Fast and efficient high-throughput techniques are essential for the molecular diagnosis of highly heterogeneous hereditary diseases, such as retinitis pigmentosa (RP). We had previously approached RP genetic testing by devising a chip based on co-segregation analysis for the autosomal recessive forms. In this study, we aimed to design a diagnostic tool for(More)
PURPOSE To identify the genetic basis of a large consanguineous Spanish pedigree affected with autosomal recessive retinitis pigmentosa (arRP) with premature macular atrophy and myopia. METHODS After a high-throughput cosegregation gene chip was used to exclude all known RP and Leber congenital amaurosis (LCA) candidates, genome-wide screening and linkage(More)
PURPOSE A large family with 11 males and 2 females with X-linked retinitis pigmentosa (XLRP) was analyzed in search of pathologic mutations. METHODS Of the two major XLRP genes, RPGR was analyzed by SNP cosegregation and RP2 was directly screened for mutations. The pathogenicity of a new variant was assessed in silico, in vivo, and in vitro. RESULTS The(More)
UNLABELLED INTRODUCTION Laser-assisted in situ keratomileusis surgery may induce postoperative changes in the vitreomacular interface due to the mechanical stretch of the vitreous produced by the suction ring and the shock waves generated by the excimer laser and, subsequently, may provoke macular hole formation. CASE PRESENTATION A 53-year-old Spanish(More)
PURPOSE To compare the effectiveness, efficiency and complications of three different surgical techniques employed for the treatment of macular holes between 1998 -2004 in our health care centre. METHODS A retrospective, comparative, and non-randomized study of 131 eyes with macular holes, stage III and IV, treated with three different surgical techniques(More)
CLINICAL CASE A 32-year-old male, with colon cancer stage IV, resistant to chemotherapy, was referred to our department due to palpebral oedema, conjunctival chemosis, severe exophthalmos, complete ptosis in left eye, and limitation in eye movements, mainly in abduction and supraversion. In the orbital MR scan we observed two nodular lesions in the left(More)
INTRODUCTION Several macular complications related to abnormalities of the vitreoretinal interface have been classically attributed to retinitis pigmentosa of which cystoid macular edema is the most common. Other less frequent complications are as follows: epiretinal membranes, vitreomacular traction syndrome and macular holes. CASE PRESENTATION A(More)
