          Abstract

          The Ectopia lentis et pupillae is a rare genetic syndrome, congenital, autosomal recessive with variable expression, characterized by ectopia of the lens and the pupil, usually bilateral and symmetrical, but without systemic manifestations. The pathogenesis of this anomaly is still unknown, but there are theories that the change is mesodermal, neuroectodermal, combined or mechanical. This article presents a clinical case of a patient with ectopia lentis et pupillae, describing its clinical and genetic aspects, secondary ocular complications and differential diagnosis.

          A ectopia lentis et pupillae é uma síndrome genética rara, congênita, autossômica recessiva de expressividade variável, caracterizada por ectopia do cristalino e da pupila, geralmente bilateral e simétrica, sem associação com anormalidades sistêmicas. Sua patogênese ainda é desconhecida, porém se especula que haja alteração mesodérmica, neuroectodérmica, combinada ou mecânica. O artigo relata o caso clínico de um paciente portador de ectopia lentis et pupillae, descrevendo seus aspectos clínicos e genéticos, além de suas complicações secundárias e diagnósticos diferenciais.

          Ectopia lentis et pupillae syndrome in three generations.

          In nine members from three generations and in a distant relative, at least three significant characteristics of the ectopia lentis et pupillae syndrome were established including ectopia lentis, ectopia pupillae, persistent pupillary membrane, iris transillumination, and poor pupillary dilatation. All patients developed bilateral cataract before the age of 40 years, and two patients presented with intermittent acute intraocular hypertensive crises. Not only the high number of patients in one family, but also the occurrence in three generations is very exceptional for the ectopia lentis et pupillae syndrome. Although the syndrome is said to be inherited in an autosomal recessive mode, in this family, a mother to son and a mother to daughter transmission were present. Pedigree analysis yielded arguments in favour of an autosomal dominant inheritance with reduced penetrance. A biochemical correlation was not identified.

            Clinical manifestations of ectopia lentis et pupillae in 16 patients.

            The largest known series of patients with ectopia lentis et pupillae (ELeP) was clinically evaluated. Sixteen patients from eight families were characterized with respect to ocular anomalies. Variability between eyes of the same patient and among different patients was marked. In addition to the well-known but inconstant displacement of the lens and pupil, other characteristics of this protean syndrome included severe axial myopia (and associated fundus abnormalities), poor vision, retinal detachment (RD), enlarged corneal diameters, cataract, abnormal iris transillumination, poor pupillary dilatation, persistent pupillary membranes, iridohyaloid adhesions, and prominent iris processes in the anterior chamber angle.
