Background: Diabetic individuals provide a specific problem because to their propensity for the premature development of cataracts. The objective of this research is to examine the association among characteristics after phacoemulsification in diabetic individuals, and postoperative central corneal thickness (CCT), alterations in density of corneal endothelial cell using specular microscopy. Methods: This research was carried out on a cohort of forty individuals who had uncomplicated phacoemulsification surgery for the purpose of cataract extraction. The research design was prospective, selective non-randomized and interventional. The participants were allocated into two groups of equal size. In Group one, individuals with complex cataracts received a successful phacoemulsification procedure without any complications. Group two composed of non-diabetic individuals who received phacoemulsification for the treatment of senile cataract without any complications.Results: In both non-diabetic and diabetic individuals, the preoperative corneal thickness (CCT) exhibited a positive association with the coefficient of variation (CV) and a negative association with endothelial cell count (ECC). Diabetic subjects had a negative correlation with CCT while healthy subjects had a favorable one. One and three months after surgery, CCT was negatively correlated with ECC and HEX and positively correlated with CV in the diabetes group. The logarithm of minimum angle of resolution (log MAR) of best-corrected visual acuity (BCVA) exhibited a positive correlation with central CCT at the one-month postoperative mark, and a negative correlation at the three-month postoperative mark. In the non-diabetic group, there was a positive association observed among BCVA and CCT when expressed in log form. Conversely, a negative correlation was found among CV and CCT. The correlation among CCT and HEX was shown to be positive at the three-month stage of postoperative and negative at the first-month stage of postoperative. There was a positive correlation observed among CCT and ECC during the first-month postoperative period. However, at the three-month postoperative period, a negative correlation was found between CCT and ECC.Conclusions: There is an important variance of corneal endothelial loss after phacoemulsification between non-diabetic and diabetic population. Diabetic individuals demonstrated significantly more endothelial damage after phacoemulsification.
背景:糖尿病患者提供了一个特殊的问题,因为他们倾向于白内障的过早发展。本研究的目的是利用镜面显微镜检查糖尿病患者超声乳化术后的特征与术后角膜中央厚度(CCT)、角膜内皮细胞密度改变之间的关系。方法:本研究对40例行单纯超声乳化白内障摘除手术的患者进行队列研究。研究设计为前瞻性、选择性、非随机、干预性。参与者被分成两组,人数相等。在第一组中,患有复杂白内障的患者接受了成功的超声乳化手术,没有任何并发症。第二组为无糖尿病的老年性白内障行超声乳化术治疗,无并发症。结果:在非糖尿病和糖尿病患者中,术前角膜厚度(CCT)与变异系数(CV)呈正相关,与内皮细胞计数(ECC)负相关。糖尿病受试者与CCT呈负相关,健康受试者与CCT呈正相关。糖尿病组术后1、3个月CCT与ECC、HEX呈负相关,与CV呈正相关。最佳矫正视力(BCVA)最小分辨角(log MAR)的对数与中心CCT在术后1个月时呈正相关,在术后3个月时呈负相关。在非糖尿病组中,以对数形式表达的BCVA与CCT呈正相关。相反,CV与CCT呈负相关。CCT与HEX在术后3个月时呈正相关,术后1个月时呈负相关。术后1个月CCT与ECC呈正相关。然而,在术后3个月,CCT与ECC呈负相关。结论:非糖尿病人群和糖尿病人群超声乳化术后角膜内皮损失存在重要差异。糖尿病患者超声乳化术后内皮损伤明显加重。

Background: Phacoemulsification surgery is performed in a limited space, therefore, anatomy and procedural parameters, such as sufficient anterior chamber depth (ACD), are essential for protecting endothelial cells during surgery from mechanical and heat damage. Specular microscope is a useful non-contact investigational technique that photographs the human corneal endothelium. Methods: This a prospective comparative cohort non-randomized study included sixty eyes of phacoemulsification cataract surgery were collected from the outpatient clinics of Tanta University Hospitals and were admitted to Ophthalmology Department. Cases were divided into three groups according to ACD. All cases were subjected to: history taking, examination [visual acuity (VA), slit lamp examination, ACD measurement using IOL master

Thyroid-associated Ophthalmopathy (TAO) is an ocular condition that frequently manifests with thyroid disfunction, and is the most common extrathyroidal manifestation of Graves’ disease. It involves an organ specific autoimmune reaction that can affect the thyroid gland, orbital and periorbital tissue. The condition primarily affects women and it is the commonest cause of unilateral and bilateral axial proptosis in young and middle -aged adults. The clinical presentation may vary from mild disease to severe irreversible sight threatening complications. Here we report a case of 35-years old female who presented to our OPD with complaints of protrusion of both eye, diminution of vision in both eye, pain, redness and unable to move eye in the last 2 months. She was known case of hyperthyroidism in the last one year and on regular antihyperthyroid medication.

In corneal ulcers, amniotic membrane (AM) is utilised for supporting damaged tissues, shield and protect deficiencies from further deterioration or breakdown from external influences and encourage re-cellularization of the cornea. Anti-fibrotic, anti-inflammatory, and anti-angiogenic effects, as well as an antimicrobial impact and the encouragement of epithelial and stromal repair are some of the qualities possessed by amniotic membrane. Surgical grafting to the ocular surface, non-surgical patching with a carriage device, amniotic membrane extract eye drops (AMEED), amniotic membrane with umbilical cord blood, and amniotic membrane with placental fluid are certain uses and techniques for utilising AM in corneal ulcers and corneal epithelial deficiencies.
在角膜溃疡中,羊膜(AM)用于支持受损组织,保护缺陷免受外部影响的进一步恶化或破坏,并促进角膜的再细胞化。羊膜具有抗纤维化、抗炎和抗血管生成的作用,以及抗菌作用和促进上皮和间质修复的作用。眼表移植手术、携带装置非手术贴片、羊膜提取物滴眼液(AMEED)、脐带血羊膜和胎盘液羊膜是利用AM治疗角膜溃疡和角膜上皮缺陷的某些用途和技术。

Background:Keratoconus is a progressive, non-inflammatory corneal ectasia with central thinning. The aim of this work was to evaluate intra and post-operative complications and final visual outcome of deep anterior lamellar keratoplasty (DALK).Methods: This prospective cohort interventional study was carried out on 20 patients aged from 20 to 65 years old with superficial corneal stromal opacities based on clinical examination and AS-OCT (anterior segment optical coherence tomography), advanced keratoconus with central corneal thickness below 400 microns or the presence of scarring in the visual axis. Results: Descemet's membrane (DM) perforation was encountered in 7 eyes attempted DALK (35%). Early epithelial defect happened in 13eyes post operatively mostly due to surgical manipulation of the grafts, 2 of them (10%) continue to the 3 months post operatively. Five eyes developed DM folds, three eyes (15%) developed Urrets-Zavalia syndrome, one eye 5% developed anterior cortical cataract, four eyes (20%) had interface haze. Best corrected visual acuity (BCVA) was affected in one case and improved in all cases with 85% of eyes achieved 0.5 or more after one year postoperative. Double anterior chamber (AC) was found in five eyes (25%). two eyes were successfully managed with single air injection.one eye needed DM Endothelial Keratoplasty. The mean recipient bed thickness was 42.850±8.869 um. Average K decreased significantly postoperatively. A low myopia was encountered at 6 months postoperatively. Conclusions: DALK led to reasonable postoperative visual and refractive outcome, patient age, peripheral descemet's fold, failed pneumatic dissection has no significant impact on postoperative visual acuity. Risk of DM detachment, interface haze and double AC and hemorrhage during trephination are the main complications.
背景:圆锥角膜是一种进行性、非炎性的角膜扩张,伴有中央变薄。本研究的目的是评估深前板层角膜移植术(DALK)的术中、术后并发症和最终视力结果。方法:本前瞻性队列介入研究选取20例年龄在20 ~ 65岁,经临床检查及AS-OCT(前段光学相干断层扫描)诊断为角膜浅表性间质混浊、角膜中央厚度低于400微米或视轴存在瘢痕的晚期圆锥角膜患者。结果:7眼(35%)发生视网膜膜穿孔。13只眼术后发生早期上皮缺损,主要是由于移植物的手术操作所致,其中2只眼(10%)持续到术后3个月。DM皱襞5眼,urretts - zavalia综合征3眼(15%),前皮质性白内障1眼(5%),界面混浊4眼(20%)。最佳矫正视力(BCVA)在1例中受到影响,在所有病例中均得到改善,85%的眼睛在术后1年达到0.5或更高。双前房(AC) 5眼(25%)。单次空气注入治疗成功。1只眼需要DM内皮角膜移植术。受体床平均厚度为42.850±8.869 um。术后平均K值明显降低。术后6个月轻度近视。结论:DALK术后视力及屈光效果合理,患者年龄、周围网膜皱褶、气动剥离失败对术后视力无明显影响。钻孔术中DM脱离、界面混浊、双AC和出血是主要并发症。

The mean recipient bed thickness was 42.850±8.869 um. Average K decreased significantly postoperatively. A low myopia was encountered at 6 months postoperatively. Conclusions: DALK led to reasonable postoperative visual and refractive outcome, patient age, peripheral descemet's fold, failed pneumatic dissection has no significant impact on postoperative visual acuity. Risk of DM detachment, interface haze and double AC and hemorrhage during trephination are the main complications.","PeriodicalId":14021,"journal":{"name":"International Journal of Medical Ophthalmology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136028674","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
