1/27. Multiple systemic and periocular malformations associated with the fetal hydantoin syndrome.anticonvulsants remain necessary during pregnancy and the removal of such drugs is not recommended. However, on the available evidence, the physician may expect an increased risk of malformation including eye abnormalities as has been outlined. The abnormalities include growth deficiencies and delayed motor/mental development together with dysmorphic features, the most common of which seems to be cleft lip/cleft palate. Additionally, many of these children suffer from eye abnormalities including hypertelorism, ptosis, strabismus, epicanthal folds, and in this case abnormalities of the lacrimal apparatus.- - - - - - - - - - ranking = 1keywords = hypertelorism (Clic here for more details about this article) |
2/27. Ophthalmic features of chromosome deletion 4p- (wolf-hirschhorn syndrome).By using the Giemsa banding technique we identified three patients with chromosome deletion 4p-. All had anterior segment anomalies, exotropia, blepharoptosis, antimongoloid palpebral fissures, hypertelorism, and disk abnormalities. One patient (Case 1) had Rieger's anomaly. Some clinical features in patients with 4p- are similar to those in patients with chromosome deletion 5p-, cri-du-chat syndrome, although 4p- individuals do not have the distinctive cry. The ocular features which distinguish 4p- from other deletions include normal tearing, some degree of blepharoptosis, and the preponderance of anterior segment signs.- - - - - - - - - - ranking = 1keywords = hypertelorism (Clic here for more details about this article) |
3/27. Melnick-needles syndrome.A 10-year-old female with a generalized bone dysplasia was found to have a rare condition, Melnick-needles syndrome. Characteristic clinical features of this syndrome include exophthalmos, hypertelorism, micrognathia, malaligned teeth, and large ears in a person with multiple bone deformities. In addition to the usual characteristic clinical findings, sclerocornea and cornea plana were also present in this patient. This is the first case of Melnick-needles syndrome reported in the ophthalmological literature and the first case reported with ophthalmological findings other than exophthalmos and strabismus.- - - - - - - - - - ranking = 1keywords = hypertelorism (Clic here for more details about this article) |
4/27. Bilateral microphthalmos with colobomatous orbital cyst and de-novo balanced translocation t(3;5).A term Caucasian male infant, born to a healthy non-related couple, was noted at birth to have bilateral edema and bluish discoloration of the lower eyelids. On physical examination, the eye globes were not visualized and hypertelorism was noted. Radiological imaging revealed large bilateral orbital cysts, microphthalmos, and severe optic nerve hypoplasia. Histological study of the excised orbital masses showed cysts lined by primitive, immature retinal tissue which contained neuroglial elements and scattered dysplastic rosettes. Chromosome analysis revealed an apparent balanced reciprocal translocation between the long arm of chromosome 3 and 5, i.e. 46, XY, t (3; 5) (q27; q11.2).Chromosome studies in parents were normal. To our knowledge, the association of this balanced translocation and microphthalmos with cyst has not been previously described in the English literature.- - - - - - - - - - ranking = 1keywords = hypertelorism (Clic here for more details about this article) |
5/27. Axenfeld-Rieger anomaly, hypertelorism, clinodactyly, and cardiac anomalies in sibs with an unbalanced translocation der(6)t(6;8).We describe two sibs with the unbalanced translocation der(6)t(6;8)(p25.1;q24.23), making them monosomic for 6p25.1-->6pter and trisomic for 8q24.23-->8qter. The siblings both possess Axenfeld-Rieger Anomaly (ARA), hypertelorism, clinodactyly, and cardiac anomalies, but otherwise vary in the phenotypic manifestations of this unbalanced translocation. We compare them to previously described cases and a recently proposed syndrome of ARA, atrial septal defect, and sensorineural deafness.- - - - - - - - - - ranking = 5keywords = hypertelorism (Clic here for more details about this article) |
6/27. septo-optic dysplasia as a manifestation of valproic acid embryopathy.BACKGROUND: The use of valproic acid during pregnancy has been associated with adverse fetal outcomes, including major and minor congenital malformations, intrauterine growth retardation (IUGR), hyperbilirubinemia, hepatotoxicity, transient hyperglycemia, and fetal and neonatal distress. In addition, intrauterine exposure to valproic acid has been associated with an increased risk of central nervous system abnormalities, primarily neural tube defects. optic nerve hypoplasia has been reported in association with other prenatal anticonvulsant exposures, but the occurrence of septo-optic dysplasia as a manifestation of valproic acid embryopathy has not been reported previously. RESULTS: We report on a woman who received Depakote (valproic acid) throughout her pregnancy for the treatment of a seizure disorder. The patient presented with features typical of valproic acid embryopathy, including bitemporal narrowing, hypertelorism, short palpebral fissures, epicanthal folds, microphthalmia, a flat broad nasal bridge, small mouth, hypoplastic nails, mild clinodactyly, and camptodactyly. MRI showed hypoplasia of the optic chiasm and absence of the septum pellucidum. CONCLUSIONS: We report the first case of septo-optic dysplasia associated with maternal exposure to valproic acid throughout pregnancy. This case expands the clinical phenotype of valproate embryopathy.- - - - - - - - - - ranking = 1keywords = hypertelorism (Clic here for more details about this article) |
7/27. New mental retardation syndrome associated with ocular colobomas, cleft palate, and genital, skeletal, and craniofacial abnormalities.We describe three Canadian brothers of Cree origin, with a previously undescribed pattern of malformation including distinctive craniofacial abnormalities with triangular facies, hypertelorism, low-set and posteriorly rotated ears, ocular colobomas, ptosis, brachycephaly with widely separated sutures, cleft soft palate, undescended testes, bifid scrotum and hypospadius, wide webbed neck, webbed fingers, pectus excavatum and hypersegmented sternum, and severe psychomotor retardation. The presence of normal brain imaging and physical growth distinguishes them from other syndromes with overlapping abnormalities. This is either an X-linked or autosomal recessive condition.- - - - - - - - - - ranking = 1keywords = hypertelorism (Clic here for more details about this article) |
8/27. PTPN11 mutations in leopard syndrome.leopard syndrome is an autosomal dominant disorder with multiple lentigines, congenital cardiac abnormalities, ocular hypertelorism, and retardation of growth. deafness and genital abnormalities are less frequently found. We report a father and daughter and a third, unrelated patient with leopard syndrome. Recently, missense mutations in the PTPN11 gene located in 12q24 were found to cause noonan syndrome. All three cases of leopard syndrome reported here have a Y279C mutation in the PTPN11 gene. We hypothesise that some PTPN11 mutations are associated with the typical noonan syndrome phenotype and that other mutations, such as the Y279C mutation reported here, are associated with both the noonan syndrome phenotype and with skin pigmentation anomalies, such as multiple lentigines or cafe au lait spots.- - - - - - - - - - ranking = 1keywords = hypertelorism (Clic here for more details about this article) |
9/27. Is it a new syndrome or a clinical variability in cerebro-oculo-nasal syndrome?We present a male infant 2.5-months old with asymmetric skull, anophthalmia, apparent hypertelorism, abnormal nares, unilateral cleft lip and palate, and structural abnormalities of the central nervous system. These findings are similar to cerebro-oculo-nasal syndrome except for the appearance of nose. This case is either a clinical variability in cerebro-oculo-nasal syndrome or a new entity.- - - - - - - - - - ranking = 1keywords = hypertelorism (Clic here for more details about this article) |
10/27. Acro-fronto-facio-nasal dysostosis: report of a new Brazilian family.We report on a Brazilian woman with severe mental retardation, facial and skeletal anomalies characterized by hypertelorism, eye anomalies, broad notched nasal tip, cleft lip, highly arched palate, camptobrachysyndactyly of fingers and toes, and anomalies of the feet. A similarly affected brother died at age one year. The clinical picture strongly suggest the diagnosis of the autosomal recessive acro-fronto-facio-nasal dysostosis syndrome (AFFND). Clinical and genetic aspects are discussed.- - - - - - - - - - ranking = 1keywords = hypertelorism (Clic here for more details about this article) |
