with DR progression. The review discusses two-photon excitation fluorescence (TPEF) as a promising imaging modality to quantify RBP3 in vivo, leveraging its deep tissue penetration and low photodamage using infrared light. The authors argue that this functional imaging approach could provide a quantifiable, objective measure of DR status before clinical signs appear, potentially guiding early intervention. The central limitation is that the proposed method is conceptual and requires significant development and validation. The review synthesizes preclinical and human observational data to support RBP3's role in DR pathogenesis, but does not present new experimental findings.
