The ocular pathology in a new patient with mosaic trisomy 9 comprised major anomalies and contrasted sharply with the findings in a previous case reported by us. The ocular changes in this case were, in essence, indistinguishable from those encountered in the most severe form of trisomy 13. Similarities to
trisomy 18
and 21 were further evidence of the overlap of ocular findings in autosomal trisomies. There is increasing evidence that most, if not all, chromosomes have some role in regulating ocular embryogenesis.

Ankyloblepharon filiforme adnatum (AFA) is a mild form of ankyloblepharon, in which there is partial thickness fusion of the central portion of the lid margins, sparing the canthi. Although it can be seen as an isolated sporadic congenital defect, it is important for pediatric ophthalmologists to be cognizant of its possible association with a number of anomalies. One infrequent, but nevertheless important association, is with
trisomy 18
. We present three cases of AFA in association with
trisomy 18
, and emphasize the need for clinicians to search for other abnormalities in a newborn presenting with AFA.

OPHN1 mutations cause a syndromic form of mental retardation (MR) characterized by cerebellar hypoplasia, early hypotonia, motor and speech delay, with occasional seizures and
strabismus
. Here we report on a familial chromosome duplication spanning about 800 Kb of Xq12q13.1, associated with MR and a distinctive phenotype in the affected male, but not in his heterozygous mother. The parents were healthy and non-consanguineous with a history of three pregnancies. The first resulted in the birth of a boy with MR, motor impairment and seizures. The second pregnancy was terminated because of
trisomy 18
. At the time of the third, the first affected boy was analyzed by array-CGH, which revealed a 800 Kb duplication at Xq12q13.1, encompassing three genes, including OPHN1. This mutation was inherited from his healthy mother and was not present in any of the three maternal brothers. To our knowledge this is the first report of a clinical phenotype associated with duplication of Xq12q13.

The authors report the first case of
trisomy 18
associated with a clinically detectable optic nerve pit. A female infant with a birth weight of 2,150 g was born by cesarean section to a healthy 40-year-old woman at 38 weeks of gestation.
Trisomy 18
had been diagnosed by prenatal genetic testing. Ophthalmologic examination was remarkable for bilateral narrowed palpebral fissures with punctal agenesis, corectopic pupils without reaction to light, bilateral inferior peripapillary retinochoroidal hypopigmentation, and significant optic nerve cupping in the left eye with associated temporal optic nerve pit. It has generally been accepted that optic nerve pits are a congenital anomaly. However, the pathophysiological background of optic nerve pits remains unclear and controversial. This is the first clinical and photographic documentation of an optic nerve pit in a neonate and in
Edwards syndrome
.
