To describe imaging findings and encourage the use of distilled water as an adjuvant osmolytic in the surgical management of corneal intrastromal cysts.
A five-year-old female with no history of ocular trauma presented with a visually significant corneal opacity of the left eye. She was diagnosed with a presumed corneal intrastromal cyst and underwent surgical excision with distilled water osmolysis of the cyst cavity.
Optical coherence tomography (OCT) can confirm diagnosis of intrastromal cysts. Presumed epithelial cell nests remain visible at post-operative month eight, with no evidence for cyst recurrence. The authors propose that OCT findings are pathognomonic for corneal intrastromal cysts and that cyst excision combined with distilled water osmolysis at the time of debridement may be beneficial in conserving tissue integrity.
描述影像学表现，并鼓励在角膜基质内囊肿的手术治疗中使用蒸馏水作为辅助性渗透压溶解剂。
一名无眼外伤史的5岁女性，左眼出现明显影响视力的角膜混浊。她被诊断为疑似角膜基质内囊肿，并接受了囊肿腔蒸馏水渗透压溶解的手术切除。
光学相干断层扫描（OCT）可确诊基质内囊肿。术后8个月仍可见疑似上皮细胞巢，无囊肿复发迹象。作者提出，OCT表现对角膜基质内囊肿具有诊断意义，在清创时囊肿切除联合蒸馏水渗透压溶解可能有助于保留组织完整性。
