A 52-year-old man presented to the emergency department (ED) for left frontotemporal headache and left eye pain. In the ED, visual exam with extra-ocular movement was performed to rule out ocular pathology and brain imaging to rule out cerebral pathology. No abnormal finding was noted after evaluation of ED. Initial exam by an ophthalmologist was also negative with normal intraocular pressure. Left lens dislocation was found only after brain imaging. In subsequent second exam by an ophthalmologist with iridodilator, lens dislocation due to spontaneous zonulysis was finally confirmed. Hence, ED physicians should carefully review ocular as well as brain anatomy in such cases.
