Spectral domain optical coherence tomography (SD-OCT) assessment of the healthy female canine retina and optic nerve.

Objective: To provide normative data for canine whole retinal thickness (WRT), nerve fiber layer thickness (NFL), photoreceptor layer thickness (PR), and outer nuclear layer thickness (ONL) using spectral domain optical coherence tomography.

Animal Studied: Twelve healthy adult intact female beagles.

Procedure: Horizontal volume scans through the area dorso-temporal from the optic nerve (superior retina), and the area ventro-temporal from the optic nerve (inferior retina) were used to evaluate the thickness of retinal NFL, PR, ONL, and WRT.
