Sahar Bedrood, MD, PhD, joins Sila Bal, MD, MPH, to present a case of a 45-year-old woman who came to the emergency room reporting headache, nausea, blurred vision, and rainbow halos. Upon initial examination the patient’s visual acuity was 20/100 and had an acutely elevated IOP of 51 mm Hg OD. Dr. Bedrood discusses how she initially approached this patient and stresses the value of obtaining a detailed medical history. She outlines her examination and treatment process and shares insight into how she might have managed this patient with earlier intervention.
