Abstract

PURPOSE

To report a case of orthokeratology lens-related Pseudomonas corneal ulcer in an adult.

METHODS

Case report.

RESULTS

A 37-year-old man presented with a 1-day history of painful red eye. He was a soft contact lens wearer before he started on nocturnal orthokeratology lens wear of 8 to 10 hours per night 9 months ago. Corneal scraping sent for culture revealed a heavy growth of Pseudomonas aeruginosa. The patient was treated with intensive topical fortified tobramycin and ceftazidime drops. The ulcer healed with a residual paraxial corneal scar. Although his best-corrected visual acuity (BCVA) recovered from finger counting (8/200) at presentation to 20/30, he suffered visual loss from a premorbid BSCVA of 20/15. His contrast sensitivity (Vector Vision CSV 1000 test) performance was also worse than his fellow eye.

CONCLUSION

Nocturnal orthokeratology lens wear may be associated with an increased risk of infection.

摘要

目的

报告一例成人角膜塑形镜相关的铜绿假单胞菌角膜溃疡病例。

方法

病例报告。

结果

一名37岁男性，有1天眼睛疼痛、发红的病史。9个月前，他开始每晚佩戴角膜塑形镜8至10小时，在此之前他一直佩戴软性隐形眼镜。角膜刮片培养显示有大量铜绿假单胞菌生长。患者接受了强化局部使用强化妥布霉素和头孢他啶滴眼液治疗。溃疡愈合后留下了近轴角膜瘢痕。尽管他的最佳矫正视力（BCVA）从就诊时的数指（8/200）恢复到了20/30，但他发病前的最佳矫正视力为20/15，仍有视力损失。他的对比敏感度（Vector Vision CSV 1000测试）表现也比健眼差。
