Abstract
I study was registered at http://www.clinicaltrials.gov (NCT00478530). RESULTS All patients showed significant improvements in peripheral visual field (mean deviation improved from -4.77+/-2.0 to -3.28+/-2.28, p=0.009, t test) and a highly significant improvement in rod recovery rates measured elect...

Abstract
Mitochondria are critical for ocular function as they represent the major source of a cell's supply of energy and play an important role in cell differentiation and survival. Mitochondrial dysfunction can occur as a result of inherited mitochondrial mutations (e.g. Leber's hereditary optic neuropath...

Abstract
Entry into the genetic testing system often is via the patient's ophthalmologist. Collaboration with geneticists and genetic counselors, use of web sites to keep up with the ever-changing availability and detection rates, and knowledge of clinical trials, when combined with excellent clinical diagno...

Abstract
The main clinical manifestations of pseudoxanthoma elasticum (PXE) alter small arteries, the eyes and the skin. At the microanatomical level, the feature in common is an alteration of the elastic fibres that appear dystrophic and in part calcified. The disease is genetically transmitted as an autoso...

Abstract
Pseudoxanthoma elasticum is a heritable connective-tissue disorder affecting the eye, skin, and vascular system. The aim of our study was to specify the epidemiological and clinical characteristics of this disease in a hospital series. A total of 22 patients were included during a period of 19 years...

Abstract
We report on a clinical and genetic investigation of CACD in a large Tunisian consanguineous family with 21 affected individuals in three living generations. CACD has been associated with drusen in some of them. Linkage analysis and mutational screening exclude linkage to the PRPH2/RDS gene and to t...

Abstract
Recently, preliminary results of three clinical gene therapy trials for early onset retinitis pigmentosa--Leber congenital amaurosis--suggested that treating this degenerative retinal disease by gene transfection can be safe and efficient to restore a visual function. The definitive validation of th...

Abstract
COL18A1 mutations involved in Knobloch syndrome have a distribution bias toward the coding exons of the C-terminal end. Large deletions must also be considered when point mutations are not identified in patients with characteristic KS phenotype. We report, for the first time, lack of type XVIII coll...

Abstract
We have taken advantage of the ability of aminoglycoside drugs to suppress such nonsense mutations and partially restore full-length, functional protein in a zebrafish model of choroideraemia (chm(ru848); juvenile chorio-retinal degeneration) and in two models of ocular coloboma (noi(tu29a) and gup(...

Abstract
Presence or absence of family history is not associated with more severe clinical disease, at least when each marker for severity is considered independently. The results of this analysis are important for genetic studies of keratoconus in that it will allow recruitment of keratoconus patients acros...

Abstract
We report a case of KNO confirmed by direct sequence analysis of the COL18A1 gene with typical ocular features, and previously unreported systemic features: occipital hair tuft with transient CSF leak and bilateral renal abnormalities. This case illustrates a new phenotypic variant of this syndrome....

Abstract
We recently found mutations in a novel gene FRMD7 (Xq26.2), which provided an opportunity to investigate a genetically defined and homogeneous group of patients with nystagmus. We compared clinical features and eye movement recordings of 90 subjects with mutation in the gene (FRMD7 group) to 48 subj...

Abstract
Gene therapy represents a promising therapeutic option for many inherited and acquired retinal diseases. Recombinant adeno-associated viral vectors (AAV) are the most efficient tools to transfer genes in vivo to the retina. The recent identification of dozens of novel AAV serotypes enormously expand...

Forty-five patients were diagnosed as NCMD; all six NCMD families were mapped to MCDR1 locus using genetic linkage analysis. MCDR1 interval was refined to 3 cM (1...

Abstract
We describe here two mutations in exon 2 of COL2A1 in three patients with predominantly ocular Stickler syndrome: Cys64Stop in two patients, and a novel structural mutation, Cys57Tyr, in one patient. RT-PCR of total lymphoblast RNA from one patient with the Cys64Stop mutation revealed that only the...

Abstract
L-carnitine plays a role in physiological reactions throughout the body, including sugar aerobic metabolism, oxidative phosphorylation and, most importantly, fatty acid oxidation. In addition, L-carnitine has antiapoptotic, antioxidative and osmolytic properties, which may be useful in the treatment...

We report the first clinical case of FEVR associated with hyaloid artery persistence. An 18-year-old Tunisian woman and four members of her family (mother, two brothers, and sister) presented signs of FEVR. Examination of this patient also revealed functional hyaloid artery persistence in her right...

Abstract
We previously found that the ATP content in UPL rat lenses decreases during cataract development, and the decrease in ATP content causes Ca(2+)-ATPase dysfunction resulting in an elevation in Ca(2+) and cataract development. In addition, we reported that the oral administration of disulfiram and ami...

Abstract
We investigated the involvement of interleukin (IL)-18, which leads to interferon-gamma, in UPL rat lenses. The opacification of UPL rat lenses starts at 39 days of age. The gene expression levels causing IL-18 activation (IL-18, IL-18 receptor and caspase-1) are increased at 32 days of age, and the...

We are to do so by studying cases of CCO. Peters' anomaly is too imprecise a term to describe cases of CCO. This classification of primary and secondary CCO with its subclassifications cannot be made by clinical examination alone and necessitates other diagnostic assessments. It is time to only acce...

Abstract
We mapped this disorder to chromosome 2q23.3-31.1 and identified LRP2 mutations in six families with Donnai-Barrow syndrome and one family with facio-oculo-acoustico-renal syndrome. LRP2 encodes megalin, a multiligand uptake receptor that regulates levels of diverse circulating compounds. This work...
