Diagnosing and Treating Avian Neurologic Disease

The cranial nerve exam differs little from that of mammals, however there are differences in innervation. As in mammals, menace and pupillary light response (PLR) require use of cranial nerves II (optic) and III (oculomotor), however menace is difficult to interpret in birds. Also, PLR may be overridden in birds due to the presence of striated iridal muscle. Evaluate PLR early in the exam using a sudden, bright light directed toward the medial canthus. Consensual PLR is absent due to…

Arterial blood pressure measurement is an important tool in the management of the critically ill bird.

Although direct arterial pressure measurement is ideal, it is not commonly used because of the need for specific technical skill, invasive nature of the procedure, and cost of equipment.

As in mammals, oxygen therapy is potentially toxic if given for prolonged periods at high levels.
