Causes And Frequency Of The Fundus Diseases In Patients Receiving FFA In West China Hospital

Objcetives: To estimate the anatomical sites affected, etiopathogenisis andsingle causive conditions of the ocular fundus diseases by age and gender in patients receiving fundus fluorescein angiography (FFA) in West China Hospital.Methods: A retrospective study of patients who visited the ophthalmologydepartment of West China Hospital and receiving FFA during 2004 and 2005 was performed. Analysis the data by anatomical site affected, etiopathogenisis, single causive condition, age and gender of the patients.Results: A total of 3026 patients' records were analysed, the mean age was50.4 years (SD16.9; range, 4～91 years), 53.4% male. 97.8% of the patients were above 14 years.The most frequently affected site was the retina, accouting for 89.3% of the patients. The retinal vascular diseases and diseases causing choroidal neovascularization were the most important groups of diseases that could lead to similar pathologic sequelae respectively. The leading single causive condition of this population was diabetic retinopathy (DR), followed by retinal venous occlusions (RVO), central serous chorioretinopathy (CSC), age-related macular degeneration (AMD) , macular degeneration of high myopia, and retinal vasculitis (RV), which accounted for 69.0% of the patients. The most frequent diseases in children(～14 years) were Coats disease(21.2%), Stargardt disease(12.1%) and morning glory disc anomaly(9.4%); In youth (15～44 years), they were CSC(23.1%) and RV(14.0%); In the middle-aged(45～59 years), they were DR(30.1%) and RVO(26.4%); In patients of old age (60 years and older), DR(32.8%), RVO(26.2%) and AMD(12.7%) were the leading diseases, AMD(40%) was most common among patients aged 75 or older.Conclusions: The retinal vascular diseases and diseases causingchoroidal neovascularization were the most common and important diseases in the study population, which were most frequently seen in the middle-aged and the elderly people. People who were suspected of these diseases should do the FFA examination to guide the treatment and preserve vision.
