Objective To observe ophthalmoscopic image characteristics of central serous chorioretinopathy (CSC). Methods Twenty-one eyes of the 18 patients diagnosed with CSC were enrolled in this study．The patients included 12 males (14 eyes) and six females (seven eyes)．The patients ages ranged from 26 to 47 years，with a mean age of (39.1plusmn;5.4) years. There were nine patients (11 eyes) with acute CSC, seven patients (seven eyes) with chronic CSC, and two patients (three eyes) with recurrent CSC. All the patients were examined using color fundus photography including infrared (IR), auto-fluorescence (AF), near infrared ray-auto-fluorescence (NIR-AF), fluorescein angiography (FA) and indocyanine green angiography (ICGA) photography. The ophthalmoscopic image characteristics of CSC were comparared. Results The circular serous retinal detachments of 21 eyes were depicted in color images of the ocular fundus, which in the IR showed the hypo-fluorescence. Ten eyes displayed mottled hyper-fluorescent spots associated with serous retinal detachments corresponding to the leakage points. The serous retinal detachments of 15 eyes in the AF images showed hypo-fluorescence, six eyes showed hyper-fluorescence. Fourteen eyes presented with hypo-or hyper-fluorescent spots corresponding to the leakage points, seven eyes presented without abnormal fluorescence corresponding to the leakage points. In addition, three eyes with acute CSC showed many scattered hyper-fluorescent spots, which showed hypo-fluorescence in the ICGA. The serous retinal detachment of 15 eyes exhibited hypo-fluorescence in the NIR-AF images, six eyes showed hyper-fluorescence. Fourteen eyes presented with hypo- or hyper-fluorescent spots corresponding to the leakage points, seven eyes presented without abnormal fluorescence corresponding to the leakage points. Twenty-one eyes in FA identified the leakage. Eight eyes showed regional choroidal delayed filling, 13 eyes exhibited regional choriocapillary dilatation during 1-5 minutes after injection of ICGA. During 1-5 minutes after injection of ICGA, six eyes showed more lesions than FA, three eyes showed obvious patchy hypo-fluorescence whereas the FA were normal. Conclusions CSC has its own characteristic fundus images in the IR, FA and NIR-A. FA is still the photographic method of choice, but ICGA can reveal lesions of the choroid in CSC. IR, FA and NIR-AF are not as good as FA and ICGA for detecting of leakage points.
Objective To observe the clinical features of combined central retinal artery and vein occlusion. Methods The clinical data of eight patients of combined central retinal artery and vein occlusion diagnosed by fundus examination and fundus fluorescein angiography (FFA) was analyzed retrospectively, including the causes, fundus manifestations and FFA features. Results 4/8 patients had hypertension and dyslipidemia, 2/8 patients had traumatic retrobulbar hemorrhage, one patient had orbital cellulitis and one patient had systemic lupus erythematosus. All the patients had posterior pole retinal edema, hemorrhage, thin retinal artery, dilated vein, and papilledema. FFA showed delayed arterial filling, and there was no filling of retinal arterial branches until the late stage of FFA. Laminar flow delayed in large retinal veins, and there was no filling or only retrograde filling in retinal vein branches. Large areas with dot-like or patchy weak choroidal fluorescence can be observed in five patients. Conclusions Combined central retinal artery and vein occlusion is rare with complex etiology. The fundus manifestations and FFA features are atypical, but have features of central retinal artery occlusion and central retinal vein occlusion.
Objective To observe the characteristics of fundus fluorescein angiography (FFA) in different types of pathologic myopic maculopathy and evaluate the influence factor.Methods The clinical data of 251 patients (451 eyes) with pathologic myopic maculopathy were retrospectively analyzed. The patients were divided into 6 groups according to FFA characteristics: (1) lacquer cracks (LC); (2) choroidal neovascularization (CNV); (3) macular hemorrhage with LCs; (4) Fuchs spots; (5) macular atrophy; (6) macular hole. Their relationship with age, gender, refraction and (BCVA) were analyzed.Results Older age was significantly associated with CNV and macular atrophy (OR=1.034,CI=1.019-1.049,P＜0.001;OR=1.054,CI=1.031-1.076,P＜0.001; respectively);younger age was associated with hemorrhage with LC (OR=0.906,CI=0.876-0.937,P＜0.001). Higher myopic refractive error was associated with macular atrophy (OR=0.762,CI=0.705-0.824,P＜0.001), whereas lower myopic refractive error was associated with CNV and macular hole(OR=1.233,CI=1.136-1.338,P＜0.001;OR=1.554,CI=1.185-2.038,P＜0.001; respectively). A worse visual acuity was associated with CNV (OR=1.835,CI=1.180 -2.854,P=0.007), while better visual acuity was associated with LC (OR=0.506,CI=0.328 - 0.782,P=0.002). There was no gender difference in distribution of high myopic maculopathy types. Conclusions Pathologic myopic maculopathy can be divided into six types. With increasing age, the incidence rates of CNV and macular atrophy increases, hemorrhage with LC but decreases. With the rise of myopic refractive, the incidence rates of CNV and macular hole decreases, macular atrophy but increases.
Objective To observe the clinical features of polypoidal choroidal vasculopathy (PCV) with retinal pigment epithelium (RPE) tears. Methods Twelve patients of PCV with RPE tears (12 eyes) were enrolled in this study. The patients included eight males and four females, with a mean age of 58.6 years (from 39 to 71 years old). All the patients were affected unilaterally, including eight right eyes and four left eyes. There were one eye with serous RPE detachment and 11 eyes with hemorhagic RPE detachment. All the patients were examined for fundus photography, fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA), three patients were examined for optical coherence tomography (OCT). The location of RPE tear was classified as within vascular arcade, on vascular arcade, and outside vascular arcade. The shape of tear was classified as crescent, semilunar, or irregular. The features of fundus, FFA, ICGA and OCT were observed. Results Fundus examination presents a gray lesion in all eyes. The location of tear were within vascular arcade in four eyes (33.3%), on vascular arcade in five eyes (41.7%) and outside vascular arcade in three eyes (25.0%). The shape of tears were crescent (one eye, 8.3%), semilunar (ten eyes, 83.3%) or irregular (one eye, 8.3%). The RPE tear region present transimitted fluorescence of at the early stage of FFA and hyperfluorescence with a clear border at late stage. There was no leakage, and at the border of hyperfluorescence, blockage fluorescence of rolled and contracted RPE was present. In ICGA manifestation, transimitted fluorescence was found in RPE tear region at early stage, and a clear border was seen in nine eyes at late stage. There was also blockage fluorescence in ICGA of contracted RPE. In OCT manifestation, the RPE reflections were disappeared, and at the margin of tear, the contracted RPE present a dense rolled b reflection. Conclusions In PCV patients, RPE tears are semilunar and usually located within or around the vascular arcade. Fundus angiography shows transimitted fluorescence at the RPE tear region, and curl blockage fluorescence at the edges. OCT shows RPE reflection is disappeared in the tear region and a b reflection at the edges.
Objective To observe the clinical manifestation and ophthalmoscopic image characteristics of uveal metastatic carcinoma. Methods Thirty-six uveal metastatic carcinoma patients (43 eyes) were enrolled in this study. The patients included 21 males and 15 females. The patientsprime; ages ranged from 28 to 71 years, with a mean age of (47.3plusmn;10.2) years. Seven patients had bilateral carcinoma and 29 patients had unilateral carcinoma. There were 30 patients with lung cancer, three patients with breast cancer, one patient with gastric cancer and two patients without primary tumors. There were 20 patients with known primary cancer, 16 patients visited the Department of Ophthalmology first. All the patients were examined documenting visual acuity, intraocular pressure, slit-lamp microscopy and mydriatic fundus examination. Meanwhile, 22 patients (26 eyes) were examined using B-type ultrasound and/or color Doppler flow imaging (CDFI). Twelve patients (12 eyes) were examined using fundus fluorescein angiography (FFA) and/or indocyanine green angiography (ICGA). Seventeen patients (22 eyes) were examined using MRI and/or CT. The clinical manifestation and ophthalmoscopic image characteristics of uveal metastatic carcinoma patients were observed. Results Among 43 eyes, four lesions were in the iris, three lesions in the ciliary body and 32 lesions were in the choroid. Fundus examination showed an isolated mass in 26 eyes and more than two masses in nine eyes. Metastatic tumors of the iris and ciliary body often showed irregular cauliflower-like mass with gray-white or meat-red color and abundant vessels. The choroidal metastasis usually demonstrated flat rounded or irregular intraocular masses with gray-yellow or gray-white color in the posterior pole. B-type ultrasound showed ill-defined, flat, and irregular-shaped masses with uneven internal reflectivity. CDFI showed rich blood flow within the tumor. FFA and (or) ICGA showed pinpoint and mottled leaks against hyperfluorescence background. MRI revealed low or middle signal using T1WI and low signal intensity using T2WI. Conclusions The uveal metastatic carcinoma usually occurs in one eye with an isolated mass. Most of them show a flat gray-yellow mass in posterior choroids and have the primary cancer sites of the lung. FFA and/or ICGA show pinpoint and mottled leaks against hyperfluorescence background. B-type ultrasound and (or) CDFI show ill-defined, flat, and irregular-shaped mass with rich blood flow within the tumor. MRI reveals low signal intensity on T2WI.
Objective To evaluate the application value of iris fluorescein angiography (IFA) in the diagnosis of ischemic center retinal vein occlusion (CRVO). Methods Fifty-one patients (51 eyes) with CRVO which had been diagnosed by fundus fluorescein angiography （FFA）were studied. All patients underwent the examination of visual acuity, slit lamp biomicroscope，anterior segment color photography, intraocular pressure, FFA and IFA. The patients were classified as non-ischemic CRVO （20 eyes）and ischemic CRVO （31 eyes）. The 20 non-ischemic CRVO patients included 11 males and nine females, aged from 41 to 59 years. The 31 ischemic CRVO patients included 21 males and 10 females, aged from 28 to 62 years.FFA and IFA were performed for all the patients using Heidelberg retina angiograph, and the classic pictures were analyzed by the computer image processing system. The detection rate of iris neovascularization (NVI) by slit lamp biomicroscope and IFA was analyzed. All ischemic CRVO eyes underwent panretinal photocoagulation (PRP), and PRP was completed in 27 eyes and not completed in four eyes. Six months after PRP the regression of iris NVI was followed up. Results All non-ischemic CRVO eyes （100.0%） had no neovascularization on papillary margin and iris by slit lamp biomicroscopy, and had no fluorescence (pigment blocked fluorescence) on IFA. Thirteen eyes （41.9%） and 23 eyes （74.2%） of the 31 ischemic eyes had NVI by slit lamp biomicroscope and IFA, respectively. The NVI detection rate of those two methods was statistically different （Z=-3.425，P=0.001）. NVI showed b fluorescence and leakage with variable patterns (small blocks, thin lines and irregular cross-links) by IFA. There was no fluorescence staining and leakage on papillary margin and iris in 27 eyes who completed the PRP, but the neovascular glaucoma (NVG) occurred in one eyes who discontinued the PRP treatment after one to two months. Conclusions IFA has a high specificity in CRVO which hints the ischemic state of anterior segment. It is helpful to the early diagnosis of ischemic CRVO and the turnover of NVG.
Objective To investigate the characteristics and diagnostic value of fundus fluorescein angiography (FFA) for familial exudative vitreoretinopathy (FEVR). Methods 34 children (68 eyes) with FEVR and 64 parents (128 eyes) were included. All the clients were received examinations of slit-lamp biomicroscopy and indirect ophthalmoscopy. Meanwhile the children were examined by RetcamⅡ,the best corrected visual acuity of parents were recorded. The children and their parents were classified according to the ocular findings. Among 68 eyes of children, 3 eyes (4.41%) were normal, 4 eyes (5.88%) were in stage 1, 7 eyes (10.29%) were in stage 2, 2 eyes (2.94%) were in stage 3, 8 eyes (11.76%) were in stage 4 and 44 eyes (64.71%) were in stage 5. Among 128 eyes of parents, 74 eyes (57.81%) were normal, 51 eyes (39.84%) were in stage 1, 1 eyes (0.78%) were in stage 2 and 2 eyes (1.56%) were in stage 5. FFA was performed on the children with RetcamⅡunder anesthesia and on the parents with HR2 in order to observe the FFA characteristics in different stage. Results FFA characteristics in children included uncompleted vascularization of the periphery, peripheral avascular zone (stage 1); neovascularization and/or peripheral subretinal and intraretinal exudation (stage 2); subtotal retinal detachment with attached fovea (stage 3); subtotal retinal detachment with detached fovea (stage 4) and total retinal detachment (stage 5). FFA characteristics in parents included abrupt cessation of the peripheral retinal capillary network and a peripheral avascular zone (stage 1); abnormal peripheral arteriovenous shunts, neovascularization or exudation (stage 2) and atrophia bulbi (stage 5). Conclusions FEVR in different stage has different FFA characteristics. FFA plays an important role in early diagnosis of FEVR.
Objective To observe the clinical and fundus angiography characteristics of multiple evanescent white dot syndrome (MEWDS). Methods Forty eyes of 40 patients (12 males/28 females) with MEWDS, diagnosed by fundus fluorescein angiography (FFA) or indocyanine green angiography (ICGA) were enrolled. All cases were unilateral. The age was ranged from 16 to 64 years old, with a mean of 29.4 years. The initial average corrected vision was ranged from 0.1 to 1.0, with a mean of 0.82. The characteristics of clinical manifestations, the features of FFA and ICGA were analyzed.Results Multiple graywhite dots (100-500 mu;m) were found throughout the posterior pole and the mid-periphery areas. The lesions were at the depth of outer retina and retinal pigment epithelium layers. Some patients presented with mild vitreous opacity. FFA showed round or ring hyper-fluorescence spots at the early stage and tissue staining at the late stage, corresponding to the gray-white dots. Hyper-fluorescence spots and leakages at the retinal veins near optic disk were seen in 18 patients. The hyper-fluorescence spots near macular area were found in 7 patients. ICGA showed that numerous dark hypo-fluorescent dots in the mid-periphery and posterior pole at the early stage and no leakage at the late stage. ICGA detected more lesions than FFA. All of the patients were recovered without any visual complications within 6-8 weeks. Conclusions MEWDS patients have multiple fundus gray-white dots, and hyper-fluorescence and the abnormal retinal vessels by FFA, and multiple weak hypo-fluorescent spots throughout the posterior pole and the mid-periphery areas clearly on ICGA. The ICGA showed more lesions than the ophthalmoscope and FFA examination.
Objective To observe the autofluorescence (AF) manifestation in children with hereditary retinal diseases.Methods The clinical data of 22 children (aged from 5 to 14 years) with hereditary retinal diseases were retrospectively analyzed. There were 8 children (16 eyes) with Best vitelliform macular dystrophy, 3 children (6 eyes) with Stargardt macular dystrophy, 3 children (6 eyes) with macular cone dystrophy, 5 children (10 eyes) with primary retinitis pigmentosa, and 3 children (6 eyes) with Xlinked juvenile retinoschisis. The routine clinical examinations included present history, family history, visual acuity, silt-lamp microscopy, indirect ophthalmoscopy, color fundus photography and fundus autofluorescence angiography (FAF). Some patients received fundus fluorescein angiography (FFA), electroretinogram (ERG), electrooculogram (EOG), and ocular coherence tomography (OCT). The characteristics of AF in all the children were analyzed, and were compared with the images of color fundus and/or FFA. Results Symmetry round macular fluorescent weak or absent area was found in all Stargardt disease and cone dystrophy. Weak AF area with surrounded circular increased AF was found in 2 children (4 eyes) with cone dystrophy and 1 child (2 eyes) with Stargardt macular dystrophy. A central round area with regular or irregular intense AF was observed in Best vitelliform macular dystrophy. RP children showed increased AF out of the macular region. Cellular or granular b AF was found in the fovea of 3 children (5 eyes) with Xlinked juvenile retinoschisis. Conclusion The children with hereditary retinal diseases had special AF changes.
Objective To analyze the characteristics of images of fundus fluorescein angiography (FFA) in patients with central serous chorioretinopathy (CSC).Methods We observed the positions of leakage spots of retinal pigment epithelium (RPE) and analyzed their characteristics in 598 CSC patients. The ages, visual acuty, detachment areas of sensory retina, and leakage patterns of RPE were recorded and the correlation of them were analyzed. Results The leakage concentrated in the posterior pole, which occurred more frequently in the superior quadrant, nosal quadrant, and near fovea regions than in the inferior quadrant,temporal quadrant, and far regions from fovea, respectively (chi;2=67.13,20.93, 212.715; Plt;0.01).We found that there were relations between the ages of patients and the patterns of the leakage. A total of 35 patients (54.7% out of 64) at the age of ge;50 had small leakage; 82 patients (53.2% out of 154) at the age of 35-39 had diffusing leakage. Smaller retinal detachment in patients with multiple serous leakage and bigger retinal detachment area in patients with single serous leakage were found; no statistical significance was found (F=1.925,Pgt;0.05). There was negative correlation between the visual acuity and the detachment area in CSC patients (t=-0.335,Plt;0.01), and there was no correlation between the visual acuity and the distances from the leakage spots to the fovea (t=-0.029, -0.145;Pgt;0.05).Conclusion The leakages occurs in various regions whose difference is significant; the patterns of leakage are related to the ages; there is no relation between the serous retinal detachment area and the number of the leakage.
