It is responsible in addition to the general symptoms, vitamin A deficiency which can cause serious eye damage including keratomalacia. This work aims to study possible ophthalmological lesions in severely acutely malnourished children from 0 to 60 months. Patients and Method: This study was carried out in a secondary ophthalmology center. It concerned all severely acute malnourished patients admitted for consultation in the pediatric department. Results: A total of 174 eyes of 87 children aged 0 to 60 months were examined. Two-thirds of the patients were aged between 6 and 18 months. Palpebral lesions are rare, however, we observed 12.64% blepharitis and palpebral dermatitis. Ocular involvement due to vitamin A deficiency was 6.9%, including one case of BITOT SPOT, 4 cases of conjunctival xerosis and one case of keratomalacia. Conclusion: Xerophthalmia is an ocular lesion due to a dietary intake deficient in vitamin A that occurs during severe acute malnutrition. Its occurrence is increasingly rare even in developing countries. However, some cases are observed in practice and may be responsible for profound visual impairments.展开更多

文摘目的探讨重组牛碱性成纤维细胞生长因子(recombinant bovine basic fibroblast growth factor,rb-bFGF)滴眼液对白内障术后干眼症患者泪液分泌、角膜损伤和氧化应激指标水平的影响。方法选取接受白内障手术并出现干眼症的患者120例作为研究对象,用随机数字表法分为观察组和对照组,每组60例。对照组用聚乙二醇滴眼液治疗,观察组在此基础上加用rb-bFGF滴眼液治疗。比较2组治疗前和治疗后泪液分泌量[SchirmerⅠ试验(SchirmerⅠtest,SIT)]、角膜损伤程度[角膜荧光素染色(fluorescein staining of the cornea,FL)评分]、泪膜破裂时间(tear film break up time,BUT)和氧化应激指标[超氧化物歧化酶(superoxide dismutase,SOD)、丙二醛(malonaldehyde,MDA)和过氧化脂质(lipid peroxide,LPO)],并对临床疗效及安全性进行评价。结果观察组的总有效率高于对照组(P>0.05)。治疗后,2组SIT、FL评分、BUT和氧化应激指标均改善(P<0.05),且观察组改善效果更佳(P<0.05)。2组不良反应发生情况比较差异无统计学意义(P>0.05)。结论rb-bFGF滴眼液治疗白内障手术后干眼症疗效确切,可显著促进患者泪液分泌,减轻角膜损伤,延长泪膜破裂时间,改善氧化应激指标的水平。
