Insertion of the dorsal oblique muscle in the dog: an anatomic basis for ventral strabismus associated with oculomotor nerve dysfunction.

Objective: To describe the insertion of the dorsal oblique (DO) muscle in relationship to the equator of the globe in dogs.

Procedure: The study was conducted on 10 fresh cadaver eyes from five dogs, which were euthanized for disease processes unrelated to ocular disease. A manual vernier caliper was used to determine the calculated measurements.
