ObjectiveTo investigate the clinical features and prognosis of patients with choroidal tuberculoma. MethodsA retrospective and observational study. From 2011 to 2022, 15 patients (16 eyes) with choroidal tuberculoma diagnosed and treated in Department of Ophthalmology, Shanghai Eye & ENT Hospital of Fudan University were included. The patients underwent examinations including best corrected visual acuity (BCVA), fundus color photography, optical coherence tomography (OCT), fluorescein fundus angiography (FFA), and indocyanine green angiography (ICGA). Chest CT examination, purified protein derivative test and interferon-γ release test were also performed. BCVA was performed using the Snellen visual acuity chart, which was converted to Logarithm of the minimum angle of resolution (logMAR) visual acuity when recorded. All the patients received antitubercular therapy and the duration was 12-15 months. Thirteen patients were combined with oral corticosteroids. The average follow-up time was 36 months. Rank sum test was used to compare logMAR BCVA before and after treatment. ResultsAmong the 15 patients, 5 were male and 10 were female; 1 case was bilateral involvement; 7 patients had a strong positive tuberculin skin test; 8 patients had a positive interferon-γ release assay. Six patients had pulmonary tuberculosis. One patient had peritoneal tuberculosis. Lesions were located in the posterior pole in 12 eyes, 1 eye with papillary tuberculoma. Peripheral lesions were found in 4 eyes. There were 9 eyes each with anterior segment inflammation or vitreous inflammation; 7 eyes were with exudative retinal detachment. OCT examination revealed a hyporeflective thickening of the choroidal stroma, the corresponding elevation of the retina, and often accompanied by subretinal fluid. FFA revealed hyperfluorescence of the mass and fluorescence accumulation with subretinal fluid at the late stage. ICGA revealed hypofuorescence of the lesion. The lesions subsided after treatment, and there was no recurrence during follow-up period. Cataract surgery was performed in 4 eyes due to complicated cataract. One eye undergone vitrectomy due to secondary rhegmatogenous retinal detachment. Anti-vascular endothelial growth factor therapy was performed in 1 eye due to secondary choroidal neovascularization. Ocular wall perforation occurred in 1 eye, and the condition was stable after treatment. Before treatment, the average logMAR BCVA was 1.02±0.57, which improved to 0.31±0.35 after treatment. The difference between the mean logMAR BCVA before and after treatment was statistically significant (P＜0.05). ConclusionsCombination of medical history, clinical manifestations, laboratory tests, and imaging can assist in the diagnosis of choroidal tuberculoma. The main manifestations are subretinal yellowish-white lesions in posterior pole. Standardized anti-tuberculosis therapy can effectively improve the prognosis of vision.
Objective To observe the clinical features of acute zonal occult outer retinopathy (AZOOR).Methods Eighteen patients (18 eyes) with AZOOR were enrolled in this study. All the patients were examined for corrected visual acuity, fundus examination, visual field and electroretinography (ERG). For part of these patients, fluorescein angiography (FFA), optic coherence tomography (OCT), visual evoked potential (VEP) and multifocal ERG (mf-ERG) were performed. Clinical features were observed. Comparative analysis was performed on the electrophysiological results between affected eyes and fellow eyes. The consistency of OCT, visual field and mf-ERG results was investigated.Results The patients included three males and 15 females. All patients were unilateral involved. 16 eyes (88.9%) were myopia, two eyes (11.1%) were emmetropia. 11 eyes (61.1%) have normal fundus; single yellow-white punctuate lesion or old RPE lesion near macular were found in three eyes (16.7%); depigmented zones in temporal retina were found in four eyes (22.2%). All central visual field results were abnormal, but peripheral visual field results were normal. OCT findings included irregularity, absence or breaks of the photoreceptor inner segment/outer segment (IS/OS) junction. Amplitudes of full-field ERG were reduced in the affected eyes (t=3.516，2.689，3.103，3.517，2.999，3.309；P＜0.05), and implicit times were delayed in most responses except for rod response (t=1.023,P=0.306). Amplitudes of P100 wave of visual evoked potential were reduced statistically (t=2.04,P=0.041), but the differences of implicit times between the affected eyes and the fellow eyes were not statistically significant (t=1.687,P=0.092). Amplitude reduction of multifocal ERG existed in all affected eyes. Coincidence was found between results of OCT and mf-ERG. But abnormal zones found by central visual field did not always coincide with those by mf-ERG. Conclusions The majority of patients who develop AZOOR are young women with myopia. Most patients have normal fundus. Central visual field and electrophysiological examinations are always abnormal. Irregularity, absence or breaks of the photoreceptor IS/OS junction can be proved by OCT.
ObjectiveTo investigate the clinical characteristics of 40 patients with ocular toxocariasis (OT) on the first attendance. MethodsA total of 40 consecutive patients who were clinically and serologically diagnosed with OT were retrospectively reviewed. ResultsThe mean age of patients was (12.12±10.42) years. There were 29 males and 11 females. 29 cases presented with decreased vision, 4 children with leukocoria, 2 cases with strabismus and 5 cases was found abnormal during regular eye examination. Initially 8 eyes (20%) were misdiagnosed as retinoblastoma (1 eye), Coat's disease(1 eye), cataract (2 eyes), iridocyclitis (2 eyes) and retinal detachment (2 eyes). 23 eyes had retinal detachment, 19 eyes had cataract. OT was the initial diagnosis for 15 patients (37.5%). The best corrected visual acuity (BCVA) were NLP to 0.7. Ultrasound biomicroscopy (UBM) were performed in 29 eyes, and identified peripheral granulomas in 23 eyes and adjacent tractional retinal detachment in 12 eyes. We also identified 17 cases (68.0%) with elevated IgE level among 25 patients with positive serological antibody test. ConclusionsTractional retinal detachment, vitreous opacities and cataract are the common clinical findings at the first attendance of OT patients. The adjunctive test of serum total IgE level may be helpful for the diagnosis. The application of UBM and specific IgG detection in serum and intraocular fluid, can also improve the diagnosis.
Mucosa-associated lymphoid tissue (MALT) lymphoma is an indolent B cell derived non-Hodgkin's lymphoma. It is the main type of uveal lymphoma and is extremely rare. The pathogenesis of ocular MALT lymphoma remains unclear. It is now considered to be associated with many causes. The manifestations of primary uveal MALT lymphoma differ. So sometimes it is necessary to diagnose depending on diversity of auxiliary tests. Ultrasound examination shows typical low and homogeneous internal reflectivity, with blood flow signal. Optical coherence tomography, fundus imaging, fundus angiography, magnetic resonance imaging and positron emission tomography computerized tomography can assist diagnosing. Primary uveal MALT lymphoma is sensitive to radiation therapy, chemotherapy and biotherapy have positive influence too. The prognosis of uveal MALT lymphoma is good, but its early diagnosis is rather challenging. The nonspecific clinical manifestations and the rarity of the disease can confound the initial diagnosis, resulting in delayed treatments which may cause irreversible vision loss.
Objective To observe the optical coherence tomography (OCT) features of Best vitelliform macular dystrophy (BVMD) at different stages.Methods Twenty-eight BVMD patients (56 eyes) were enrolled in this study. All the patients were examined for visual acuity, slit-lamp microscopy, direct ophthalmoscope, fundus photography, electrooculogram, fundus fluorescein angiography (FFA) and OCT. Fifty-six eyes were classified into stage 0 (eight eyes)、Ⅰ (two eyes)、Ⅱ(10 eyes)、Ⅱa （12 eyes）、Ⅲ (six eyes) 、Ⅳa (six eyes)、Ⅳb (five eyes) and Ⅳc (seven eyes) accordingly. The OCT features of BVMD at different stages were observed.Results The OCT results showed that the macular area was normal in eyes of stage 0; disturbance of retinal pigment epithelium (RPE) and subretinal hyporeflective area were found in eyes of stage I; the location of the yellowish material between RPE and the inner segment and outer segment (IS/OS) with normal appearance in RPE and IS/OS interface were found in eyes of stage Ⅱ. In all the other progressing stages from Ⅱa、Ⅲ and Ⅳ, the vitelliform material appeared as a thicker highly reflective lesion located between the outer nuclear layer and RPE layer, usually accompanied by optical hyporeflective lesion. Images of stage Ⅳc were in similar appearance besides edema of retina. OCT images of Ⅳb stage were demonstrated atrophy of retinal layer and IS/OS loss with fibrosis. Conclusions OCT demonstrated the location of the yellowish material between RPE and IS/OS. Optical hyporeflective lesion between the outer nuclear layer and RPE layer accompanied thicker highly reflected lesion might be the characteristic image in stages II a to IV of BVMD.
Objective To provide reference for hospital emergency preparedness for disasters in China by summarizing the main results from articles involving hospital emergency readiness. Method We systematically searched MEDLINE (1950 to June 2008), CNKI (1980 to June 2008) and some websites. The main results of the eligible articles are described. Results A total of 85 articles were included, of which expert articles and surveys accounted for 44% and 29%, respectively. An emergency hospital plan should address the following 4 phases of disaster management: mitigation, preparation, response, and recovery. The following factors should be considered when developing hospital emergency plans: surge capacity, disaster planning, collaboration, training, drill, personnel, equipment, triage, diagnosis, treatment, decontamination, funding, individual security, logistic, psychological support, etc. Questionnaires, checklists or specific tools could be applied to evaluate such emergency plans. Conclusion Hospital emergency preparedness is essential for effective disaster relief. Hospitals should develop emergency plans for a variety of disasters, based on their local situations.
ObjectivesTo evaluate the methodological quality of guidelines for pharmacological intervention of migraine in adults, to compare and analyze the differences in first-line drug recommendations in different regions and quality levels, so as to explore the evidence of drug recommendations, and provide a basis for clinical decision-making.MethodsPubMed, The Cochrane Library, EMbase, SinoMed, CNKI, VIP, and WanFang Data databases, Up To Date, as well as the related books, Yimaitong, Guideline Central, Guidelines International Network (GIN) and National Institute for Health and Clinical Excellence (NICE) were systematically searched to collect pharmacological intervention guidelines of migraine in adults from inception to January 12th, 2020. The methodological quality of the guidelines was evaluated by Appraisal of Guidelines for Research and Evaluation Ⅱ (AGREE Ⅱ).ResultsA total of 25 guidelines were included (including 22 evidence-based guidelines), covering 10 countries on 4 continents and World Health Organization (WHO) with a time span of 1997 to 2019. According to AGREE Ⅱ, 5 were A-level guidelines, 18 were B-level guidelines, and 2 were C-level guidelines. Scope and purpose, rigour of development, clarity of presentations and editorial independence obtained high average scores (more than 60%) among all 25 guidelines. The average scores of guidelines in different domains of AGREE Ⅱ varied with regions and countries. Triptans and NSAIDs were the most frequently recommended as first-line drugs for the acute management; beta-blockers and antiepileptic drugs were recommended for the first-line prevention drugs of migraine in adults. There were 2 guidelines that recommended complementary treatments, one recommended traditional Chinese medicine and another recommended herbal butterbur.ConclusionsThe methodological quality of the pharmacological intervention guidelines of migraine in adults is suboptimal among different regions or countries. The quality of evidence-based guidelines is superior to that established by consensus. The consistency of first-line drug recommendations is strong, but there are still regional differences. The therapeutic effect of traditional Chinese medicine requires further verification.
