PURPOSE To report an unusual case of central serous chorioretinopathy (CSC), presenting as bilateral and multifocal isolated serous retinal pigment epithelium detachments (RPEDs) following corticosteroid treatment. METHODS An otherwise healthy 39-year-old man was evaluated for visual loss following blunt trauma of his right eye (RE). The patient underwent complete bilateral ophthalmologic exa...
BACKGROUND To describe the clinical manifestations and ancillary examination outcomes of ocular syphilis in Southeast China. MATERIALS AND METHODS This is a retrospective, nonrandom case study. Demographic information, serum and cerebrospinal fluid (CSF) test results, and findings of fundus fluorescein angiography (FFA), indocyanine green angiography (ICGA), and spectral domain optical cohere...
PURPOSE To propose a novel classification system for polypoidal choroidal vasculopathy (PCV), and compare the clinical outcomes among PCV subtypes. METHODS Consecutive treatment-naive patients with symptomatic PCV were managed over 5 years. PCV subtypes were classified based on indocyanine green angiography (ICGA) and fluorescein angiography (FA) characteristics. RESULTS Among 107 patients,...
PURPOSE To determine the proportion of patients with central serous chorioretinopathy (CSCR) mistaken for posterior uveitis and to identify the deleterious consequences. METHODS Charts of 1,657 patients admitted in the section of inflammatory eye diseases at the Center for Ophthalmic Specialized Care (COS) in Lausanne, Switzerland from 1995 to 2013 were reviewed. CSCR cases misdiagnosed as po...
AIM To evaluate the anatomic and functional results of intravitreal ranibizumab injection for treatment of symptomatic retinal arterial macroaneurysm (RAM). MATERIALS AND METHODS A series of seven patients (seven eyes) who had been diagnosed with symptomatic RAM were assessed by comprehensive ophthalmologic examination, fluorescein angiography (FA), optical coherence tomography (OCT), and ind...
AIMS To determine the prevalence of polypoidal choroidal vasculopathy (PCV) in patients with presumed neovascular age-related macular degeneration (AMD) who were considered poor responders to ranibizumab. METHODS Caucasian patients with suspected neovascular AMD, presumed to be choroidal neovascularisation, previously treated with ≥8 intravitreal injections of ranibizumab 0.5 mg (Lucentis; No...
PURPOSE To determine the efficacy of half-dose photodynamic therapy (PDT) in relation to indocyanine green angiography (ICGA) and optical coherence tomography (OCT) findings for treating chronic central serous chorioretinopathy (CSC). DESIGN Observational case series. METHODS Thirty-eight eyes of 37 patients with chronic CSC and symptoms for at least 6 months were recruited. PDT was perform...
Syphilitic chorioretinitis should be included in differential diagnosis of any form of ocular inflammation. A significantly higher proportion of human immunodeficiency virus (HIV)-positive patients with ocular syphilis as compared to HIV-negative cases have been reported in published studies. However, the clinical signs and symptoms are more insidious in HIV-negative patients who are easily mis...
Microsurgical subinguinal varicocelectomy (MSV) is generally considered the gold standard nowadays in view of the lower risk of complications and recurrence. To achieve complete ligation of veins while preserving testicular artery (TA) during the procedure remains challenging despite the application of high power optical magnification and micro-Doppler ultrasonography. The use of intraoperative...
یک مجموعه k-همبند m-احاطه گر برای بررسی نوسان خطا و پیچیدگی مسیر یابی لازم می باشد. الگوریتم های تقریبی زیادی برای ساختن یک مجموعه k-همبند m-احاطه گر ارائه شده اند اگرچه بیشتر الگوریتم ها حالت های خاصی مانند k=1، k=2 یا k<m را در نظر میگیرند یا قابل اجرا نیستند و یا پیچیدگی پیام بالایی دارند، اما الگوریتم هایی مانند cga، icga و csaa وجود دارند که به ازای k و mهای مختلف قابل اجرا هستند. در این پ...
