Objective To investigate the clinical features of multifocal choroiditis (MC) and guide the diagnosis and treatment. Methods Retrospective analysis of clinical data of 18 MC cases (28 eyes) who were diagnosed through fluorescein angiography (FFA) or indocyanine green angiography (ICGA) and fundus characteristics. Results Multiple round to oval lesions scattered throughout the posterior pole and peripheral areas of ocular fundi of all of the 28 eyes(binocular in 10 and monocular in 8) were found. Active focal lesions of ocular fundi were seen in 8 patients and inactive lesions in 10 patients. active and 10 cases were inactive. Choroidal neovascularization(CNV) in macular area was found in 7 patients. The images of FFA of the legions showed hypofluorescence in the early phase, with late leakage and gradual staining or window is defect in the late phase. Conclusions MC is a rare disease and often misdiagnosed to other disease and FFA helpful in diagnosis. (Chin J Ocul Fundus Dis, 2005, 21: 367-370)
Objective To observe the characteristics of spectral-domain optical coherence tomography (SD-OCT) for leakage point in acute central serous chorioretinopathy (CSC). Methods A total of 21 acute CSC patients (21 eyes) were enrolled in this retrospective study, including 17 men (17 eyes) and 4 women (5 eyes). The mean age was (47.3±8.8) years (range 35 - 66 years). The mean duration was (1.6±0.8) months (range 0.5 - 3.0 months). All patients were underwent mydriatic fundus photography, SD-OCT examination and fluorescein fundus angiography (FFA). SD-OCT and FFA images were carefully compared to observe the SD-OCT examination characteristics of fluorescence leakage point. Results 21/21 eyes had one fluorescein leakage point. In addition to serous retinal detachment, leakage point in the SD-OCT examination showed retinal pigment epithelium (RPE) protrusion in 10 eyes (47.6％), RPE detachment in 7 eyes (33.3％), highly reflective areas suggesting fibrinous exudate in the subretinal space in 3 eyes (14.3％), and RPE defect in 1 eye (4.8％). Conclusion The SD-OCT characteristics of acute CSC include RPE protrusion, RPE detachment, highly reflective areas suggesting fibrinous exudate in the subretinal space and RPE defect.
ObjectiveTo observe and explore the fundus characteristics and fundus fluorescein angiography of familial exudative vitreoretinopathy (FEVR) in different stages. MethodsA total of 15 patients (23 eyes) diagnosed as FEVR in the West China Hospital of Sichuan University from January 2007 to November 2013 were included. Clinical data and reports of fundus exams and fundus fluorescein angiography (FFA) were retrospectively analyzed. ResultsOne eye (4.35%) was classified as stage Ⅰ, 10 eyes (43.48%) were classified as stage Ⅱ, 8 eyes (34.78%) were classified as stage Ⅲ, and 1 eye (4.35%) and 3 eyes (13.04%) were classified as stage Ⅳ and V, respectively. The outcomes of fundus exams showed that the number of peripheral retinal blood vessels increased, and vessels straightened as well as narrowed, especially in the temporal area. FFA showed blood vessels suddenly shut in the equatorial retina and peripheral non-perfusion areas were observed. ConclusionTypical fundus characteristics and fundus fluorescein angiography changes of FEVR can be observed in different stages. Comprehensive fundus exams and family history are helpful to confirm relevant diagnosis.
Objective To observe the manifestation of fundus angiographs of polypoidal choroidal vasculopathy (PCV). Methods Twelve PCV patients involved 7 males and 5 females aging from 40 to 69 year old (average 56.4). Fundus examination, fundus fluorescein angiography (FFA), and indocyanine green angiography (ICGA) were performed on 12 patients (12 eyes) with PCV, out of whom 5 underwent optical coherenece tomography (OCT). Results In 12 eyes, deep and (or) superficial hemorrhage and yellow hard exudations were found, including orange-red lesions in 6 and pre-retinal hemorrhage in 2. The results of FFA discovered orange-red spotty fluorescence in 6 eyes and choroidal vascular network in 4 eyes. At the late phase, leakage of polypoidal hyperfluorescence spot in all of the eyes except 2 without leakage were found. The images of ICGA showed typical dotted or clustered polypoidal hyperfluorescence in 12 eyes at the late phase. OCT disclosed protrusion of the retinal pigment epitelium (RPE) with a bumpy surface at polypoidal structure in 4 eyes and no change in 1 eye. Conclusions PCV mainly affects the elderly persons and mostly on unilateral eyes. Macular hemorrhage,serous RPED, and (or) neuroepithelial detachment with yellow hard exudations are the main manifestations. Branching choroidal vascular net with ployplike terminal anourysmal dilations can be discovered in FFA and ICGA. (Chin J Ocul Fundus Dis，2004，20：310-312)
Objective To explore the clinical manifestations and the characteristics of images of indocyanine green angiography (ICGA) and fundus fluorescein a ngiography(FFA) of multifocal choroiditis. Methods Eight patie nts (10 eyes) with multifocal choroiditis were gathered. The clinical manifestations and the images of ICGA and FFA were analyzed. Results Foci of multifocal choroiditis were found in posterior pole and peripheral areas of ocular fundi of all of the 10 eyes. The images of ICGA revealed hypofluorescence in focal area. The images of FFA showed hypofluorescence at the early phase and fluorescein leakage at the late phase in the active focus, and fluorescein staining and window defect fluor escence in the inactive focus. Conclusions The clinical manife stations of multifocal choroiditis varied with disease course, location and numbers of the lesions. ICGA and FFA can show the development of the disease clearly, which may guide the treatment. (Chin J Ocul Fundus Dis，2004，20：87-89)
