Objective: To analyze the demographic characteristics and biochemical indexes of type 2 diabetic patients in Han population in Hunan, and to find the high-risk factors of diabetic retinopathy. Methods: The data of demographic characteristics and biochemical indexes of normal population, type 2 diabetic patients but without retinopathy and type 2 diabetic retinopathy in Hunan were analyzed. Group t test and logistic regression analysis were used to analyze the susceptibility factors of diabetic retinopathy. All the subjects were Han population. Results: There were no significant differences in gender distribution, age distribution, BMI, diastolic blood pressure, HbA1c,total cholesterol, high-density lipoprotein, uric acid and total bilirubin between the control group [non-diabetes mellitus (NDM) group] and the type 2 diabetic without retinopathy group [non-diabetic retinopathy (NDR)group] (all P>0.05). The abdominal circumference, systolic blood pressure, fasting blood glucose, triglyceride,creatinine and low-density lipoprotein in NDM group were all lower than those in NDR group, and the differences were statistically significant (all P<0.05). BMI, abdominal circumference, systolic blood pressure, diastolic blood pressure, fasting blood glucose, HbA1c, total cholesterol, triglyceride, creatinine and LDL in NDM group were all lower than those in type 2 diabetic retinopathy (DR) group, and the differences were statistically significant (all P<0.05). The comparison between the NDR group and the DR group showed that the values of systolic blood pressure,diastolic blood pressure, HbA1c, total cholesterol, triglyceride and creatinine in the NDR group were all lower than those in the DR group, and the differences were statistically significant (all P<0.05). Conclusion: SBP ≥150 mmHg,DBP ≥90 mmHg, HbA1c ≥9%, serum creatinine ≥100 μmol/L, triglyceride ≥3 mmol/L are the high-risk factors of diabetic retinopathy.
目的:探究球面塑形镜、环曲面塑形镜在矫治近视复合散光的有效性及安全性。方法:回顾分析宜昌市第一人民医院2016年3月至2018年3月角膜塑形镜治疗青少年近视94例(178眼),按佩戴塑形镜类型分为球面塑形镜组(48例,90眼)与环曲面塑形镜组(46例,88眼)。记录配镜前、佩戴1年后、停戴1周后的视力、角膜散光、眼轴长、球镜屈光度、眼压、泪膜破裂时间及角膜着染率。结果:戴镜1年后,2组组内相比,散光、球镜度数、眼压、泪膜破裂时间均降低,但2组组间相比,仅散光度数差异有统计学意义(P<0.01)。戴镜1年后,两组视力较戴镜前显著提高,停戴后近视度数较佩戴前增加,但组间差异无统计学意义(P>0.05);2种塑形镜角膜着染发生率差异无统计学意义(P>0.05)。结论:2种塑形镜均能够降低近视复合散光患者度数,有效提高患者视力,但并不能完全阻止近视的进展。虽然环曲面塑形镜在矫正散光方面有优势,但总有效性与安全性并不占优势。
Objective: To observe the effectiveness and safety of orthokeratology lens and toric design othokeratology treatment for compound myopic astigmatism. Methods: From March 2016 to March 2018, 94 teenagers(178 eyes) were selected as the subjects of study. They were divided into two groups according to the type of orthokeratology: the orthokeratology lens group (48 cases, 90 eyes) and the toric design othokeratology group(46 cases, 88 eyes). Visual acuity, corneal astigmatism, axial length, spherical lens refraction, intraocular pressure,tear film rupture time and corneal staining rate were recorded before, after 1 year and after 1 week. Results: After 1 year of wearing the lens, astigmatism, spherical lens degree, intraocular pressure and tear film rupture time were all decreased in the 2 groups compared with each other, but only astigmatism degree was statistically significant between the 2 groups compared with each other (P<0.01). After wearing the glasses for 1 year, the visual acuity of the two groups was significantly improved compared with that before wearing the glasses, and the myopia degree was increased after stopping wearing the glasses compared with that before wearing the glasses, but the difference between the two groups was not statistically significant (P>0.05). There was no statistical significance in the incidence of corneal staining between the two types of shaping lenses (P>0.05). Conclusion: Both of the two shaping lenses can reduce the degree of myopic patients with complex astigmatism and effectively improve the visual acuity of patients, but they can not completely prevent the progress of myopia. Although toroidal shaping mirror has advantages in correcting astigmatism, its overall effectiveness and safety are not.
目的:评估硅油填充术后眼压对角膜内皮细胞的影响及变化特点。方法:选取2019年1月1日至9月30日在佛山市第二人民医院眼科中心行玻璃体切除联合硅油注射的患者共131名,分为高眼压组(n=80)和正常眼压组(n=51)。高眼压组术后任意一次测眼压>21 mmHg,正常眼压组术后眼压均≤21 mmHg。比较填充硅油前与取硅油时的角膜内皮细胞参数测量值。结果:高眼压组的平均眼压为20.79 mmHg,正常眼压组的平均眼压为14.70 mmHg(P<0.001)。取硅油时,两组角膜内皮细胞密度(corneal endothelial cell density,ECD)均明显减少,平均内皮细胞面积均明显增大(P<0.05),高眼压组内皮细胞大小变异系数(coefficient of variation of endothelial cell size,CV)明显变大(P<0.05)。高眼压组ECD丢失率(6.3%)高于正常眼压组(3.5%);其中,高眼压组中术后1~6周内的眼压升高(7.1%)、眼压≥40 mmHg(7.3%)对角膜内皮细胞影响最大。ECD丢失与眼压变化有显著相关性(r=0.176,P=0.044)。结论:硅油填充后高眼压是角膜内皮细胞丢失的重要危险因素。
Objective: To evaluate the effect of intraocular pressure (IOP) on corneal endothelial cells after silicone oil tamponade. Methods: Patients (n=131) received vitrectomy with silicone oil injection in Ophthalmology Center in Second People’s Hospital of Foshan City from January 1st to September 30th 2019 were divided into the high IOP group (n=80) and normal IOP group (n=51). IOP was >21 mmHg at any time in the high IOP group and was ≤21mmHg in the normal IOP group after surgery. The values of corneal endothelial cells before filling with silicone oil and before removing silicone oil were compared.Results: The average IOP was 20.79 mmHg in the high IOP group, and 14.70 mmHg in the normal IOP group (P<0.001). The number of endothelial cells (ECD) was reduced, but the average endothelial cell area was increased (P<0.05) in both groups. The coefficient of variation of endothelial cell size in high IOP group was increased (P<0.05). ECD loss rate was 6.3% in the high IOP group and 3.5% in normal IOP group. Increased IOP within 1–6 weeks after surgery (7.1%) and IOP ≥40 mmHg (7.3%) had the greatest impact on ECD. ECD loss was correlated with IOP (r=0.176, P=0.044). Conclusion: High intraocular pressure after silicone oil filling is an important risk factor for the loss of corneal endothelial cells.Keywords intraocular pressure; corneal endothelium; silicone oil; vitrect

青光眼是全世界范围内不容忽视的致盲性眼病,其起病隐匿,视功能损害进展迅速,晚期预后不理想。长期发展且未行治疗的青光眼患者视神经呈进行性损害,引起视力急剧下降、视野不可逆性缺损,严重降低患者的生活质量。为了适应逐渐恶化的视功能,患者注视行为发生明显变化,由此在日常活动中引起步态行为随之改变,意外事故频繁发生。故目前对于青光眼的研究引起国内外广泛重视,虚拟现实技术(virtual reality,VR)作为青光眼早期诊断及康复治疗的新手段已被现代医学所尝试。本文具体阐述了青光眼的视觉损害与注视行为及运动行为间的联系,并总结了目前国内外关于VR诊断青光眼及作为康复治疗的相关研究。
Glaucoma is a blinding eye disease that cannot be ignored worldwide. Its onset is insidious, visual impairment is progressing rapidly, and the late prognosis is not ideal. Long-term untreated glaucoma patients show progressive damage to the optic nerve, causing a sharp decline in vision, irreversible visual field defects, and severely reducing the quality of life of the patients. In order to adapt to the gradual deterioration of visual function, the patient’s gaze behavior changes significantly, which causes the gait behavior to change in daily activities, and accidents occur frequently. Therefore, the current research on glaucoma has attracted wide attention in the nation and abroad,and virtual reality (VR) technology has been tried in modern medicine as a new method for early diagnosis and rehabilitation of glaucoma. This article specifically elaborates the relationship between the visual impairment of glaucoma and the gaze behavior and movement behavior, and summarizes the current domestic and foreign research on the diagnosis of glaucoma and the rehabilitation of VR technology.

Objective: To assess the correlation between the Esterman binocular visual field (EBVF) and the visual function quality of life (VFQ) in primary chronic glaucoma patients. Methods: It is a retrospective case series study.One hundred and thirty-one patients, that is to say, two hundreds and sixty-two eyes, with primary chronic glaucoma satisfying the methodological criteria were recruited for this study, who were chosen from Beijing Tongren Hospital, Capital Medical University from March 2010 to August 2010. The Humphrey Field Analyzer Model II 750i (Humphrey Instruments, Zeiss Company) was used to perform an Esterman binocular visual field test (EBVFT) and bilateral monocular full-threshold central visual field testing using the 24-2 SITA Standard program. Visual acuities were examined by logarithm of the minimum angle of resolution (logMAR) scale. Intraocular pressure and cup-disc ratio were also recorded. The history with glaucoma and anti-glaucoma drugs, and the state of the cornea and crystalline lens were also remarked. All interviews were administered face to face by the same experienced interviewer, by using the 25-Item National Eye Institute Visual Function Questionnaire (VFQ-25). Agreement between the scores from these tests and the VFQ-25 was evaluated. Results: A total of 131 patients were recruited. In the statistics of the quality of life, seven domain scores of the VFQ-25 (self-assessment vision, color vision, near action, distant action, social function, mental health and peripheral vision) were better than the others, which meant the ability of completing the seven domain was higher. Substantial agreement was found between the composite score of the VFQ-25 and the Esterman test (r=0.24998, P=0.004<0.05), strong negative correlation was found between the composite score of the VFQ-25 and the binocular visual acuity of daily life (r=?0.37778, P<0.0001), and positive correlation was found between the composite score of the VFQ-25 and the MD of the worse eye (r=0.22917, P=0.0187<0.05).Conclusion: In this sample of clinic-based patients with primary chronic glaucoma, the efficiency score of the binocular visual field tests correlated well with the composite score of the VFQ-25. Binocular visual function can be well used in evaluating the quality of life of the glaucoma patients.

Objective: To investigate the association between lateral decubitus position (LDP) and asymmetric loss in normal tension glaucoma (NTG) patients. Methods: NTG patients were enrolled from Wenzhou Glaucoma Progression Study (WGPS) in Jan. 2014 to Sep. 2018. The main eye examinations included visual field test and optical coherence tomography (OCT). A questionnaire to determine the preferred sleeping position was administered to each patient in the baseline. According to the LDP, the eye parameters were divided into non-dependent eyes(higher lateral eyes) and dependent eyes (lower lateral position eyes) for discussion. According to the asymmetric damage, the ocular parameters of the patients were divided into the better eyes and the worse eyes for analysis.Asymmetric loss was defined as a difference in mean deviation (MD) between the 2 eyes of at least 6 dB or disc/cup >0.2. Results: One hundred and twenty-two patients (77.22%) had sleep preferences among the 158 NTG patients who was finally recruited and the longest follow up time was 48 months. Among the patients with sleep preference, 83 patients (68.03%) preferred the lateral decubitus position. Patients who had the lateral decubitus position mostly preferred the right lateral position [59 (71.1%) vs 24 (28.9%), P<0.001]. For patients who had the lateral decubitus position, the ocular parameters between the dependent eyes and the non-dependent eyes had no statistical difference(P>0.05); the rate of visual field progression in the dependent eyes was slower than that in non-dependent eyes, but there was no statistical difference between the two groups (0.48%±1.66%/year vs ?0.45%±3.07%/year; 0.54±0.96 dB/year vs 0.2±1.15 dB/year; P=0.086, P=0.308, respectively). For patients who had the lateral decubitus position and asymmetric damage, the ocular parameters between the dependent eyes and the non-dependent eyes had also no statistical difference (P>0.05); the number and ratio of the dependent-better eye and the dependent-worse eye were 48 and 41, respectively [23 (57.5%) vs 17 (42.5%), P=0.132]; the rate of visual field progression in the dependent eyes was also lower than that in non-dependent eyes, but there was no statistical difference between the two groups (1.19%±1.65%/year vs ?0.86%±3.65%/year; 0.71±1.13 dB/year vs 0.13 dB/year; P=0.064, P=0.419 respectively). Conclusion: About 68% of NTG patients with sleep preferences preferred the lateral decubitus position; and about 70% of patients with the lateral decubitus position preferred the right side sleeping. However, this study did not find a correlation between lateral decubitus position and asymmetric visual field loss.

Objective: This study used Doppler imaging and contrast-enhanced ultrasound to measure ocular haemodynamic of patients with primary angle-closure glaucoma (PACG) and primary open-angle glaucoma (POAG), to investigate the association between the blood flow changes and glaucoma. Methods: Doppler imaging and contrast-enhanced ultrasound were performed on 16 PACG patients (20 eyes, PACG group), 8 POAG patients(10 eyes, POAG group) who were diagnosed in the Department of Ophthalmology, the Second Affiliated Hospital of Harbin Medical University from Dec. 2012 to Mar. 2014. The normal eyes from 10 persons were selected as control group. The flow velocity of ophthalmic artery, central retinal artery, and posterior ciliary artery were observed, including the peak systolic velocity, diastolic peak velocity, resistance index, and the arrival time and departure time of the ultrasound microbubbles (SonoVue). Results: Compared to control group, the arrival timeof the ultrasound microbubbles (SonoVue) of ophthalmic artery of patients with POAG increased (P=0.035),and the departure time of ophthalmic artery of patients with PACG and POAG increased (P=0.010). Both peak systolic velocity and diastolic peak velocity of the ophthalmic artery and short posterior ciliary artery of patients with PACG and POAG and the central retinal artery of patients with POAG decreased (P=0.003). Meanwhile, the resistance index of ophthalmic artery of patients with PACG and POAG and the central retinal artery of patients with POAG were higher than those in the control group (P<0.001). Conclusion: The flow velocity of ocular vascular was worse than that of normal group respectively. This study provides a new technology for the diagnosis of glaucoma and the evaluation of the flow velocity of ocular vascular.
