PURPOSE
To report a case of visual field defect associated with laser in situ keratomileusis.
METHODS
Case report. A 28-year-old woman with high myopia (-10D) and a family history of normal tension glaucoma underwent bilateral laser in situ keratomileusis keratorefractive surgery. Preoperatively, both eyes had normal intraocular pressure and visual field.
RESULTS
At the first postoperative visit 1 day after apparently uncomplicated laser in situ keratomileusis, the patient reported a scotoma in the right eye. At 3-month follow-up, visual fields revealed the patient had developed a near-superior altitudinal visual field defect in the right eye. The defect did not progress over 1 year of follow-up examinations.
CONCLUSION
Increased intraocular pressure associated with the microkeratome vacuum ring used during laser in situ keratomileusis may have precipitated optic nerve head ischemia and visual field defect.
目的
报告一例与准分子原位角膜磨镶术相关的视野缺损病例。
方法
病例报告。一名28岁高度近视（-10D）且有正常眼压性青光眼家族史的女性接受了双眼准分子原位角膜磨镶术角膜屈光手术。术前，双眼眼压和视野均正常。
结果
在表面看似无并发症的准分子原位角膜磨镶术后1天的首次术后随访中，患者报告右眼有暗点。在3个月的随访中，视野检查显示患者右眼出现了近乎上方的高度视野缺损。在1年的随访检查中，该缺损未进展。
结论
准分子原位角膜磨镶术中使用的微型角膜刀真空环相关的眼压升高可能引发了视神经乳头缺血和视野缺损。
