Pigment deposits in the retrolental space of Berger: a rare feature of pigment dispersion syndrome?

Depósitos de pigmento no espaço de Berger: uma característica rara de síndrome de dispersão pigmentar?

ABSTRACT

Pigment dispersion syndrome is associated with clinical features such as Krukenberg's spindles, trabecular pigmentation, Scheie's stripe and Zentmayer's ring. Another less common feature of this syndrome is retrolental pigment deposits due to anterior hyaloid detachment or a defect in the Wieger's ligament. We present two cases of pigment deposits on the posterior lens capsule. In both cases, there is bilateral dispersion of pigment throughout the anterior segment. The retrolental deposits are unilateral in the first case and bilateral in the second. Both patients report a history of ocular trauma. This is a possible important clinical sign of pigment dispersion syndrome, rarely described.
