[PETERS ANOMALY AND PETERS PLUS SYNDROME]

Peters anomaly is characterized by a defect in the development of the anterior segment of the eye during fetal development (Anterior segment dysgenesis). This anomaly presents a broad clinical presentation ranging from minimal peripheral corneal opacity to extensive adhesions of the iris and lens with dense central corneal opacity that impairs vision. Peters Plus Syndrome is a recessive autosomal syndrome manifested by Peters anomaly, along with systemic disorders such as brachydactyly (short fingers and toes), short stature, a developmental delay, dysmorphic facial features, and may accompanied with heart and genitourinary malformations. The most common sign of Peters' anomaly is corneal opacity that appears at birth. This opacity can cause blockage of the central visual axis and cause the development of a deprivational amblyopia. In addition, the patient may suffer from glaucoma due to malformations in the angle structures as well as a shallow anterior chamber. Treatments are aimed at clearing the central visual axis as soon as possible in order to allow the visual system to mature and to avoid the development of amblyopia. Full-thickness corneal transplantation combined with Cataract surgery if necessary is the current standard of care. Optical iridoplasty is a milder surgical alternative in cases where the corneal opacity is not significant.
