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

Figure 2

Patient #1: a 61-year-old male, with a past medical history of hypertension, hypercholesterolemia, TIA, and smoking (40 pack-years), presented with right ICA stenosis of 80%. His BCVA at presentation was RE 6/6.5 and LE 6/7.5. Mild nuclear sclerosis was present in both eyes with no pathological findings when performing fundoscopy 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 6 months after CEA (b). TIA: transient ischemic attack; 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.
