目的：探讨上睑提肌缩短术和额肌肌瓣悬吊术后眼表改变和恢复的差异。方法：对2007 年1 月至2007 年4 月在中山眼科中心住院的42例(62只眼)先天性上睑下垂患者，按手术方式和术后是否加用局部用药进行随机分组，观测各组术后2 d、5 d、7 d和2周患者泪液的分泌、泪膜破裂时间、结膜充血、角膜荧光染色、睑板腺功能、瞬目次数、上睑睫毛角度和眼睑闭合情况，并分析其观察结果的差异是否有统计学意义。结果：3名患者(7.1 ％)因需要加用其它促角膜上皮生长的药物而退出本研究，其中1例(2.3 ％)因倒睫刺激角膜上皮水肿缺损需行手术调整，其余所有患者眼表检测项目的结果均显示不同程度地受到了手术影响，但是随着术后炎症的逐渐消退，这些受影响的眼表异常均会逐渐恢复正常。泪膜破裂时间、瞬目次数、眼睑闭合情况的影响在两种术式之间的差异有统计学意义，而在术后是否局部用药之间没有统计学差异；角膜荧光素染色在是否加用局部用药组之间有统计学差异，而不同术式之间没有统计学差异；泪液分泌量、结膜充血、睑板腺功能、睫毛角度则在所有组别之间均没有统计学差异。结论：两种上睑下垂的矫正术均会引起患者眼表的改变，额肌肌瓣悬吊术对泪膜破裂时间、瞬目次数、眼睑闭合情况影响的程度较大，而局部用药只能改善角膜荧光素染色异常、对其它眼表因素影响不大。上睑睫毛角度异常是引起角膜损害最危险的因素。
Objective : To investigate the difference of ocular surface change and restoration after ex-ternal levator advancement and frontalis suspension.Methods : Forty-two patients (62 eyes) with congenital ptosis hospitalized in ZhongshanOphthalmic Center from Jaruary to April in 2007 were randomly divided into four groups according to different surgery types and with or without post surgery ophthalmic medica-tion. Sehirmer test, tear film break-up time , conjunctiva congestion , cornea fluorescentpigmentation , tarsal gland function , winking frequency, angle of eyelash and eyelid clo-sure were all observed and statistically analyzed in all groups 2 days , 5 days , 7 days and 2 weeks after surgery.Results : Except 3 patients needed advanced ophthalmic medicine, one of whom waswith corneal ulceration and needed another surgery, all the others were observed withocular surface items altered in varied degrees and gradually returned to normality as theinflammation caused by surgery recovered. Break-up time , winking frequency and eyelid closure were statistically diferent between the two types of surgery but not betweengroups with and without post surgery ophthalmic medication. Cornea fluorescent pigmen-tation was statistically different between groups with and without post surgery ophthalmicmedication but not between the two types of surgery. The other items did not have statis-tical difference in all groups.Conclusion : The two types of surgery for ptosis correction could alter the ocular surface ,but frontalis suspension affect tear film break-up time , winking frequency and eyelid clo-sure much more than levator advancement. Ophthalmic medication after the surgerycould only ameliorate cornea fluorescent pigmentation but was not necessarily to restora-tion of normal ocular surface. Abnormality of eyelash angle was the most dangerous fac-tor to the corea injury.
目的:探讨眼铁质沉着症(ocularsiderosis)的临床特点及治疗方案。
方法:对我院2002年1月至2006年12月的64例眼铁沉着症患者进行回顾性分析。
结果:56例手术取出残留的异物，其中33例异物最大长径<2.0 mm，位于下方睫状体扁平部或锯齿缘附近26例；眼眶X光正侧位照片联合薄骨位照片异物显影阳性率76.56%，超声生物显微镜(Ultrasound biomicroscope，UBM)异物显影阳性率47.62%；晶状体前囊铁锈沉着发生率100%；继发性青光眼发生率7.69%；视网膜脱离发生率13.84%；视网膜电流图(Electroretino-gram，ERG)karpe分期亚期占7/10和I期占3/10；56例患者作了眼内异物取出，异物取出率100%，术中发现16.07%病例异物磁性消失。
结论:眼铁质沉着症残留的异物以最大长径≤2.0 mm为主，主要位于下方睫状体扁平部或锯齿缘附近；眼眶X光照片为首选的检查方，UBM可作为眼前段异物影像学检查辅助手段；ERG改变以karpe分期的Ⅲ期和期为主；玻璃体手术是取出眼内异物最有效的治疗手段。
Purpose : To study the clinical characteristics of ocular siderosis and discuss the way for treatment.Methods : Sixty-four patients (64 eyes) with ocular siderosis treated in Ophthalmic Cen-ter of Zhongshan University from January 2002 to December 2006 were retrospectivelyanalyzed.Resuls: The intraocular foreign body( IOFB)was found in 56 cases, with maximum length<2.0 mm in 33 cases; 26 eyes with foreign body located on pars plane or near the ora serrate. The positive rate of foreign body was 76.56% by orbital posteroanterior and lateral radiogram combined with Belot 's radiogram and 47.62% by ultrasound biomicroscope( UBM). The occurrence rate of iron deposits in the epithelial cells of the anterior capsule was 100% , secondary glaucoma was 7. 69% and retina detachment was 13.84% respectively.Electroretinogram (ERG) was abnormal in 10 case , 7 cases withstage Il and 3 cases with stage IV. The intraocular foreign body extraction was done in 56 cases and the success rate was 100%. The magnetism of the intraocular foreign body disappeared in 16.07% of the cases.
Conclusions : The intraocular foreign body <2.0 mm was most frequently found in ocu-lar siderosis and mainly located on pars plane or near the ora serrate. Orbital radiogram has advantage to diagnose the intraocular foreign bodies, and UBM can be used as an assistant image-related approach for checking the intraocular foreign body on the anterior segment. Most cases were in $tage lll and IV by ERG. Vitrectomy is the most effective approach to remove the intraocular foreign bodies.

Subjects and objective: To measure the quantitative pupil light reflex after unilateral ocular contusion, analyze the correlation of pupil light reflex and other tests of visual function.Methods: The pupil light reflex in 26 patients who suffered unilateral ocular contusion was tested by infrared video pupillography, psychophysical and electrophysiological tests including visual acuity, visual field, and visual evoked potentials were also tested. Pupil area, the latency and amplitude of pupil light reflex were recorded.Results: The correlation of the ratio of pupil light reflex amplitude and the differences of visual acuity between 2 eyes in 26 contusion patients was statistically significant. The correlation coefficient r was - 0.648. There were significant correlation between amplitude of pupil light reflex and median defect of visual field. The correlation coefficients r were 0.5 and 0.535. The significant correlations were found in the ratio of amplitudes between pupil light reflex and visual evoked potentials. Multiple linear regression analysis showed combining pupil light reflex amplitude and visual evoked potential amplitude could elevate the possibility of predicting visual acuity.Conclusion: Pupil light reflex amplitude measurement is superior to other pupil measurements for reflection of the changes of visual function after ocular contusion. The correlations of pupil light reflex amplitude and visual acuity, visual field, visual evoked potential are significant in the ocular contusion patient. Pupil light reflex combined with visual evoked potential could elevate the possibility of predicting visual function precisely after ocular contusion.
目的：分析眼专科医院患者突发急症现状，并探讨防控措施。方法：回顾性分析2017—2018年中山眼科中心82例突发急症事件，具体分析突发急症事件的特点、处置情况及患者转归。结果：眼专科医院中最常见的突发急症事件为药物不良反应(n=38，46.3%)，其后依次是晕厥(28.0%)、心脑血管急症(8.3%)、意外事件(6.1%)，其中药物不良反应涉及的相关药物最多见于荧光素钠注射液(n=16，42.1%)、局部神经阻滞麻醉相关药物(n=7，18.4%)。突发急症事件集中分布于工作时段8:00—18:00(n=74，91.3%)，非工作时段多见于药物不良反应(n=3，42.9%)及心脑血管急症(n=3，42.9%)。门诊是突发急症事件最常发生的场所(n=53，64.6%)，其后依次是住院病房(22.0%)、手术室(11.0%)。患者突发急症危急程度轻、中、重度分别占92.7%，4.9%，2.4%。50%的患者需要综合医院急诊人员配合抢救或至综合医院进一步诊治。结论：通过优化患者诊治流程，缩短在院时间，医护人员提高预警意识，明确各岗位潜在急症风险，可降低突发急症事件发生风险。发挥麻醉师专业优势，提高院内应急处理能力，同时签约定点综合医院急救服务，为患者提供快速、准确、高效的救护，保障患者生命安全。
Objective: To analyze the status of medical emergencies of patients in ophthalmic hospitals and put forward suggestions on their prevention and control measures. Methods: The medical emergencies of 82 patients in ophthalmic hospitals in 2017 and 2018 was been analyzed retrospectively, and the characteristics and treatment of emergencies as well as the metastasis and progression of the disease in patients were analyzed specifically.Results: Medical emergencies were caused by druginduced adverse reaction (n=38, 46.3%), syncope (28.0%), cardiovascular emergency (8.3%), accidents (6.1%) in sequence. Fluorescein sodium (n=16, 42.1%) and local anesthesia drugs for nerve block (n=7, 18.4%) were the most common drugs related to drug adverse reaction. Most cases happened at 8:00—18:00 (n=74, 91.3%), and drug adverse reaction and cardiovascular and cerebrovascular emergencies were most common at 18:00—8:00. Medical emergencies happened in outpatient department (n=53,64.6%), wards (22.0%) and operation rooms (11.0%). There were mild emergencies (92.7%), moderate emergencies (4.9%) and severe emergencies (2.4%) in patients. Among them, 50% of patients need first aid by doctors from general hospitals or to be transferred to the general hospital for further treatment. Conclusion: Through optimizing process, shortening the hospital stay, identifying potential risks and enhancing medical workers’ awareness of safety, the risk of medical emergencies can be reduced. We should give full play to the professional advantages of anesthesiologists,improve the emergency handling capacity of the hospital, and contract the emergency services of designated general hospitals to provide rapid, accurate and efficient rescue for patients to ensure the life safety of patients.
