A 32-year-old woman presented with a progressive decrease of vision in right eye and
bilateral and severe skin eczema. The best-corrected visual acuity was 20/40 in the
right eye and 20/20 in the left eye. The patient was previously diagnosed with atopic
dermatitis. On slit-lamp examination, a shield-shaped anterior capsular cataract was
observed, as well as an important anterior blepharitis. Although posterior subcapsular
cataracts are more frequent in atopic dermatitis, shield-shaped cataracts are more
specific to this disease. Topical and systemic steroids, mechanical effect owing to
intense eye rubbing, intraocular inflammation, and decreased inducibility of superoxide
dismutase have been proposed as possible explanations of this kind of cataract. However,
the precise pathogenic mechanisms and risk factors for the development of atopic cataracts
are still not clear.
