本文报告两例单眼无痛性视力下降病例。病例1为47岁男性，表现为右眼亚急性视力下降，伴视盘水肿及黄斑区星芒状渗出，血清汉塞巴尔通体（Bartonella henselae）IgG抗体阳性（滴度1:256），结合猫接触史及跳蚤叮咬史，诊断为猫抓病相关视神经视网膜炎。经口服多西环素联合球周注射曲安奈德治疗后，视力显著恢复至1.0。病例2为33岁男性，表现为右眼急性视野缺损伴轻度视力下降，视盘水肿伴出血及棉绒斑。血清学检查示汉塞巴尔通体IgG阳性（滴度1:256）及梅毒螺旋体抗体阳性（TPPA+, TRUST+）。初始经验性抗猫抓病（多西环素+利福平）及抗梅毒（苄星青霉素）治疗无效，视力持续下降。随访1个月时光学相干断层扫描（OCT）显示视盘周围视网膜色素上皮（RPE）局灶性钉状突起，符合梅毒眼部特征性改变，结合患者抗汉塞巴尔通体治疗反应不佳，最终修正诊断为梅毒性视神经病变。继续抗梅毒治疗后视力稳定于0.63，但遗留视神经萎缩。两例病例提示感染性视神经病变的诊断需综合病史、临床表现、辅助检查、治疗反应及特征性体征进行鉴别，尤其需审慎解读汉塞巴尔通体抗体血清学阳性结果。

This paper reports two cases of unilateral painless vision loss. Case 1 involved a 47-year-old male presenting with subacute vision loss in the right eye, accompanied by optic disc edema and macular stellate exudates. Serological testing revealed positive IgG antibodies against Bartonella henselae (titer 1:256). Combined with a history of cat contact and flea bites, a diagnosis of cat scratch disease-associated optic neuroretinitis was made. After treatment with oral doxycycline combined with periocular triamcinolone acetonide injection, the patient's vision significantly improved to 1.0. Case 2 involved a 33-year-old male presenting with acute visual field defect in the right eye accompanied by mild vision loss, optic disc edema with hemorrhage, and cotton-wool spots. Serological tests showed positive IgG antibodies against Bartonella henselae (titer 1:256) and positive antibodies against Treponema pallidum (TPPA+, TRUST+). Initial empirical treatment for cat scratch disease (doxycycline + rifampicin) and syphilis (benzathine penicillin) was ineffective, with continued vision decline. Optical coherence tomography (OCT) at the one-month follow-up revealed focal spiculated protrusions of the retinal pigment epithelium (RPE) around the optic disc, consistent with characteristic ocular changes of syphilis. Considering the patient's poor response to anti-Bartonella henselae treatment, the diagnosis was revised to syphlitic optic neuropathy. After continued anti-syphilis treatment, the patient's vision stabilized at 0.63, but optic atrophy persisted. These two cases suggest that the diagnosis of infectious optic neuropathy requires comprehensive differentiation based on medical history, clinical manifestations, auxiliary examinations, treatment responses, and characteristic signs, with particular caution in interpreting positive serological results for Bartonella henselae antibodies.

目的：探讨口服25%葡萄糖减轻早产极低出生体重儿在第一次早产儿视网膜病眼底检查时的疼痛 的效果。方法：选取2014年9月至2015年8月在广东省妇幼保健院NICU住院的早产极低出生体重儿，随机分为观察组和对照组，观察组在进行第一次早产儿视网膜病眼底检查前2 min，给予25% 葡萄糖溶液1mL口服；对照组未用任何安慰剂。两组患儿眼底检查后分别进行新生儿疼痛量表的 评估。结果：观察组患儿眼底检查后疼痛评分低于对照组(P<0.001)。结论：眼底检查前2 min口服25%葡萄糖溶液1 mL是缓解早产儿视网膜病检查引起的疼痛的有效措施。

Objective: To explore the analgesic effect of oral glucose 25% on preterm and very low birth weight infants for the first time of fundus examination for retinopathy screening. Methods: Cases of preterm and very low birth weight infants in Guangdong Women and Children’s Hospital NICU from February 2014 to January 2015 were randomly divided into observation group and control group. The observation group was given 1 mL of 25% glucose solution by oral 2 min before the first time of retinopathy screening. The control group was given nothing. Pain was evaluated using the Neonatal Infant Pain Scale immediately after the fundus examination in both groups. Results: The NIPS of the observation group was lower than that of the control group (P<0.001). Conclusion: 1 mL of 25% glucose solution given 2 min before fundus examination for retinopathy of prematurity by oral was an effective measure for pain relief.

角膜神经性疼痛(neuropathic corneal pain，NCP)的患者具有眼部及躯体症状，但临床体征不典型，治疗效果不理想。随着干眼诊治的规范化程度不断提升，NCP的患者日益增多。NCP与全身慢性疼痛综合征相互交织。角膜共聚焦显微镜及活体印迹细胞检测可以发现特征性神经形态及相关蛋白改变。NCP的治疗应基于个体化、多学科联合的原则。本文综述近年来，NCP的病因学、病理生理学、综合治疗等取得新的进展以指导临床及转化医学研究。

Patients with neuropathic corneal pain (NCP) have local and physical symptoms, but the clinical signs are atypical,and the treatment is not effect. With the improvement of standardization of diagnosis and treatment of dry eye, the number of patients with NCP has been increasing. The NCP is intertwined with systemic chronic pain syndrome.Corneal confocal microscope and in vivo blot cytology can find the signs of morphology and associated proteins variation. The treatments of NCP should be based on the principle of individualized, multidisciplinary treatment (MDT). This article reviews recent advances in the etiology, pathogenesis, and comprehensive treatment of NCP to guide clinical translational medicine research.
