目的：了解中国华南地区眼科患者近年术前四项指标的感染状况及阳性患者在不同眼病中的分布。方法：回顾性分析2017年1月~2023年12月在中山大学中山眼科中心进行乙型肝炎表面抗原(HBsAg)、丙肝肝炎病毒抗体(抗-HCV)、梅毒螺旋体抗体(抗-TP)、人类免疫缺陷病毒抗体(抗-HIV)指标筛查的门诊、手术和(或)住院患者资料，并记录和分析患者各项指标的阳性情况。结果：共纳入253 246例患者，HBsAg、抗-HCV、抗-TP和抗-HIV阳性率分别是9.00%、0.45%、1.55%、0.13%。两种或两种以上感染指标阳性的患者共有686例， HBsAg和抗HCV同时阳性的例数最高(57.29%)，其次为抗-HIV和抗-TP(15.74%)。2017~2023年HBsAg阳性率逐年递减，而抗-HCV、抗-HIV、抗-TP阳性率变化不明显。男性的HBsAg、抗-HCV、抗-TP、抗-HIV阳性率均高于女性，差异均有统计学意义(P <0.001)。HBsAg、抗-HCV、抗-TP、抗-HIV阳性率在不同年龄段比较差异均有统计学意义(P <0.001)。在HBsAg、抗-HCV、抗-TP阳性患者中，晶状体病的病例数占比最高，分别为36.72%、39.12%、46.97%。其次是玻璃体/视网膜疾病，占比分别为22.52%、19.65%、19.69%。在抗-HIV阳性患者中，玻璃体/视网膜疾病的病例数占比最高，为42.99%，其次是晶状体病，占26.17%，葡萄膜炎占8.72%。结论：本研究揭示了眼科患者术前四项指标的感染情况及感染患者在不同眼病中的分布，这对于评估眼科手术风险、制定感染控制措施具有重要意义。

Objective: To understand the infection status of four blood-borne pathogens among ophthalmology patients in South China and the distribution of positive patients across different eye diseases. Methods: A retrospective analysis of data from outpatient and inpatient or surgical ophthalmic patients who underwent screening for hepatitis B surface antigen (HBsAg), hepatitis C virus antibody (anti-HCV), treponema pallidum antibody (anti-TP) and human immunodeficiency virus antibody (anti-HIV) at Zhongshan Ophthalmic Center of Sun Yat-sen University from January 2017 to December 2023. The positivity rates of these markers were recorded and analyzed. Results: A total of 253246 patients were included in the study, with positivity rates for HBsAg, anti-HCV, anti-TP, and anti-HIV at 9.00%, 0.45%, 1.55% and 0.13%, respectively. Among these, 686 patients tested positive for two or more markers, with the highest co-positivity observed for HBsAg and anti-HCV (57.29%), followed by anti-HIV and anti-TP (15.74%). The positivity rate of HBsAg showed a yearly decline, while the rates for anti-HCV, anti-HIV, and anti-TP remained relatively stable from 2017 to 2023. Males had significantly higher positivity rates for HBsAg, anti-HCV, anti-TP, and anti-HIV compared to females (P < 0.001). Significant differences in positivity rates for these markers were also observed across different age groups (P < 0.001). In patients with positive HBsAg, anti-HCV, and anti-TP, the proportion of cases with lens diseases were the highest, at 36.72%, 39.12%, and 46.97%, respectively. Vitreoretinal diseases followed, with proportions of 22.52%, 19.65%, and 19.69%, respectively. Among patients with positive anti-HIV, the proportion of cases with vitreoretinal diseases was the highest, at 42.99%, followed by lens diseases at 26.17%, and uveitis at 8.72%. Conclusions: This study reveals the infection status of four blood-borne pathogens in ophthalmology patients and the distribution of infected patients across different eye diseases, which is significant for assessing the risks of ophthalmic surgery and formulating infection control measures.

目的：回顾2型神经纤维瘤病(neurofibromatosis type 2, NF2)患者的眼部表现，分析NF2眼部病变的临床和影像学特征，以助该病的早期诊断。方法：收集来自深圳市眼科医院的1例和来自中山眼科中心的3例NF2患者完整的临床资料并进行总结分析。结果：这4例患者均因眼部异常首诊于眼科且符合曼彻斯特诊断标准。4例患者中，3例为NF2早发型(<20岁)，1例为晚发型(>20岁)，男女比例1∶1。3例患者因视力下降、1例患者因复视首诊于眼科。3例行眼底光学相干断层成像(optical coherence tomography, OCT)检查显示，视网膜错构瘤2例，视网膜前膜2例，视盘隆起2例，视网膜神经纤维层和节细胞层变薄1例。其他表现包括麻痹性斜视2例，复视1例，白内障1例，球后段视神经增粗1例，眼眶肿瘤1例。结论：NF2的眼部表现多种多样，可出现在神经症状和听力损失之前。详细的眼科检查及影像学检查对年轻患者的早期诊断非常有价值，有助于选择更好的治疗计划。

Objective: Review the ocular manifestations of patients with neurofibromatosis type 2 (NF2), and analyze the clinical and imaging features of the ocular lesions in NF2, so as to facilitate the early diagnosis of this disease. Methods: The complete medical records of 1 case from Shenzhen Eye Hospital and 3 cases of NF2 from Zhongshan Ophthalmic Center were collected. Results: All four patients were first diagnosed in ophthalmology due to eye symptoms and met the Manchester diagnostic criteria. Of the four patients, three were NF2 early hairstyles (<20 years old), one was late hairstyle (>20 years old), and the male-to-female ratio was 1:1. Three patients were first diagnosed in the ophthalmology department due to decreased visual acuity, and one patient was first diagnosed due to diplopia. Optical coherence tomography (OCT) examinations were performed on three patients, which showed that there were two cases of retinal hamartoma, two cases of epiretinal membrane, two cases of optic disc elevation, and one case of thinning of the retinal nerve fiber layer and ganglion cell layer. Other manifestations included two cases of paralytic strabismus, one case of diplopia, one case of cataract, one case of thickening of the retrobulbar optic nerve, and one case of orbital tumor. Conclusions: The ocular manifestations of NF2 are diverse and can precede neurological symptoms and hearing loss. Detailed ophthalmic examinations and imaging studies are highly valuable for early diagnosis in young patients, aiding in the selection of a better treatment plan.
