What complication may arise unique to Golden Retriever pigmentary uveitis?

The correct answer highlights the unique complication of obstructive glaucoma associated with pigmentary uveitis in Golden Retrievers. Pigmentary uveitis is a condition characterized by inflammation within the eye, leading to the accumulation of pigment in the anterior chamber and possibly the retina. Over time, this can obstruct the normal outflow of aqueous humor, resulting in increased intraocular pressure.

In Golden Retrievers specifically, obstructive glaucoma can occur as a direct consequence of the pigmentary changes that arise from this type of uveitis. The blockage of the drainage angle due to pigment and debris can lead to significant ocular complications, including pain and vision loss, if not managed properly.

While chronic conjunctivitis, corneal ulcers, and retinal hemorrhage can be seen in various ocular conditions, they are not specifically tied to the process and progression of pigmentary uveitis in the Golden Retriever breed. As such, obstructive glaucoma is the complication most closely associated with this condition due to the pathological changes that occur in the eye. Understanding this connection emphasizes the importance of monitoring and managing intraocular pressure in affected individuals to prevent debilitating outcomes.
