近视性黄斑病变的分类进展和诊治现状

Advances in classification, diagnosis and treatment of myopic maculopathy

:219-226
 
近视性黄斑病变(myopic maculopathy,MM)是近视最常见的并发症,也是影响病理性近视视功能下降的主要原因。目前,MM的分类系统尚不能完全解释患者黄斑部发生的多种变化,迫切需要一个全面、统一的分类系统来协助沟通和比较临床试验以及国际多中心研究的结果。随着眼底成像技术的发展与应用,最新的近视性黄斑病变分类,即ATN分类系统[萎缩(A)、牵拉(T)、和新生血管(N)]结合眼底照片与光学相干断层扫描(optical coherence tomography,OCT)图片,把黄斑病变分为3类,每一类又根据其严重程度进行分级,这对MM的诊断和治疗提供了较大的临床价值。
Myopic maculopathy (MM) is the most common complication of myopia, which is also the main cause of poor visual function in pathologic myopia. Presently, the classification system of MM cannot properly explain the numerous changes that occur in the patient’s macula. Therefore, a comprehensive and unified classification system is urgently needed to facilitate in communicating and comparing the results of clinical trials and international multicenter studies. With the development and application of fundus imaging technology, the latest classification of MM, namely ATN (atrophy, A; traction, T; neovascularization, N) classificationsystem, which combines fundus photographs and optical coherence tomography (OCT) images, classifies macular lesions into 3 categories according to its severity, generating greater clinical value for the diagnosis and treatment of MM.

2型糖尿病视网膜病变严重程度与血清生化全套指标的相关性

Correlation between the severity of type 2 diabetic retinopathy and the serum biochemical indexes

:200-204
 
目的:分析不同程度2型糖尿病视网膜病变的血清生化全套指标,探讨各生化指标与糖尿病性视网膜病变(diabetic retinopathy,DR)程度的相关性。方法:回顾性收集2018年5月至2020年10月在福建医科大学附属第二医院就诊的2型糖尿病患者。根据眼底情况分为3组:糖尿病不伴视网膜病变(non-diabetic retinopathy,NDR)组(17例)、糖尿病伴非增殖性视网膜病变(non-proliferative diabetic retinopathy,NPDR)组(29例)、糖尿病伴增殖期视网膜病变(proliferative diabetic retinopathy,PDR)组(34例)。采用SPSS 24.0分析比较3组血清生化全套各指标水平,对差异指标与DR相关性采用Pearson相关分析与多重线性回归分析。结果:3组年龄差异无统计学意义(P>0.05);3组的总蛋白、白蛋白、白球比、钙浓度差异均有统计学意义(均P<0.05)。组间比较发现NPDR和PDR组总蛋白、白蛋白、白球比、钙浓度低于NDR组,差异有统计学意义(P<0.05)。Pearson相关分析显示总蛋白(r=?0.290)、白蛋白(r=?0.304),钙浓度(r=?0.252)与DR呈负相关(均P<0.05),多重线性回归提示总蛋白、白蛋白及血钙浓度是DR保护因素(P<0.05)。结论:血清指标总蛋白、白蛋白及血钙浓度与DR成负相关,在生理范围内将这些指标维持相对较高的水平,或许可以为糖尿病视网膜病变的防治提供新思路。
Objective: To analyze the serum biochemical indexes of different degrees of type 2 diabetic retinopathy, and the correlation between biochemical indexes and the degree of diabetic retinopathy (DR). Methods: Patients with type 2 diabetes admitted to the Fujian Medical University 2nd Affiliate Hospital from May 2018 to October 2020 were retrospectively collected. The patients were divided into 3 groups according to fundus conditions: non-diabetic retinopathy (NDR) group (n=17), diabetes with non-proliferative diabetic retinopathy (NPDR) group (n=29),diabetes with proliferative diabetic retinopathy (PDR) group (n=34). SPSS 24.0 was used to compare the levels of a complete set of serum biochemical indexes in the three groups. Pearson correlation analysis and multiple linear regression analysis were used for the correlation between the different indexes and DR. Results: There was no statistically significant difference in age between the three groups. The differences in total protein, albumin, white sphere ratio, and calcium concentration of the three groups were statistically significant (P<0.05). The comparison between the groups showed that the total protein, albumin, white sphere ratio, and calcium concentration in the NPDR and PDR groups were lower than those in the NDR group. The difference was statistically significant (P<0.05). Pearson correlation analysis showed that total protein (r=?0.290), albumin (r=?0.304), and
calcium concentration (r=?0.252) were negatively correlated with DR (all P<0.05). Multiple linear regression indicated total protein, albumin and blood calcium concentration were the protective factors of DR (P<0.05).Conclusion: This study found that serum levels of total protein, albumin, and blood calcium levels are negatively correlated with DR. Maintaining a relatively high level of these indexes within the physiological range may provide new ideas for the prevention and treatment of diabetic retinopathy.

三叉神经鞘瘤并发神经麻痹性角膜炎一例

Trigeminal schwannoma complicated with nerve paralysis keratitis: a case report

:360-363
 
该文报道一例中年男性患者,因“头痛伴左侧听力下降”就诊于我院神经外科,经影像学检查诊断为“左侧三叉神经鞘瘤”, 手术前实验室检查发现血象异常,经血液科会诊后诊断为多发性骨髓瘤IgDλ型,于化疗期间并发神经麻痹性角膜炎(neurotrophic keratitis,NK),可于角膜中央偏下方的上皮及前基质层见到类圆形的灰白色浑浊,呈胶冻样,经局部药物治疗后好转,但残留角膜基质白色浑浊。由于现阶段临床对NK尚欠缺充分认识,易延误诊治,并且本文报道的此例NK患者,因其有化疗病史且于治疗期间出现相关体征,易被误诊为化疗并发细菌性角膜炎,文章通过分析其角膜病变的特征及简单回顾NK的临床特征、鉴别诊断及治疗,以期临床早期识别及治疗此类患者,恢复角膜的光学特性,维持良好的视觉体验。
Tis article reports a case of a middle-aged male patient who visited the Department of Neurosurgery of our hospital due to headache and lef hearing loss. He was diagnosed with lef trigeminal schwannoma by imaging examination and abnormal blood routine before surgery. During chemotherapy and paralytic keratitis (neurotrophic keratitis, NK), can be seen in the lower part of the corneal center of the epithelium and the prestromal layer of round gray and white turbidities, jelly like, afer local drug treatment improved, but residual corneal stromal white turbidities. Due to the lack of full understanding of NK in clinic at the present stage, diagnosis and treatment is easy to be delayed. In addition, the NK patient reported in this paper was easily misdiagnosed as bacterial keratitis complicated by chemotherapy due to his history of chemotherapy and related signs during treatment. Tis paper analyzed the characteristics of keratopathy and briefy reviewed the clinical characteristics, diferential diagnosis and treatment of NK, in order to identify and treat these patients in early clinical stage, restore the optical characteristics of cornea and maintain good visual experience.

Revisiting the upper eyelid blepharoplasty advancement flap: adaptation for the repair of full-thickness upper eyelid defects—a case series

Revisiting the upper eyelid blepharoplasty advancement flap: adaptation for the repair of full-thickness upper eyelid defects—a case series

:-
 
A blepharoplasty flap has been previously reported as a useful reconstruction approach for anterior lamellar defects lying between the lash line and the eyelid crease. We herein describe a variation of the blepharoplasty flap and suggest its use as an adjunct in the reconstruction of full-thickness lateral upper eyelid defects. Technique description and retrospective interventional case series. The reconstruction technique was used by an experienced oculoplastics surgeon (ASL) in 3 adults with malignant lesions involving the lateral upper eyelid margin, resulting in a post-excision 50% full-thickness defect between November 2017 and June 2020. The posterior lamella was reconstructed using an ipsilateral free tarsal graft and an inferiorly hinged transposition periosteal flap. The anterior lamella reconstruction was then performed using a local advancement flap utilizing the principles of upper blepharoplasty and Burow’s triangle. Almost full eyelid excursion and full gentle closure were evident at 1–2 weeks follow-up in all three cases. One case later developed 1–2 mm of gentle closure lagophthalmos and was managed successfully with topical lubricants. In all patients, the final eyelid contour and symmetry were adequate, with only minimal scarring, evident already 3 to 4 months postoperative. There were no major complications or need for revisions. The technique described herein highlights the utility of the blepharoplasty flap for lateral, full-thickness upper eyelid defects. This logical variation enables the reconstruction of significant defects using only local tissue, obeying the “like with like” principle, and helps avoid the need for a bridging flap. We provide preliminary evidence of the potential of a good cosmetic outcome of upper lid appearance and contour, together with a fast recovery of appropriate eyelid function.

人工智能在糖尿病视神经病变诊断中的应用价值

Application of artificial intelligence in the diagnosis of diabetic optic neuropathy

:-
 
目的:通过分析基于眼底彩照的人工智能(artificial intelligence,AI)在糖尿病视神经病变(diabetic optic neuropathy,DON)中的参数特征,探索AI在DON诊断中的应用价值。
方法:收集2020年1月1日至2022年4月30日就诊于东莞东华医院、横沥医院及东莞市寮步镇社区卫生服务中心并诊断为糖尿病的患者,采集其一般信息并拍摄以黄斑为中心、图片边缘距离视盘中心超过1PD的50°眼底彩照。眼底彩照由人工智能诊断系统分析获得视盘及血管检测参数,由3-4名眼底专家阅片后分为DON(+)、DON(-)两组并作糖尿病视网膜病变(diabetic retinopathy,DR)分期诊断。比较两组间视盘、血管检测参数的差异性,并分析各项参数以及DR分期与DON发病的相关性。
结果:研究共纳入糖尿病患者526人(945眼),其中男性335人,女性191人;平均年龄为51.58±12.21岁,平均病程为5.51±5.20年。所有入组病例中,DON(+)组205眼,DON(-)740眼;根据专科医师判读结果,无DR 723眼,轻度非增殖期糖尿病视网膜病变(non-proliferrative diabetic retinopathy,NPDR)7眼,中度NPDR 184眼,重度NPDR 24眼,增殖期糖尿病视网膜病变(proliferrative diabetic retinopathy,PDR)7眼。AI检测的视盘及血管参数中,水平视杯直径、垂直视杯直径、水平杯盘比、垂直杯盘比、B区视网膜静脉血管当量、B区视网膜动静脉比值在有或无DON组间存在显著差异;水平视盘直径、垂直视盘直径、弧形斑和视盘面积比、B区视网膜动脉当量在两组之间无显著差异。相关性分析发现,水平视杯直径、垂直视杯直径、水平杯盘比、垂直杯盘比、B区视网膜动静脉比值与DON患病呈负相关;B区视网膜静脉血管当量、DR分期则与其呈正相关。
结论:DON患者的视杯直径、杯盘比、B区视网膜静脉血管当量等基于眼底彩照的人工智能检测参数有显著改变;DON的发病与DR病变严重程度有关。
Objective: To explore the application value of artificial intelligence (AI) in the diagnosis of diabetic optic neuropathy (DON) by analyzing the parameter characteristics of artificial intelligence (AI) based on fundus color photos.
Methods: From January 1, 2020 to April 30, 2022, patients diagnosed with diabetes were collected in Dongguan Donghua Hospital, Hengli Hospital of Dongguan and Community Healthcare Center of Dongguan Liaobu. General information was collected and 50°field vision fundus images(centered on macula and the edge of the images were more than 1PD away from the center of the optic disc) were taken. All the images were divided into DON(+) and DON(-) groups by 3-4 ophthalmologists. All the parameters were detected and analyzed by AI system, and their differences between the two groups were compared. The correlation between each parameter and DR stage with the incidence of DON was analyzed as well.
Results: A total of 526 diabetic patients (945 eyes) were included in this study, including 335 males and 191 females. The mean age was 51.58±12.21 years, and the mean disease duration was 5.51±5.20 years. All the enrolled cases were divided into DON (+) group (205 eyes) and DON (-) group (740 eyes) . According to ophthalmologists’ interpretation, 723 eyes had no DR, 7 eyes had mild nonproliferrative diabetic retinopathy (NPDR), 184 eyes had moderate NPDR, 24 eyes had severe NPDR, 7 eyes had Proliferrative diabetic retinopathy (PDR). Among the parameters detected by AI, there were significant differences in horizontal and vertical optic cup diameter, horizontal and vertical C/D, retinal vein equivalent(RVE) in zone B, and retinal arteriole-to venule ratio(AVR) in zone B between DON(+) and DON(-) groups. There were no significant differences between the two groups in horizontal and vertical optic disc diameter, arc-shaped spot-to-disc area ratio, and retinal artery equivalent(RAE) in zone B. In the analysis of risk factors, horizontal and vertical optic cup diameter, horizontal and vertical C/D, and AVR in zone B were negatively correlated with the diagnosis of DON. RVE in zone B and the severity of DR were positively correlated with the diagnosis of DON.
Conclusions: The AI detection parameters based on fundus color photography have significant changes in the diameter of optic cup, C/D and RVE in zone B in DON patients. The incidence of DON is related to the severity of DR.

光学相干断层扫描成像对急性中心性浆液性脉络膜视网膜病变渗漏点的前瞻性观察研究

Observation on the leakage point of acute central serous chorioretinopathy through optical coherence tomography: A prospective study

:115-121
 
目的:观察急性中心性浆液性脉络膜视网膜病变(central serous chorioretinopathy,CSC)的自然病程中渗漏点的形态及变化。方法:本研究为前瞻性研究,使用光学相干断层扫描(optical coherence tomography,OCT)观察从发病到发病后5~13个月的CSC患者的渗漏点的OCT形态,测量并计算Hall层、脉络膜全层各自厚度及比值,并进行比较。结果:共20例患者[男14例,女6例,年龄33~59(中位数41)岁]纳入研究。随访时间为5~13个月。在19例患者中观察到微小视网膜色素上皮脱离(pigment epithelium detachment,PED)。1例患者可见视网膜色素上皮(retinal pigment epithelium, RPE)小凸起。在随访期间,仅1例患者的PED完全恢复,其他19例患者在视网膜下液被完全吸收时,RPE和Bruch膜之间仍存在微小分离。渗漏点处的Haller层/脉络膜厚度显著高于中央凹处(初诊时0.806±0.08 vs 0.863±0.06,P=0.003;最后1次随访时为0.801±0.07 vs 0.851±0.06,P=0.004)。结论:本研究观察到在急性CSC患者自然病程中,即使视网膜下液吸收,OCT显示渗漏点处仍存在持续的PED,更厚的Haller层及更薄的内层脉络膜,这些发现为CSC的发病机制提供了更多线索。
Objective: To observe the morphology and changes of leakage points in the natural course of acute central serous chorioretinopathy (CSC). Methods: This study was a prospective study, using optical coherence tomography to observe the OCT morphology of leakage points in CSC patients from onset to 5 to 13 months after onset, measuring the thickness and ratio of Hall layer and the whole choroid, and then compare them. Results: A total of 20 patients were included in the study, including 14 males and 6 females, aged from 33 to 59, with the median being 41 years old. The follow-up time ranged from 5 months to 13 months. Minute retinal pigment epithelial detachments (PED) were observed in 19 patients. A small bulge of retinal pigment epithelium (RPE) was observed in 1 patient. During the follow-up, only one patient totally recovered. Small separation between RPE and Bruch membrane still exit even subretinal fluid were absorbed completely in the other 19 patients. The thickness of Haller layer or choroid at the leakage point was significantly higher than that of the fovea (0.806±0.08 vs 0.863±0.06, P=0.003, at the first visit; 0.801±0.07 vs 0.851±0.06, P=0.004, at the last follow-up). Conclusion: This study observed that in the natural course of acute CSC patients, even if the subretinal fluid was absorbed, OCT still showed that there was persistent PED at the leakage point, thicker Haller layer and thinner inner choroid layer. These findings provided more clues to the pathogenesis of CSC.

非器质性视力下降误诊为儿童视神经炎一例分析

Analysis of one case of non-organic visual loss misdiagnosed as optic neuritis in children

:299-304
 
非器质性视力下降也称为心因性或功能性视力下降,除视力下降外,还可伴有视野缺损,多由于精神心理疾患导致的转换障碍引起,部分患者为诈病以获取利益。本文报道1例6岁的女性患者,主诉双眼反复视力下降1年余,早期被误诊为儿童视神经炎,给予糖皮质激素冲击治疗,治疗后稍有好转。通过本例患者误诊的教训,提醒我们在遇到儿童出现不明原因的视力下降时,在没有明确器质性疾病证据时要想到非器质性视力下降的可能,掌握识别非器质性视力下降的检查方法,不能忽略相对性传入性瞳孔障碍等基础的神经眼科检查。
Non-organic vision loss is also known as psychogenic or functional vision loss. In addition to vision loss, it can also be accompanied by visual field defect. It is mostly caused by conversion obstacles caused by mental and psychological diseases. Some patients cheat to obtain benefits. This paper reports a 6-year-old female patient who complained of repeated visual acuity decline for more than one year. She was misdiagnosed as pediatric optic neuritis in the early stage and was treated with glucocorticoid shock therapy, which her condition improved slightly after treatment. The misdiagnosis of this patient teaches us that when children have unexplained visual acuity decline, we should think of the possibility of non-organic visual acuity decline when there is no clear evidence of organic diseases, master the examination methods to identify non-organic visual acuity decline, and cannot ignore the basic neuro-ophthalmic examination such as relative afferent pupillary defect (RAPD).

晶状体悬韧带与原发性闭角型青光眼之已知与未知

Lens zonulopathy and primary angle closure glaucoma:what we know and what we don't know

:140-147
 
晶状体悬韧带异常(包括松弛和断裂)可引起晶状体虹膜隔前移、前房变浅、房角关闭和眼压升高,即闭角型青光眼(angle closure glaucoma,ACG)的发生。特发性悬韧带异常多发生于原发性闭角型青光眼(primary angle closure glaucoma,PACG),可能是PACG的发病机制之一,但仍需前瞻性队列研究进一步证实。此类患者双眼前房深度不等,虹膜/晶状体震颤等体征及超声生物显微镜(ultrasound biomicroscopy, UBM)检查能够诊断的悬韧带异常比例较低,通常在青光眼白内障联合手术前未能被诊断而在术中被发现,故被称为隐匿性晶状体悬韧带异常。目前根据术中表现如充分散瞳可见晶状体赤道部,连续环形撕囊破囊时可见前囊放射状皱褶,超声乳化时囊袋赤道部移位或卷曲,灌注抽吸时囊袋异常飘动,囊袋口不规则等可明确诊断。根据悬韧带异常的程度、范围,选择超声乳化晶状体吸除联合人工晶体植入,联合或不联合囊袋张力环植入或人工晶体缝合固定术。PACG患者术前和术中应关注是否存在悬韧带异常,制定个体化治疗方案,以保证手术安全和疗效。
Zonulopathy (including zonular laxity and dehiscence) can cause anterior displacement of iris-lens diaphragm, shallow anterior chamber, anterior chamber angle closure and elevated intraocular pressure, resulting in angle closure glaucoma (ACG). Idiopathic zonulopathy is common in primary angle closure glaucoma (PACG), which may be one of the pathogenic mechanisms of PACG. But further prospective cohort studies are needed to verify that. ?e proportion of diagnosis ofzonulopathy in PACG patients before cataract extraction in combination with anti-glaucoma surgery is low by signs of anterior chamber depth differences between both eyes, iridodonesis / phacodonesis and UBM examination. Hence, most cases with zonulopathy in PACG are found during the operation, which is called occult zonulopathy. At present, the diagnosis of zonulopathy in PACG is often made according to the intraoperative manifestations, such as visible capsular equator aěer mydriasis, wrinkling of the anterior capsule during manual capsulorhexis, infolding of peripheral capsule or visualization of the capsular equator during the cortical or nuclear removal; loose or ěoppy capsular bag. According to different ranges and severities ofzonulopathy, phacoemulsi?cation combined with intraocular lens (IOL) implantation, with or without capsule tension ring implantation, or sclera-fixated IOL is selected. PACG patients should be paid more attention to the diagnosis and differentiation ofzonulopathy before and during operation, fully improved the preoperative examination, and formulated individualized treatment plans to ensure the safety and efficacy of operation.
