PURPOSE To evaluate the effect of an endocapsular tension ring in preventing zonular complications during phacoemulsification of cataracts associated with pseudoexfoliation syndrome. SETTING Eye Clinic of Beyoğlu Education and Research Hospital, Istanbul, Turkey. METHODS A prospective randomized study comprised 78 eyes with cataract and pseudoexfoliation syndrome that were randomly divided ...

Pseudoexfoliation syndrome is characterised by the production and progressive accumulation of fibrillar extracellular material within different ocular tissues, and its incidence varies considerably according to geographical location. Cataract surgery in pseudoexfoliative patients is associated with a higher rate of complications, which are more common the more advanced the cataract. For this re...

Surgical management of ectopia lentis is one of the major challenges faced by cataract surgeons today. Ectopia lentis signifies a displacement or malposition of the crystalline lens, irrespective of cause. It may occur congenitally or as part of developmental anomalies, as found in Marfan syndrome, homocystinuria, Ehlers-Danlos syndrome, hyperlysinemia, sulfite oxidase deficiency, simple primar...

BACKGROUND Current recommendations for ANCA-associated vasculitis (AAV) support its management within a dedicated clinical service. Therapies for AAV are imperfect with many patients failing to achieve disease control and others experiencing disease relapse. Plasma exchange (PEX) may be beneficial especially when the kidney is involved. METHODS Within a new, dedicated service we retrospective...

PEX, a phosphate-regulating gene with homology to endopeptidases on the X chromosome, was recently identified as the candidate gene for X-linked hypophosphatemia. In the present study, we cloned mouse and human Pex/PEX cDNAs encoding part of the 5' untranslated region, the protein coding region, and the entire 3' untranslated region, determined the tissue distribution of Pex/PEX mRNA, and chara...

purpose: to determine hearing thresholds at sound frequencies important for speech comprehension in subjects with ocular pseudoexfoliation (pxf) and to compare them with that of controls without pxf. methods: eighty-three subjects with ocular pxf and 83 age and sex matched controls without pxf were enrolled in this case-control study. pure tone audiometry (bone conduction) was performed at 1, 2...
