Ocular melanosis(OM)
Also known as: Cairn Terrier ocular melanosis · Pigmentary glaucoma · Melanosis ocularis · Oculäre Melanose · Pigmentglaukom
Overview
What it is
Ocular melanosis is an inherited eye condition where pigment-producing cells multiply abnormally within the eye. These dark pigment deposits can block the natural drainage pathways for eye fluid. This blockage leads to a dangerous buildup of pressure inside the eye, a painful condition known as glaucoma.
How it presents
Owners typically notice dark spots on the whites of the eyes or the colored iris when the dog is between 5 and 10 years old. As the disease progresses, it can cause visible eye redness, cloudiness, signs of pain, and eventual vision loss.
Treatment
The condition is incurable and requires lifelong management with eye drops, or surgical removal of the eye in advanced cases, with costs ranging from €1,500 to €7,000. Since there is no DNA test, regular clinical eye examinations are essential to monitor breeding dogs.
