Anterior segment dysgenesis(ASD)
Also known as: Anterior Segment Dysgenesis of the eye · Congenital anterior segment anomalies · Vorderkammerdysgenesie · Dysgenese des vorderen Augenabschnitts · Peters' anomaly · …
Overview
What it is
Anterior segment dysgenesis is an inherited eye condition where the front structures of the eye, including the clear outer cornea, the colored iris, and the lens, fail to develop properly before birth. This abnormal development can block the natural drainage pathways of the fluid inside the eye. When this fluid cannot drain, pressure builds up within the eyeball, which can damage the dog's vision.
How it presents
Symptoms typically become visible during puppyhood, presenting as cloudy or hazy eyes, pupils with irregular shapes, or signs of vision loss. Over time, the pressure buildup often leads to glaucoma, which causes the eyes to look red, swollen, and painful.
Treatment
The condition is not curable, but the resulting high eye pressure requires lifelong management using daily prescription eye drops or surgery. Lifetime treatment and specialized veterinary care typically cost between €1,500 and €6,000.
