Resolved incomplete central retinal-artery obstruction simulating ischemic optic neuropathy.

To our knowledge, this is the first reported case of an embolic three-fourths central retinal-artery obstruction with isolated sparing of the superior temporal branch artery. Multiple nonfoveolar-sparing cilioretinal arteries were also present. As a result of the unusual obstruction distribution, ischemic optic neuropathy was simulated after a five-month interval. Patients who are not seen acutely after a retinal-artery obstruction may be diagnosed and managed incorrectly if this variation from the usual condition is not recognized.
