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)
Purpose To study choroidal vascular abnormal characteristics in choroidal vascular abnormal characteristics in choroiditis using indocyanine green angiography(ICGA). Methods Thirteen cases (16 eyes) of choroiditis were examined with fundus fluorescein angiography (FFA) and ICGA. Results ICGA findings in choroiditis were as follows:(1) dilatation of choroidal vessels with segmentary appearance and irregular margind;(2) hyperpermeability of choroidal vessels;(3) choroidal filling defects; (4) choroidal hypofluorescence with edema;(5) dilatation of vortex veins. (Chin J Ocul Fundus Dis,1998,14:92-84) Conclusion ICGA is useful in evaluating the lesions and circulation disturbance of choroiditis which cannot usually be demonstrable in FFA.
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)
ObjectiveTo observe the clinical evolution process and imaging characteristics of choroidal lesions in different subtypes of serpiginous choroiditis (SC), and to explore the clinical significance of subtype classification. MethodsA retrospective, uncontrolled and observational study. A total of 45 eyes of 25 SC patients diagnosed in Yunnan Eye Hospital from May 2009 to September 2021 were included in the study. According to the initial location of the lesion and fundus images, including fundus color photography, fundus fluorescein angiography (FFA), optical coherence tomography (OCT) and other examination results. SC was divided into peripapillary serpiginous choroiditis, macular serpiginous choroiditis and ampiginous choroiditis. According to the shape of the lesions at the first diagnosis, it can be divided into new lesions with only infiltrating edema, old lesions with only atrophy and recurrent lesions with coexistence of edema and atrophy. the imaging features, development and complications of different subtypes of ocular lesion were observed. ResultsAmong the 45 eyes of 25 cases, 15 cases were male and 10 cases were female, 20 cases of binocular and 5 cases of monocular, age was 42.3±5.7 years old. There were 21 eyes with active lesions, of which 5 eyes were new lesions and 16 eyes with recurrent lesions; 24 eyes were old lesions. Concurrent optic disc edema occurred in 3 eyes; mild vitreitis occurred in 5 eyes; retinal occurred vasculitis in 3 eyes; choroidal neovascularization occurred in 3 eyes. Among the 16 cases (64%, 16/25) of the peripapillary serpiginous choroiditis, 2 cases (2 eyes) were monocular, and 14 cases (28 eyes) were binocular. Active lesions were found in 16 eyes, of which patients with binocular lesions only one had active lesions. The choroidal lesions that were close to the optic disc or around the optic disc, expanded outwards centrifugally with the prolongation of the disease course, and can progress to the macula. The edge of the lesion was tortuous, with a geographic-like, amoeboid-like and finger-like, polypoid or propeller-like shape. Active lesions in FFA showed weak fluorescence in the early stage and strong fluorescence in the late stage; the old lesions showed weak fluorescence in the early stage and mottled fluorescence in the late stage, and mostly strong fluorescence on the edge. OCT showed thickening of active lesions and thinning of old lesions. Among the 4 cases (16.0%, 4/25) of macular type, 2 cases (2 monocular eyes) had active lesions; 2 cases (4 eyes) had lesion in both eyes, among them, 1 case (2 eyes) had old lesion, and the other case had alternate active lesions. The initial lesions were all located in the off-center of the macula, and most of them were disk-shaped and progressing centrifugally to the periphery. The FFA and OCT imaging findings of the lesions were similar to those of the peridisc type. Among the 5 cases (20.0%, 5/25) of ampiginous choroiditis, 1 case (1 eye) was monocular and 4 cases (8 eyes) were binocular. These lesions were multiple old lesions of varying sizes, gray-white with pigmentation, with clear borders in the posterior pole. Among them 4 eyes have new active lesions appeared near the old lesions. The old lesions showed weak fluorescence with clear borders, and the fluorescein leakage at the late edge formed a strong fluorescence ring; the active lesions showed weak fluorescent spots with blurred edges, and the fluorescence was slightly enhanced in the late stage. In old lesions, atrophy of the photoreceptor layer, RPE and choroid can be seen, and RPE hyperplasia in some areas. ConclusionsSC subtype is a classification of the location of the first lesion, but the characteristics of the repeated attack of this disease can lead to the annihilation of each subtype due to the continuous expansion of the lesion. The phenomenon that the fundus active lesions only occur in one eye that can explain the clinical manifestations of asymmetric morphology of binocular lesions. The characteristics of binocular subtype warn that the predilection site of the healthy eye should be paid attention to.
Serpiginous choroiditis (SC) is infrequent, chronic and posterior uveitis displaying a geographic pattern of choroiditis easy to recur. Studies reveal that the active lesions of inflammatory processes are mainly localized to the choriocapillaris and retinal pigment epithelium cells. SC may manifest with variable features, although a creeping pattern of choroiditis, extending from the juxtapapillary area, with grayish yellow discoloration. Fundus fluorescein angiography, indocyanine green angiography, fundus auto-fluorescence and optical coherence tomography are helpful to diagnose atypical SC. In addition, these image examinations can evaluate the activity and progression of lesion, and detect any complication that might occur. SC is mainly distinguished from multifocal SC related with tuberculosis or virus and etc. Pathogenesis is unclear, an organ-specific autoimmune inflammation or infection seems likely to be the underlying process. It is mainly using glucocorticoid with immunosuppressant therapy at present. Timely and effectively control inflammation can effectively prevent vision loss, choroidal neovascularization and choroidal scar in SC patients.
Objective To observe multimodality imaging features of different properties in multifocal choroiditis (MFC). Methods Twenty-eight patients (51 eyes) with MFC were enrolled in this study. There were 10 males and 18 females. The patients aged from 31 to 49 years, with the mean age of (41.5±0.8) years. There were 23 bilateral patients and 5 unilateral patients. All patients underwent best corrected visual acuity (BCVA), slit-lamp biomicroscopy, indirect ophthalmoscopy, fundus colorized photography, infrared fundus photography, fundus autofluorescence (FAF), fundus fluorescein angiography (FFA) and optical coherence tomography (OCT) examinations. The lesions were classified as active inflammatory lesion, inactive inflammatory lesion, active choroidal neovascularization (CNV) and inactive CNV. The multimodality imaging features of different properties in MFC was observed. Results In fundus colour photography, the boundaries of active inflammatory lesions were blurry, while inactive inflammatory lesions had relatively clear boundaries. Secondary active CNV showed mild uplift and surrounding retinal edema; Secondary active CNV lesions showed mild uplift, retinal edema around the lesion; Secondary non-active CNV had no retinal exudate edema lesions, but had lesions fibrosis and varying degrees of pigmentation. Infrared fundus examination revealed that both active and inactive inflammatory lesions showed a uniform punctate or sheet-like fluorescence. The fluorescence of CNV lesions was not uniform; there was a bright ring around the strong fluorescence. FAF found that active inflammatory lesions showed weak autofluorescence (AF), surrounded by a strong fluorescence ring; inactive inflammatory lesions showed AF loss. Secondary active CNV lesions showed strong AF with a bright ring along the edge, and obscured fluorescence for co-occurred hemorrhagic edema; secondary non-active CNV lesions were strong AF, surrounded by a weak AF ring. FFA revealed that active inflammatory lesions showed weak fluorescence in the early stage, and fluorescence gradually increased in the late stage with slight leakage. Inactive inflammatory lesions showed typical transmitted fluorescence. Fluorescein leakage secondary to active CNV was significant; lesions secondary to inactive CNV showed scar staining. In OCT, the active inflammatory lesions showed moderately weak reflex signals in the protruding lesions under the retinal pigment epithelium (RPE). The inactive inflammatory lesions showed penetrable RPE defects or choroidal scar, it also showed clear RPE uplift lesions with a strong reflection signal. Secondary active CNV showed subretinal fluid retention; secondary non-active CNV showed RPE defects and choroidal scarring. Conclusions Active inflammatory lesions in MFC have blurred boundary, retinal edema and fluorescein leakage in FFA; inactive inflammatory lesions have clear boundary and typical transmitted fluorescence in FFA, and no retinal edema. Secondary active CNV showed subretinal fluid in OCT; and secondary non-active CNV showed RPE defects and choroidal scarring.
