PURPOSE
To describe a patient with Thygeson's superficial punctate keratitis who underwent photorefractive keratectomy for the correction of myopia.
METHODS
A 49-year-old woman with unilateral Thygeson's keratitis was examined before and after photorefractive keratectomy.
RESULTS
A myopic patient underwent photorefractive keratectomy in the left eye and gained 20/20 uncorrected visual acuity. Seventeen months after surgery, symptomatic Thygeson's keratitis lesions recurred in the peripheral but not the central cornea.
CONCLUSION
Photorefractive keratectomy reliably corrected myopia in a patient with previous Thygeson's keratitis. The recurrence of lesions only in the peripheral untreated cornea suggests that the inflammatory signal in Thygeson's keratitis may reside in the superficial corneal stroma.
目的
描述一名患有蒂格森浅层点状角膜炎的患者，该患者接受了准分子激光角膜切削术以矫正近视。
方法
对一名患有单侧蒂格森角膜炎的49岁女性在准分子激光角膜切削术前和术后进行了检查。
结果
一名近视患者左眼接受了准分子激光角膜切削术，裸眼视力达到了20/20。术后17个月，有症状的蒂格森角膜炎病变在周边角膜而非中央角膜复发。
结论
准分子激光角膜切削术可靠地矫正了一名既往患有蒂格森角膜炎患者的近视。仅在周边未治疗角膜出现病变复发提示，蒂格森角膜炎的炎症信号可能存在于角膜浅层基质中。
