目的 :探讨光学相干断层成像术 (OCT)在诊断高度近视眼合并黄斑裂孔中的作用。方法 :选取 2 0 0 0年 9月～2 0 0 1年 5月在门诊就诊的高度近视眼患者怀疑黄斑裂孔的病例 2 2例 2 8只眼进行OCT检查 ,散瞳后 ,选用 4mm长的扫描线对黄斑进行线性扫描。结果 :2 2例高度近视眼患者中 ,眼底检查均有不同程度的后极部脉络膜萎缩灶 ,其中 12人 16只眼伴有后巩膜葡萄肿 ;2 8只临床怀疑黄斑裂孔的眼中 ,2 0只眼黄斑全层裂孔 ,3只眼为板层孔 ,3只眼为黄斑囊样变性 ,2只眼为黄斑裂孔合并黄斑前膜 ;2 8只眼中 2 1只眼伴有不同程度的视网膜脱离。结论 :OCT作为一种新型的临床检查手段 ,对于高度近视眼合并黄斑裂孔的早期诊断和鉴别诊断 ,监测病情转归 ,以及选择治疗手段 ,具有重要的临床应用意义。
Objective: To investigate the role of optical coherence tomography (OCT) in the diagnosis of high myopia with macular hole. Methods: The cases of suspected macular hole in high myopia patients treated in the outpatient department from September 2000 to May 2001 were selected. Twenty-two patients (28 eyes) with OCT were examined by OCT. After dilation, a 4mm long Scanning line A linear scan of the macula. Results: Of the 2 2 cases of high myopia, fundus examination had different degrees of posterior pole choroidal atrophy, of which 12 eyes were associated with posterior staphyloma in 16 eyes. In the eyes of 28 clinically suspected macular holes, 20 There were 3 eyes with lamellar holes, 3 eyes with cystoid macular degeneration, 2 eyes with macular hole combined with macular membrane, and 21 eyes with retinal detachment in 28 eyes . Conclusion: As a new clinical examination method, OCT is of great clinical significance for the early diagnosis and differential diagnosis of macular hole with high myopia, monitoring the prognosis of disease and selecting the treatment method.
