OCTA visualizes and quantifies FAZ enlargement, capillary non-perfusion and vessel density in diabetic eyes.
How does OCTA change patient care?
OCTA helps doctors understand the extent of damage caused by diabetic eye disease to guide management decisions.
OCTA images provide an excellent tool for educating patients on the importance of controlling their disease and may be used to improve communication with other care providers.
43-year-old African-American male presented for a comprehensive eye examination
12-year history of poorly controlled diabetes
BCVA 20/30 OU
Anterior segment biomicroscopy unremarkable
Vascular alterations consistent with hypertension in both eyes
Moderate non-proliferative diabetic retinopathy as indicated by variable dot and blot hemorrhages throughout most of the posterior pole
Drusen visible bilaterally (FIGURE 1)
OCTA showed intraretinal hemorrhages without evidence of macular edema (FIGURE 2)
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).
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.
