September 24, 2018. Recent findings suggest that approximately one-quarter of infants with suspected or confirmed Zika virus exposure during the 2015-2016 Rio de Janeiro outbreak developed eye abnormalities. Researchers said that regardless of laboratory confirmation, all infants born during Zika outbreaks should be universally screened for eye abnormalities.. Irena Tsui, MD, an ophthalmologist at UCLA, and colleagues wrote that lab confirmation of Zika virus (ZIKV) infection in neonates may be difficult for several reasons, including the observation that many cases of ZIKV infection are asymptomatic. These cases, according to the researchers, tend not to get tested for the infection. Additionally, a negative test result cannot rule out infection because the virus is detectable through testing for only 3 to 16 days after symptom onset.. Read more. ...
The study describes the prevalence of multiple congenital ocular abnormalities (MCOA) in Rocky Mountain Horses and Kentucky Moutain Saddle Horses in Europe. Materials and methods: 35 RMH und KMSH were examined between 1999 and 2010. Their coat color were chocolate (24), seal brown (7), and one each of bay, black, chestnut and palomino. Ciliary body cysts (CBC) were found in 17/35 hor- ses. Two (2/35) horses had multiple congenital ocular abnormalities consistent with anterior segment dysgenesis (ASD). None of the seal brown, black or bay horses had ocular abnormalities, while 18/24 chocolate horses had lesions. One chestnut mare had also bilateral CBC. Fourteen horses (40%) were unaffected. While the prevalence of multiple ocular abnormalities appears to be lower in Europe than in the US, the prevalence of ciliary body cysts is almost the same. Prior to breeding, RMH und KMSH should be carefully examined for the presence of CBC and MCOA ...
There is little information about the epidemiology of congenital eye anomalies in Ghana. We retrospectively reviewed the clinical records of 485 admissions to the paediatric eye centre of the Korle-Bu Teaching Hospital, Ghana [‎2004-2009]‎ and 263 were diagnosed with at least one anomaly. Visual acuity was quantitatively assessed in 209 patients and 130 had some visual impairment; 49 with bilateral and 64 with unilateral blindness. The most frequent congenital anomaly overall was cataract [‎n = 44]‎. In infants, cataract was the most frequent finding [‎28/121]‎. Toddlers most frequently presented with retinoblastoma [‎10/65]‎. Glaucoma was the most frequent anomaly in preschool [‎9/39]‎ and school [‎10/38]‎ children. We conclude that avoidable causes of childhood blindness caused most congenital eye anomalies. Intensification of community-based health promotion and preventive eye care, early detection and provision of adequate resources for effective therapy could reverse ...
The iris of the eye changing color can be a sign that the cells in the eye are being damaged. This may be caused by nerve tissue tumors, neurofibromatosis, iris melanomas, or Waardenburg syndrome.. If you notice any of these eye abnormalities, they could be a warning sign of a severe issue. Talk to your doctor as soon as possible to get prompt treatment.. ...

Axenfeld-Rieger syndrome (ARS) is associated with mutations in the PITX2 gene that encodes a homeobox transcription factor. Several intronic PITX2 mutations have been reported in Axenfeld-Rieger patients but their effects on gene expression have not been tested. We present two new families with recurrent PITX2 intronic mutations and use PITX2c minigenes and transfected cells to address the hypothesis that intronic mutations effect RNA splicing. Three PITX2 mutations have been analyzed: a G|T mutation within the AG 3 splice site (ss) junction associated with exon 4 (IVS4-1G|T), a G|C mutation at position +5 of the 5 (ss) of exon 4 (IVS4+5G|C), and a previously reported A|G substitution at position -11 of 3ss of exon 5 (IVS5-11A|G). Mutation IVS4+5G|C showed 71% retention of the intron between exons 4 and 5, and poorly expressed protein. Wild-type protein levels were proportionally expressed from correctly spliced mRNA. The G|T mutation within the exon 4 AG 3ss junction shifted splicing exclusively to
Heres another thing about my eyes that are weird: I see different colors out of each eye. Its actually very subtle and I noticed it when I was about 12 or 13.

eye examinations should be universal in all infants suspected of antenatal Zika virus infection because early interventions might improve long-term outcomes.
Silver (taffy) coat colours include the eye-catching black silver (aka silver dapple) and bay silver.. The silver gene alters the distribution of black pigment but does not affect red. This means that the effect of the silver gene is not visible on chestnut horses and other colours that have no black, such as palomino.. In addition to its effect on colour the silver gene is thought to cause eye abnormalities in some silver horses (not all). These are referred to as multiple congenital ocular abnormalities (MCOA). These abnormalities can affect vision. Horses with two copies of the silver gene are substantially more likely to show signs of MCOA than those with one copy of the gene. ...
Collie eye anomaly is a disease of the eye that affects more than just collies. Learn what this disease is and what breeds are at risk.
Die Collie Eye Anomaly (CEA) ist eine komplexe, das Auge betreffende Erbkrankheit, die von eine regionalen Hypoplasie der Choroidea, der hoch vaskularisierten Schicht des Auges, welche die Retina mit Blut und Nährstoffen versorgt, charakterisiert wird. Mitunter lassen sich auch gewundene Retinagefäße und mehrfache Faltungen der Retina beobachten. Die klinischen Symptome können stark zwischen betroffenen Hunden innerhalb einer Rasse, zwischen Elterntieren und Nachkommen sowie innerhalb eines Wurfes variieren. Keine medizinische Behandlung der Krankheit ist verfügbar.. CEA ist unter Hunden mit einer Häufigkeit von 65 bis 97 % bei Langhaar- und Kurzhaarcollies weit verbreitet, wobei die Häufigkeit bei Border Collies geringer ist. CEA tritt außerdem bei Hirtenhunden oder Rassen auf, die von klassischen Hirtenrassen abstammen.. Die Vererbung von CEA ist autosomal-rezessiv bei variabler Expression und Pleomorphismus (große Bandbreite in der klinischen Expression der Störung). Einige schwach ...

Semantic Scholar extracted view of Morphogenetic study of congenital ocular malformations in rats, induced by excessive vitamin A, with special reference to exophthalmos. by Takami Miki
ARS presents with ocular features (eye abnormalities) and non-ocular features. Most commonly affected ocular structure in ARS are the iris, the cornea, and the anterior chamber. The ocular abnormalities often affect both eyes, although it can be asymmetrical and in rare cases, only one eye might be affected.. The iris abnormalities include underdevelopment (iris hypoplasia) or thinning of the iris (iris stromal atrophy). In more severe cases, this may result in the formation of holes in the iris that can appear as if the individual has more than one pupil (pseudopolycoria). Iris hypoplasia may also lead to the displacement of the pupil from its normal position (corectopia). If severe, iris hypoplasia may even appear as aniridia, the complete absence of the iris. Less commonly, ARS may present with strabismus, a condition where the two eyes are misaligned with each other. This is because the extraocular muscles which are responsible for eye movements attach to the eye at abnormal insertion ...
Exposure of pregnant rats to inhalation of nickel carbonyl on days 7 or 8 of gestation frequently causes the progeny to develop ocular anomalies, including anophthalmia and microphthalmia. The incidence of extraocular anomalies is very low. The specificity of nickel carbonyl for induction of ocular anomalies in rats appears to be unique among known teratogenic agents. ...
Pitx2 is a homeodomain transcription factor that is mutated in Rieger syndrome, a haploinsufficiency disorder affecting eyes and teeth. Pitx2 also has a postulated role in left-right axis determination. We assessed the requirements for Pitx2 directly by generating hypomorphic and null alleles. Heterozygotes for either allele have eye abnormalities consistent with Rieger syndrome. The ventral body wall fails to close in embryos homozygous for the null allele, leaving the heart and abdominal organs externalized and the body axis contorted. In homozygotes for either allele, the heart tube undergoes normal, rightward looping and the stomach is positioned normally. In contrast, homozygotes for both alleles exhibit right isomerization of the lungs. Thus, Pitx2 is required for left-right asymmetry of the lungs but not other organs. Homozygotes for either allele exhibit septal and valve defects, and null homozygotes have a single atrium proving that a threshold level of Pitx2 is required for normal ...
There have been reports of eye abnormalities detected on MRI exams of COVID-19 patients, but theres only been limited investigation into the types and rates of such eye problems.. To learn more, the French Society of Neuroradiology conducted a study of 129 patients with severe COVID-19 who underwent brain MRIs.. Nine (7%) of the patients had one or more nodules in the back part of the eyeball. All had nodules in the macular region, and eight had nodules in both eyes. Eight of the nine patients had COVID-19 so severe that they had to spend time in ICUs.. The new findings were published Feb. 16 in the journal Radiology.. This is the first time these findings have been described using MRI, Lecler noted in a journal news release.. The researcher said that severe eye problems might be missed in COVID-19 patients in hospital ICUs because theyre often being treated for much more severe life-threatening conditions.. Our study advocates for screening of all patients hospitalized in the ICU for ...
Fig. 6. CX-4945 rescues neurological and phenotypic defects in an mnb-overexpressing Drosophila model. (A) The eyes of adult flies overexpressing mnb and/or human Tau under the control of the eye-specific GMR-Gal4 driver, and of control flies bearing only GMR-Gal4. Overexpression of mnb aggravated the eye abnormality induced by Tau overexpression. This eye defect was effectively rescued by feeding with 100 nM of CX-4945. White dashed lines outline the eye contour. (B) The retinal surface areas were measured on multiple samples (n,10) from each genotype, and average eye sizes were presented as normalized percentages of the DMSO-treated GMR-Gal4 control.

Learn about eye abnormalities in inbred C57 black mice. Ophthalmic abnormalities such as Microphthalmia and anophthalmia can often lead to ocular infections in mice.
In any transgenic mice, insertion of the transgene in the genome is potentially mutagenic. It has been proposed that about 5-10% of transgenic mice harbour transgene induced chromosomal alterations, including deletions and translocations.7,8 Thus, random insertion of foreign DNA into any genome is liable to deactivate or activate one or more genes. The striking eye phenotype observed in the T27aT15 transgenic line seems to be the result of the transgene insertion into the genome as the phenotype is unique among more than twenty transgenic lines that were generated using identical or similar constructs.3. We present a phenotypic characterisation of the T27aT15 line. A proportion of hemizygous transgenic mice developed serious abnormalities of the eye, usually starting between one and two months of age. The progressive eye abnormalities seem to arise after eye formation, as the eye appears to develop normally. The phenotype of these mice includes corneal opacity, cataract, and retinal vascular ...
Mutations in the |i|COL4A3|/i| gene are frequently reported to be associated with various types of hereditary nephropathy. |i|COL4A3|/i| encodes the |i|α|/i|3 chain of type IV collagen, which is the main structural protein in the basement membrane. Mutations in this gene are always related to kidney performance, and deafness and ocular lesion have also been reported. In this study, using next-generation sequencing, we investigated the DNA of a family visiting a clinic for hearing loss. A new missense mutation was found in |i|COL4A3|/i| of 5 patients, c.3227C>T (p.P1076L). Based on these results, we predict that the mutation is pathogenic and leads to abnormal collagen IV. Here, we report for the first time on this autosomal dominant syndrome, characterized by hearing loss and eye abnormalities, but without renal damage, in all carriers. Since the oldest patient in the trial was less than 50 years old, however, we recommend that renal examination be reviewed regularly. Our results reveal

[more ▼]. Pax6 is a well conserved transcription factor that contains two DNA-binding domains, a paired domain and a homeodomain, and plays a key role in the development of eye, brain, and pancreas in vertebrates. The recent identification of the zebrafish sunrise mutant, harboring a mutation in the pax6b homeobox and presenting eye abnormalities but no obvious pancreatic defects, raised a question about the role of pax6b in zebrafish pancreas. We show here that pax6b does play an essential role in pancreatic endocrine cell differentiation, as revealed by the phenotype of a novel zebrafish pax6b null mutant and of embryos injected with pax6b morpholinos. Pax6b-depleted embryos have almost no beta cells, a strongly reduced number ...
The Zika virus is prompting great concern because of a disturbing connection to a neurological birth disorder and its rapid spread across the globe. Transmitted by mosquitos, the virus has been linked to a rare birth defect called microcephaly, which causes babies to have small heads and incomplete brain development. Now a new study published in the journal JAMA suggests the Zika virus may also cause eye abnormalities in newborns. Here is an ophthalmologists insights on the mosquito-borne virus and its potential impact on vision.. Babies born with microcephaly often have developmental issues, as well as hearing and vision problems, explained Sandy T. Feldman, MD, the Medical Director of Clearview Eye & Laser Medical Center in San Diego and one the nations top ophthalmologists. Whats curious about the JAMA study is that more than a third of the babies tested showed signs of scarring on the optical nerve, which can cause progressive vision loss. Researchers suspect these ocular lesions were ...

In findings from what officials call the largest systematic tracking of pregnancies among women with laboratory evidence and confirmation of Zika virus, the U.S. Centers for Disease Control and Prevention released data Tuesday showing that one in 10 women with confirmed infection while pregnant had babies or fetuses with birth defects that have been linked to the disease, including microcephaly, eye abnormalities and spinal malformations. The data represents outcomes of 972 pregnancies, ending in either birth or miscarriage, of women with laboratory evidence of recent Zika infection, in 250 of whom Zika infection was confirmed in further laboratory testing. Birth defects were reported in 51, or 5 percent, of the infants or fetuses resulting from the total number of completed pregnancies in women with evidence of infection, and in 24, or 10 percent, of infants or fetuses whose mothers were confirmed to have recent infection. The data represents the pregnancy outcomes of women tracked by the ...

New experimental and theoretical findings on eyes and the dynamics of eyesight can help to explain the origin of severe eye diseases and could lead to new ways of preventing blindness.
This intronless gene encodes a member of the SRY-related HMG-box (SOX) family of transcription factors involved in the regulation of embryonic development and in the determination of cell fate. The product of this gene is required for stem-cell maintenance in the central nervous system, and also regulates gene expression in the stomach. Mutations in this gene have been associated with optic nerve hypoplasia and with syndromic microphthalmia, a severe form of structural eye malformation. This gene lies within an intron of another gene called SOX2 overlapping transcript (SOX2OT). [provided by RefSeq, Jul 2008 ...
