Purpose: To show the visual and refractive outcomes in Asian eyes with cataract when bilaterally implanted with either a hydrophobic FineVision POD F GF or a hydrophilic FineVision POD F intraocular lens (IOL).

Methods: Forty-six patients were randomized to receive POD F GF or POD F IOLs. Visual and refractive outcomes were assessed up to 24 months post-surgery. Measurements included uncorrected-distance visual acuity, corrected-distance visual acuity (CDVA), distance-corrected intermediate visual acuity (DCIVA), distance-corrected near visual acuity (DCNVA), refraction, defocus curve, photopic and mesopic contrast sensitivity, and patient-reported outcomes.

Results: Mean spherical equivalent was close to emmetropia for both groups and stable across postoperative visits. Overall, 97.73% and 100% of eyes in the POD F GF IOL group and 95.65% and 100%, of eyes in the POD F IOL group were within ±1.00D of the target refraction at 12 and 24 months, respectively. All patients showed a CDVA of ≥20/25 at 12- and 24-months post-surgery. In both groups, 24 months post-surgery 91% of patients presented a DCIVA of ≥20/25 and 83.3% of patients had a DCNVA of ≥20/25. Defocus curve showed continuous visual acuity, being 20/32 or better in both groups over a 4.00D range between 1.00D and -3.00/-3.50D. Both groups showed good contrast sensitivity values for photopic and mesopic conditions. Overall, 86.4%, 86.4%, and 72.7% of patients implanted with the POD F GF IOL reported not wearing glasses at all for distance, intermediate, and near vision, respectively. These values were 81.8%, 86.4%, and 90.9% for patients implanted with the POD F IOL. Both groups of patients reported similar satisfaction percentages (100% very satisfied/satisfied) and would recommend the procedure (100% definitively yes/probably yes).

Conclusion: This study demonstrates good visual and refractive outcomes for both the FineVision POD F GF and the FineVision POD F IOLs when implanted in Asian eyes.

目的:观察亚洲白内障患者双侧植入疏水FineVision POD F GF或亲水性FineVision POD F人工晶状体(IOL)后的视力和屈光效果。方法:46例患者随机接受POD F GF或POD F iol治疗。术后24个月评估视力和屈光结果。测量包括未矫正距离视力、矫正距离视力(CDVA)、矫正距离中间视力(DCIVA)、矫正距离近视力(DCNVA)、屈光、离焦曲线、光和介观对比敏感度以及患者报告的结果。结果:两组患者的平均球当量接近斜视,术后随访稳定。总体而言,在12个月和24个月时,POD F GF IOL组97.73%和100%的眼距目标屈光度在±1.00D以内,POD F IOL组95.65%和100%。所有患者术后12个月和24个月的CDVA均≥20/25。两组患者术后24个月,91%的患者DCIVA≥20/25,83.3%的患者DCNVA≥20/25。离焦曲线显示视力连续,在1.00D至-3.00/-3.50D的4.00D范围内,两组视力均为20/32或更好。两组在光和介观条件下均表现出良好的对比感光度值。总体而言,86.4%、86.4%和72.7%植入POD F GF IOL的患者分别报告在远视、中视和近视时根本不戴眼镜。这些数值分别为81.8%、86.4%和90.9%。两组患者报告了相似的满意度百分比(100%非常满意/满意),并会推荐手术(100%肯定是/可能是)。结论:本研究表明FineVision POD F GF和FineVision POD F iol植入术在亚洲人眼中具有良好的视力和屈光效果。

Purpose: To describe the prevalence and characteristics of posterior segment manifestations in patients with HLA-B27-associated uveitis using wide field imaging.

Methods: Medical records of patients diagnosed with HLA-B27-associated uveitis from a tertiary uveitis clinic were reviewed. Posterior segment involvements including but not limited to peripheral vasculitis, optic disc inflammation, and macula edema documented based on medical records and various imaging modalities including wide field fluorescein angiography and optical coherence tomography, were noted. Demographic characteristics, accompanied with systemic diseases as well as duration and chronicity of uveitis, were also evaluated. Patients with significant systemic and ocular comorbidities were excluded. Statistical analyses including chi-squared tests and paired t-tests were employed.

Results: Of the 44 patients with HLA-B27 associated uveitis, 22 patients (50%) were noted to demonstrate posterior segment involvement. Disc leakage and peripheral vasculitis were the most common findings of posterior involvement. Those with anterior chamber inflammation were found to have a significantly increased risk of posterior involvement. Those with posterior involvement were also noted to have a statistically significant decreased visual acuity. No significant association was found between documented duration of disease and posterior segment involvement.

Conclusion: The prevalence of posterior segment involvement in HLA-B27 associated uveitis is higher compared to previous reports when evaluated with wide angle imaging modalities. Careful examination of the posterior segment is required in patients with HLA-B27 associated uveitis.

目的:探讨hla - b27相关性葡萄膜炎患者后段表现的流行程度和特点。方法:回顾性分析某三级葡萄膜炎门诊确诊的hla - b27相关性葡萄膜炎患者的病历。后段受累包括但不限于外周血管炎、视盘炎症和黄斑水肿,根据医疗记录和各种成像方式(包括宽视场荧光素血管造影和光学相干断层扫描)记录。人口统计学特征,伴有全身性疾病,以及葡萄膜炎的持续时间和慢性性,也进行了评估。排除有明显全身和眼部合并症的患者。统计学分析包括卡方检验和配对t检验。结果:在44例HLA-B27相关葡萄膜炎患者中,22例(50%)显示累及后段。椎间盘渗漏和周围血管炎是后路受累最常见的表现。前房炎症患者后侧受累的风险显著增加。那些后侧受累的患者也有统计学上显著的视力下降。文献记载的疾病持续时间与后段受累之间没有明显的关联。结论:HLA-B27相关性葡萄膜炎累及后段的发生率比以往报道的广角成像方式高。HLA-B27相关性葡萄膜炎患者需要仔细检查后段。

The gut-eye axis has been hypothesized to be a factor in many eye pathologies. This review examines papers from PubMed about this topic. Bacterial commensals could either be protective by regulating the immune system or prove to be damaging to the gut mucosal wall and incite an inflammatory process. The balance between the two appears to be crucial in maintaining eye health. Imbalances have been implicated in ophthalmologic conditions. The use of probiotics, dietary modifications, antibiotics, and faecal microbiota transplant in mice with pathologies such as those encountered in our practice appears to reverse disease course or at least prevent its progression. Clinical trials are currently underway to investigate their clinical significance in diseased patients.

肠眼轴被认为是许多眼病的一个因素。这篇综述检查了PubMed关于这一主题的论文。细菌共栖物可能通过调节免疫系统起到保护作用,也可能对肠道粘膜壁造成损害并引发炎症过程。两者之间的平衡似乎对保持眼睛健康至关重要。不平衡与眼科疾病有关。使用益生菌、饮食调整、抗生素和粪便微生物群移植在我们的实践中遇到的病理小鼠中似乎可以逆转疾病进程或至少防止其进展。目前正在进行临床试验,以调查其在患病患者中的临床意义。

Purpose: Larger surface area glaucoma drainage implant plates are associated with greater IOP reduction. Older age and short axial length of the eye have been reported to be risk factors for postoperative hypotony and suprachoroidal hemorrhage after glaucoma surgery. This pilot study, the first of its type, was conducted to determine the clinical outcome of intraoperative Baerveldt implant plate size reduction in elderly patients (≥80 years) with short axial length (<22 mm).

Methods: This was a retrospective study with a minimum 18-month follow-up involving 24 consecutive uncontrolled glaucoma patients who had previously undergone Baerveldt implantation with implant plate size reduction. Success was defined as intraocular pressure (IOP) < 21 mmHg with at least a 30% reduction in IOP from baseline on two consecutive follow-up visits, IOP > 5 mm Hg on two consecutive follow-up visits, and neither reoperation of glaucoma nor loss of light perception. The distance between the rectus muscles at the equator of the eyeball was measured using a surgical caliper. The Baerveldt implant plate was cut with straight dissecting scissors considering the distance between the muscles.

Results: The mean ±SD preoperative IOP before GDI was 30.2 ± 6.9 mmHg, and the mean IOP at the last follow-up visit was 13.3 ± 5.1 mmHg, the mean pressure drop being 16.9 mmHg (56%) (P<0.001). The number of antiglaucoma medications declined from mean 3.7 ± 1.0 (range 2-5) to 1.6 ± 1.1 (range 0-3) at the last visit (P<0.001). The success rate at the last follow-up visit was 79% (19 of 24 eyes). Fourteen (58%) eyes were classified as qualified success and five eyes (21%) were complete success. Complications included intraoperative suprachoroidal hemorrhage (1) and postoperative hyphema (2).

Conclusion: Baerveldt implantation with customized plate downsizing can be an effective treatment option for difficult glaucoma in elderly people with short eyes.

目的:更大表面积的青光眼引流植入钢板与更大的IOP降低相关。据报道,年龄较大和眼轴长度较短是青光眼术后低眼压和脉络膜上出血的危险因素。这是该类型的首个试点研究,旨在确定短眼轴长的老年患者(≥80岁)术中Baerveldt植入钢板缩小的临床结果(方法:这是一项回顾性研究,随访至少18个月,涉及24例连续接受Baerveldt植入并植入钢板缩小的不受控制的青光眼患者。成功的定义是眼压(IOP) < 21 mmHg,连续两次随访时IOP较基线至少降低30%,连续两次随访时IOP > 5 mmHg,没有青光眼再手术或光感知丧失。用手术卡尺测量眼球赤道处直肌之间的距离。考虑到肌肉之间的距离,用直解剖剪刀切开Baerveldt植入板。结果:GDI术前平均±SD眼压为30.2±6.9 mmHg,末次随访平均眼压为13.3±5.1 mmHg,平均眼压降为16.9 mmHg (56%) (ppp)。结论:Baerveldt植入术配合定制减径钢板是治疗老年短眼难治性青光眼的有效选择。

Purpose: To determine the refractive stability of a new hydrophobic acrylic intraocular lens (IOL) when implanted bilaterally.

Methods: This was a prospective, evaluator masked, single surgeon study of 58 eyes of 29 patients. Patients were bilaterally implanted with the Clareon monofocal IOL (CNA0T0, Alcon Vision LLC). Refractive stability was evaluated between 1 and 3 months postoperatively. At 3 months postoperatively, data were also collected for binocular uncorrected and distance corrected visual acuities at distance (4 m) and intermediate (80 cm and 66 cm) and binocular defocus curve.

Results: Postoperative refraction was statistically equivalent between 1 and 3 months postoperatively (p < 0.001). Mean postoperative uncorrected distance visual acuity was -0.01 ± 0.10 logMAR, and mean corrected distance visual acuity was -0.04 ± 0.06 logMAR. Mean postoperative uncorrected intermediate visual acuity was 0.16 ± 0.13 logMAR and 0.24 ± 0.14 logMAR at 80 cm and 66 cm, respectively. With distance correction in place, mean visual acuity at 80cm and 60cm was 0.16 ± 0.13 logMAR and 0.23 ± 0.14 logMAR, respectively.

Conclusion: The Clareon monofocal IOL can provide stable refraction, excellent distance vision, and functional intermediate vision postoperatively.

目的:观察双侧植入新型疏水丙烯酸人工晶状体的屈光稳定性。方法:这是一项前瞻性、评估者蒙面、单外科医生研究,涉及29例患者58只眼。患者双侧植入Clareon单焦点人工晶状体(CNA0T0, Alcon Vision LLC)。术后1 - 3个月评估屈光稳定性。术后3个月,收集双眼未矫正视力和距离矫正视力(4 m)、中间(80 cm和66 cm)和双眼离焦曲线的数据。结果:术后1 ~ 3个月屈光度差异有统计学意义(p < 0.001)。术后未矫正距离平均视力为-0.01±0.10 logMAR,矫正距离平均视力为-0.04±0.06 logMAR。在80 cm和66 cm处,术后未矫正的平均中间视力分别为0.16±0.13 logMAR和0.24±0.14 logMAR。距离校正到位后,80cm和60cm处的平均视力分别为0.16±0.13 logMAR和0.23±0.14 logMAR。结论:Clareon单焦点人工晶状体术后屈光稳定,远视力良好,中间视力功能良好。

Purpose: To develop a clinical risk score for the prediction of urgency in patients with carotid cavernous sinus fistulas (CCFs) and test for the discriminative ability of the diagnostic prediction.

Methods: The medical charts of 60 patients with CCFs were retrospectively reviewed. The clinical characteristics of direct and dural CCFs were analyzed by logistic regression. The clinical risk score was developed from the coefficient in the multivariable regression model and used to predict direct CCFs which were more urgent than the dural type. The score prediction was reported as an area under the receiver operating characteristic (AuROC) curve and 95% confidence interval (95% CI).

Results: In a univariable analysis, the clinical characteristics which increased the risk of direct CCFs were age, gender, trauma, underlying diseases, visual acuity (VA) at presentation, bruit, chemosis, and dilated retinal vessels. However, in multivariable analysis, the significant predictors were limited to age, trauma, bruit, underlying diseases and logMAR VA. Regression coefficient of each predictor was converted to a risk score and summation of scores from these predictors for each patient was calculated. The total risk score predicted the urgent direct CCFs correctly with AuROC of 97.77% (95% CI; 93.57, 100).

Conclusion: The clinical risk score for the prediction of urgent direct CCFs has been developed and used in the patients with CCFs in our setting. The discriminative ability of the score prediction is high. This simple clinical risk score may help clinicians suspect direct CCFs and urgently refer the patients to have prompt angiography and treatment.

目的:建立预测颈动脉海绵窦瘘(CCFs)患者急症的临床风险评分,并检验其诊断预测的判别能力。方法:回顾性分析60例CCFs患者的病历资料。采用logistic回归分析直接和硬脑膜CCFs的临床特点。临床风险评分由多变量回归模型中的系数得出,用于预测直接CCFs,后者比硬脑膜型更为紧急。评分预测报告为受试者工作特征(AuROC)曲线下的面积和95%置信区间(95% CI)。结果:在一项单变量分析中,增加直接CCFs风险的临床特征是年龄、性别、创伤、基础疾病、就诊时视力(VA)、瘀伤、化脓和视网膜血管扩张。然而,在多变量分析中,显著的预测因子仅限于年龄、创伤、bruit、基础疾病和logMAR VA。每个预测因子的回归系数转换为风险评分,并计算每个患者这些预测因子的评分总和。总风险评分正确预测紧急直接CCFs, AuROC为97.77% (95% CI;93.57, 100)。结论:用于预测急迫性直接CCFs的临床风险评分已被开发并应用于本院CCFs患者。分数预测的判别能力较高。这个简单的临床风险评分可以帮助临床医生怀疑直接CCFs,并紧急推荐患者及时进行血管造影和治疗。

Background: Glaucoma is a degenerative optic neuropathy that causes anatomical and functional visual impairment.

Aim and objectives: This investigation's primary goal was to perform a qualitative and quantitative assessment of macular and peripapillary vessels to detect the impairment of blood flow in glaucomatous patients with or without myopia which can affect the prognosis of glaucoma and visual field.

Subjects and methods: This prospective, cross-sectional, observational research was performed for glaucomatous patients with and without myopia who attend the outpatient clinic at the ophthalmology department, at Benha University. The study was conducted on 50 subjects with glaucomatous eyes, divided into two groups: the first group consisted of (25 subjects) of glaucoma with myopia and the second group (25 subjects) of glaucoma with the same severity of mean deviation in the visual field of group 1 without myopia, using OCTA to measure retinal vessel density (superficial vessel density) and OCT thickness ILM-RPE, RNFL thickness, GCL and small vessel density (RADIAL PERI PAPILLARY PLEXUS).

Results: Regarding demographic data of myopia in the studied eyes, there were (9) 18% with low myopia with no significance, (32) 64% with moderate myopia, and (9) 18% with high myopia, with open-angle glaucoma patients showed a highly significant decline in total retinal nerve fiber layer thickness, superior-nasal RNFL thickness, Inferior-nasal RNFL thickness, superior-temporal RNFL and inferior-temporal RNFL thickness compared to open-angle glaucoma patients without myopia.

Conclusion: Our results show that microvascular attenuation occurs more significantly in OAG than in myopia. When both myopia and OAG are present, there is a higher reduction in microvascular attenuation than with either disease alone. The development and progression of glaucoma in individuals with high myopia are more aggressive than in low or non-myopia, so by using OCTA detection of early microvascular changes in high myopia, individuals help the early detection and management of glaucoma.

背景:青光眼是一种退行性视神经病变,可引起解剖学和功能性视觉损害。目的和目的:本研究的主要目的是对伴有或不伴有近视的青光眼患者的黄斑和乳头周围血管进行定性和定量评估,以检测影响青光眼预后和视野的血流障碍。对象和方法:这项前瞻性、横断面、观察性研究是在Benha大学眼科门诊就诊的伴有或不伴有近视的青光眼患者中进行的。本研究选取50例青光眼患者,分为两组,第一组(25例)为伴有近视的青光眼,第二组(25例)为视野平均偏差程度与非近视组1相同的青光眼,采用OCTA测量视网膜血管密度(表浅血管密度)和OCT厚度ILM-RPE、RNFL厚度、GCL和小血管密度(桡骨周围乳头丛)。结果:所研究眼睛的近视人口统计学资料中,(9)18%为低近视,无统计学意义;(32)64%为中度近视;(9)18%为高度近视,开角型青光眼患者的视网膜神经纤维总层厚度、上鼻RNFL厚度、下鼻RNFL厚度、上颞RNFL厚度、下颞RNFL厚度均较无近视的开角型青光眼患者有高度显著的下降。结论:我们的研究结果表明,OAG的微血管衰减比近视更明显。当近视和OAG同时存在时,微血管衰减的减少比单独存在任何一种疾病时都要高。高度近视个体青光眼的发展和进展比低度数或非度数个体更具侵袭性,因此通过OCTA检测高度近视个体早期微血管变化,有助于青光眼的早期发现和治疗。

Purpose: To analyze refractive changes after neodymium: yttrium-aluminum-garnet (Nd:YAG) posterior capsulotomy in pseudophakic eyes.

Patients and methods: Patients who underwent Nd:YAG capsulotomy after cataract surgery from January 2013 to April 2022 were included in this retrospective study. Sphere, cylinder, spherical equivalent (SE), axis, and corrected distance visual acuity (CDVA) were compared pre- and postoperatively in 683 eyes of 548 patients at one month (n = 605 eyes) and one year (n = 211 eyes). Patients with both one-month and one-year follow-ups (n = 133) were also compared. Eyes were stratified into single-piece (n = 330), three-piece (n = 30), and light adjustable lenses (LALs) (n = 16). Pre- and postoperative measurements were analyzed within each group.

Results: Cylinder was significantly decreased at one-month (difference: 0.042±0.448 D, p = 0.006) and one-year (difference: 0.101±0.455 D, p = 0.003) compared to preoperative measurements. No significant change in sphere or axis was observed at follow-up visits (p > 0.05). CDVA significantly improved at both time points (p < 0.05). No significant change in any parameters between the one-month and one-year groups was observed (p > 0.05). There was significant improvement in CDVA in the single and three-piece lens groups (p < 0.0001 and p = 0.026, respectively), with no change in the LAL group (p > 0.05).

Conclusion: There were no changes in sphere, axis, or spherical equivalent after Nd:YAG capsulotomy. However, cylindrical error and CDVA were significantly better after the procedure. Lens type did not impact refractive parameters postoperatively.

目的:分析假性晶状体眼后囊切除术后的屈光变化。患者和方法:本研究纳入2013年1月至2022年4月白内障术后行Nd:YAG囊切开术的患者。比较548例患者中683只眼1个月(n = 605眼)和1年(n = 211眼)的球、柱、球当量(SE)、轴和矫正距离视力(CDVA)的术前、术后差异。随访1个月和1年的患者(n = 133)也进行了比较。将眼睛分层分为单片(n = 330)、三片(n = 30)和可调光透镜(LALs) (n = 16)。分析各组术前和术后的测量结果。结果:与术前相比,1个月(差异0.042±0.448 D, p = 0.006)和1年(差异0.101±0.455 D, p = 0.003)圆柱体明显降低。随访时球体和轴向无明显变化(p > 0.05)。CDVA在两个时间点均显著改善(p < 0.05)。1个月组与1年组间各项指标无显著变化(p > 0.05)。单片和三片晶状体组CDVA有显著改善(p < 0.0001和p = 0.026), LAL组无变化(p > 0.05)。结论:Nd:YAG囊膜切开后,球、轴、球等价物无明显变化。然而,手术后柱形误差和CDVA明显改善。晶状体类型对术后屈光参数无影响。
