Neuro-Ophthalmic Disease Cases
Kelly A. Malloy, OD, FAAO, Diplomate
Clinical cases will be used to demonstrate the varied presentations related to neuro-ophthalmic
disease. These will include both afferent and efferent manifestations of neuro-ophthalmic
disease, as well as associated ocular health and neurologic manifestations. Conditions that may
be demonstrated through clinical cases are included in the outline below.
Course Learning Objectives:
1. To emphasize the importance of the optometrist’s role in identifying signs and
symptoms which suggest a neuro-ophthalmic disease process.
2. To understand how to conduct an examination oriented to the detection of neuro-ophthalmic
disease.
3. To discern the differential diagnoses for a variety of clinical neuro-ophthalmic presentations.
4. To become familiar with the necessary diagnostic testing for a variety of neuro-ophthalmic
presentaions.
5. To emphasize the need to promptly identify and refer patients presenting with
emergent neuro-ophthalmic disease conditions.
6. To have a better understanding of the work-up, management, and treatment of
neuro-ophthalmic disease conditions.
Neuro – Ophthalmic Disease Cases - OUTLINE
Conditions that may be demonstrated through actual clinical cases are included in the outline
below.
