目的：探讨珠海地区早产儿视网膜病变（retinopathy of prematurity，ROP）的患病情况及临床特点。方法：回顾分析珠海市妇幼保健院2009年5月至2018年12月 5 473 例（10 946 只眼）早产儿的眼病筛查资料。结果：共筛查出 185 例（370 眼）患有不同程度的 ROP，患病率为 3.38%。33 例（66 眼）需要治疗，占 17.84%。低出生体重组出生孕周为 26～31，32～33，34～36的 ROP 患儿分别为 133，13，9 例，ROP 发病率分别为 14.9%，1.4%，1.3%，差异具有统计学意义（P < 0.05）。高出生体重组出生孕周为 26～31，32～33，34～36 的 ROP 患儿分别为 1，5，24例，ROP 发病率分别为 7.1%，1.1%，1.0%，差异无统计学意义（P > 0.05）。33 例严重 ROP 患儿（需要干预治疗的 ROP）中，低出生体重组出生孕周为 26～31，32～33，34～36 的严重ROP患儿分别为 29，3，1 例，发病率分别为 3.2%，3%，0.1%，差异具有统计学意义（P < 0.05）。高出生体重组无严重 ROP 患儿。结论：珠海地区近十年的早产儿 ROP 患病率为 3.38%，出生体重和胎龄是 ROP 发病的危险因素。严重ROP患儿的出生体重均 <2 000 g。

Objective: To investigate the clinical characteristics of retinopathy of prematurity (ROP) in Zhuhai. 

Methods: The eye screening data for 5,473 (10,946 eyes) premature infants born from May 2009 to December 2018 in the Maternal and Child Health Hospital of Zhuhai were retrospectively analyzed.

Results: In the 5 473 premature babies examination, 185 cases (3.38%) were detected with different degrees of ROP. The number of cases requiring treatment was 33 (17.84%). In the low birth weight group, the ROP patients with 26–31, 32–33, and 34–36 weeks were 133 (14.9%), 13 (1.4%), and 9 (1.3%), respectively; the difference was statistically significant (P < 0.05). In the high birth weight group, the ROP patients with birth weeks of 26–31, 32–33, and 34–36 were 1 (7.1%), 5 (1.1%), and 24 (1.0%), respectively; the difference was not statistically significant (P > 0.05). Among the 33 children with severe ROP (requiring intervention treatment), there were 29 (3.2%), 3 (3%), and 1 (0.1%) with birth weeks of 26–31, 32–33, and 34–36, respectively, in the low birth weight group; the difference was statistically significant (P < 0.05). The severe ROP was 0 in the high birth weight group.

Conclusion: The prevalence of ROP in premature infants is 3.38% in the past decade in Zhuhai. Birth weight and gestational age are risk factors for ROP. The birth weight of infants with severe ROP is less than 2 000 g.

      原发性玻璃体视网膜淋巴瘤(primary vitreoretinal lymphoma, PVRL)作为原发性中枢神经系统淋巴瘤(primary central nervous system lymphoma，PCNSL)的一个亚型，是一种罕见的致命性眼部恶性肿瘤。多数PVRL会伪装成慢性后葡萄膜炎，这使得临床诊断具有挑战性。玻璃体细胞、视网膜下液和影像学检查对临床诊断至关重要。而对恶性细胞的细胞学检查与组织病理学诊断是PVRL诊断的金标准。此外，免疫球蛋白重链(immunoglobulin heavy chain, IgH)或T细胞受体(Tcell receptor, TCR)基因重排的分子生物学检测、细胞标志物的免疫表型检测、以及细胞因子检测如IL-10的表达升高均可作为辅助诊断工具。目前PVRL的治疗主要包括局部放射及玻璃体腔内注射化疗药物(甲氨蝶呤和利妥昔单抗)，根据眼外组织是否受累决定是否联合全身化疗。对伴随PCNSL的患者，在全身大剂量甲氨蝶呤联合利妥昔单抗治疗的基础上，考虑联合局部治疗、全脑放疗和/或自体干细胞移植。尽管PVRL对初始治疗反应良好，但因其复发率高，常出现CNS受累，使PVRL的生存期预后较差。因此建立一个包含眼科医师、眼科病理学家、神经肿瘤学家以及血液肿瘤学家在内的专业团队来优化患者的治疗方案显得尤为重要。

目的：检测 2 型糖尿病患者眼房水中血管内皮生长因子（Vascular endothelial growth factor, VEGF）和白细胞介素-6（Interleukin-6, IL-6）的含量，并探讨其临床意义

方法：在白内障手术过程中获取 66 例 2 型糖尿病患者的房水，采用双抗体夹心酶联免疫吸附（ELISA）法测定 VEGF 和 IL-6 的含量。根据手术后散瞳眼底检查和眼底荧光素血管造影检查确定糖尿病视网膜病变的分期。实验组分为：无糖尿病视网膜病变组（NDR）21 例、单纯型糖尿病性视网膜病变组（BDR）26 例、增生型糖尿病性视网膜病变组（PDR）19 例，正常对照组为健康的老年性白内障患者 20 例。

Purpose: To explore the role of vascular endothelial growth factor (VEGF) and interleukin-6 (IL-6) in the aqueous humor in the pathogenesis of diabetic retinopathy (DR).

Methods: Aqueous humor samples were collected in type 2 diabetic patients during cataract surgery. The classification of DR was assigned based on the fundus examination and fluorescein angiography after cataract surgery. The experiment group included non-diabetic retinopathy (NDR, 21 cases), background diabetic retinopathy (BDR, 26 cases), and proliferative diabetic retinopathy (PDR, 19 cases). The control group was the healthy cataract patients (20 cases). The levels of VEGF and IL-6 in the aqueous humor were assessed using the ELISA technique.

Results: The level of VEGF in NDR, BDR, and PDR cases were (240.30 ± 26.15) pg/ml, (292.27 ± 58.91) pg/ml, and (477.41 ± 91.01) pg/ml, respectively. The level of IL-6 in NDR, BDR, and PDR cases were (160.83 ± 33.41) pg/ml, (238.60 ± 62.23) pg/ml, and (389.13 ± 90.35) pg/ml, respectively. The levels of VEGF and IL-6 in the aqueous humor from the control group were (140.58 ± 26.27) pg/ml, (82.72 ± 21.53) pg/ml. The levels of VEGF and IL-6 were significantly different in experiment and control groups (F = 113.67, P < 0.01; F = 106.53, P < 0.01). In the aqueous humor of diabetic patients increased significantly (P < 0.1). The levels of VEGF and IL-6 were significantly correlated with each other in the experiment group (r = 0.995, P < 0.01). The levels of VEGF (r = 0.792, 0.826, 0.841, P < 0.01) and IL-6 ((r = 0.829, 0.817, 0.896, P < 0.01) were also significantly correlated with the duration of DR.

Conclusion: VEGF and IL-6 play important roles in the development of DR. The levels of these two factors are correlated with each other in DR patients.

The total effectiveness in the study group was 89.9%, in the control group was 75.6%, the difference was statistically significant (χ²=6.302, P=0.012). Conclusion: The whole retinal laser photocoagulation and postoperative application of calcium dobesilate in treating the diabetic retinopathy can effectively improve eyesight and clinical curative effect, which may be associated with improving blood rheology.

目的：研究基质金属蛋白酶-2（Matrix metalloproteinase-2, MMP-2）、基质金属蛋白酶-9（Matrix metalloproteinase-9, MMP-9）和血管内皮生长因子（Vascular endothelial growth factor, VEGF）在视网膜母细胞瘤（Retinoblastoma, RB）中的表达及其与 RB 分化程度和视神经浸润的关系，探讨它们在 RB 浸润、转移过程中的作用和临床意义。

方法：采用免疫组化方法检测 40 例 RB 中 MMP-2、MMP-9 和 VEGF 的表达。

结果：40 例 RB 中 MMP-2、MMP-9 和 VEGF 的阳性表达率分别为 52.5%、57.5% 和 72.5%。未分化型 RB 中 MMP-2、MMP-9 和 VEGF 的阳性表达均高于分化型（P < 0.05）；有视神经浸润的 RB 中 MMP-2、MMP-9 和 VEGF 的阳性水平均高于无视神经浸润的 RB（P < 0.05）。RB 中 MMP-2、MMP-9 和 VEGF 的表达呈正相关关系（P < 0.05）。

结论：RB 中 MMP-2、MMP-9 和 VEGF 高表达与 RB 的浸润和转移相关，且 MMP-2、MMP-9 表达与 VEGF 表达存在相关性。联合检测 MMP-2、MMP-9 和 VEGF 的表达可作为反映 RB 浸润、转移潜能的生物学指标，有助于筛选转移高危病例及评价患者预后。

Purpose: To study the expression of matrix metalloproteinase-2 (MMP-2), matrix metalloproteinase-9 (MMP-9) and vascular endothelial growth factor (VEGF) in retinoblastoma (RB) and its relationship with the differentiation and optic nerve infiltration of RB. And to investigate the role of matrix metalloproteinase-2 (MMP-2), matrix metalloproteinase-9 (MMP-9) and VEGF in the infiltration and metastasis of RB and their clinical significance.

Methods: Immunohistochemical technique was used to detect the protein expression of MMP-2, MMP-9 and VEGF in 40 RB cases.

Results: The MMP-2, MMP-9 protein and VEGF protein expression were detected as positive in 52.5%, 57.5% and 72.5% of 40 RB cases respectively. The expression of MMP-2, MMP-9 and VEGF was significantly higher in the undifferentiated pattern than in the rosetted pattern (p < 0.05); and the expression of MMP-2, MMP-9 and VEGF was significantly higher in tumors with optic nerve invasion than in those without optic nerve invasion (p < 0.05). In RB, the expression of MMP-2, MMP-9 had a positive correlation with the expression of VEGF.

Conclusions: In RB, high expression of MMP-2, MMP-9 and VEGF is related to the invasion and metastasis of RB. The expression of MMP-2, MMP-9 is positively correlated with the expression of VEGF. The expression of MMP-2, MMP-9 and VEGF may act as a biological marker for the invasion and metastasis of RB. The method may help screen and identify the cases with high risk for metastasis and to predict the prognosis of patients.

结论:增殖性糖尿病患者玻璃体 SDF-1 和 VECF 的含量均高于非糖尿病患者,提示 SDF-1 和 VEGF 共同参与了增殖性糖尿病视网膜病变患者病理性新生血管的形成过程。

Purpose: To investigate the levels of stromal cell-derived factor-1(SDF-1) andvascular endothelial growth factor (VEGF) in the vitreous of patients with proliferativediabetic retinopathy.
Methods: The levels of $DF-1 and VEGF in the vitreous of 30 eyes of 30 patients withproliferative diabetic retinopathy(PDR)and 12 eyes of 12 patients with idiopathicmacular hole (MH) were measured by enzyme-linked immunosorbent assay. Vitreousfluid samples were obtained by vitrectomy.
Resuls: The vitreous concentration of VEGF was signifcantly higher in eyes with PDR(2 865.87+387.85 pg/ml) than in eyes with idiopathic macular hole (142.42+21.03 Pgml, P< 0.000 1). The vitreous level of SDF-1 was also significantly higher in eyes withPDR (298.40+24.57 pg/ml ) than in eyes with idiopathic macular hole (86.91+15.89Pg/ml, P<0.000 1 ). The vitreous concentration of SDF-1 correlated significantly with that of VEGF in eyes with PDR( [correlation coefficient]r=0.62,P<0 .001)
Conclution: Vitreous levels of both SDF-1 and VEGF in patients with PDR aresignificantly higher than those of nondiabetic patients. SDF-1 may be correlated withVEGF in angiogenesis in PDR.

结果: 15 只眼发生裂孔源性视网膜脱离(6.4%) , 均需行玻璃体视网膜手术进行视网膜复位。从白内障手术到发生视网膜脱离的平均时间为10 ± 9 个月(0.5～32 个月) 。视网膜脱离经手术治疗后视力为手动 /10 cm～0.06, 12 只眼(80%) 最终视力低于白内障术前。术中后囊膜破裂与术后视网膜脱离的发生显著相关 (P < 0.01) , 60%(9/15) 的视网膜脱离患者术中发生了后囊膜破裂。

结论: 高度近视眼白内障术后并发裂孔源性视网膜脱离的发生率为 6.4%, 其预后差。术中发生后囊膜破裂患者术后发生视网膜脱离的危险性更高, 对术中后囊膜破裂患者需密切随访。

Aim: To analyze the clinical characteristics, incidence and risk of retinal detachment (RD) after cataract surgery and posterior chamber intraocular lens implantation in high myopic patients.

Methods:The medical records of 146 high myopic patients (232 eyes) who underwent cataract surgery and posterior chamber intraocular lens implantation were studied retrospectively. The development of RD was followed up over a 3-year period, and its characteristics were determined. All of the eyes received a comprehensive ophthal-mological examination, including best-corrected visual acuity measurements, a dilated fundus examination and axial length measured by A-scan ultrasonography.

Results: RD developed in 15 eyes of 15 patients. All the 15 eyes needed vitreo-retinal surgery. The mean interval between cataract surgery and the development of RD was 10 ± 9 months (range 0.5～32 months) . The visual results of the eyes after anatomical successful vitreo-retinal surgery ranged from finger count /10 cm to 0.06. 80% (12/15) of the eyes had a worse vision after the surgery than that before cataract surgery. Posterior capsular tear were associated significantly with RD (P < 0.01). Approximately 60%( 9/15) of retinal detachment was attributable to posterior capsule tear during cataract surgery.

Conclusion: Incidence of RD in high myopic patients after cataract surgery was 6.4%. RD was the potentially serious complication and tended to develop more frequently in eyes with posterior capsular rupture during cataract surgery. It is crucial to examine retinal status after cataract surgery and to have a close follow-up to prevent retinal complications, especially for patients with posterior capsular disruption.
