Congenital duplication of the lens. (1/187)

A case of reduplication of the lens with uveal coloboma is described. This is a rare condition and, unlike the two previously reported cases, the other ocular structures and adnexae appeared normal.  (+info)

Clinical characteristics of CHARGE syndrome. (2/187)

CHARGE syndrome, first described by Pagon, was named for its six major clinical features. They are: coloboma of the eye, heart defects, atresia of the choanae, retarded growth and development including CNS anomalies, genital hypoplasia and/or urinary tract anomalies, and ear anomalies and/or hearing loss. We experienced three cases of CHARGE syndrome who displayed ocular coloboma, heart defects, retarded growth and development, and external ear anomalies, and we also review the previously reported literature concerning CHARGE syndrome.  (+info)

Looking behind a pathological blind spot in human retina. (3/187)

Recent work suggests that dichoptic lateral interactions occur in the region of the visual field of one eye that corresponds to the physiological blind spot in the other eye (Tripathy, S. P., & Levi, D. M. (1994). The two-dimensional shape of spatial interaction zones in the parafovea. Vision Research, 34, 1127-1138.) Here we ask whether dichoptic lateral interactions occur in the region of the visual field of one eye that corresponds to a pathological blind spot, a retinal coloboma in the other eye. To address this question we had the observer report the orientation of a letter 'T' presented within this region in the presence of flanking 'T's presented to the other eye around the coloboma. A large drop in performance was seen due to the flanks, showing the existence of dichoptic lateral interactions in this monocular region. The presence of these dichoptic interactions in a region lacking direct retinal afferents from one eye is consistent with the proposition that long-range horizontal connections of the primary visual cortex mediate these interactions.  (+info)

Demonstration of exclusive cilioretinal vascular system supplying the retina in man: vacant discs. (4/187)

PURPOSE: To report the fluorescein angiographic and Doppler ultrasonographic findings in a patient with apparent exclusive ciliary vascular supply of the retina of both eyes. METHODS: Case report. RESULTS: The ophthalmoscopic appearance of all arterial vessels emanating from both discs was consistent with a cilioretinal origin. Retinal veins also entered each disc peripherally near the margin, leaving the central part of each disc vacant. Fluorescein angiography showed filling of all arterial vessels simultaneous with the early-phase choroidal background flush bilaterally. Color and power Doppler ultrasonographic imaging demonstrated unequivocally the absence of central retinal vessels within the optic nerves. Both discs were normal in size and excavated with central glial tissue present. The clinical history of monocular, alternating episodes of failing vision with partial resolution and the retinal pigmentation patterns bilaterally were consistent with, though not conclusive for, previous episodes of serous retinal detachments. Coincident systemic anomalies consisted of small kidneys with reduced renal parenchyma discovered on ultrasonography, along with chronic interstitial nephritis. CONCLUSIONS: The ophthalmoscopic appearance of optic discs with apparent all-cilioretinal vascular supply has been reported previously, but proof of the absence of central retinal vessels requires Doppler ultrasonographic evidence corroborated by angiographic findings, as exemplified in our case report. We describe the association of this disc anomaly with renal parenchymal disease and its distinction from colobomatous defects.  (+info)

Dysgenesis of the internal carotid artery associated with transsphenoidal encephalocele: a neural crest syndrome? (5/187)

We describe two original cases of internal carotid artery dysgenesis associated with a malformative spectrum, which includes transsphenoidal encephalocele, optic nerve coloboma, hypopituitarism, and hypertelorism. Cephalic neural crest cells migrate to various regions in the head and neck where they contribute to the development of structures as diverse as the anterior skull base, the walls of the craniofacial arteries, the forebrain, and the face. Data suggest that the link between these rare malformations is abnormal neural crest development.  (+info)

Pax2 in development and renal disease. (6/187)

Pax genes are associated with a variety of developmental mutations in mouse and man that are gene dosage sensitive, or haploinsufficient. The Pax2 gene encodes a DNA binding, transcription factor whose expression is essential for the development of the renal epithelium. Both gain and loss of function mutants in the mouse demonstrate a requirement for Pax2 in the conversion of metanephric mesenchymal precursor cells to the fully differentiated tubular epithelium of the nephron. However, Pax2 expression is down-regulated as cells leave the mitotic cycle. Humans carrying a single Pax2 mutant allele exhibit renal hypoplasia, vesicoureteric reflux, and optic nerve colobomas. Conversely, persistent expression of Pax2 has been demonstrated in a variety of cystic and dysplastic renal diseases and correlates with continued proliferation of renal epithelial cells. Thus, Pax2 misexpresssion may be a key determinant in the initiation and progression of renal diseases marked by increased or deregulated cell proliferation.  (+info)

Bitemporal pseudohemianopia related to the "tilted disk" syndrome: CT, MR, and fundoscopic findings. (7/187)

We describe a case of the "tilted-disk" syndrome in a patient with a bitemporal field depression (a pseudohemianopia). CT and MR imaging showed thinning and prolapse of the nasal sectors of the posterior walls of the globes and flattening of the temporal portion of the globes.  (+info)

The homeodomain protein vax1 is required for axon guidance and major tract formation in the developing forebrain. (8/187)

The homeodomain protein Vax1 is expressed in a highly circumscribed set of cells at the ventral anterior midline of the embryonic CNS. These cells populate the choroid fissure of the optic disk, the body of the optic stalk and nerve, the optic chiasm and ventral diencephalon, and the anterior midline zones that abut developing commissural tracts. We have generated mutant mice that lack Vax1. In these mice (1) the optic disks fail to close, leading to coloboma and loss of the eye-nerve boundary; (2) optic nerve glia fail to associate with and appear to repulse ingrowing retinal axons, resulting in a fascicle of axons that are completely segregated from optic nerve astrocytes; (3) retinal axons fail to penetrate the brain in significant numbers and fail to form an optic chiasm; and (4) axons in multiple commissural tracts of the anterior CNS, including the corpus callosum and the hippocampal and anterior commissures, fail to cross the midline. These axon guidance defects do not result from the death of normally Vax1(+) midline cells but, instead, correlate with markedly diminished expression of attractive guidance cues in these cells. Vax1 therefore regulates the guidance properties of a set of anterior midline cells that orchestrate axon trajectories in the developing mammalian forebrain.  (+info)

Optic nerve coloboma refers to one of two distinct things:. 1. An abnormal optic nerve that is deeply "excavated" or hollowed out. In some cases it can also be referred to as an optic nerve pit. The optic nerve is the bundle of nerve fibers that relays the light signals from the eye to the brain.. 2. A uveal coloboma that is large enough to involve the optic nerve, either the inferior portion or the entire optic disc.. Read more articles on Coloboma. ...

Mutations in human and/or mouse homologs are associated with this disease. Synonyms: coloboma of eye; coloboma of macula; congenital ocular coloboma
Typical colobomas are located inferiorly and slightly nasally, resulting from failure of closure of the fetal fissure. The fetal fissure closes first in the region of the equator, with progressive closure anteriorly and posteriorly from that point. Failure of the fetal fissure to close posteriorly results in absence of choroid, pigment epithelium, and retina in that area.2 The choroidal net seems to develop wherever mesoderm is in contact with pigmented epithelium. The choroid appears pari passu with the retinal pigment, and closure of the fetal fissure is not always constant.3 Case 3 demonstrates a chorioretinal coloboma positioned superior to the optic disc (fig 1C). Donoso et al1 have demonstrated such a lesion linked to the true optic disc with retinal vessels. An alternative more plausible hypothesis is that an inflammatory focus caused such a peripapillary chorioretinal coloboma.. We demonstrate a double blind spot by Humphrey automated visual field testing (fig 2A). Two distinct blind ...
Coloboma is an ocular birth defect resulting from abnormal development of the eye during embryogenesis. It is defined as a congenital defect in any ocular tissue, typically presenting as absent tissue or a gap, at a site consistent with aberrant closure of the optic fissure. Failure of fusion can lead to coloboma of one or multiple regions of the inferior portion of the eye affecting any part of the globe traversed by the fissure, from the iris to the optic nerve, including the ciliary body, retina, and choroid. Coloboma is also frequently associated with small (microphthalmic) or absent (anophthalmic) eyes as part of an interrelated spectrum of developmental eye anomalies, and can affect either one or both eyes (summary by Kelberman et al., 2014). (120200) ...
Uveal coloboma is a rare eye malformation caused by failure of the optic fissure to close during the fifth to seventh weeks of foetal life. The risk of retinal detachment increases with age in colobomatous eyes. Preventive measures such as early detection of the retinal break , prophylactic laser photocoagulation along the coloboma margin, confer a significant benefit in reducing this risk of retinal detachment. Difficulties linked to the diagnosis and management of uveal colobomas in developing countries setting are presented in this study.

Morning glory disc is a term introduced by Kindler17consisting of an enlarged excavated disc with fibroglial appearing tissue at its centre, an elevated subretinal peripapillary annulus of chorioretinal pigmentary change, and abnormal vessels radiating outwards. This congenital anomaly was likened to the withering morning glory flower from which it derives its name. A spectrum of changes have been described in the morning glory disc.18 19Peripapillary staphylomas are not commonly associated with other ocular or systemic anomalies20 although there are reports of its association with midline clefting problems.13 14 Brodskyet al 14 have also described atypical retinochoroidal coloboma in five patients with dysplastic discs and transsphenoidal encephalocele. We found this to be present in only one of our cases.. The relatively normal appearance of the disc and vessels in peripapillary staphyloma suggest that the development of these structures is complete before the onset of the staphylomatous ...

The eye derives from three embryologic germ layers. Neuroectoderm gives rise to the optic vesicle; neural crest cells are responsible for migration to the anterior chamber of the developing eye. Ectoderm is responsible for the formation of the lens placode. Neuroectodermal and mesodermal cells participate in the closure of the optic fissure. The variety of cells and tissue types involved explains variability of phenotypic abnormalities of the eye (see Table 29-1) (Warburg, 1993). The embryonic optic fissure is formed from invagination along the inferior aspect of the optic cup and optic stalk at the 5-to-8-mm stage of gestation. This fissure allows the ingress of the hyaloid artery and egress of retinal axons through the optic nerve. In the normal eye, the embryonic optic fissure closes at 33 to 44 days after conception. If the fissure fails to fuse, a defect in the neuroectodermal and uveal tissues will be produced, forming a coloboma. The coloboma is a layer of sclera lined by maldeveloped ...

Purpose : Microphthalmia, anophthalmia and coloboma (MAC spectrum) are structural ocular disorders that are sources of childhood blindness. These disorders are highly genetically heterogeneous; however, many cases remain without genetic diagnoses. Mutations in MAB21L2 have been previously associated with MAC phenotypes in human patients and confirmed in zebrafish model. This study tested the hypothesis that MAB21L family member, MAB21L1, may also participate in ocular development and contribute to disorders. Methods : We examined 276 human patients with developmental ocular conditions, including MAC spectrum anomalies. Samples were screened by Sanger Sequencing of full-length MAB21L1 coding region. To further study MAB21L1, we utilized zebrafish model to analyze expression and function in development. To do so, we carried out in situ hybridization of 18-72 hpf wild-type embryos using a mab21l1 probe. We also generated mab21l1-deficient lines using TALENs. Results : Human samples revealed one ...
MACS conditions are likely to be caused by a disruption in the way the eye develops in the baby during early pregnancy. This can be due to an alteration in an important gene for eye development, environmental factors - such as drugs or infection in pregnancy - or a combination of the these things. However, while some families have been given a genetic diagnosis, others are no closer to knowing why their child has been affected by MACS and its related conditions.. MACS is supporting the work of specialist eye consultant and geneticist Professor Nicola Ragge, who has been responsible for the discovery of many genes linked to Microphthalmia, Anophthalmia and Coloboma. We are contributing towards the costs of a part-time Family Co-ordinator based at Oxford Brookes University who is responsible for recruiting and liaising with families involved in the research and keeping them up to date on progress and findings in relation to their specific cases..

Purpose : Transcriptional coactivator YAP1 is a major downstream effector of the evolutionarily conserved Hippo pathway that controls organ size by regulating stem cell/progenitor cell proliferation and apoptosis during early development. The importance of YAP1 to the eye was further illustrated by the discovery of the heterozygous mutations in YAP1 causing coloboma in man, and the mutation in YAP1 binding domain of TEAD1 responsible for Sveinssons chorioretinal atrophy (SCRA). However, YAP1 function in maintenance of RPE phenotype has not been investigated. This study aims to dissect YAP1 function and its regulatory mechanism in RPE cells. Methods : To directly test the role of YAP1 in the differentiated RPE, we crossed Yap1 floxed mice with these carrying a Cre recombinase driven by the Best1 promoter, which is activated in the differentiated RPE cells. We investigated the phenotypes progressively developed in the Yap1-/- RPE in a timecourse up to 12 months old, using (1) EM for ...

This is a good question which I have thought about a lot. It is an academic question, a theoretical one really because there is no cure for coloboma and there never will be. But if a cure was found I would not use it. My reason for this is simple: the way I see is part of me. It has defined the way I think, behave anf feel since I was born. I cannot imagine myself without my blindness. If I suddenly regained my sight I think I would experience the kind of mourning that the sighted feel when they suddenly lose their sight. I bet you dont believe me. I bet you think that I am just saying this to further my argument. But you are wrong. I am proud of the way I look (in both senses). I never wish I could see perfectly. Sometimes I wonder if seeing better would make my life less complicated but I have never longed for sight and Im certain that I would refuse a cure. ...

As I stated above, there is no known cause of HP. It can be congenital (present from birth) or acquired (happens later in life). There may be other problems associated with HP such as optic nerve hypoplasia (incomplete development of the nerves to the eyes) or cleft lip and palate (incomplete closure of the roof of the mouth and upper lip). If you acquire HP later in life, it can be a result of a head injury, infection, tumor, surgery in the pituitary area or radiation to the head ...

Dr. Brooks studies a potentially blinding congenital malformation of the eye called uveal coloboma. The condition is caused by failure of the optic fissure to close during the fifth week of human gestation. Although the embryology leading to coloboma has been well-characterized for decades, less is known about the genetic and developmental processes responsible for this condition, making genetic counseling and molecular diagnosis difficult. The Brooks laboratory integrates clinical and genetic data from uveal coloboma patients with molecular, developmental, and biochemical studies of normal and faulty optic fissure closure in model systems. The ultimate goal of the research is to apply knowledge from clinical and laboratory studies to molecular diagnosis in families with coloboma and to devise prevention and treatment strategies. Dr. Brooks applies Mendelian and complex genetics approaches to studying uveal coloboma in patients. His laboratory has identified a unique syndrome in which abnormal ...
Kocatepe Üniv Tıp Fak Göz Hast AD, Afyon Purpose: Morning glory syndrome(MGS) is an optic nevre displasia which is mostly seen isolated but can also be together with ophthalmic, craniofacial, neurologic, and renal pathologies. Morning glory syndrome is thought to be due to a defect in embriogenesis.. Case Report: A 4-year-old girl who had esotropia in right eye was found to have right MGS and choroidal coloboma inferonasally on fundoscopic examination. Systemic evaluation was normal. After occlusion therapy there was an increase in vision.. Conclusion: In cases with MGS, both ocular and systemic evaluations are important in the diagnosis of abnormalities seen together with MGS. Morning glory syndrome is not a progressive disease and no treatment is needed. Keywords : Morning glory syndrome, choroidal coloboma, esotropia. ...
Description: CHARGE syndrome was initially defined as a non-random association of anomalies (Coloboma, Heart defect, Atresia choanae, Retarded growth and development, Genital hypoplasia, Ear anomalies/deafness). In 1998, an expert group defined the major (the classical 4Cs: Choanal atresia, Coloboma, Characteristic ears and Cranial nerve anomalies) and minor criteria of CHARGE syndrome. Individuals with all four major characteristics or three major and three minor characteristics are highly likely to have CHARGE syndrome. In 2004 a Netherlands study (Vissers, LELM, et.al) found a gene (CHD7 on 8Q12) which was implicated in 2/3 of those tested. This gene is responsible for encoding a number of DNA protein which is esential when neural crest cells are being formed and migrating. A negative genetic test for changes in the CHD7 gene can still result in a diagnosis of CHARGE ...
Choanal atresia describes the congenital narrowing of the back of the nasal cavity that causes difficulty breathing in neonate. Choanal atresia is often associated with CHARGE, Treacher Collins and Tessier Syndrome. It is a rare condition that occurs in 1:7000 live births, seen in females twice as often as males, and affects bilaterally in roughly 50% of cases. Bilateral choanal atresia is usually repaired in the newborn period. Unilateral CA repair is often deferred until age 2-3 years. Stent placement has become optional as stentless repair is gaining popularity because this technique decreases foreign body reaction in the nasopharynx which in term decreases granulation formation. Transnasal endoscopic choanal atresia repair is performed by opening the atresia bilaterally, drilling out pterygoid bone as needed, and removal of the posterior septum and vomer. Normal mucosa is preserved as much as possible by elevating a lateral based mucosal flap to prevent scarring and restenosis. Postoperatively,
Choanal atresia is a congenital disorder where the back of the nasal passage (choana) is blocked, usually by abnormal bony or soft tissue (membranous) due to failed recanalization of the nasal fossae during fetal development. It can be unilateral or bilateral. Sometimes, a unilateral choanal atresia is not detected until much later in life because the baby manages to get along with only one nostril available for breathing. Bilateral choanal atresia is a very serious life-threatening condition because the baby will then be unable to breathe directly after birth as babies are obligate nasal breathers (they mainly use their noses to breathe). In some cases, this may present as cyanosis while the baby is feeding, because the oral air passages are blocked by the tongue, further restricting the airway. The cyanosis may improve when the baby cries, as the oral airway is used at this time. These babies may require airway resuscitation soon after birth. Sometimes babies born with choanal atresia also ...
Lee et al., (2012) identified TMEM138 as a ciliary gene associated with JS (JBTS16), and performed the first mutation screening in a large group of JS cases. Three Emirati families, one Omani family, and two Egyptian families were reported, with affected members exhibiting the characteristic molar tooth sign. Among the Emirati families, 2 children from one family presented with ocular features including oculomotor apraxia (OMA) and coloboma. In the second family, 3 children presented with similar ocular features in addition to cystic kidneys and polydactyly each reported in 1 sibling; one sibling is deceased. In the third family, 3 adult siblings presented with retinal dystrophy. In the Omani family, 1 infant presented with OMA and coloboma, as well as cystic kidneys and hypertension; the family has 6 deceased siblings. Lastly, in the 2 Egyptian families only characteristic ocular features presented including OMA and coloboma presenting in 1 individual from 1 family, and OMA presenting in 1 ...

In this study, we screened 6 genes for mutations in 9 Chinese families with congenital cataract and microcornea. Three mutations were identified in 3 of the 9 (30%) families, including a c.34C,T (p.Arg12Cys) in CRYAA, and a c.136G,A (p.Gly46Arg) and a c.116C,G (p.Thr39Arg) in GJA8, respectively. CRYAA is located in 21q22.3 and encodes the α-A-crystallin in lens epithelial cells and fiber cells. α-A-crystallin is a member of small heat shock proteins with the chaperone activity which contributes to keeping lens transparent [6,10,27]. Up to now, there were eight mutations of CRYAA found in sixteen families most of which involved substitutions from or to arginine [5]. And the corresponding phenotypes of the mutations were related with congenital cataract with or without microcornea, microphthalmia, or iris coloboma. We found a known c.34C,T (p.Arg12Cys) mutation in CRYAA of three patients from a family with congenital nuclear cataract and microcornea. Previously, this mutation has been identified ...

The ophthalmological characteristics of three patients, two male siblings and their father, with diagnosis of North Carolina macular dystrophy were presented. This is a genetic dysfunction that causes congenital or early onset macular degeneration. It is characterized by a dominant autosomal heredity, with complete penetrance, genetically mapped in the chromosome 6q16. The lesions are mainly stationary. The funduscopic manifestations vary. The type of lesion is mainly stationary whereas funduscopic manifestations are varied. The dysciform lesion in the macular area and decrease of the macular thicness according to the macular coloboma prevailed, with identical particularities in the three patients. The visual acuity varied from 0.6 to 0.2.. Palabras clave : Macular dystrophy; North Carolina; dominant autosomial; chromosome; ...

Swedish pioneered the PFO treatment, which involves using a special device - a tiny, double-umbrella apparatus - to seal a small congenital defect in the heart known as a patent foramen ovale (PFO). A PFO results from incomplete closure after birth in the atrial septum, which is a thin wall separating the upper chambers of the heart. It has been implicated as a potential cause for unexplained strokes in young adults. Repairing the defect may therefore reduce the patients future stroke risk.. Like PFO, an atrial septum defect (ASD) results from incomplete closure after birth in the wall between the left and right atria. About 7 percent of congenital heart defects fall into this category, and if the defect is large enough, oxygen-rich blood from the left atrium flows back into the right side of the heart and is pumped back to the lungs instead of to the rest of the body. This results in more work for the heart. Patients with large ASDs experience shortness of breath with physical exertion. ...
The reported incidence of CHARGE Syndrome ranges from 0.1 to 1.2/10,000 and depends primarily on professional recognition. It is not known to be related to any illness, exposure to drugs or alcohol intake during pregnancy, and typically it does not occur to more than one person in a family. It is very rare, and cannot be predicted. Coloboma mainly affects the retina. Major and minor congenital heart defects (commonest cyanotic heart defect is tetralogy of Fallot) occur in 75 80% of patients. Choanal atresia may be membranous or bony, bilateral or unilateral, and is present in 50 60 percent of cases. Mental retardation (ranging from minimal to profound retardation) is another common feature. Under-development of external genitalia is a common finding in males but is less apparent in females. Ear abnormalities include classical finding of unusually shaped ears and hearing loss (conductive and/or nerve deafness resulting mild to severe deafness).. The cause of CHARGE is not known.

Life is unpredictable and a world is naturally shaken up a bit when a baby is born. We had expected to experience some measure of unpredictability with our first child. However, when our daughter, Zoe, was born in the Fall of 2003 we knew our lives were going to change in a way we had never prepared. In some ways prenatal screening had prepared us for the physical differences in our child born with a significant cleft lip and palate. We did our research and knew the surgeries she would need would be extensive along with the feeding obstacles and we were ready for that challenge. However, we were unprepared for some of the additional diagnoses that came along the way. In the hospital she was diagnosed with a coloboma in her right eye which would lead to patching for years, and she was given "hard of hearing diagnoses" when she failed her newborn screening exam 3 times. Around the age of 18 months it was apparent that Zoe was experiencing some further delays and we went for more evaluations. ...
CHARGE association is a non-random collection of congenital anomalies. The condition is becoming more widely known to medical and educational professionals. The number of children diagnosed is increasing, probably because of the greater awareness of this condition. This paper considers some of the long-term management problems which are often deferred in the early months, when acute life threatening problems take priority. Questionnaires were sent to parents via the CHARGE Association Family Support Group, UK. Thirty-nine were returned and incomplete information was sought by personal contact or telephone. The majority of children were known professionally to one or both authors and information was therefore checked from medical and educational notes. There is still widespread misunderstanding about the impact of multiple disability, especially when this includes multi-sensory impairment, on the early development of the child. Therefore, the information collected from the study has been from an ...

CHARGE association, or syndrome as it is now known, is a condition where a number of congenital malformations are non-randomly associated in a recognizable pattern. There are two sets of diagnostic criteria for CHARGE syndrome which are in common usage at present (Blake et al., 1998; Verloes, 2005). The etiology of CHARGE syndrome was unknown. We identified twin girls with CHARGE syndrome and a de novo apparently balanced chromosome translocation 46,XX,t(8;13)(q11.2;q22). By mapping the chromosome translocation breakpoints we found that the gene chromodomain-helicase-DNA-binding protein 7 (CHD7) located at 8q12 was disrupted in these girls. CHD7 has a genomic length of 188kb with 9000 coding bases over 37 exons. It has a putative function as a transcription factor which makes it a good candidate gene for a condition which affects multiple body systems. Concurrently with this study Vissers et al (2004) identified CHD7 as a cause of CHARGE syndrome. They found two individuals with CHARGE syndrome ...
Neonates have to breathe through their nose because the entire length of their tongue abuts against the hard and soft palates, and because the high position of their epiglottis (at the level of the third and fourth cervical vertebrae compared with the fifth and sixth vertebrae in adults) causes increased resistance of the oral airway.. The nasal passages can be divided into 3 anatomic regions: pyriform aperture, middle nasal cavity and posterior choana. Anterior nasal obstructions are usually due to isolated pyriform aperture stenoses or a lack of cleavage of the frontal hemispheres, which results in holoprosencephaly in addition to a central maxillary incisor. Posterior obstructions, such as bilateral choanal atresia, are usually part of the CHARGE association (a syndrome of associated birth defects, including coloboma of the eye, heart anomaly, choanal atresia, growth retardation, and genital and ear anomalies).. Midnasal obstructions are often due to nasal edema from inflammation and ...

Alport Syndrome. In 1927, A. Cecil Alport first described a syndrome associated with hearing loss also marked by hematuria. The syndrome has a prevalence of 1 in 5000, with 85% of patients having the X-linked form. Non-congenital, sensorineural deafness very frequently, though not always, accompanies the nephropathy of Alport syndrome. The severity of renal disease varies with regard to the type of Alport syndrome and the sex of the individual. It should be noted that patients with this syndrome are also at increased risk for hypertension.. In addition to hearing impairment and renal disease, a variety of ocular lesions and defects are common in patients with Alport syndrome, including anterior lenticonus (congenital condition of the lens in which the surface is conical), progressive distortion of the lens, and pigmentary changes. In fact, the presence of anterior lenticonus is strongly suggestive of a diagnosis of Alport syndrome. CHARGE Association. The CHARGE acronym stands for coloboma of ...

From NCBI Gene:. The product of this gene belongs to the claudin family. It plays a major role in tight junction-specific obliteration of the intercellular space, through calcium-independent cell-adhesion activity. Defects in this gene are the cause of hypomagnesemia renal with ocular involvement (HOMGO). HOMGO is a progressive renal disease characterized by primary renal magnesium wasting with hypomagnesemia, hypercalciuria and nephrocalcinosis associated with severe ocular abnormalities such as bilateral chorioretinal scars, macular colobomata, significant myopia and nystagmus. Alternatively spliced transcript variants encoding distinct isoforms have been identified for this gene. [provided by RefSeq, Jun 2010]. From UniProt: ...
The authors review the utility of genetic testing in ophthalmic disorders - precise diagnosis, accurate prognosis, genetic counseling, prenatal diagnosis, and entry into gene-specific therapeutic trials. The prerequisites for a successful outcome of a genetic test are an accurate clinical diagnosis, a careful family history that guides which genes to study, and genetic counseling (both pre-test and post-test). The common eye disorders for which genetic testing is commonly requested are briefly discussed - anophthalmia, microphthalmia, coloboma, anterior segment dysgenesis, corneal dystrophies, cataracts, optic atrophy, congenital glaucoma, congenital amaurosis, retinitis pigmentosa, color blindness, juvenile retinoshisis, retinoblastoma etc ...

Parents of children with CHARGE should be encouraged to become IN CHARGE and very active advocates for their children in order to ensure that an educational program is made that will allow each child to reach their full potential. All children regardless of their final cognitive abilities will require special support in schools to ensure that they maximize their potentials and develop into the most productive people that they can be. In an educational setting all involved must be aware of the special needs a child with CHARGE may have. Teachers of children with CHARGE Syndrome have to be aware of all areas affected by the disease. Because CHARGE can affect the eyes, ears, and brain it is most important that all members of the educational team (teacher of the deaf and hard of hearing, teachers of the visually impaired, audiologists, pediatricians, parents, etc.) Taking each of these into account is vital to the success of the child and family in an educational setting. ...

The inheritance and some developmental effects of a new allele of ocular retardation (orJ) are described. Affected animals or 12 days of gestation, show reduced cell death in the eye cup and thickening of the inner wall of the optic fissure. At 11 to 13 dyas of gestation orJ/orJ eyes grafted to the testis do not produce retina as their orJ+ littermates do. Adult animals have small eyes with closed lids, abnormal retinal layers, and no optic nerve.

Congenital nystagmus onset is typically between 6 weeks and several months of age. If it starts after 6 months of age, this is considered acquired and may require imaging studies. Infantile nystagmus tends to be divided into two groups, depending on the underlying problem. One group arises from an abnormal afferent (or sensory) system, and the other from an abnormal efferent (motor) system. The efferent type is more common, but sometimes patients have early nystagmus due to afferent, or vision system, problems. In patients with early nystagmus secondary to afferent problems, conditions that limit their vision are thought to be responsible for the development of their nystagmus. The brain needs feedback from the eyes, through vision, to learn to keep them steady. Conditions that can be associated with this type of nystagmus include congenital cataracts, optic nerve hypoplasia, Lebers congenital amaurosis, achromatopsia, oculocutaneous albinism, aniridia, choroidal coloboma, severe refractive ...

The ability to identify the clinical nature of the recurrent duplication of chromosome 17q12 has been limited by its rarity and the diverse range of phenotypes associated with this genomic change. In order to further define the clinical features of affected patients, detailed clinical information was collected in the largest series to date (30 patients and 2 of their siblings) through a multi-institutional collaborative effort. The majority of patients presented with developmental delays varying from mild to severe. Though dysmorphic features were commonly reported, patients do not have consistent and recognizable features. Cardiac, ophthalmologic, growth, behavioral, and other abnormalities were each present in a subset of patients. The newly associated features potentially resulting from 17q12 duplication include height and weight above the 95th percentile, cataracts, microphthalmia, coloboma, astigmatism, tracheomalacia, cutaneous mosaicism, pectus excavatum, scoliosis, hypermobility, ...
Objective: The objective of this study is to identify genetic causes of inherited eye conditions through whole exome or whole genome sequencing. This includes identifying mutations in known genes or novel genes for recognized conditions, as well as identifying mutations in novel genes for previously uncharacterized genetic conditions involving the eye.. Study Population: We plan to recruit 310 participants, to include both probands with an eye condition under study and unaffected family members. Ideally unaffected family members will be parents of a proband.. Design: Participants will be recruited through other pre-existing NIH protocols, such as the NEI Evaluation and Treatment protocol (08-EI-0169), the NEI Screening protocol (08-EI-0102), and the Genetics of Uveal Coloboma protocol (13-EI-0049). Self-referred patients or patients referred by an outside clinician will be screened for eligibility under a pre-existing NIH protocol. Phenotyped patients eligible for participation and their ...
COMPLEXION AND FEATURES 43 The details of the features as regards the eyes, nose, ears, lips, chin and teeth should be carefully noted. The irises of the Indians are generally dark brown, but are grey in a few cases, especially among the Punjabis. In some individuals the colour of one iris may differ from that of the other. Coloboma or hiatus may be found, if an operation has been performed on the iris. The bridge of the nose may be narrow, flat or broad, and the nostrils may be distended or the reverse. The ears may be small or large in size. Their lobules may be free or adherent to the face. The lips may be thin or thick, and the upper lip may hang over the lower lip, or may look shorter owing to the upper incisor teeth projecting outwards. The chin may be rounded, square, protruding or double from excessive fat.

Associated symptoms and findings may vary in range and severity from case to case. However, Trisomy 13 Syndrome is often characterized by craniofacial, neurologic, heart (cardiac), and/or other defects.. Affected infants typically are unusually small and have feeding difficulties. Various craniofacial malformations are frequently present, such as an abnormally small head (microcephaly) and a sloping forehead; unusual wideness of the soft spots (fontanelles) at the front and back of the skull; incomplete closure of the roof of the mouth (palate); a small jaw; scalp ulceration at the top of the head; and/or low-set, malformed ears. Other characteristics may include a short neck; loose skin folds over the back of the neck; and/or the presence of a benign lesion or birthmark consisting of abnormal clusters of blood vessels (capillary hemangiomas), most frequently on the center of the forehead. In addition, eye (ocular) abnormalities may include unusually small eyes (microphthalmia); partial absence ...
A delay in liver regeneration after partial hepatectomy (PHx) leads to acute liver injury, and such delays are frequently observed in aged patients. BubR1 (budding uninhibited by benzimidazole-related 1) controls chromosome mitotic segregation through the spindle assembly checkpoint, and BubR1 down-regulation promotes aging-associated phenotypes. In this study we investigated the effects of BubR1 insufficiency on liver regeneration in mice. Low-BubR1-expressing mutant (BubR1(L/L)) mice had a delayed recovery of the liver weight-to-body weight ratio and increased liver deviation enzyme levels after PHx. Microscopic observation of BubR1(L/L) mouse liver showed an increased number of necrotic hepatocytes and intercalated disc anomalies, resulting in widened inter-hepatocyte and perisinusoidal spaces, smaller hepatocytes and early-stage microvilli atrophy. Up-regulation of desmocollin-1 (DSC1) was observed in wild-type, but not BubR1(L/L), mice after PHx. In addition, knockdown of BubR1 expression caused

Microphthalmos is a rare congenital anomaly characterized by reduced eye size and visual deficits of variable degrees. Sporadic and hereditary microphthalmos has been associated to heterozygous mutations in genes fundamental for eye development. Yet, many cases are idiopathic or await the identification of molecular causes. Here we show that haploinsufficiency of Meis1, a transcription factor with an evolutionary conserved expression in the embryonic trunk, brain and sensory organs, including the eye, causes microphthalmic traits and visual impairment, in adult mice. By combining the analysis of Meis1 loss-of-function and conditional Meis1 functional rescue with ChIP-seq and RNA-seq approaches we show that, in contrast to Meis1 preferential association with Hox-Pbx binding sites in the trunk, Meis1 binds to Hox/Pbx-independent sites during optic cup development. In the eye primordium, Meis1 coordinates, in a dose-dependent manner, retinal proliferation and differentiation by regulating genes ...

RESULTS. There were no surgical complications for the 23 orbital decompressions.Proptosis reduction was achieved in 22 (96%) eyes. The mean proptosis reduction was 4.6 mm (median, 5.0 mm; range, 1.0-8.0 mm). The postoperative intra-ocular pressure decreased after surgical decompression in 20 (87%) eyes with a mean reduction of 11 mm Hg (median, 6 mm Hg; range, 1-35 mm Hg). Of the 15 eyes with incomplete closure of the eyelid before the operation, 11 (73%) had complete eyelid closure after surgical decompression. Of the other four eyes that had incomplete closure, the gaps were reduced. The visual acuity was improved for 16 (70%) eyes with a median improvement of 3 Snellen lines (range, 1-8 lines ...
Editor-The branchio-oculo-facial syndrome (BOFS) is characterised by a branchial cleft sinus or linear skin lesion behind the ear, lacrimal duct obstruction, colobomata of the iris/retina, hypertrophy of the lateral pillars of the philtrum ("pseudocleft"), an asymmetrical nose with a broad tip, and auricular and lip pits. Premature greying of the hair is also observed.1 Inheritance is autosomal dominant (OMIM 113620).2 Several anomalies common to both BOF and BOR (branchio-oto-renal) syndromes have been reported.3 McCool and Weaver4 reported three cases with BOF and unilateral renal agenesis. This anomaly is not frequent in BOFS but is characteristic for patients with BOR, and hence a contiguous gene syndrome or the presence of different mutations within a single gene have been suggested.4 Recently, the BOR gene was identified by positional cloning on chromosome 8q13.3 and mapped between markers D8S1060 and D8S1807.5 The gene was named "eyes absent-like 1" (EYA1), the human homologue of the ...
Since the young infant is primarily a nasal breather, any degree of nasopharyngeal obstruction may result in significant increase in work of breathing. The large tongue of infants and small children can occlude the oropharynx, especially with altered mental status and decreased muscle tone. Interventions such as tilting the head or lifting the chin may correct this effect. Insertion of an orotracheal or a nasotracheal airway may assist in alleviating respiratory distress. Older children will frequently present with enlarged tonsillar and adenoidal tissues. The pediatric trachea is easily compressible because of incomplete closure of the cartilaginous rings. Any maneuver that overextends the neck contributes to compression of this structure and secondary upper airway obstruction. ...

Three patients had microphthalmos with cyst in one orbit and contralateral congenital cystic eye, microphthalmos alone, or microphthalmos with cyst. Four eyes were examined histopathologically. The microphthalmic eye demonstrated a spectrum of anterior segment abnormalities, retinal disorganization and gliosis, and a choroidal and scleral colomboma. The cyst connected to the colobona consisted of an outer fibrovascular layer and inner gliotic neuroectodermal layer. The cyst probably originated from proliferation of neuroectodermal tissue at the edge of a persistently open embryonic fissure ...
In the present study, we further analyzed flanking genes of 3p25 syntenic members identified in the Torafugu genomic database and determined their expression with cDNA isolated from ovary and liver. CECR5 was found in the upstream of RAF1 and CECR6 downstream of MKRN1 in Torafugu genomic scaffolds. In addition, the last exon of IL17R was located downstream of CECR6 on the opposite strand, in the same configuration as seen in human chromosome 22q11, with a high degree of conservation in sequence similarity and exon/intron structures. These results supported that the major part of the long arm of human chromosome 22 (q11 to q13), with a collinear order of IL17R, CECR6, and CECR5 (22q11) and SYN3 (22q12) and PPARA (22q13), is homologous to the ancestral 3p25 synteny containing a similar paralogous set of reference genes (SYN, PPAR, MKRN, RAF, CECR5, CECR6, and IL17R).

Im a huge fan of blowouts these days, and if there are a few events over a few days its a no-brainer for me because I can get so much more "bang" for my buck. (I normally pay about $40 for a blowout, not counting tax and tip, but you can also blowout your own hair. Even if youre doing it yourself, with the time and energy required, you may want to make those last for days as well!) Right now a blowout can last about 3 days for me, easily, but there were points in my life when I could make it last for 5 days. (Pictured: me on Day 3 - I would have let this one go to Day 4 actually but I wanted to workout.). I think it comes down to a few simple rules:. a) Train your hair. This is my own secret theory, but here goes: the more often you wash your hair, the more often it thinks it needs to be washed. (The NYT has covered this sort of thing ...

Branchiooculofacial syndrome (BOFS; MIM 113620) is an autosomal dominant developmental disorder characterized by cutaneous defects in the cervical or infra- and/or supra-auricular region, lacrimal duct obstruction, and ocular anomalies such as microphthalmia or anophthalmia, coloboma, ptosis and cataract. Craniofacial features include cleft or pseudocleft lip/palate, dolichocephaly, malformed pinnae, low set ears and broad nasal tip. Additional findings may include inner ear malformations, temporal bone anomalies, conductive, mixed or sensorineural hearing loss, ectopic dermal thymus and various ectodermal anomalies. Growth deficiency, renal anomalies and mild mental retardation are less frequent findings. Intrafamilial clinical variability may be marked. To date, genetic heterogeneity has not been reported. BOFS is caused by mutations in the TFAP2A gene. It codes for transcription factor AP-2-alpha protein, which is a sequence-specific DNA-binding protein that interacts with inducible viral and ...

The most common disease of the eyelids is hordeolum, known commonly as a sty, which is an infection of the follicles of the eyelashes, usually caused by infection by staphylococci. Internal sties that occur inside the eyelid and not on its edge are similar infections of the lubricating Meibomian glands. Abscesses of the eyelids are sometimes the result of penetrating wounds. Several congenital defects of the eyelids occasionally occur, including coloboma, or cleft eyelid, and ptosis, a drooping of the upper lid. Among acquired defects are symblepharon, an adhesion of the inner surface of the eyelid to the eyeball, which is most frequently the result of burns. Entropion, the turning of the eyelid inward toward the cornea, and ectropion, the turning of the eyelid outward, can be caused by scars or by spasmodic muscular contractions resulting from chronic irritation. The eyelids also are subject to several diseases of the skin such as eczema and acne, and to both benign and malignant tumors. ...
From UniProt:. Atrial septal defect 2 (ASD2): A congenital heart malformation characterized by incomplete closure of the wall between the atria resulting in blood flow from the left to the right atria.
