This report demonstrates the structural retinal changes observed in-vivo by spectral domain optical coherent tomography (SD-OCT) in a case of isolated cilioretinal artery occlusion. A 32-year-old woman presented one week following acute sudden painless loss of vision. Ophthalmoscopy revealed macular edema and a cherry red spot. Fluorescein angiography one week post-infarction demonstrated a large patch of macular hypoflorescence in the distribution of the cilioretinal artery, with perfusion of the cilioretinal artery. Within this same macular distribution, SD-OCT demonstrated increased reflectivity, with increased reflectivity of the inner nuclear, inner plexiform, and ganglion cell layers. A sharp boundary was present between normal and infarcted macula on SD-OCT imaging. SD-OCT is a useful tool for diagnosing and identifying the extent of retinal vascular occlusion.
