Spectral domain OCT versus time domain OCT in the evaluation of macular features related to wet age-related macular degeneration
BACKGROUND The aim of this study was to compare the agreement between spectral domain optical coherence tomography (SD OCT) and time domain stratus OCT (TD OCT) in evaluating macular morphology alterations in wet age-related macular degeneration (AMD). METHODS This retrospective study was performed on 77 eyes of 77 patients with primary or recurring subfoveal choroidal neovascularization seco...

amd بیماری تحلیل شبکیه است که عامل اصلی کوری در افراد بالای 55 سال در جهان غرب به شمار می-رود. در اثر این بیماری، لیپوپروتئین ها در شبکیه تجمع پیدا کرده و رگ زایی القاء می شود. ثابت شده است که عوامل ژنوتوکسیک محیطی مثل سیگار کشیدن، رژیم غذایی و نور در افراد پیر با زمینه ی ژنتیکی مستعد در بروز بیماری دخیل می باشند. بنابراین ما یک مطالعه ی مـورد- شاهـدی را ترتیب دادیم که شـامل 112 فرد مبتلا به am...
the genetics of age-related macular degeneration
age-related macular degeneration (amd) is the leading cause of blindness in old subjects. it is a multifactorial disease with both environmental and genetic factors playing some role in its pathogenesis. similar to many other genetic diseases, the inheritance pattern of amd does not fit into simple mendelian rules. these diseases are caused by the presence of multiple genetic factors and are ca...
متن کاملMeasurement of Choroidal Neovascular Area in Age-Related Macular Degeneration using Modified Otsu’s Thresholding Method
Introduction: Age-related Macular Degeneration (AMD) is one of the most important causes of irreversible blindness in the developed world and prevents the affected person from performing simple tasks such as reading, driving and facial recognition. In the AMD, new blood vessels grow underneath the retina in a process called choroidal neovascularisation (CNV). There ...
متن کاملReproducibility of macular thickness measurements using Cirrus SD-OCT in neovascular age-related macular degeneration.
PURPOSE To assess the test-retest variability of central and sectorial macular thickness measurements obtained by Cirrus HD-OCT (Carl Zeiss Meditec, Dublin, CA) in neovascular age-related macular degeneration (nAMD). METHODS Macular thickness measurements of nine standard ETDRS subfields were obtained and analyzed. The repeatability of macular thickness measurements by Cirrus HD-OCT was asses...
