目的：探讨基于问题式教学法(problem-based learning，PBL)联合基于案例教学法(case-based learning，CBL)的模式在留学生眼科学教学中的效果。方法：将教学对象分为两组，其中传统教学组30人，联合教学组35人。传统教学组采用传统授课方法，联合教学组采用PBL联合CBL的教学方法。对其效果进行评估，评估指标包括发言次数、临床思维能力、学习兴趣、教学质量评分、教学满意度、理论分数、病例分析分数等。结果：与传统教学组相比，联合教学组学生在各项评估 指标上均明显优于传统教学组，且各项指标之间的差异均具有统计学意义。结论：PBL与CBL相结合的教学模式能有效提高眼科学教学质量，值得在临床教学中进一步推广应用。

Objective: To investigate the effect of problem-based learning (PBL) and case-based learning teaching (CBL) teaching approaches in the ophthalmology teaching of foreign students. Methods: The subjects were divided into a control group (30 students) and an experimental group (35 students). In the control group, the students were taught via traditional teaching methods. The PBL and CBL teaching approaches were applied in the experimental group. Then, the number of statements, clinical thinking ability, learning interest, teaching quality scores, teaching satisfaction, theoretical scores, and case analysis scores were assessed in these two groups. Results: Compared with the control group, the assessments in the experimental group were significantly better (P<0.05). Conclusion: The PBL and CBL teaching approaches can effectively improve the teaching quality of ophthalmology of foreign students. It is worth to popularize this method in clinical teaching.

目的：探讨中心性晕轮状视网膜脉络膜萎缩不同病变阶段的眼底影像学特征。方法：回顾分析中心性晕轮状视网膜脉络膜萎缩患者眼部检查及眼底荧光血管造影(fundus fluorescein angiography，FFA)检查，分析不同病变阶段荧光素眼底血管造影的影像学特征，总结该病发展转归的临床规律。结果：I期：眼底彩色照相：黄斑区轻度色素紊乱，可累及或未累及中心凹。FFA示：中心凹附近高荧光，RPE和脉络膜毛细血管的萎缩面积及程度尚不足以透见下方粗大的脉络膜血管。II期：眼底可见一类圆形的低色素区域，荧光造影可见与眼底彩照对应的高荧光区，随造影过程延长可见萎缩区荧光素渗漏。III期：黄斑区萎缩灶外围边界模糊，其中可见一部分边界清晰、稳定的完全萎缩灶。FFA：萎缩灶内边界清晰的部分视网膜色素上皮细胞(retinal pigment epithelium，RPE)及脉络膜完全萎缩，周边在造影晚期可见未完全萎缩的脉络膜毛细血管渗漏区域。IV期：黄斑区边界清晰的视网膜脉络膜萎缩灶，黄斑中心凹累及。FFA可见与眼底像相对应的脉络膜萎缩灶，其中可透见粗大的脉络膜血管。周围部分未见活动性荧光素渗漏，病变稳定。结论：荧光素眼底血管造影能反映的脉络膜萎缩程度是不同阶段病变阶段的主要指标。

Objective: To investigate the imaging features of fundus fluorescein angiography in central areolar choroidal dystrophy at different stages. Methods: Ocular examination and fundus fluorescein angiography were carried out, imaging features of fundus ffuorescein angiography were retrospectively analyzed. Results: Stage I: fundus photography showed mild macular pigment disorders, which was involved with the fovea. Fundus fluorescein angiography (FFA): high fluorescence was close to the fovea, the area and the extent of RPE and choroidal capillaries atrophy were insufffcient to see through the thick choroidal vessels beneath. Stage II: fundus showed a round of low pigment area, fluorescein angiography showed high fluorescence corresponding region, with the angiography procedure the ffuorescein leakage could be observed. Stage III: boundaries of macular atrophy lesions were unclear which showed part of a clear boundary, stable completely atrophy lesions. FFA: part of retinal pigment epithelium (RPE) and choroidal uncompletely atrophy surrounded was visible, in the late of angiography choroidal atrophy capillary leakage could be seen. Stage IV: boundary of macular retinal choroidal atrophy was clear, foveal involvement. FFA: choroidal atrophy lesions were clear which could be seen through the thick choroidal vessels. Fluorescein leakage disappeared and the disease was stable. Conclusion: The extend of choroidal atrophy in fundus ffuorescein angiography is an important indictor reflecting the progression of different stages.

This paper summarized the nursing experience of 15 children with self-expanding hydrogel orbital implantation during perioperative period. Before operation, children were fully evaluated, given with psychological care, preoperative preparation and management of fasting and drinking. After the surgery, the patients were mainly given with safety management, diet, pain, medicine and elastic bandage dressing care. Nurses should pay attention to the occurrence of complications and give corresponding nursing care and offer useful discharge guidance for the children and their parents. All 15 children completed the operation successfully, postoperative eye pain occurred in 15 cases after operation, and the orbital pressure increased in 2 cases, 1 case vomited, and all cases were properly treated. After postoperative follow-up for 3–18 months, 15 children were satisfied with the appearance of the eye, and the life quality was improved. 

目的：评估Smart plug泪小管塞治疗水液缺乏型干眼的长期并发症。方法：收集汕头国际眼科中心2011至2016年门诊确诊的水液缺乏型干眼患者300例(600眼)，进行Smart plug泪小管塞治疗，随访观察术后临床并发症，中位随访时间为术后3年(术后1~5年)。结果：3例患者(3眼)术后患有泪小管炎(0.5%)，发病时间为术后1~3(中位2)年，取出泪小管塞后并给予局部抗生素滴眼液治愈。2例患者 (4眼)因植入上下泪小管塞后流泪症状不能耐受，单纯取出下泪小管塞后症状缓解(0.7%)；4例患者(8眼)因只植入下泪小管塞症状未能明显好转，1个月后再次植入上泪小管塞(1.3%)；291例患者干眼主观症状改善，有效率为97.5%，长期随访未发现并发症。结论：虽然Smart plug泪小管塞治疗水液 缺乏型干眼具有明确的疗效，但Smart plug泪小管塞植入后的长期并发症不容忽视，需要长期观察。

Objective: To evaluate the long-term complication associated with the use of the Smart plug in the treatment of aqueous tear deficiency dry eye. Methods: A total of 300 patients (600 eyes) were collected in Joint Shantou International Eye Center from 2011 to 2016, all the patients accepted the treatment with Smart plug, and were followed up for clinical complications. The median follow-up time was postoperative 3 years (1–5 years after surgery). Results: Three patients (3 eyes) developed canaliculitis, the rate was 0.5%. The median time from Smart plug insertion to the onset of canaliculitis was 2 (1–3) years, leaving the Smart plug and resolved the application of topical antibiotics. Two patients (4 eyes) could not suffer from implantation of the upper and lower Smart plug, removed the below, the ratio was 0.7%; 4 patients (8 eyes) need upper Smart plug insertion after implantation of the lower one month later, the rate was 1.3%; 291 cases of dry eye improved by long-term followup, the effective rate was 97.5%. Conclusion: Although the Smart plug is effective in the treatment of aqueous tear deffciency dry eye, the later complications of Smart plug insertion cannot be neglected and need the long-term follow-up.
