    The demise of direct ophthalmoscopy: A modern clinical challenge
    (Ovid Technologies (Wolters Kluwer) - American Academy of Neurology, 2015-04) Mackay, Devin D.; Garza, Philip S.; Bruce, Beau B.; Newman, Nancy J.; Biousse, Valérie; Department of Neurology, IU School of Medicine
    Ocular funduscopy appears to be a dying art. Physicians and medical students alike lack confidence in the use of an ophthalmoscope. As a result, few clinicians perform ophthalmoscopy, and many who do are unable to reliably detect abnormalities of the ocular fundus. Approaches to remediation in undergraduate medical education have included simulators, longitudinal skill reinforcement, Web-based teaching, and other techniques. Preservation of the ophthalmoscopic art has been hindered by technical difficulty, waning enthusiasm for ophthalmoscopy, and even discouragement from preceptors in medical education. Ocular fundus photography may serve a role in medical education to help improve student confidence in interpretation of ocular fundus findings and improve awareness of the importance of examination of the ocular fundus. Because neurology clerkships and clinical practices remain an important forum for honing ocular funduscopy skills, the neurologist should be familiar with novel alternative techniques that facilitate examination of the ocular fundus.

    Nonmydriatic Fundus Photography: A Practical Review for the Neurologist
    (BMJ, 2016-10) Mackay, Devin D.; Bruce, Beau B.; Department of Neurology, IU School of Medicine
    Declining proficiency in direct ophthalmoscopy by non-ophthalmologists has spurred a search for alternative methods of ocular fundus examination. Recent technological advances have improved the ease of use and quality of non-mydriatic fundus photography, increasing its suitability for clinical care. As the availability of this technology continues to improve, neurologists will need to be familiar with its advantages, limitations and potential applications in the clinical care of patients with neurological conditions.

    Referral Patterns in Neuro-Ophthalmology
    (Wolters Kluwer, 2020-12) Stunkel, Leanne; Mackay, Devin D.; Bruce, Beau B.; Newman, Nancy J.; Biousse, Valérie; Neurology, School of Medicine
    Background: Neuro-ophthalmologists specialize in complex, urgent, vision- and life-threatening problems, diagnostic dilemmas, and management of complex work-ups. Access is currently limited by the relatively small number of neuro-ophthalmologists, and consequently, patients may be affected by incorrect or delayed diagnosis. The objective of this study is to analyze referral patterns to neuro-ophthalmologists, characterize rates of misdiagnoses and delayed diagnoses in patients ultimately referred, and delineate outcomes after neuro-ophthalmologic evaluation. Methods: Retrospective chart review of 300 new patients seen over 45 randomly chosen days between June 2011 and June 2015 in one tertiary care neuro-ophthalmology clinic. Demographics, distance traveled, time between onset and neuro-ophthalmology consultation (NOC), time between appointment request and NOC, number and types of providers seen before referral, unnecessary tests before referral, referral diagnoses, final diagnoses, and impact of the NOC on outcome were collected. Results: Patients traveled a median of 36.5 miles (interquartile range [IQR]: 20–85). Median time from symptom onset was 210 days (IQR: 70–1,100). Median time from referral to NOC was 34 days (IQR: 7–86), with peaks at one week (urgent requests) and 13 weeks (routine requests). Median number of previous providers seen was 2 (IQR: 2–4; range:0–10), and 102 patients (34%) had seen multiple providers within the same specialty before referral. Patients were most commonly referred for NOC by ophthalmologists (41% of referrals). Eighty-one percent (242/300) of referrals to neuro-ophthalmology were appropriate referrals. Of the 300 patients referred, 247 (82%) were complex or very complex; 119 (40%) were misdiagnosed; 147 (49%) were at least partially misdiagnosed; and 22 (7%) had unknown diagnoses. Women were more likely to be at least partially misdiagnosed—108 of 188 (57%) vs 39 of 112 (35%) of men (P < 0.001). Mismanagement or delay in care occurred in 85 (28%), unnecessary tests in 56 (19%), unnecessary consultations in 64 (22%), and imaging misinterpretation in 16 (5%). Neuro-ophthalmologists played a major role in directing treatment, such as preserving vision, preventing life-threatening complications, or avoiding harmful treatment in 62 (21%) patients. Conclusions: Most referrals to neuro-ophthalmologists are appropriate, but many are delayed. Misdiagnosis before referral is common. Neuro-ophthalmologists often prevent vision- and life-threatening complications.
