Iris atrophy
Also known as: Irisatrophie · Senile Irisatrophie · Atrophia iridis · Iris degeneration · Pupillary margin atrophy
Overview
What it is
Iris atrophy is a progressive thinning and degeneration of the iris, which is the colored part of the eye that controls how much light enters. This condition affects the muscular structure of the eye, causing the pupil to lose its ability to shrink fully in bright light. It is typically a natural part of the aging process and does not cause pain.
How it presents
Owners of senior dogs may notice irregularly shaped pupils, visible holes in the colored part of the eye, or pupils that remain unusually dilated. This can make the dog sensitive to bright light, leading to squinting in sunny environments.
Treatment
The condition is incurable but generally harmless, requiring no active treatment. Periodic veterinary monitoring to rule out secondary issues typically costs between 150 and 600 EUR.
