摘要目的 采用眼前节全景OCT研究蚕蚀性角膜溃疡发生隐匿性穿孔的情况,为临床诊治提供依据.方法 采用眼前段全景OCT观察蚕蚀性角膜溃疡,发现溃疡灶内口角膜组织缺损则定为隐匿性穿孔,并测量穿孔内径.结果 眼前节全景OCT发现蚕蚀性角膜溃疡隐匿性穿孔的发生率为8.3％,穿孔内口直径最小为1.8 mm,最大为4.5 mm,平均为(3.1±0.97) mm.结论 对蚕蚀性角膜溃疡患者进行眼前节全景OCT检查,有助于发现隐匿性穿孔的情况,对于评估患者的预后及手术方案的设计有重要作用.

abstractsObjective To study the occult perforation in Mooren's ulcer by anterior segment OCT,and provide the basis for clinical diagnosis and treatment.Methods Defined the inner lesions of Mooren's ulcer as the occult perforation by anterior segment OCT,and measured the perforated inner diameter.Results The occult perforation rate of Mooren's ulcer were 8.3％,the minimum inner diameter of occult perforation was 1.8mm,the maximum inner diameter of that was 4.5mm,average of that was 3.1 ± 0.97mm.Conclusions It's helping to identify occult perforation of Mooren' s ulcer by anterior segment OCT,and has an important role for the assessment of the patient's prognosis and surgery program design.
