ObjectiveTo analyze the clinical character of uveitis in second hospital of Jilin university. MethodsRetrospectively analyze the clinical data of uveitis patients referred to from Second Hospital of Jilin University from September 2009 to September 2014. According to anatomical location, the manifestation of these uveitis patients were divided into anterior uveitis, panuveitis, intermediate uveitis and posterior uveitis. To discuss the possible causes of these patients according to the general information and relevant clinical laboratory examinations results. ResultsThere were 1215 cases in this study, which included 587 male, accounting for 48.31%; and 628 female, accounting for 51.69%. The ratio of male-to-female was 0.93:1. The range of the age of these patients was from 4 to 91 years old. The mean age of these patients at the onset of these disease was (41.43±14.20) years. Of the 1215 cases, 40 male and 43 female were younger than 20 years. The ratio of male-to-female was 0.93:1; 412 male and 396 female were between 21 and 50 years old. The ratio of male-to-female was 1.04:1; 135 male 189 female were older than 50 years. The ratio of male-to-female was 0.71:1. There were 572 cases of anterior uveitis, accounting for 47.08%; 527 cases of panuveitis, accounting for 43.37%; 52 cases of intermediate uveitis, accounting for 4.28%; 64 cases of posterior uveitis, accounting for 5.27%. 703 cases had etiological diagnosis according to the clinical character and the auxiliary results, accounting for 57.68%. Vogt-koyanagi Haradal (VKH) syndrome, ankylosing spondylitis associated with uveitis and Behçet's disease were the common entity, accounting for 30.44%, 19.77% and 14.22% respectively. ConclusionsThe mean age of these patients in this study was older, compared to other reports. Female patients were more than male, especially in these patients older than 50 years. VKH syndrome, ankylosing spondylitis associated with uveitis and Behçet's disease were the common entities.
ObjectiveTo observe the clinical characteristics of adult patients with ocular toxoplasmosis (OT).MethodsThis study was a retrospective clinical trial. Among the 83 consecutive OT patients diagnosed in the Zhongshan Eye Center of Sun Yat-Sen University, 14 patients (16.9%, adult group) aged ≥18 years were included in the study from January 2017 to December 2019. A total of 14 OT patients (children group) aged less than 18 years who had consecutive visits from July to December 2019 were selected as controls. All patients underwent BCVA, slit lamp microscope, fundus color photography, and B-mode ultrasound examination. Eighteen cases underwent UBM examination, including 6 and 12 cases in the adult group and child group respectively; 23 cases underwent FFA examination, including 12 and 11 cases in the adult group and child group respectively. Snellen visual acuity chart was used for BCVA examination, which was converted into logMAR visual acuity in statistics. We compared the two groups of patients' residence (urban or rural), history of contact with dogs and cats, main symptoms, reasons for treatment, course of disease, and clinical and imaging characteristics and so on. For measurement data conforming to normal distribution, t-test was performed for comparison between groups; for Skewness distribution measurement data, rank sum test was performed for comparison between groups.ResultsCompared with the adult group and the child group, there was no significant difference in the canine-cat contact history (Z=2.661, P=0.257) and the time from first diagnosis to diagnosis (t=−0.186, P=0.351); compared with the children group and the adult group, the patient's living environment was mainly urban, and the course of disease was significantly shorter (Z=−2.005), and the difference was statistically significant (P=0.047). The logMAR BCVA of the adult group and the child group were 0.81±1.08 and 2.08±1.30, respectively, and the difference was statistically significant (Z=−2.811, P=0.004); compared with the child group, the adult group had lighter vitreous opacities, but the difference was statistical significance (Z=7.847, P=0.048). FFA examination revealed 20 cases of "fern-like" leakage of retinal capillaries. Among them, the adult group and child group were 10 (83.3%, 10/12) and 10 (90.9%, 10/11) cases respectively.ConclusionsAdult patients account for 16.9% of OT patients. Compared with children, adult patients mostly live in towns or cities, have a short course of disease, good vision at first diagnosis, and mild inflammation or hyperplasia of the vitreous cavity. FFA is helpful for the diagnosis of adult OT.
Objective To observe the clinical and multimodel image features in patients of acute macular neuroretinopathy (AMN) associated with COVID-19. MethodsClinical data and multimodal imaging results in 12 patients (24 eyes) of AMN associated with COVID-19 which were diagnosed in our Department of Ophthalmology, The Second Hospital of The Army Medical University ranging from December 2022 to January 2023 were included. All patients were examined by best-corrected visual acuity (BCVA), color fundus photography, optical coherence tomography (OCT), OCT angiography (OCTA), visual field tests, high-resolution computed tomography of the lungs and inflammation-related laboratory tests. After diagnosis, patients were reveived methylcobalamin and Ginaton therapy, 6 patients receiced intravenous dripping of dexamethasone. The follow-up time of this study was 4 weeks. ResultsThere were 1 male (2 eyes) and 11 females (22 eyes), with the mean age of (29.00±5.17) years. For all cases, decreased vision presented 1 to 2 days after patients being suffered from several flu-like symptoms of COVID-19. Ten eyes in 5 patients were at the acute phrase of AMN, which the vision decrease occurred 1-5 days after they were diagnosed with COVID-19; 14 eyes in 7 patients were at the progressive stage of AMN, which they were diagnosed with COVID-19 for more than 5 days. The BCVA of patients were 0.02-0.9, in company with one or more central/pericentral scotoma. Fundus ophthalmoscopy revealed reddish-brown lesion around macula, IR imaging demonstrated localized areas of hypo-shape lesions in the macula. For 16 eyes, their OCTA revealed a decreased density of blood flow in the deep layer of retinal capillary plexus, and OCT revealed that high reflex bands existed in the outer nuclear layer (ONL) and outer plexiform layer of the retina at the acute phrase of AMN, in accompany with hypo-reflection in ellipsoid zone (EZ) and interdigitation zone (IZ); for retina at the progressive stage of AMN, ONL became thinner in some cases and the continuation interruption occurred in EZ and IZ. For en-face OCT, high reflex bands with clear edges existed in the ONL and EZ layer of the retina at the acute phrase of AMN, but no high reflex bands existed in the ONL and EZ layers of the retina at the progressive stage of AMN. Instead, hypo-reflection with similar shape occurred in the EZ and IZ layers at the progressive stage of AMN. During treatment, 5 patients at the acute phrase reported a shrinking central scotomas and raised BCVA, otherwise the BCVA of 7 patients at the progressive stage changed slightly. For 10 eyes at the acute phrase of AMN, OCT revealed that the high reflex bands of ONL and OPL missed within 1 week. En-face OCT revealed the hyper-reflection in the ONL and EZ layers of retina in the acute phrase of AMN receded within 1 week, but hypo-reflection of ONL and EZ still presented. ConclusionsFor AMN associated with COVID-19, IR imaging demonstrated localized areas of hypo-shape lesions in the macula. OCT revealed high reflex bands in ONL and OPL of the retina at the acute phrase of AMN, but hypo-reflection of ONL and EZ still presented. The continuation interruption occurred in EZ and IZ at the progressive phrase. En-face OCT revealed hyper-reflection in ONL and EZ of the retina at the acute phrase which receded within 1 week, and hypo-reflection in EZ and IZ of the retina presented at all phrases during AMN progression.
ObjectiveTo assess the fundus characteristics and their associations with refractive error, best corrected visual acuity (BCVA) of highly myopic eyes in Chinese teenagers. MethodsThis is a cross-sectional and retrospective study. 544 teenagers (1050 eyes) with refraction more than -6.00 D were recruited from Tongren Eye Care Center. All participants underwent examinations including cycloplegic auto-refractometry and retinoscopy, BCVA, slit lamp and 45℃olor funds photography centered in macular. BCVA was recorded with logarithm of the minimum angle of resolution (logMAR) acuity. 988/1050 (94.1%) fundus photographs with clearly visible optic disc and fovea were selected for analysis. Degree of tessellation in optic disc and macular was defined by the exposure of choroidal vessel. Area of beta parapapillary atrophy (PPA), maximal and minimal diameter of optic disc, degree of fundus tessellation were measured by Image J software. Optic disc ovality was calculated by maximal diameter/minimal diameter. Associations between degree of tessellation, beta PPA area, optic disc ovality and refractive error, BCVA were analyzed. Presence of high myopic retinopathy, including chorioretinal atrophy, lacquer crack and Fuchs spot were also observed. ResultsMean spherical equivalent was (-10.66±2.63) D. Mean logMAR BCVA was 0.11±0.22. Tessellation was in 66.9% eyes. Mean degree in macular and peripapillary region was 0.83±0.96 and 1.04±1.00 (r=0.875, P=0.000). Beta PPA was in 97.3% eyes and mean area was (0.45±0.57) mm2. Mean ovality factor was 1.25±0.18 and Tilted optic disc was in 28.5% eyes. Refractive error, logMAR BCVA, beta PPA area, tilted optic disc and ovality factor were related with the degree of optic disc and macular tessellation (P < 0.05). Highly myopic retinopathy was found in 28 eyes, with older age, larger area of PPA, higher presence of tilted optic disc and degree of tessellation, worse BCVA. ConclusionsBeta PPA was the main fundus characteristics in teenagers. Visual acuity can be seriously impaired by highly myopic retinopathy, such as chorioretinal atrophy.
ObjectiveTo summarize and analyze the clinical characteristics of patients with acute diffuse lung changes and respiratory failure.MethodsThe clinical data of patients in the Department of Critical Care Medicine, Dazhou Central Hospital between January 2016 and December 2018 were retrospectively collected, whose main clinical manifestation was acute respiratory distress syndrome with acute onset (<3 weeks) and main imaging manifestation was diffuse changes in both lungs. The clinical characteristics of patients were summarized, and the causes of the disease were explored.ResultsA total of 65 patients with acute diffuse lung changes and respiratory failure were enrolled, including 42 males (64.6%) and 23 females (35.4%). The average age was (57.1±18.4) years, the average time from onset to treatment was (7.5±5.9) d, and the average length of stay in the intensive care unit was (8.9±4.1) d. A total of 23 cases died, with a case-fatality rate of 35.4%. Among the 65 patients, there were 50 case (76.9%) of infectious diseases, including 36 cases of bacterial infections (including 4 cases of tuberculosis), 8 cases of viral infections (all were H1N1 infections), and 6 cases of fungal infections (including 1 case of pneumocystis infection); and there were 15 cases (23.1%) of non-infectious diseases, including 4 cases of acute left heart failure, 2 cases of interstitial pneumonia, 2 cases of vasculitis, 1 case of myositis dermatomyositis, 1 case of aspiration pneumonia, 1 case of acute pulmonary embolism, 1 case of acute drug lung injury, 1 case of neurogenic pulmonary edema, 1 case of drowning, and 1 case of unknown origin.ConclusionsInfectious diseases are the main cause of acute diffuse lung changes and respiratory failure, while among non-infectious diseases, acute heart failure and immune system diseases are common causes.
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 analyze the onset, clinical manifestation, causation, complications of pediatric uveitis. Methods One hundred and two patients with uveitis under 16 year-old were retrospectively studied. They visited the clinic in Peking University First Hospital from November 1979 to December 2008. Their age ranged from 2.5 to 16 years old, with a mean of 11.9 years. Routine exam was carried out, including visual acuity, slit lamp, fundus, and laboratory workup. The diagnosis and classification were made by the anatomic location according to the standard of The International Uveitis Working Group. The data of disease history, age of onset, manifestation, recurrence, causation, systemic diseases, complications, and lab examination were analyzed.Results A total of 102 patients (170 eyes) with pediatric uveitis were included in this study, 68 patients (66.6%) were bilateral cases. Anterior uveitis represented in 38 patients (37.3%), intermediate uveitis in 19 (18.6%), posterior uveitis in 10 (9.8%), and panuveitis in 35 (34.3%). The disease duration was from five days to 2.4 years, with a mean of 3.6 months. The follow-up time was two weeks to more than ten years. The first three causes of pediatric uveitis were juvenile idiopathic arthritis, Vogt-Koyanagi-Harada disease, and Behccedil;etprime;s disease. 36 patients were found with complications, and among them 19 had complicated cataract, seven had secondary glaucoma, five had corneal band dystrophy, 12 had iris synechia (both anterior and posterior), one had retinal detachment, two had eye atrophy, and one patient with juvenile idiopathic arthritis had bilateral femoral head necrosis because of the use of steroid and hip joint was replaced. There were ten children suffering more than two complications. Conclusions Pediatric uveitis is a possible blindness disease with variety of etiology and manifestations,and tends to cause complications. Early and special attention must be taken to avoid serious consequences.
