ObjectiveTo observe the clinical features of uveal effusion syndrome (UES) and the efficacy of sclerectomy in the treatment of UES.MethodsA retrospective case series. Twenty patients (36 eyes) of UES with sclerectomy were enrolled in this study from June 2012 to December 2016 in Beijing Tongren Hospital. Among them, there were 12 males (22 eyes) and 8 females (14 eyes), with an average age of 37.8 years. All patients suffered from bilateral diseases, including 4 patients in single eye group and 16 patients in double eye group. Visual acuity, intraocular pressure, indirect ophthalmoscope, UBM, FFA combined with ICGA, A/B ultrasonography, axial length (AL) and scleral thickness were measured. All patients underwent lamellar sclerectomy, and those with exudative retinal detachment underwent four quadrant lamellar sclerectomy, followed by four quadrant full-thickness sclerectomy with the size of 1 mm × 2 mm in the center of the scleral bed. The follow-up time after operation was more than 6 months.Visual acuity, intraocular pressure and fundus examination were performed 1, 3 and 6 months after operation with the same equipment and methods before operation.ResultsThere was no obvious inflammation in the anterior chamber of all eyes, and intraocular pressure was 24-28 mmHg (1 mmHg = 0.133 kPa) in 4 eyes (11.1%). Axial length of 8 eyes (22.2%) were 16-18 mm (true microphthalmia). 12 eyes (33.3%) had scleral thickness＞1.0-1.8 mm. Visual acuity ranged from hand movement to 0.05 in 20 eyes, 0.1 to 0.3 in 10 eyes and＞0.3 in 6 eyes. Fundus examination showed peripheral choroidal and ciliary detachment; UBM examination showed annular peripheral ciliary and choroidal detachment. 32 eyes (88.9%) were complicated with exudative retinal detachment. FFA examination showed that 14 eyes (38.9%) had leopard spot changes. Compared with preoperative vision, the visual acuity improved in 28 eyes (77.8%) and remained unchanged in 8 eyes (22.2%) after surgery. Thirty-two eyes with different degrees of retinal detachment were found before surgery. After surgery, ciliary body detachment, choroidal detachment and retinal detachment were restored. Six eyes (16.7%) recurred and underwent sclerectomy again.ConclusionsThe mild symptoms and recurrent attack are the characteristics of UES. Sclerectomy is an effective method to treat UES.
ObjectiveTo observe the application value with color Doppler flow imaging (CDFI) in the detection of macular diseases in senile cataract.MethodsA cross-sectional descriptive study. From December 1 to December 30, 2017, 720 senile cataract patients (1380 eyes) diagnosed in Beijing Tongren Eye Center were included in this study. There were 330 males (629 eyes) and 390 females (751 eyes), with the mean age of 70.35±19.05 years. There were 716 right eyes and 664 left eyes, with the visual acuity 0.05-0.8. The fundus of all the patients can be observed. All patients were examined by OCT using Cirrus HD-Model 5000 produced by German Carl Zeiss company and CDFI using MyLab90 color Doppler ultrasound system produced by ESAOTE S.P.A. Comparing the detection rate of macular lesions between the two methods by using χ2 test. Using statistical methods to evaluate diagnostic tests, a crosstabulation was made to compare the consistency of frequency-domain OCT and CDFI in the diagnosis of macular lesions. Logistic regression analysis of correlation between detection of CDFI macular lesions and central foveal thickness (CFT), average thickness (AT), with or without macular anterior membrane, retinal folds, retinal cystoid edema, hard exudation, macular hole or lamellar macular hole, superficial detachment of neuroepithelium, detachment of pigment epithelium, vitreous macular traction.ResultsTwo hundreds and thirty-nine eyes (17.3%) showed macular disease by OCT, and 161 eyes (11.7%) showed the abnormal echo in the macular region by CDFI. The detection rate of the macular disease between two methods were statistically significant (χ2=851.661, P＜0.001), however, the consistency was well (κ=0.766, P=0.000). Logistic analysis showed that the detection rate of macular lesions was related to retinal folds, cysts in retina and CFT (r=1.396, 1.041, 0.12; P＜0.01).ConclusionCDFI can effectively detect macular lesions that affect the visual prognosis of senile cataract patients.
Objective To summarize the characteristics of color doppler flow imaging (CDFI) of ocular toxocariasis (OT) in children. MethodsA retrospective clinical study. From July 2014 to June 2020, 61 OT patients with 61 eyes diagnosed through clinical and laboratory testing in the Department of Ophthalmology of Beijing Tongren Hospital of Capital Medical University were included in the study. There were 45 males with 45 eyes and 16 females with 16 eye (male: female=2.81:1). Age were (6.93±2.50) years. The right eye and left eye were 29 and 32 eyes, respectively. Both eyes of the patient underwent two-dimensional ultrasound and CDFI examination. Two dimensional ultrasound was used to estimate the axial length (AL) of the affected eyes and healthy eyes on the opposite side. Among them, 52 cases were measured for AL using optical biometry and/or A-mode ultrasound. Vitreoretinal surgery was performed within one week after ultrasound examination. Two-dimensional ultrasound was used to observe the morphology of vitreous opacity, its connection to the eyeball wall, and whether posterior vitreous detachment and retinal detachment have occurred. CDFI examination was used to observe the presence of blood flow signals on the pathological membrane. The detection rates of different forms of vitreous opacity and traction retinal detachment were calculated. The location of proliferative lesions in the eye was analyzed. Paired t-test was performed to compare the AL of the affected eye and the healthy eye on the opposite side. Perform Kappa consistency test on the location of proliferative lesions was used during CDFI examination and vitreoretinal surgery. ResultsAll affected eyes have varying degrees of vitreous opacity. Among them, 23 eyes (37.7%, 23/61) showed typical "Christmas tree" like turbidity; 27 eyes (44.3%, 27/61) had clustered and striped echoes; 9 eyes (14.8%, 9/61) had weak punctate and strip echoes. Two eyes (3.3%, 2/61) showed a large amount of dense punctate and strip-shaped echoes. There were 50 eyes (82.0%, 50/61) with traction retinal detachment, of which 46 eyes (92.0%, 46/50) had visible blood flow signals on the detached retina, and the remaining 4 eyes (8.0%, 4/50) had no blood flow signals. During CDFI and surgery, there were 5 (8.2%, 5/61) and 4 (6.6%, 4/61) eyes with visible proliferative lesions in the periphery, respectively; 18 (29.5%, 18/61) and 14 (23.0%, 14/61) eyes were distributed in the posterior pole, respectively; there were 38 (62.3%, 38/61) and 43 (70.5%, 43/61) eyes with both peripheral and posterior polar regions, respectively. The consistency between CDFI and surgery in detecting the location of proliferative lesions was good (κ=0.832, 95% confidence interval 0.691-0.973, P＜0.001). The two-dimensional ultrasound measurement results showed that the AL of the affected eye was shorter than that of the contralateral healthy eye in 46 cases (75.4%, 46/61). Among the 52 patients who underwent AL biometry, the AL of the affected eye was shorter than that of the contralateral healthy eye by (0.63±0.68) mm, and the difference was statistically significant (t=－6.738, P＜0.05). ConclusionsCDFI can clearly display various intraocular lesions (vitreous opacity and traction retinal detachment) and eyeball sizes in children with OT. Vitreous opacity is often manifested as "Christmas tree" like, clustered, strip-shaped.
ObjectiveTo analyze the ultrasonographic features of adenoma of the nonpigmented ciliary epithelium (ANPCE). MethodsA retrospective series of case studies. From January 2014 to October 2021, 31 patients (31 eyes) with ANPCE (ANPCE group) were diagnosed in the eye center of Beijing Tongren Eye Center of Beijing Tongren Hospital, Capital Medical University, and 17 patients (17 eyes) with ciliary body melanoma (control group) diagnosed at the same time were selected as the control group. There was no significant difference in age (t=－0.564) and sex composition ratio (χ2=0.182) between the two groups (P=0.576, 0.670). All patients underwent ultrasound biomicroscopy to obtain the measurement parameters: tumor height, maximum basal diameter, maximum diameter, ratio of maximum diameter to basal diameter and ratio of maximum diameter to height; tumor location, shape, internal echogenicity intensity, echogenicity uniformity, degree of sound attenuation, invasion of iris, anterior displacement of the iris, lens subluxation were observed. The measurement parameters and observation indexes of the two groups were compared by independent sample t-test and χ2 test. Receiver operating characteristic (ROC) curve was drawn, area under the ROC curve (AUC) was determined, and parameter indicators with differential diagnosis value were screened. ResultsThe maximum diameter, height, maximum basal diameter, ratio of the maximum diameter to the maximum basal diameter, and the ratio of the maximum diameter to the height of the tumors in the ANPCE group and the control group were 5.64±0.98 mm, 4.24±0.59 mm, 3.66±0.71 mm, 1.58±0.34, 1.34±0.19 and 7.82±2.03 mm, 4.47±2.44 mm, 7.02±1.96 mm, 1.13±0.16, 2.09±1.06. The maximum diameter, the maximum basal diameter, and the ratio of the maximum diameter to the height of the tumor in the ANPCE group were all smaller than those of the control group, and the ratio of the maximum diameter to the maximum basal diameter was greater than that of the control group, and the differences were statistically significant (t=－4.159, －6.808,－2.924, 6.257; P<0.05). The tumors in the ANPCE group were mainly spherical (87.1%, 27/31), with no significant acoustic attenuation (77.4%, 24/31), less invading the root iris (77.4%, 24/31), and the tumors were mostly located in the ciliary body coronal (74.2%, 23/31); tumors in the control group were mainly hemispherical (47.1%, 8/17) or spherical (47.1%, 8/17), with significant sound attenuation (76.5%, 13/17), most of the tumors invaded the iris (70.6%, 12/17), and the tumors were mostly located from the pars plana to the coronal (76.5%, 13/17). There were statistically significant differences in the position, shape, sound attenuation degree, and whether it invaded the iris between the two groups of eyes (χ2=15.132, 19.767, 13.118, 10.581; P<0.05). The results of ROC curve analysis showed that the ratio of the largest diameter to the largest base diameter, the degree of sound attenuation and the AUC of whether the iris was violated were higher, which were 0.881, 0.769, and 0.740, respectively. ConclusionsUltrasound biomicroscopy is helpful in the diagnosis and differential diagnosis of ANPCE and ciliary body melanoma. The ratio of maximum diameter to maximum basal diameter, the degree of sound attenuation and whether it invades the root iris are important parameters to distinguish the two tumors.
Objective To observe the ultrasonographic features of idiopathic uveal effusion syndrome (IUES). MethodsA retrospective controlled study. From January 2012 to December 2023, 13 patients with IUES (26 eyes) diagnosed by ophthalmology examination in Department of Ophthalmonogy of Beijing Tongren Hospital (IUES group) and 22 healthy people with 30 eyes (control group) were included in the study. Both eyes of all participants were examined by color Doppler ultrasound (CDU) and ultrasonic biomicroscopy (UBM). The thickness of the ocular wall at 300 μm on the temporal side of the optic disc was measured by CDU. UBM was used to measure the thickness of the nasal and temporal scleral processes. Corneal thickness (CT), anterior chamber depth (AD), lens thickness (LT) and axial length (AL) were measured by A-mode ultrasound. There were no significant differences in age (t=0.842), sex component ratio (χ2=0.540), eye difference (χ2=0.108) and AL (t=0.831) between IUES group and control group (P＞0.05). The CDU and UBM imaging features and biometrics of IUES affected eyes were observed. Independent sample t test was used for comparison between groups. ResultsCDU examination results showed that in 26 eyes of IUES group, choroidal detachment occurred in 20 eyes (76.9%, 20/26), which showed arc-shaped band echo connected with peripheral and equatorial eye wall echo, with uniform low echo area below, and blood flow signal could be seen on the band echo. The echo thickened and decreased in 4 eyes (15.3%, 4/26). Nine eyes (33.3%, 9/26) were accompanied by retinal detachment, which showed that the posterior pole vitreous echo was connected to the optic disc echo, and the blood flow signal was seen on the ribbon echo. UBM results showed ciliary detachment in 22 eyes (84.7%, 22/26), showing a spongy thickening of the ciliary body with interlamellar echo separation and an echoless area between the sclera. Ciliary body echo thickened and decreased in 2 eyes (7.7%, 2/26). Shallow space between ciliary body and sclera was observed in 2 eyes (7.7%, 2/26). Compared with the control group, CT (Z=2.054), LT (Z=1.867), scleral thickness (Z=2.536) and ocular wall thickness (Z=2.094) were thickened in IUES group, and AD (Z=1.888) were decreased, with statistical significance (P＜0.05). ConclusionsThe CDU of IUES is characterized by a thickened echo of the ocular wall and a uniform low echo area under the detached choroid. UBM is characterized by a spongy thickening of the ciliary body echo with interlaminar echo separation.
