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 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 investigate the clinical features, etiological classification and staging of epiretinal macular membrane(MEM)． Methods Clinical materials of 194 cases of MEM diagnosed by fundus fluorescein angiography in outpatient department of eye clinic in this hospital from 1983 to 2000 were retrospectively analyzed． Results There were typical clinical symptoms and signs of MEM in all of this 222 eyes of 194 patients． Etiological classification revealed that 4 cases were congenital(2．12%), 22 cases were secondary(11．34%), and 168 cases were idio pathic(86．60%)． Staging of course of disease indicated that 119 eyes were in early stage(53．60%), 72 eyes were in middle stage(32．43%), and 31 eyes were in late stage(13．96%)． Conclusion MEM may be classified as congenital, secondary and idiopathic type according to its pathogenesis , as early, middle and late stage according to the clinical course of disease．This can be helpful in treating the disease． (Chin J Ocul Fundus Dis, 2001,17:210-213)
Objective To icompare the effects of indocyanine green angiography(ICGA) on ganzfeld Electroretinogram(ERG). Methods ICGA was performed used the Topcon 50IA retina camera, Ganzfeld ERG was recorded by Neuropack Ⅱ evoked response recorder. The Ganzfeld ERG was recorded before and after ICGA in 20 cases (38 e yes) with different diseases , Ganzfeld ERG was recorded according to the ISCEV standard recommendations. Results ICGA did neither affect Ganzfeld ERG a-wave and b-wave latency nor amplitudes of dark adaptation, maximum response and light adaptation.(Pgt;0.05). Conclusion ICGA using the Topcon 50IA could be performed prior to the recording of the Ganzfeld ERG. (Chin J Ocul Fundus Dis, 2001,17:284-285)
