Funduscopy exams now done infrequently
A Loyola University Medical Center study published in the journal Frontiers in Neurology has found that direct funduscopy exams are being performed infrequently. Researchers who examined patient records found that it was used during the initial evaluation on only 26% of patients with primary visual symptoms, 25% of patients with headaches, and 5% of patients with altered mental status.
