macula lutea in dogs

An oval area in the retina, usually located temporal to the posterior pole of the eye and slightly below the level of the optic disk. It is characterized by the presence of a yellow pigment diffusely permeating the inner layers, contains the fovea centralis in its center, and provides the best phototopic visual acuity. It is devoid of retinal blood vessels, except in its periphery, and receives nourishment from the choriocapillaris of the choroid. (From Cline et al., Dictionary of Visual Science, 4th ed). Every claim on this page comes from the Leumas anatomy graph and carries its source.

The atlas records it as a organ at the organ scale in the dog.

Where the macula lutea is

It sits in the head, within the nervous and sensory systems. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.

What the macula lutea connects to

The atlas records 4 typed relationships for it, across 3 kinds of connection. part of organ and retina.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the macula lutea. Only a minority of structures carry those edges here, so an empty answer means nothing has been recorded — not that there is nothing to record.

Also called

Also recorded as macula, macula flava retinae, macula retinae and maculae. Searching any of those names reaches this page.

Is the macula lutea the same in other species?

This page describes the dog. The human record of the same structure sits beside it on /compare, over one shared model rather than two atlases built separately.
