Carotid Artery Endarterectomy Effect on Choroidal Thickness: One-Year Follow-Up

Figure 3

Patient #7: a 75-year-old male, with a past medical history of hypertension, CVA, CAD, hypercholesterolemia, and smoking (40 pack-years), presented with right ICA stenosis of 90%. His BCVA at presentation was RE 6/7.5 and LE 6/7.5. Moderate nuclear sclerosis was present in both eyes with no pathological findings in the funduscopy of both eyes. He underwent an uneventful CEA, and on follow-up, there was no right ICA stenosis at all. EDI SD-OCT images of the RE, with choroidal thickness measurements (subfoveal; 500 µm, 1000 µm, and 1500 µm nasal and temporal), obtained one day before right CEA (a) and 14 months after CEA (b). CVA: cerebrovascular accident; CAD: coronary artery disease; ICA: internal carotid artery; BCVA: best-corrected visual acuity; RE: right eye; LE: left eye; CEA: carotid artery endarterectomy; EDI: enhanced depth imaging; SD-OCT: spectral domain optical coherence tomography.
