原发性青光眼作为慢病需要终生接受眼保健服务。本文重点介绍近年来美国青光眼协会依据标准化自动视野检查结果制定的基于ICD-9的青光眼分期诊断编码标准,该标准将青光眼分为轻度、中度、重度。国内一些医疗单位的PACS系统曾将青光眼视盘损害分为早、中、晚3期5级。目前尚缺乏视盘损害分期与上述视野损害分期对应关系的研究。青光眼损害分期诊断的研究具有重要的临床及社会学意义,它有利于眼科医师对患者区别治疗与评价治疗手段的有效性,有利于改善医患对青光眼病情的交流沟通,有利于卫生主管部门、医疗保险机构制定合理的青光眼防治策略及费用支付方案。(眼科,2014,23: 6-8) 相似文献

AIM: To detect early glaucoma by optical coherence tomography (OCT) posterior pole asymmetry analysis.
METHODS: Totally 39 eyes from 39 healthy subjects, 40 eyes from 40 mild glaucoma patients, 33 eyes from 33 moderate glaucoma patients and 41 eyes from severe glaucoma patients were included in this study. All subjects underwent posterior pole asymmetry analysis (PPAA) of OCT and the posterior pole area was divided into three zones. Means, standard deviations and 95% confidence intervals of each zone asymmetry in control group were assessed. Retina thickness asymmetry (RTA) of different stage of glaucoma were compared for each zone, and receiver operating characteristic (ROC) curves were made to test the efficacy of strategies using different zones to discriminate glaucomatous eyes from the healthy ones.
RESULTS: In a healthy population, RTA of the centre zone showed the minimal mean value (3.085 μm), standard deviation (1.756), and the narrowest 95% confidence interval (from 2.360 to 3.810 μm). It was only in the center zone that RTA exhibited significant difference between control and moderate glaucoma group (P<0.01), as well as control and severe glaucoma group (P<0.00001). The strategy utilized in the center zone had the strongest diagnostic capability (zone 3 AUROC=0.816, P=0.0016) in comparison to that of the periphery area (zone 1 AUROC=0.675, P=0.0016; zone 2 AUROC=0.623, P=0.0197), the whole posterior pole involved interpreting strategy showed inferior diagnostic power than the centre zone dependent strategy (z=2.851, P=0.0044).
CONCLUSION: Utilizing the posterior pole centre zone to interpret OCT PPAA results are more effective than making use of the whole posterior pole map. 相似文献

Purpose It was the aim of this study to investigate the efficacy, longevity, and safety of a new ab interno intervention for the treatment
of primary open-angle glaucoma (POAG).
Methods The previously described method of radiofrequency-mediated “sclerothalamotomy ab interno” was applied in 53 eyes of consecutive
patients with POAG between April 2002 and July 2002. Average preoperative intraocular pressure (IOP) was 25.6±2.3 mmHg (range
18–48 mmHg). Sclerothalamotomies were carried out with a custom-made high-frequency dissection 19 G probe (tip 0.3×1 mm) applying
bipolar current with a frequency of 500 kHz (tip temperature 130°C).
Results After a follow-up period of 24 months, the average IOP was 15.0±1.6 mmHg (range 11–20 mmHg) ( p<0.005). The average number of topical agents was 2.6±1.0 (range 1–5) preoperatively. Twenty-four months after surgery such
agents were used in only five (9.6%) eyes and the average was 0.21±0.53 (range 0–2). Transient IOP elevation was observed
in 12 of 53 eyes (22.6%) postoperatively. In all cases elevated IOP could efficiently be controlled with topical medication.
In general, IOP dropped continuously over the course of the 6 months following surgery and then remained constant.
Conclusions This study indicates that sclerothalamotomy ab interno is a safe and efficient surgical method for the treatment of POAG.
Long-term results clearly demonstrate the longevity of IOP reduction. 相似文献

The evaluation of the appearance of the optic disk is central to the diagnosis and management of patients with glaucoma. Grouping patients into categories, monitoring change, and quantitating the rate of change all require some type of quantitative staging of the amount of damage. Though the scientific literature regarding the appearance of the optic disk in glaucoma is extensive, there is remarkably little about quantitative staging of the amount of damage. We have identified eight systems, including the cup/disk ratio system of Armaly. Most of the earlier systems suffer from a failure to take into account the importance of the size of the optic disk. Furthermore, only one system includes early amounts of damage. This review is a critical appraisal of the known methods for staging optic disk damage in glaucoma, including the recent Disk Damage Likelihood Scale, which appears to offer substantial advantages over the other systems. 相似文献

青光眼随诊时采用系列眼底照相、计算机图像配比法是发现与追踪视盘出血(dischemorrhages,DH)及其相关改变的较好方法。观察DH对于青光眼病情随访、调整目标眼压及其他治疗方案具有重要意义。目前认为,DH是青光眼视网膜神经纤维层缺损加重及视野损害进展的重要危险因素,甚至认为是青光眼病情进展的先兆体征或标志。它可能是青光眼治疗不充分或未达到目标眼压的指征,对此应密切进行视神经形态与视野随访,并及时实施有效的降眼压治疗。(国际眼科纵览,2012,36:289—292) 相似文献

既往流行病学结果证明,除白内障以外,青光眼是世界第二大主要的致盲眼病,其中原发性开角型青光眼发病率高,发病机制复杂多样,且发展缓慢,病情隐匿,早期大多数无明显症状,大多数患者就诊时已进入中晚期,出现了不可逆的视功能损伤,对家庭、社会危害极大.因此,早发现、早治疗,防止视功能的进一步损伤是开角型青光眼防治的重中之重.近年来该病患病率在临床上所占的比例逐年上升,相应的诊断及治疗的新方法层出不穷.然而不论早期或是中晚期患者,降低眼压、将眼压控制在目标眼压范围,延缓视功能损害依旧是治疗的最终目标,本文将对近年来对原发性青光眼的诊疗现状及进展做一综述. 相似文献

Purpose: Globally, particularly in Africa, poor compliance with medication is a major problem in glaucoma management but little is known about follow-up rates among African glaucoma patients. The aim of this study was to determine rates of follow-up among glaucoma patients attending a tertiary hospital in southern Nigeria and investigate predictors of poor follow-up. Methods: Data were extracted from medical records of new glaucoma patients who attended the hospital between June 2011 and May 2013. Socio-demographic and clinical parameters (visual acuity; stage of glaucoma) recorded at diagnosis were extracted using a pre-tested form. Follow-up was defined as good if they had attended within 9 months of the study date, inadequate when the last follow-up was more than 9 months and failed if they did not attend any follow-up or the most recent visit was more than 14 months from the study date. Univariate and multivariable analyses were undertaken to explore predictors of poor follow-up (inadequate plus failed). Results: Three hundred forty-eight patients were recruited, 54% were male and the mean age was 52.7 (range 16–88) years. Follow-up was as follows: good 28.4%, inadequate 46.6%, failed 25%. Overall, 71.6% had poor follow-up. Independent predictors of poor follow-up were poorer visual acuity (OR 3.85, 95% confidence interval (CI) 1.25–11.80 for visual impairment; OR 4.11, 95% CI 1.32–12.81 for blind) and end-stage glaucoma (OR 3.55 (1.31–9.62), p = 0.01). Conclusion: Enhanced counselling of patients with moderate to advanced glaucoma and visual impairment is required to improve follow-up and hence glaucoma management. 相似文献

In this scoping review, we examine underlying causes of loss to follow-up for chronic (glaucoma) and acute (corneal ulcers) eye conditions using the Penchansky and Thomas access to care framework. We explore barriers by World Health Organization income levels and by studying geographical location. We identified 6,363 abstracts, with 75 articles retrieved and 16 meeting inclusion criteria. One article discussed barriers to follow-up care for people with corneal ulcers, and the other 15 were for people with glaucoma. The most frequent barriers to care were affordability, awareness, and accessibility. The international studies had a greater percentage of studies report acceptability as a barrier to loss to follow-up. Countries with universal healthcare included affordability as a loss to follow-up barrier, emphasizing that cost goes beyond the ability to pay for direct treatment costs. Understanding and addressing barriers to follow-up care can aid the goal of continued care and decrease the risk of poor outcomes and vision loss. 相似文献

Background : Fistulising trabeculotomy has been used for nearly 20 years to combine the minimally invasive surgery of trabeculotomy with production of a subconjunctival fistula. Methods : The canal of Schlemm was unroofed 2mm on one side of a 3mm half-thickness scleral flap. A trabeculotomy probe was passed about 30° along the canal on the opposite side and rotated into the anterior chamber. Results : Of 99 eyes of 74 patients, 35 eyes of 25 patients were available for follow-up at 10 or more years. The mean IOP was 14 ± 4 mmHg (range 7 to 23 mmHg) from a preoperative IOP of 29 ± 8 mmHg (17 to 60 mmHg). Results in 44 similar patients undergoing trabeculectomy and 44 undergoing fistulising trabeculotomy were very similar at five-year follow-up. Conclusion : Fistulising trabeculotomy was effective for lowering intraocular pressure with a low complication rate and a large area of subconjunctival fistulisation. 相似文献

AIM: To assess glaucoma patient satisfaction and follow-up adherence in case management and identify associated predictors to improve healthcare quality and patient outcomes.
METHODS: In this cross-sectional study, a total of 119 patients completed a Patient Satisfaction Questionnaire-18 and a sociodemographic questionnaire. Clinical data was obtained from the case management system. Follow-up adherence was defined as completing each follow-up within ±30d of the scheduled time set by ophthalmologists during the study period.
RESULTS: Average satisfaction scored 78.65±7, with an average of 4.39±0.58 across the seven dimensions. Age negatively correlated with satisfaction (P=0.008), whilst patients with follow-up duration of 2 or more years reported higher satisfaction (P=0.045). Multivariate logistics regression analysis revealed that longer follow-up durations were associated with lower follow-up adherence (OR=0.97, 95%CI, 0.95-1.00, P=0.044). Additionally, patients with suspected glaucoma (OR=2.72, 95%CI, 1.03-7.20, P=0.044) and those with an annual income over 100 000 Chinese yuan demonstrated higher adherence (OR=5.57, 95%CI, 1.00-30.89, P=0.049).
CONCLUSION: The case management model proves effective for glaucoma patients, with positive adherence rates. The implementation of this model can be optimized in the future based on the identified factors and extended to glaucoma patients in more hospitals. 相似文献

AimTo compare the diagnostic performance of accredited glaucoma optometrists (AGO) for both the diagnosis of glaucoma and the decision to treat with that of routine hospital eye care, against a reference standard of expert opinion (a consultant ophthalmologist with a special interest in glaucoma). MethodsA directly comparative, masked, performance study was undertaken in Grampian, Scotland. Of 165 people invited to participate, 100 (61%) were examined. People suspected of having glaucoma underwent, within one month, a full ophthalmic assessment in both a newly established community optometry led glaucoma management scheme and a consultant led hospital eye service. ResultsAgreement between the AGO and the consultant ophthalmologist in diagnosing glaucoma was substantial (89%; κ = 0.703, SE = 0.083). Agreement over the need for treatment was also substantial (88%; κ = 0.716, SE = 0.076). The agreement between the trainee ophthalmologists and the consultant ophthalmologist in the diagnosis of glaucoma and treatment recommendation was moderate (83%, κ = 0.541, SE = 0.098, SE = 0.98; and 81%, κ = 0.553, SE = 0.90, respectively). The diagnostic accuracy of the optometrists in detecting glaucoma in this population was high for specificity (0.93 (95% confidence interval, 0.85 to 0.97)) but lower for sensitivity (0.76 (0.57 to 0.89)). Performance was similar when accuracy was assessed for treatment recommendation (sensitivity 0.73 (0.57 to 0.85); specificity 0.96 (0.88 to 0.99)). The differences in sensitivity and specificity between AGO and junior ophthalmologist were not statistically significant. ConclusionsCommunity optometrists trained in glaucoma provided satisfactory decisions regarding diagnosis and initiation of treatment for glaucoma. With such additional training in glaucoma, optometrists are at least as accurate as junior ophthalmologists but some cases of glaucoma are missed. 相似文献
