Objective: To evaluate the clinical safety and curative effect of phacoemulsification (Phaco) combined with multifocal intraocular lens (MIOLs) implantation in the treatment of senile cataract with 2.2 mm microincision cataract. Methods: The cataract patients who underwent phacoemulsification and intraocular lens implantation in our hospital were selected from January 1, 2018 to June 31, 2018. They were divided into two groups: group A with 31 patients (35 eyes) undergoing 2.2 mm micro-incision Phaco combined with MIOLs, while group B with 31 patients (38 eyes) undergoing 3.0 mm standard incision Phaco combined with single focus IOLs.The preoperative and postoperative uncorrected visual acuity, corneal curvature, intraocular pressure, corneal endothelium number, and defocus curve were recorded in both groups. The parameters during the operation were also recorded and compared. Results: There was no statistically significant difference in the parameters including total phacoemulsification time, total phacoemulsification energy, phacoemulsification cumulative energy compound parameters, effective phacoemulsification time, average phacoemulsification energy, total surgery time between group A and group B during the operation (all P>0.05). Compared with preoperative, the number of corneal endothelial cells decreased both in the two groups after surgery. The difference was statistically significant (P<0.05). There was no significant difference between the two groups at any time (all P>0.05). There were no complications such as posterior capsule rupture during operation in both groups. The corneal astigmatism was increased after operation both in the 2.2 mm incision and 3.0 mm incision, and the difference was statistically significant compared with pre-operation (both P<0.01). There was no significant difference between the two groups (all P>0.05). At 3 months postoperatively, there was no significant difference in uncorrected distance visual acuity (UCDVA) between the two groups (t=?1.794, P=0.07), and the difference was statistically significant in the uncorrected near visual acuity (UCNVA) (t=?25.147, P<0.01). Defocus curve: The defocus curve of group A had two peaks, which are located near 0 D and ?3.5 D, forming a flat platform with a descent between the two peaks.The defocus curve of group B had only one peak, located at 0–0.5 D, and the downward trend at both ends of the peak was obvious. The rate of off-glasses and satisfaction: the rate of off-glasses in group A was 77.42% (24/31),and the rate of dislocation in group B was 12.90% (4/31). The difference was statistically significant (χ2 =26.050,P<0.01). There was no significant difference in overall satisfaction between the two groups (χ2 =1.615, P=0.204).Conclusion: The 2.2 mm coaxial microincision cataract surgery yields high clinical safety, and the combined implantation of multi-focal intraocular lens has good curative effect and can be widely promoted in clinical practice.
近年来日益强大的眼内液分子/细胞生物学检测技术因其简便、快捷和高效的特点,使得眼科医生在诊断眼内淋巴瘤时倾向于单纯只依据此类方法而淡化病理诊断的重要性。眼内液分子/细胞生物学技术因其本身只能“间接提示肿瘤细胞存在”的局限性而不能作为眼内淋巴瘤的确诊依据。眼内组织/细胞病理仍然是眼内淋巴瘤诊断的金标准,其价值和地位不能被其他任何分子/细胞生物学检测手段所替代。理解并掌握各种诊断、检测技术的优势和局限性,规范和优化眼内组织/细胞病理标本的采集、保存和送检流程有助于提高眼科临床医生对眼内淋巴瘤的诊断效率和医疗质量。
In recent years, more and more powerful molecular/cellular biological techniques of intraocular fluid have made ophthalmologists tend to only rely on these methods in the diagnosis of intraocular lymphoma because of their features of simplicity, fastness and efficiency. The molecular/cellular biological techniques of intraocular fluid cannot be used as the basis for the diagnosis of intraocular lymphoma because it can only indicate the existence of tumor cells indirectly. Intraocular tissue/cell pathology remains the gold standard for the diagnosis of intraocular lymphoma, and its importance cannot be replaced by any other molecular/cell biological methods. Understanding and mastering the advantages and limitations of various diagnostic techniques, standardizing and optimizing the collection, preservation and submission process of intraocular tissue/cell specimens will help ophthalmologists improve the diagnostic efficiency and medical quality of intraocular lymphoma.
眼内淋巴瘤(intraocular lymphoma,IOL)比较罕见。按起源位置分为两种类型,主要类型为原发性眼内淋巴瘤(primary intraocular lymphoma,PIOL),也称为原发性中枢神经系统淋巴瘤(primary central nervous system lymphoma,PCNSL);另外一种类型为继发性眼内淋巴瘤(secondary intraocular lymphoma,SIOL),为中枢神经系统以外的淋巴瘤转移至眼内。按肿瘤类型主要分为三类,主要类型为眼内弥漫大B细胞淋巴瘤,属于高级别淋巴瘤,预后较差;其次为少见的主要侵犯脉络膜的黏膜相关淋巴组织结外边缘区B细胞淋巴瘤,属于低级别淋巴瘤,预后较好;第三种类型为极少见的眼内NK/T细胞淋巴瘤,属于高级别淋巴瘤,预后极差。该病的诊断对眼科医生和病理医生都极具挑战性。实验室检测方法主要包括病理学、免疫细胞化学、流式细胞术、细胞因子及基因重排等,但眼内病理活检仍然是该病诊断的金标准。该病的治疗主要为眼内局部化疗、放射治疗及系统性化疗。IOL早期常因误诊而耽误治疗,目前该病明确诊断时多在患者出现症状后4~40个月,多数病例早期被误诊为葡萄膜炎而失去治疗的最佳时机,导致预后较差。因此应充分认识IOL的早期表现,早期诊断、早期治疗,从而大大提高疗效。
Intraocular lymphomas (IOL) are rare malignant neoplasms including primary intraocular lymphoma (PIOL) and secondary intraocular lymphoma (SIOL). The former is also known as primary central nervous system lymphoma(PCNSL). The latter is a kind of lymphoma metastasizing to the eye from outside the central nervous system. IOL can further be divided into three different types. The most common type is vitreoretinal high-grade diffuse large B-cell lymphoma with poor prognosis. The less common type is primary choroidal extranodal marginal zone B-cell lymphoma of mucosa associated lymphoid tissue, which is low-grade B-cell lymphoma with better prognosis.The rare type is NK/T cell lymphomas with very poor prognosis. The diagnosis of this disease is challenging for both ophthalmologists and pathologists. Laboratory testing methods mainly include cytology/pathology,immunocytochemistry, flow cytometry, cytokine analysis and gene rearrangement detection. The detection of malignant lymphoid cells cytologically/pathologically is still the gold standard for diagnosing IOL. The treatment involves local chemotherapy, radiotherapy and systemic chemotherapy. Most intraocular lymphomas at early stage are misdiagnosed as uveitis and proper treatment is often delayed with poor diagnosis due to the lost of best time for treatment. So far, the delay between the diagnosis and the onset of ocular symptoms ranges from 4 to 40 months. Therefore, we should fully understand the early manifestations of intraocular lymphoma and early diagnose and timely treat the disease in order to improve prognosis.

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
随着白内障手术由复明性向屈光性转变,对角膜的散光矫正显得越来越重要。而角膜散光不仅仅应该关注角膜前表面的散光数据,更应该考虑角膜后表面的散光,否则对散光人工晶状体植入矫正角膜散光可能出现不同程度的术后屈光误差。角膜后表面散光均值约为0.37 D,且多数情况下会产生逆规散光的效果,因此在进行散光型人工晶状体计算时应考虑到这一特点,进一步防止术后欠矫或过矫的发生。
With the cataract surgery evolving from visual restoration surgery to refractive surgery, surgical correction of corneal astigmatism becomes more and more important. For Toric intraocular lens implantation, the surgeon should not only pay attention to the values in surface of anterior corneal astigmatism but also that in posterior corneal astigmatism. Otherwise,unwanted postoperative refractive errors may occur. The mean value of posterior corneal astigmatism was around 0.37 D.In most cases, the posterior corneal astigmatism produces against-the-rule effect. Therefore, the above-mentioned feature of posterior corneal astigmatism should be noticed to prevent the under-correction or over-correction effect of toric lens.
青光眼是世界范围内致盲和引起视力损害的主要眼病,也是不可逆性致盲性眼病之一。眼压是青光眼发生发展的重要危险因素,但除眼压外,血压在青光眼进展引起的影响也不可忽视。眼灌注压是血压和眼压的差值,可调节视神经的血液供应。眼压、血压、灌注压在青光眼发生发展中有一定相关性。本文通过对眼压和血压在青光眼中的影响以及24 h眼压和血压监测在青光眼中的应用进行文献索引,分析青光眼24h眼压和血压同步监测的意义。
Glaucoma is a major eye disease causing blindness and visual damage worldwide, and it is also one of the irreversible eye diseases causing blindness. Intraocular pressure (IOP) is an important risk factor for the development of glaucoma, and the influence of blood pressure (BP) on the progression of glaucoma also cannot be ignored. Eye perfusion pressure is the difference between blood pressure and intraocular pressure, regulating the blood supply to the optic nerves. IOP, BP and perfusion pressure are related to the occurrence and the progression of glaucoma. Literature review was performed related to the effects of IOP and BP on glaucoma, and the application of 24-hour IOP and BP monitoring in glaucoma, aiming to analyze the significance of simultaneous monitoring of IOP and BP for 24 hours.
白内障作为一种常见的眼科疾病,是全球第一位致盲眼病,目前尚无药物能够治疗,手术是唯一有效的办法。随着现代眼科手术技术的发展以及人工晶状体(intraocular lens,IOL)设计和功能的更新升级,人们对视觉质量的要求越来越高,白内障超声乳化联合IOL植入术已经从单纯的复明手术转变为个性化的屈光手术。为满足不同需求的患者术后获得较好的视觉质量,IOL经历了从单焦点到多焦点、球面到非球面的发展,还有散光型IOL和各类功能性IOL的临床应用,也为患者提供了更多的选择。充分了解不同类型IOL的优势和特点,根据患者自身眼部情况、日常用眼习惯以及需求,个性化地选择IOL植入对视觉质量的恢复和满意度起着至关重要的作用。因此本文将针对不同类型的IOL,从设计与分类、术后临床效果及适应人群进行综述,为IOL的选择提供指导建议。
As a common eye disease, cataract is the first-leading cause of blindness in the world. Currently, there is no drug to treat it, and surgery is the only effective way. With the development of modern ophthalmic surgical technology and the updating and upgrading of the design and function of intraocular lens (IOL), people have higher and higher requirements for visual quality. Cataract phacoemulsification combined with IOL implantation has transformed from a simple vision restoration to personalized refractive surgery. In order to meet the needs of patients with different needs to obtain better visual quality after surgery, IOL has experienced the development from monofocal to multifocal, spherical to aspherical, as well as the clinical application of astigmatic IOL and various functional IOLs, which also provides more choices for patients. Fully understanding the advantages and characteristics of different types of IOLs, according to the patient’s own eye conditions, daily eye habits and needs, individualized selection of IOL implantation plays a crucial role in the recovery and satisfaction of visual quality. Therefore, this article will review different types of IOLs from the aspects of design and classification, postoperative clinical effects and adaptation to the population, and provide guidance for the selection of IOLs.

Objective: To analyze the clinical presentation, surgical management, and outcomes of rhegmatogenous retinal detachment (RRD) in patients with high-myopia corrected by posterior chamber phakic (PCP) intraocular lens (IOL) implantation. Methods: Nine eyes of 9 patients in whom RRD developed after PCPIOL implantation from April 2012 to June 2021 in Zhongshan Ophthalmic Center were retrospectively studied. Mean follow-up after retinal detachment surgery was (4.96±4.78)months. Results: Mean patient age was (30.44±20.11) years old. RRD occurred (32.10±17.80) months after PCPIOL implantation. Four (44.4%) breaks were horseshoe tear, 1 (11.1%) was atrophic hole and 4 participants (44.4%) had a giant retinal tear. Nine cases had causative breaks located anterior to the equator while peripheral retina lattice degeneration was found in 6 eyes. RRD extended from 1 to 4 quadrants (3.0±1.12 quadrants) and 8 cases were macula-off retinal detachments. Four eyes’ proliferative vitreoretinopathy were more severe than level C. Initial reattachment rate was 77.80%. Final retinal reattachment was 100%. Final follow-up BCVA was significantly better than baseline (P<0.05). Furthermore, concurrent cataract occurred in 2 eyes in which silicone oil was used as tamponade. Ocular hypertension was detected in 4 eyes after surgery. Conclusion: The existed lattice degeneration and postoperative vitreous traction may be risk factors for RRD after PCPIOL implantation.

Objective: To compare the effects of different types of non-depolarizing muscle relaxants including rocuronium,cis-atracurium and mivacurium on intraocular pressure of glaucoma patients with elevated intraocular pressure during induction of general anesthesia. Methods: Glaucoma patients with intraocular pressure >21 mmHg were randomly assigned to rocuronium group, cis-atracurium group and mivacurium group. After target controlled infusion of propofol until the bispectral index (BIS) lower than 55, 0.6 mg/kg rocuronium, 0.1 mg/kg cisatracurium and 0.2 mg/kg mivacurium were injected intravenously according to different groups. The flexible laryngeal mask was placed after the train-of-four stimulation (TOF) ratio decreased to 0 and the mechanical ventilation was implemented immediately. General anesthesia was maintained by 1.5–2.0 μg/kg fentanyl and 2%– 3% sevoflurane. Intraocular pressure and hemodynamic parameters were measured before anesthesia induction (T0), after sedation (T1), after muscle relaxation (T2), and after laryngeal mask insertion (T3). Results: The intraocular pressure of patients in rocuronium group, cis-atracurium group and mivacurium group at T1, T2, T3 were lower than baseline (T0), and the difference was statistically significant (P<0.001); There was no significant difference in intraocular pressure at T2 compared with T1 in rocuronium group, cis-atracurium group and mivacurium group (P=0.337, P=0.520 and P=0.062 respectively); The difference of intraocular pressure between T2 and T1 in rocuronium group, cis-atracurium group and mivacurium group were (0.68±4.39), (0.36±3.72) and (1.27±3.91) mmHg respectively and there was no significant difference among the groups (P=0.353). Conclusion: The non-depolarizing muscle relaxants rocuronium, cis-atracurium and mivacurium have no significant effect on the intraocular pressure of glaucoma patients with elevated intraocular pressure, and there is no significant difference among the three muscle relaxants.
