Unilateral Punctate Keratitis Secondary to Wallenberg Syndrome

We studied three patients who developed left unilateral punctate keratitis after suffering left-sided Wallenberg Syndrome. A complex evolution occurred in two of them. In all cases, neurophysiological studies showed damage in the trigeminal sensory component at the bulbar level. Corneal involvement secondary to Wallenberg syndrome is a rare cause of unilateral superficial punctate keratitis. The loss of corneal sensitivity caused by trigeminal neuropathy leads to epithelial erosions that are frequently unobserved by the patient, resulting in a high risk of corneal-ulcer development with the possibility of superinfection. Neurophysiological studies can help to locate the anatomical level of damage at the ophthalmic branch of the trigeminal nerve, confirming the suspected etiology of stroke, and demonstrating that prior vascular involvement coincides with the location of trigeminal nerve damage. In some of these patients, oculofacial pain is a distinctive feature.     

Macroperforaciones corneales no infecciosas tratadas con la asociación de TachoSil® y Tutopach®. A propósito de 2 casos

Clinical caseWe report 2 cases of patients affected by non-infectious corneal macroperforations treated with TachoSil^® and Tutopach^®, which closed the defect.DiscussionThis procedure is an excellent choice for the emergency treatment of corneal perforation, especially in those centres that have no other therapeutic options, preserving the eye and visual acuity.     

Early‐onset hypoparathyroidism and chronic keratitis revealing APECED

Early diagnosis of potentially life‐threatening autoimmune polyendocrinopathy‐candidiasis‐ectodermal dystrophy (APECED) is crucial, but is often delayed due to the clinical heterogeneity of the disorder. Even in the absence of the classic disease triad of chronic mucocutaneous candidiasis, hypoparathyroidism, and adrenocortical insufficiency, a diagnosis of APECED should be considered in children who have hypoparathyroidism and chronic keratitis, with a past medical history showing a mild and transient Candida infection.     

Persistence of Efficacy of 0.1% Cyclosporin A Cationic Emulsion in Subjects with Severe Keratitis Due to Dry Eye Disease: A Nonrandomized,Open-label Extension of the SANSIKA Study

Purpose

Results from a 6-month double-masked and a 6-month open-label study (SANSIKA) established the efficacy and safety of once-daily 0.1% cyclosporin A cationic emulsion (CsA CE) in severe keratitis due to dry eye disease (DED). This article presents results from the Post-SANSIKA study, a 24-month extension of SANSIKA assessing the sustained efficacy of CsA CE after treatment discontinuation.

Bilateral Orbital IgG4-Related Disease with Systemic and Corneal Involvement Showing an Excellent Response to Steroid and Rituximab Therapy: Report of a Case with 11 Years Follow-Up

IgG4-related disease is a newly recognized fibro-inflammatory condition. The purpose of this report is to present a patient with 11 years of follow-up, who revealed characteristic features of IgG4-related disease with systemic, orbital and corneal involvement and showed a favorable response to steroids and rituximab treatment.     

重症真菌性角膜炎患者的临床特征分析

目的:探讨重症真菌性角膜炎病因、人群特征及临床特点。方法:搜集2008-01/2013-11就诊于我院眼科的233例233眼重症真菌性角膜炎患者的临床资料,回顾性分析其病因、人群特征、临床特点等情况。结果:重症真菌性角膜炎233例患者中,男153例(65.7%),男女比例约为1.9∶1;年龄分布中,中老年龄段人数居多,平均年龄52.7±11.3岁;居住地多为农村(78.1%);并且其职业以农民为主(66.1%),发病患者文化程度普遍较低(59.7%);重症患者中,188例(80.7%)患者具有明确的眼部外伤史,以植物性外伤为主(60.9%)。主要致病菌属为镰刀菌属,为90例(57.3%),其次为曲霉菌属47例(29.9%);治疗中手术率为87.9%。其中多数行穿透性角膜移植术,为83例(52.9%),在镰刀菌及曲霉菌感染的重症角膜炎患者中,行穿透性角膜移植术者比例较高,为58.4%(80/137);行眼内容剜除术或眼球摘除术的重症患者中,68.4%(13/19)的患者为镰刀菌属感染。结论:我院重症真菌性角膜炎患者多为农村居住的中老年男性农民,可能与其经济条件及诊疗意识差有关。其主要致病菌为镰刀菌及曲霉菌属,穿透性角膜移植手术为主要治疗手段,且预后差的重症患者多为镰刀菌感染。     

与隐形眼镜相关的感染性角膜炎-埃及5年流行病学研究

目的：研究埃及Tanta大学医院与隐形眼镜相关的感染性角膜炎患者的不同流行病学特点,评估这类疾病各方面的特点,以提高患者对这类疾病的认识,找出可行的解决方案。

方法：选取我院2009-01/2013-12期间在眼科门诊就诊的所有角膜炎患者仔细检查,并对所有与隐形眼镜相关的感染性角膜炎患者进一步检查和调查。

结果：本研究期间,总共108 496位有不同主诉的患者中,1463例(1.3%)患有不同形式的角膜炎,其中151例(0.1%)为隐形眼镜相关感染性角膜炎。结果发现患有隐形眼镜相关感染性角膜炎常见的年龄群<30岁,大多数是学生(64%),家庭人数多且较为拥挤,农村居民高于城市居民,患者采用户外水源及污水处理不卫生。从病史分析发现：隐形眼镜相关感染性角膜炎通常为彻夜使用,储存或者配戴不卫生,或者隐形眼镜来源不安全,例如化妆品商店和理发店。结膜囊微生物培养结果提示阳性率92%,阴性率8%。大多数培养阳性的病例是由细菌和真菌混合感染引起,共53例(38.1%),单纯细菌感染43例(30.9%),真菌31例( 22.3%),阿米巴12例(8.6%)。

结论：与隐形眼镜相关的感染性角膜炎常见于学生群体,与农村生活、户外供水、不卫生的污水处理等危险因素有关。彻夜配戴、储存或配戴不卫生及隐形眼镜来源不安全都可增加隐形眼镜相关感染性角膜炎的发病率。
