PURPOSE
To report a case of subretinal gnathostomiasis presenting with progressive subretinal tracts of a living parasite and successfully treated with focal laser photocoagulation.
METHOD
Observational case report.
PATIENT
A 29-year-old Thai male complained of blurred vision and floaters in his left eye for two weeks. An ocular examination showed multiple, whitish, subretinal tracks at the superotemporal retina. After 5 days of oral albendazole, a moving parasite was confirmed by multimodal retinal imaging. An immunoblotting analysis was positive for species.
RESULT
The patient was treated by laser photocoagulation with frequency-doubled Nd:YAG laser around and over the parasite. Oral albendozole was continued and naproxen was prescribed for four weeks. His vision improved to 20/20 and the inflammation subsided completely within three months. The patient has been followed for five years without local and systemic complications.
CONCLUSIONS
Focal laser photocoagulation without systemic steroids could be a successful treatment for active subretinal gnathostomiasis with a satisfactory safety profile in a long-term follow-up.
目的
报告一例视网膜下颚口线虫病病例，该病例表现为活寄生虫所致的进行性视网膜下条索，并通过局部激光光凝成功治愈。
方法
观察性病例报告。
患者
一名29岁泰国男性，主诉左眼视力模糊和有飞蚊症两周。眼部检查发现颞上视网膜有多个白色视网膜下条索。口服阿苯达唑5天后，通过多模式视网膜成像确认有活动的寄生虫。免疫印迹分析对该物种呈阳性。
结果
患者接受了倍频Nd:YAG激光对寄生虫周围及上方进行激光光凝治疗。继续口服阿苯达唑，并开了萘普生服用四周。他的视力提高到20/20，炎症在三个月内完全消退。该患者已随访五年，无局部和全身并发症。
结论
在长期随访中，不使用全身类固醇的局部激光光凝可能是治疗活动性视网膜下颚口线虫病的成功方法，且安全性良好。
