CLINICAL FINDINGS

OCTA ASSESSMENT

OCTA Assessment showed extensive enlargement of the FAZ with capillary non-perfusion. Truncated, telangiectatic vessels and microaneurysms were visible in areas of non-perfusion (FIGURE 3). The vessel density maps of the superficial capillary plexus demonstrated diffuse ischemia (FIGURE 4).

CONCLUSION

This patient demonstrated evidence of moderate non-proliferative retinopathy without macular edema on clinical examination. However, his B-scans were quite unremarkable and did not well correlate with the duration of disease or the retinal findings. OCTA displayed the retinal vasculature in precise detail providing supplemental information that was critical in the decision making process for this patient, as stricter blood sugar control and adherence to a diabetic regimen is crucial.
