[Late onset lens particle glaucoma in Marfan syndrome].

CASE REPORT: A case is presented of an acute onset lens particle glaucoma originating from a crystalline lens spontaneously dislocated into the vitreous for more than 20 years in a patient diagnosed with Marfan syndrome.

DISCUSSION: Marfan syndrome is a connective tissue disorder with autosomal dominant inheritance caused by fibrillin gene mutation. Ectopia lentis is the predominant ocular abnormality and a major diagnostic criterion. An association between Marfan syndrome and glaucoma has also been demonstrated. The reported case is unusual in that a complete spontaneous lens dislocation to vitreous was present and progressed to secondary lens particle open angle glaucoma.
