Iris hypoplasia
Also known as: Iris-Hypoplasie · Congenital iris hypoplasia · Hypoplasia iridis · Iris-Unterentwicklung
Overview
What it is
Iris hypoplasia is a congenital condition affecting the eye where the iris, which is the colored part of the eye, is underdeveloped and thinner than normal. This thinning or the presence of small gaps means the eye cannot fully regulate the amount of light entering the pupil. It is a benign, non-painful developmental variation rather than an active, progressive disease.
How it presents
Symptoms are present from puppyhood and typically manifest as irregularly shaped pupils that do not fully constrict in bright light. Owners might also notice mild squinting or light sensitivity when the dog is outdoors in direct sunlight.
Treatment
This is a benign condition that requires no clinical treatment or active therapy. No medical intervention is necessary, keeping lifetime costs between 0 and 100 EUR, which would only cover optional, routine veterinary eye checks.
