目的:探讨光学相干断层扫描血管成像(optical coherence tomography angiography,OCTA)在糖尿病性视网膜病变中的应用。方法:选取2021年中山大学附属第七医院眼科63例糖尿病患者为研究对象,分为无糖尿病性视网膜病变(T0,21眼)、轻度非增殖期(T1,21眼)、中重度非增殖期(T2,14眼)及增殖期(T3,7眼)。收集各组生化指标,包括空腹血糖、糖化血红蛋白、谷丙转氨酶、谷草转氨酶、碱性磷酸酶、血清尿素氮、肌酐、尿素氮肌酐比值,及OCTA数据,即中心视网膜厚度、Angiography3×3及Angiography6×6血管线性密度及血管灌注密度等。采用单因素方差分析比较各组间差异。结果:T2组、T3组与T0组相比,T3组与T1组相比,糖尿病病程延长;T3组与其他各组相比,尿素氮升高;T1组、T2组、T3组与T0组相比,T3组与T1组相比,6 mm ×6 mm外层血流线性密度减少;与T0组相比,T1组、T2组及T3组6 mm ×6 mm完整血流线性密度减少;与T0相比,T2组、T3组6 mm ×6 mm外层血流灌注密度减少;与T0组相比,T3组6 mm ×6 mm完整血流灌注密度减少;T2组、T3组与T0组相比,T3与T1相比,3 mm ×3 mm内层血流线性密度明显减少;T3组与T0组及T1组相比,3 mm ×3 mm完整血流线性密度减少。结论:随着糖尿病性视网膜病变的进展,患者的尿素氮及肌酐逐渐升高,OCTA的血流线性密度及血流灌注密度逐渐减少。与血流灌注密度相比,血流线性密度对于早期糖尿病性视网膜病变筛查可能更为敏感。而利用Angiography6×6模式可能可以更早地发现糖尿病性视网膜病变的视网膜血流变化。
Objective: To explore the applications of optical coherence tomography angiography (OCTA) in diabetic retinopathy. Methods: A total of 63 diabetic patients in the Department of Ophthalmology, Seventh Affiliated Hospital of Sun Yat-sen University in 2021 were divided into 4 groups: the patients without diabetic retinopathy (T0, n=21), mild non-proliferative diabetic retinopathy (T1, n=21), moderate-to-severe non-proliferative diabetic retinopathy (T2, n=14) and proliferative diabetic retinopathy (T3, n=7). Biochemical Indicators were collected in all patients, such as fasting plasma glucose (FPG), glycated hemoglobin A1c (HbA1c), alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), the blood urea nitrogen (BUN), creatinine (CRE) and the ratio of blood urea nitrogen and creatinine (BUN/CRE). The Macular Cube 521×128, Angiography3×3, and Angiography6×6 models of OCTA were used to obtain central retinal thickness (CRT), vascular density (VD) and perfusion density (PD) of each group. The data of all subjects was applied to do one-way ANOVA. Results: Prolonged duration of diabetes in T2 and T3 compared to T0 and in T3 compared to T1. Elevated BUN in T3 compared to all other groups. When T1, T2 and T3 were compared to T0, and T3 was compared to T1, the VD of the 6 mm ×6 mm outer layer decreased. Reduced VD of intact 6 mm ×6 mm region in T1, T2 and T3 compared to T0. Declining PD of the 6 mm ×6 mm outer layer in T2 and T3 compared to T0. Diminished PD of whole 6 mm ×6 mm area at T3 compared to T0. The VD of 3 mm ×3 mm inner layer was significantly reduced in T3 compared to T0 and T1. The VD of 3 mm ×3 mm intact area gradually dwindled in T3 compared with T0 and T1 (P<0.05). Conclusion: With the progression of diabetic retinopathy, the levels of BUN and CRE gradually increased, and the OCTA-derived vascular density and perfusion density gradually decrease. Vascular density may be more sensitive for early diabetic retinopathy screening than perfusion density.The use of the Angiography6×6 model may result in an earlier detection of changes in retinal blood flow in diabetic retinopathy.
目的:探讨无糖尿病性视网膜病变(diabetic retinopathy,DR)的糖尿病人群中,糖尿病与近视对黄斑区节细胞-内丛状层(ganglion cell layer and inner plexiform layer,GCIPL)厚度纵向变化的影响。方法:纳入广州糖尿病眼病研究中1165名基线无视网膜病变的糖尿病和正常对照者,纵向随访2年。根据是否存在近视[等效球镜(spherical equivalent,SE)≤-3屈光度(diopter,D)]和糖尿病分为健康组(n=508)、糖尿病组(n=525)及糖尿病合并近视组(n=132)。扫频光学相干断层成像(swept source-optical coherence tomography,SS-OCT)技术测量并比较三组间GCIPL厚度的变化,以确定糖尿病和近视的影响,三组间差异使用协方差分析,采用线性混合模型分析评估GCIPL厚度与相关因素的关系。结果:对照组的SE为(1.07±1.06) D,糖尿病组为(1.02±1.00) D,糖尿病合并近视组为(-5.36±2.30) D,组间差异有统计学意义(P<0.001)。对照组基线GCIPL厚度为(71.1±0.3) μm,糖尿病组为(74.4±0.2)μm,糖尿病合并近视组为(71.7±0.5) μm。在2年随访过程中,对照组GCIPL厚度下降-0.10(95%CI:-2.03~0.05) μm/年,糖尿病组GCIPL厚度下降的速度为对照组的12倍[-1.21(95%CI:-24.04~0.05) μm/年,P<0.001],糖尿病合并近视组GCIPL厚度下降的速度为对照组的22倍[-2.17(95%CI:-21.63~0.10)μm/年,P<0.001]。结论:近视是无DR的糖尿病患者中GCIPL加速变薄的危险因素,糖尿病和近视在GCIPL损伤中可能存在协同作用。
Objective: To investigate the association between myopia and ganglion cell layer and inner plexiform layer (GCIPL) in diabetic population without diabetic retinopathy (DR). Methods: In this Guangzhou Diabetic Eye study, a total of 1 165 patients aged 30–80 years were recruited followed up longitudinally for 2 years. According to the presence or absence of myopia [spherical equivalence (SE)≤-3 diopter (D)] and diabetics, the patients were divided into a healthy group (n=508), a diabetes mellitus group (n=525), and a diabetes mellitus + myopia group (n=132). GCIPL was measured via swept-source optical coherence tomography. Univariable and multivariable mixed models were used to show the association of GCIPL change and baseline parameters. Results: SE was (1.07±1.06) D in the healthy group, (1.02±1.00) D in the diabetes mellitus group and (-5.36±2.30) D in the diabetes mellitus + myopia group (P<0.001). The baseline GCIPL thickness were (71.1±0.3), (74.4±0.2), and (71.7±0.5) μm, respectively. The slope of GCIPL thickness was -0.10 (95% CI: -2.03 to 0.05) μm/year in the healthy group, which was 12 folds faster than those in the diabetes mellitus group [-1.21(95% CI: -24.04 to 0.05 μm/year, P<0.001] and 22 folds higher among those in diabetes mellitus + myopia group [-2.17 (95% CI: -21.63 to 0.10) μm/year, P=0.009]. Conclusion: Both myopia and diabetes status accelerate macular ganglion cell layer and inner plexiform layer thinning in diabetic patients without diabetic retinopathy.

With the change of human lifestyle and overuse of eyes in recent years, the market demand for ophthalmic drugs continues to grow. However, the ocular therapy is still facing the shortage of doctors and drugs. Due to the risk of high cost, long lead time and low success rate, the process of novel ophthalmic drug innovation and iteration is getting slower. As an emerging technology, artificial intelligence is expected to enable the whole process of ophthalmic drug discovery and development, including drug target discovery, compound screening, pharmacokinetic model innovation and clinical trials, thus reducing R&D costs and increase efficiency for ophthalmic drug discovery and development. In addition, with the improvement of big data, hardware calculation and the deep integration of life science and intelligent science, the role of artificial intelligence in ophthalmic drug discovery and development will be significant improved , contributing to achieve the leap from precision to intelligence.
本文报告1例28岁男性青年患者,行飞秒制瓣准分子激光原位角膜磨镶术(laser-assisted situ keratomileusis,LASIK)术后1个月视力进行性下降,小瞳下行电脑验光矫正视力,右眼为0.3(-0.25×86°),左眼为0.2(-0.50×91°)。眼前节及眼底检查未见器质性病变,视觉电生理检查未见异常。视光专科检查示负相对调节/正相对调节(negative correlatione regulation/positive ccorrelation regulation,NRA/PRA):+2.00 D/-10.00 D(行PRA时稍作停顿后又可看清),Flipper拍检查:右眼(oculus dexter,OD) 10 cpm(+),左眼(oculus sinister,OS) 22 cpm(+),双眼(binocular,OU) 12 cpm(+),正镜片逐渐通过困难。隐斜检查:2△BO@D,13△BI@N。调节性集合与调节的比值(accommodation convergence/accommodation,AC/A)=1。患者PRA显著增高,Flipper检查正片通过困难,看近时外隐斜大于看远,提示可能存在“集合不足,调节超前”。给予托比卡胺滴眼液滴眼3次后验光:OD +1.00/-0.50×80°=1.0,OS +0.75/-0.25×65°=1.0,进一步证实了“调节痉挛”的诊断。给予托比卡胺滴眼液滴双眼,睡前1次,结合调节放松训练。4周后,裸眼视力及屈光度稳定在正常范围。临床上对于视力下降原因不明、排除眼部器质性疾病的患者,经过仔细询问病史、睫状肌麻痹检影和视功能检查“调节痉挛”不难诊断。除传统的睫状肌麻痹剂和近附加镜外,治疗方案建议加用视功能训练可使视力恢复并稳定。
A 28-year-old man was referred to our hospital because of blurred vision in both eyes after LASIK flap made by femtosecond laser surgery for 1 month. The best corrected visual acuity based on computerized optometry was 0.3 (-0.25×86°) in the right eye and 0.2 (-0.50×91°) in the left eye. Routine examinations were conducted to exclude eye diseases. Visual electrophysiological examination showed no abnormalities. Optometry specialty examination: negative relative accommodation (NRA) and positive relative accommodation (PRA) were +2.00 D/?10.00 D (when doing PRA, the patient could see clear slowly after a pause). Flipper examination showed: OD 10 cpm(+), OS 22 cpm(+), OU 12 cpm(+). Phoria-measurement showed 2 prism degree BO@D and 13 prism degree BI@N. AC/A=1. The patient’s high PRA, flipper examination results and convergence insufficiency at near distance indicated the possibility of “convergence insufficiency and accommodative spasm”. Cycloplegic refraction was planned to assess the real diopter. After instillation of cycloplegic drops, the UCVA improved to 1.0 and the refractive error to -0.25×93 in the right eye, in the left eye to 1.0 and the refractive error to -0.25×75. the BCVA was 1.0 (+1.00/-0.50×80°) in the right eye and 1.0 (+0.75/-0.25×65°) in the left eye. A diagnosis of accommodative spasm was made. The patient was counseled and continued cycloplegic drops one time daily before bedtime, participated in vision training for 4 weeks. This patient was a rare occurrence of accommodative spasm after FSLASIK surgery. Young patients with poor gain in UCVA can be subjected to a corrective procedure accidentally. Relaxation exercises and cycloplegic drops may cure accommodative spasm. For patients with unexplained causes of vision loss and excluded organic diseases of the eye, it is not difficult to diagnose “accommodative spasm” by careful medical history inquiry, ciliary muscle paralysis optometry and visual function examination. In addition to traditional ciliary palsy agent and reading glasses, it is suggested that visual function training can restore and stabilize the treatment effect.
目前对于成人圆锥角膜(keratoconus,KC)的研究已经很广泛,而对于儿童KC的研究则较少,其诊断和治疗常常基于成人KC的研究基础。与成人KC相比,儿童KC的发展更迅速、造成的后果更严重,其导致的儿童视觉障碍会追随其一生,对其生活质量以及教育发展产生严重的负面影响。为了对儿童KC的治疗有较全面的认识和理解,本文针对近几年儿童KC的治疗进展,对不同治疗方法的安全性、有效性和治疗时机等方面进行综述。
At present, the research on adult keratoconus has been extensive, while the research on pediatric keratoconus is few. The diagnosis and treatment of pediatric keratoconus are often based on the study of keratoconus in adults. Pediatric keratoconus is more aggressive than adult keratoconus, resulting in visual impairment that can follow throughout their lives and have a serious negative impact on their quality of life and educational development. In this paper, according to the treatment progress of pediatric keratoconus in recent years, the safety, effectiveness, and treatment timing of different treatment methods were summarized, in order to have a more comprehensive understanding of the treatment of pediatric keratoconus.

Objective: To conduct a preliminary study of the Lea Symbols and HOTV charts to explore the visual development of children aged 2.5 to 5.0 years, and evaluate the application values of the two charts. Methods: A total of 461 children (922 eyes) in 2 early education centers and 3 kindergartens in Guangzhou were examined by using the Lea Symbols visual acuity chart and HOTV visual acuity chart in random order. All the children underwent low-pupil photometry, anterior section slit-lamp examination, retinal condition, eye movement, and eye position examination 1 day in advance. Children with no organic eye disease and normal diopter were selected as subjects. Visual acuity was recorded with 5 points. Results: 1) Measurable rate (visual acuity chart use degree of cooperation). 407 children completed visual examination of Lea Symbols, with an overall detectable rate of 92.08%; 402 children completed HOTV vision examination, with an overall detectable rate of 90.95%. The detectable rate of the former was higher than that of the latter, but the difference was not statistically significant (χ2=0.417, P=0.580). Further study found that the detectable rate of both visual acuities increased with age, and children were able to complete both visual acuity tests after the age of 3. 2) Results and comparison of two visual acuity (5-point recording method). The visual acuity of Lea was 4.89±0.05 in the right eye and 4.90±0.05 in the left eye. HOTV visual acuity was 4.84±0.05 in the right eye and 4.85±0.04 in the left eye. The visual acuity of the former was better than that of the latter, the difference was statistically significant (right eye: t=3.171, P=0.003; left eye: t=3.230, P=0.003). 3) Correlation between visual development and age. There was a significant positive correlation between the two types of visual development and age (P<0.001), that is, visual acuity gradually improves with age. 4) The relationship between visual development and eye and sex. There was no difference in visual development between the left and right eyes, but male children had better visual development than female, and the difference was statistically significant (P<0.05). Conclusion: Lea Symbols and HOTV visual acuity charts are recommended for visual acuity examination of children over 3 years old, and children are more likely to receive examination of Lea Symbols visual acuity chart. With the growth of age, the visual development of children shows a trend of improvement. Lea vision is superior to HOTV vision. Vision development has nothing to do with the eye, male children’s vision development is faster than female children.
目的:探究特发性黄斑前膜(idiopathic macular epiretinal membrane,IMEM)患者在光学相干断层扫描(optical coherence tomography,OCT)的形态学改变与视力的相关性。方法:回顾性研究。基于OCT图像4级分级方案,纳入3级及以下的特发性黄斑前膜患者35例共37只眼进行OCT扫描,并借助第三方软件分析并获取每只眼在黄斑中心凹直径分别为1、3、6 mm共3个同心圆区域内视网膜各层的平均厚度值,并按照是否存在内核层(inner nuclear layer,INL)囊样改变分为两组。通过建立最小分辨角对数(minimum resolution angle in logarithmic,logMAR)最佳矫正视力(best corrected vision acuity,BCVA)与视网膜各层厚度值的多元线性回归方程,以及比较有INL囊样改变及无INL囊样改变两组的视力,分析视力与视网膜各层厚度值及INL囊样改变的关系。结果:多元线性回归分析显示,在直径1 mm的区域内,logMAR BCVA与神经纤维层(retina nerve fiber layer,RNFL)、INL的厚度值均呈正相关(均P<0.05),而在直径3 mm和6 mm的区域内,logMAR BCVA仅与INL的厚度值呈正相关(均P<0.05)。与无INL囊样改变组相比,有INL囊样改变组视力及INL厚度差异均有统计学意义(均P<0.05)。结论:特发性黄斑前膜患者当前的视力主要与RNFL和INL厚度值相关。发生在INL层的囊样改变可能很好的提示INL增厚,其与视力具有相关性,具有这种囊样改变的患者往往视力也较差。
Objective: To investigate the morphological changes detected by spectral domain optical coherence tomography (OCT) and their relevance to vision in patients with idiopathic macular epiretinal membranes (IMEM). Methods: This is a retrospective study. OCT recorded 37 eyes with stage 3 and below IMEM according to the 4-level grading system based on OCT images among 35 patients. We managed to obtain thickness of all retina layers in three concentric circular regions with a diameter of 1 mm, 3 mm and 6 mm across macular fovea with the help of a third-party software. Plus we divided all 37 eyes into two groups according to whether there were cystic changes in the inner nuclear layer (INL). Multiple linear regression analyses were performed between thickness of all retina layers and current minimum resolution angle in logarithmic (logMAR) best corrected visual acuity (BCVA). The difference of BCVA between groups with cystic changes and without was also compared. Thus, the relationships between visual acuity and thickness of retina layers, cystic changes in INL were analyzed. Results: Multiple linear regression analyses revealed that thickness of both retina nerve fiber layer (RNFL) and inner nuclear layer have positive correlation with logMAR BCVA in the region with a diameter of 1 mm (P<0.05), while in regions of a diameter of 3 mm and 6 mm, only INL thickness remained positively relevant (all P<0.05). There were significant differences in BCVA and thickness of INL between groups with INL cystic changes and without (all P<0.05). Conclusion: Current visual acuity among preoperative IMEM patients was mostly associated with thickness of RNFL and INL. Cystic change in INL layer may be a good indicator of INL thickening and was visually correlated. Those with this change tend to have worse vision.

Objective: To investigate the effect of conductive education training on the quality of life in visually impaired students. Methods: It was a prospective randomized controlled trial. The visual impairment students who had registered in Quanzhou Special Education School in 2020 were selected and randomly divided into two groups: conductive education training group and control group. The conductive education training group received conductive education training, while the control group received routine rehabilitation training. Chinese version low vision quality of life questionnaire (CLVQOL) was used to assess the quality of life of low vision students at baseline and 3 months after training, and comparative analysis was conducted. Results: All 72 students with visual impairment completed CLVQOL surveys. At baseline, there was no significant difference in total CLVQOL scores between groups. After 3 months, overall CLVQOL scores increased in both groups, from baseline 59 (48.5, 80.5) to 105 (97.5, 119.5) in the conductive education group (Z=?4.781, P<0.001), and 69 (56, 85) to 106 (80, 112) in the control group (Z=?4.438, P<0.001). The total score of CLVQOL (P=0.021), reading and fine work subscale (P=0.004), and daily activities subscale (P<0.003) in the conductive education training group were higher than those in the control group. Conclusion: Conductive education training is an important method of low vision rehabilitation training, which can significantly improve the quality of life of patients.
