[Pigmentation on the anterior chamber angle in retinal detachment associated with atopic dermatitis].

We reported pigmentation on the anterior chamber angle in twenty-two patients suffering from atopic dermatitis. Dense pigmentation on the anterior chamber angle was observed in all eight eyes with retinal detachment and was evident before clinical recognition of detached retina. Minimal or slight pigmentation was also evident in eyes without retinal detachment. Increased pigmentation on the anterior chamber angle is a characteristic and predictive sign of retinal detachment associated with atopic dermatitis. This pigment appeared to migrate from latent breaks because of inflammation of the peripheral retina and ciliary body.
