Polypoidal choroidal vasculopathy in Caucasians

Purpose: To study the prevalence of polypoidal choroidal vasculopathy (PCV) in Caucasian patients with occult choroidal neovascularization (CNV); to study the clinical spectrum of PCV in Caucasians and the outcome after laser photocoagulation of such lesions. Methods: (1) A consecutive series of 374 eyes of Caucasian patients at least 58 years old, presenting occult CNV, presumed to have age-related macular degeneration (AMD) on fluorescein angiography (FA) were further characterized by indocyanine green angiography (ICGA) to determine the frequency of PCV. (2) The funduscopic, FA and ICGA findings in a cohort of 36 Caucasian patients with PCV were analyzed. (3) The outcome after laser photocoagulation was studied in 14 PCV eyes with a minimum follow-up of 6 months. Results: (1) Fourteen of 374 eyes (4%) presenting occult CNV in patients at least 58 years old were diagnosed as PCV by means of ICG-A. (2) A polypoidal lesion was found in the macula in 22 of 45 PCV eyes, in the peripapillary area in 16 of 45, under the temporal vascular arcade in 6 of 45 and in the midperiphery in 6 of 45. Large or soft drusen were observed in 15 of 45 eyes with PCV. (3) Regression of fundus signs without persisting polyps 6 months after laser photocoagulation was obtained in 5 of 5 treated peripapillary lesions but in only 5 of 9 treated macular or arcade lesions. Conclusion: Polypoidal choroidal vasculopathy is not rare in Caucasian patients presenting with occult choroidal neovascularization. The fundus abnormalities seen in such eyes overlap with the typical manifestations of AMD. Whereas the prognosis after photocoagulation of peripapillary polypoidal lesions appears to be relatively good, it is more guarded for macular or arcade lesions.

Characteristics of Indocyanine Green Angiography in Exudative Age—related Macular Degeneration

Objective: To observe the characteristics of indocyanine green angiography (ICGA) in exudative age-related macular degeneration (AMD).Methods: Thirty-one cases (39 eyes) were diagnosed as exudative AMD by ocular examination, fundus color photography, fundus fluorescein angiography (FFA) and ICGA. Their ages ranged from 50 to 82 years and visual acuities from FC/30cm to 0. 7. We analyzed and compared the characteristics of ICGA and FFA in these patients. Results: Of 26 eyes with occult choroidal neovascularization (CNV) by FFA, 15 (57. 7% ) had classic CNV by ICGA. Of 4 eyes with serous retinal pigment epithelial detachment (FED) without CNV by FFA, 1 had serous FED with classic CNV by ICGA. The hyperfluorescence of the scar staining was detecfed by ICGA. Conclusion ? ICGA adds clinically useful information and is an important adjunct in the evaluation, classification, and laser treatment of patients with occult CNV in AMD.

Fundus autofluorescence in multifocal choroiditis and panuveitis

PURPOSE: To investigate the autofluorescence findings associated with multifocal choroiditis and panuveits (MCP), a condition that has marked potential to affect the retinal pigment epithelium (RPE). DESIGN: Observational case series. METHODS: This is a retrospective review of consecutive patients with MCP examined in a retinal referral practice. Each patient was given a comprehensive examination including fundus photographs, angiographic studies, and autofluorescence photography with an excitation filter with the bandpass wavelengths of 535 to 585 nm and a barrier filter with a bandpass of 615 to 715 nm. Integrative analysis was performed of the ocular imaging to ascertain abnormalities caused by the disease. RESULTS: Thirty-six eyes of 18 consecutive patients were evaluated. The mean duration of symptoms was 86.2 months and the mean visual acuity was 20/50. Of the 36 eyes, 23 had choroidal neovascularization (CNV). Chorioretinal hypoautofluorescent spots >or= 125 microns usually, but not always, had the clinically evident correlate of a punched-out scar visible by color fundus photography. Chorioretinal hypoautofluorescent spots less than 125 microns, which could number in the hundreds, typically were not visible by color fundus photography. All chorioretinal scars visible by color fundus photography were visible by autofluorescence photography. During follow-up many patients developed new clinically evident chorioretinal scars, which were presaged in earlier autofluorescence photographs. CNV had a hyperautofluorescent boundary, making it readily visible. CONCLUSIONS: Patients with MCP have much more widespread involvement of the RPE than would be suspected by other means of imaging. Autofluorescence photography supplies information about inflammatory damage and secondary CNV in a noninvasive manner.     

Polypoidal choroidal vasculopathy coexisting with exudative age-related macular degeneration

Purpose To report two cases that had polypoidal choroidal vasculopathy (PCV) coexisting with choroidal neovascularization (CNV) of exudative age-related macular degeneration (AMD). Methods Both of the patients underwent color photographs, fluorescein and indocyanine green (ICG) angiography. Results On fundus examination, a grayish lesion in the foveal area, reddish-orange lesions and hemorrhagic retinal pigment epithelial detachments (PED) in the inferotemporal vascular arch were disclosed in the left eye of a patient, and macular scarring was observed in the fellow eye. ICG angiography revealed a typical branching vascular network and polyp-like aneurysmal dilations at terminals of branches in the inferotemporal vascular arcade and a well-demarcated hyperfluorescent area of CNV in the fovea in the left eye, and staining of macular scarring was present in the fellow eye. On fundus examination of the right eye of the other patient a gray–yellow lesion at the fovea, reddish-orange lesions in the extramacula were noted, and diffuse drusens were present in the fellow eye. ICG angiography revealed scattered polyp-like aneurysmal dilations without identifiable continuous branching vascular network in the extramacula, and a well-demarcated hyperfluorescence area of CNV in the fovea. Conclusions PCV can coexist with exudative AMD in some patients and the polypoidal lesions may less involve in the fovea than CNV. Evidence of AMD are present meanwhile in the fellow eyes these patients.

目的 探讨息肉状脉络膜血管病变(PCV)眼底荧光素血管造影(FFA)和吲哚青绿血管造影(ICGA)同步检查的影像学特征及其临床意义.方法 选取62例患者(75只眼)进行眼底彩色照相、FFA 和ICGA同步检查,对黄斑部视网膜下出血病灶其形态及特征做以对比分析.结果 FFA图像显示:PCV75只眼中斑块样视网膜下出血48只眼,占64.0%;伴浆液性视网膜色素上皮(RPED)脱离12只眼,占16.0%;出血性RPED8只眼,占10.7%;脉络膜血管网及息肉样结节7只眼,占9.4%,早期即出现荧光素渗漏并逐渐增强,CNV末端膨大处出现点状高荧光.ICGA图像显示:75只患眼中72只眼呈"蘑菇"状或"树枝"状异常扩张,其血管网末端多个息肉样膨大与彩色照相所见的结节样病变部位吻合.结论 FFA和ICGA同步检查,不但对PCV患者病灶其形态及特征作出对比分析,ICGA检查还能提高PCV视网膜下脉络膜新生血管膜(CNV)的检出率,同时提高PCV患者激光光凝的可能性,而FFA对评估PCV 视网膜下出血及出血性或浆液性视网膜色素上皮脱离、脉络膜血管网及息肉状结节则均有较好的效果.

Abstract：

Objective To observe on fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA) in polypoidal choroidal vasculopathy (PCV), and sync examine of its image features and clinical meaning. Methods Sixty-two patients (75 eyes) applied fundus camera, FFA and ICGA synchronous examination, do comparison analysis in macular sub-retinal hemorrhage shape and area. Results FFA image in 75 PCV patients showed 48 eyes (64.0%) with plaque sub-retinal hemorrhage, 12 eyes (16.0%) accompanied with retinal pigment epithelial detachments (RPED), 8 eyes (10.7%) with bleeding RPED, 7 eyes (9.4%) with choroid blood vessel net and polypoidal node of early stage flouresence leakage. ICGA showed that 75 eyes had abnormal choroid blood vessel net extension, 72 with "mushroom" shape or "tree-branch" shape with more polypoidal enlarge in the end which was the same as seen under ophthalmoscope. Conclusions It proves that FFA and ICGA synchronous examination, not only can be used for PCV patients' tissue shape and area comparison analysis, but also improves the finding rate of the choroidal neovascularization (CNV) in PCV, increases the feasibility of photocoagulation to PCV. FFA gives good result to evaluate PCV sub-retinal hemorrhage.

The diagnostic contribution of indocyanine green to fluorescein angiography in fellow drusen eyes of patients with wet age-related macular degeneration

PURPOSE: To assess the contribution of indocyanine green angiography (ICGA) to fluorescein angiography (FA) in evaluating fellow drusen eyes of patients with wet age-related macular degeneration (AMD) in the other eye. METHODS: The records of paired FA and ICGA of patients with dry AMD in one eye and wet AMD in the other eye were retrospectively reviewed. Based on color fundus photographs, drusen were graded to low, moderate, or high grade of severity on FA. The FA and ICGA findings were compared. RESULTS: Fifty-two pairs of eyes were included. Fluorescein angiography showed drusen of low severity in 11 (21.2%) eyes, of moderate severity in 31 (59.6%), and of high severity in 10 (19.2%). Leakage on both FA and ICGA was not demonstrated in any case of drusen of low or moderate severity. Only in 2 out of 10 eyes from the high severity group, 3.8% of the eyes of the whole study population, did ICGA reveal occult choroidal neovascularization (CNV) that was not observed on FA. CONCLUSIONS: In selected eyes with drusen of high grade severity, ICGA may detect occult CNV, unrecognized clinically or by FA. ICGA had a small contribution to the diagnosis of occult CNV in fellow drusen eyes with any degree of severity.
