هدف: این مطالعه به منظور بررسی میزان فراوانی بیماری lebers congenital amaurosis در تست های الکتروفیزیولوژیک در کودکان در پلی کلینیک قدس سال 90-89 انجام شده است. روش مطالعه: در این مطالعه مقطعی، 50 فرد بدون وجود سابقه اختلال بینایی و تشنج وارد مطالعه شدند شامل 25 نفر مبتلا به lebers congenital amaurosis و 25 نفر که سالم و بعنوان گروه شاهد بودند. دو گروه تحت erg و vep و eog قرار گرفتند و نتایج ب...
Retinitis pigmentosa (RP) is the generic name for a group of hereditary disorders characterized by progressive loss of photoreceptors and RPE function. The classical triad of retinitis pigmentosa is arteriolar attenuation, retinal bone spicule pigmentation and waxy disc pallor. Lebers congenital amaurosis (LCA) is the hereditary form of retinitis pigmentosa. It presents with blindness either at...
purpose : to evaluate the incidence of leber’s congenital amaurosis (lca) in low vision children referred to electrophysiology ward of farabi eye hospital , and review the clinical features of disease and electroretiongraphy (erg) test values to confirm the diagnosis and severity of the disease in iran . design: prospective observational case series methods : two-hundred and fifteen cases of lo...

Invest Ophthalmol Vis Sci. 2014;55:6817–6828. DOI: 10.1167/iovs.14-14923 PURPOSE. To characterize visual losses associated with genetic mutations in the RPE65 gene that cause defects in the RPE-specific isomerase, RPE65. RPE65 is an im...
PURPOSE To determine whether pathogenic mutations exist in the ELOVL4 gene in patients with inherited retinal degenerations other than Stargardt-like macular dystrophy or other hereditary macular degenerations. METHODS All six exons comprising the open reading frame of the ELOVL4 gene were evaluated by single-strand conformation analysis, direct nucleotide sequencing, or both methods. RESUL...
rig. renpheralfundus cS. We have had occasion to see a similar case, first in 1974 when the patient, a black female with no apparent vision but otherwise well, was 6 months old. At that time dilated fundus examination under anaesthesia (EUA) was normal. Repeat EUA in 1977 at age 4 years revealed bilateral peripheral fundus lesions essentially identical to those described by Chew et al. (Figs. 1...
