Ocular findings in a case of Pierson syndrome with a novel mutation in laminin ß2 gene
2018
Pierson syndrome, an autosomal recessive disorder caused by a mutation in
laminins2 ( LAMB2 ) gene, is characterized by
congenital nephrotic syndromeand various ocular abnormalities. The ocular findings in Pierson syndrome are not well understood, because the incidence of this syndrome is very rare. We report ocular findings in a 5-month-old boy with Pierson syndrome with a novel mutation in LAMB2 . We performed a pupilloplasty for his microcoria. Ophthalmic examinations after surgery revealed that he had cataract, severe
retinal degeneration, and high myopia. Optical coherence tomography showed the collapse of retinal layer structures and a marked decrease of
choroidalthickness. Immunohistochemistry and electron microscopy examinations revealed abnormal iris differentiation and thinning or defect of basal membranes. These results suggest that the development of the iris, lens, retina, and
choroidare affected in this type of mutation.
