A.Yellowish drainage and photophobia B.Mild itching and bloodshot appearance C.Pain early after surgery accompanied by nausea and vomiting D.Change in visual acuity accompanied by tearing and redness b Mild itching and bloodshot appearance are considered to be normal postoperative outcomes for this patient. Pain early after surgery may indicate increased intraocular pressure or hemorrhage. Change in visual acuity accompanied by tearing and redness and any yellowish drainage and photophobia can be signs of infection.

A 78-year-old patient tells the nurse that over the past 18 months he has noticed a decrease in visual acuity in his left eye. He states that he initially thought he had smudges on his eyeglasses, but when the cloudiness in his vision continued to develop, he saw his doctor who referred him to an ophthalmologist.
