This visual impairment case takes place in Pennsylvania and involves a male patient who suffered episodes of nausea and vomiting over the course of several months. On one occasion, the patient presented to the hospital with nausea, vomiting, abdominal pain, and a range of other gastrointestinal symptoms. He was given over the counter nausea medication by the ER physician and was sent home. Over the next few days, the patient’s symptoms became progressively worse, and the patient returned to the same hospital ER. He presented to the ER with cold and numbness in arms, as well as significant weight loss, in addition to his original symptoms. Despite the increasing severity of his symptoms he was discharged a few days later. Some time after being discharged from the hospital, the patient developed severe eye pain and blurry vision. He was seen by ophthalmology then and was diagnosed with bacterial conjunctivitis, and prescribed Moxifloxacin eye drops. A few days after this diagnosis, the patient lost all vision in both eyes. He presented to the ER and received treatment, however his condition did not improve. Eventually, he was diagnosed with a rare, but treatable, autoimmune disease.
