Objective To observe the clinical manifestations and feat ures of fundus fluorescein angiograms(FFA)of patients with multifocal choroiditis (MFC)MethodThe data of 8 patients who had been diagnosed by clinic and FFA as with MFC were collected, and their clinical manifestatio ns and results of FFA were analyzed and valued.ResultsThe age of the 7 female and 1 male patients ranged from 16 to 32, and all of the 8 patients had high myopia (from -6.00 D to -8.00 D) with binocular multiple small yellowish white lesions in posterior pole of the fundus and a few phlogistic ce lls in vitreous body. In addition, macular choroidal neovascularization membrane (CNV) was found in 6 patients, binocular in 2 and monocular in 4. The results of FFA in 7 patients showed hypofluorescence of the yellowish white lesions at t he early phase and pigmentation at the late phase; Corresponding manifestations of FFA could be found in the patients attended by CNV surrounded by leakage.ConclusionMFC are mostly diagnosed in young females with myopia. Most of the patients had binocular affection with multiple small yellowish white lesions at the posterior pole, whose FFA shows hypofluoresence of the active lesions at the early phase and pigmentation at the late phase. CNV may occur in patients with MFC.(Chin J Ocul Fundus Dis，2004，20：335－338)
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 discuss the image of indocyanine green angiography (ICGA) about high myopia． Methods Tweenty-seven patients (54 eyes) with high myopia underwent ocular examination, funduscolorphotography, simultaneous ICGA and fluorescein angiograp hy (FFA) with theconfocalscanning laser ophthalmoscope．The findings for the two modes of amgiographies were compared． Results Lacquer crack was evident on ICGA in 19 eyes among which the focal, plaque choroidal neovascularization (CNV) were apparent in the middle part of lacquer cracks in 10 eyes (52．6%) ．In comparison the lacquer cracks were seen in only 7 eyes on FFA． Choroidal capillary atrophy was seen on ICGA and FFA in 14 eyes and ICGA shew thick choroidal vessels in 3 eyes． Conclusion ICGA is superior to FFA for showing choroidoretinal degeneration and atrophy,lacquer crack and CNV in high myopic eyes, and conduce to evaluating prognosis． (Chin J Ocul Fundus Dis, 2001,17:201-203
Objective To compare the characteristics of the results of fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA) in patients with classic choroidal neovasculazation (CNV). Methods The data of FFA and ICGA of 34 patients (36 eyes) with classic CNV were analyzed retrospectively and the results of the two examinations were analyzed contrastively. Results The results of FFA revealed the clew or cartheel-tike configuration of classic CNV at the early phase in 3 out of 15 eyes (20%) with age-related macular degeneration (AMD); in 5 out of 7 eyes with pathological myopia(71.4%); and in 9 out of 14 eyes with central exudative chorioretinopathy (CEC),(64.3%),In 36 eyes with classic CNV, the images of ICGA indicated CNV distinctly in 20 (55.6%) and indistinctly in 15 (41.6%); CNV was not detected by ICGA in 1 eye (2.8%); feeding blood vessels in 6 eyes (16.7%) were detected by ICGA but none by FFA. Conclusions At the early phase of FFA, the configuration of classic CNV is clew-like in eyes with pathological myopia and CEC, and erose in eyes with AMD. The image of ICGA which indicated the outline of classic CNV is not as clear as the one of FFA, but it can reveal the feeding vessels which FFA can not. (Chin J Ocul Fundus Dis, 2006, 22: 217-209)
