Review Question - QID 212371

A 78-year-old woman presents to the ophthalmologist with complaints of painless, blurry vision that has worsened in the past year. She says that she sees halos around lights and that she particularly has trouble driving at night because of the glare from headlights. Her temperature is 98.7°F (37°C), blood pressure is 138/91 mmHg, pulse is 68/min, respirations are 14/min, and oxygen saturation is 98% on room air. On physical exam, the patient has an absence of a red reflex. What is the most likely pathology that is causing this patient’s visual symptoms?
