摘　　要：目的分析局部脉络膜陷凹光相干断层扫描(OCT)扫描图像特点。方法使用海德堡视网膜断层扫描仪(HRTΠ)回顾性分析局部脉络膜陷凹患者17例18眼21处病灶,研究患者的年龄、性别、眼别、屈光状态及伴发疾病情况,分析病灶的位置、大小、分型、形态IS/OS反光带完整性以及伴发疾病情况。结果患者年龄16~64岁,平均(38.3±11.5)岁;男性5例(5眼),女性12例(13眼);屈光状态+1.33^-8.36D,平均(-3.27±2.92)D;双眼发病1例(5.88%);多灶性发病2例(11.11%);病灶宽度117~2049μm、平均(710.0±464.5)μm;病灶深度23~158μm、平均(74.3±39.1)μm;Ⅰ型14处(66.67%)其中2处病灶伴发脉络膜新生血管,Ⅱ型7处(33.33%)其中5处病灶伴发脉络膜新生血管;8处病灶IS/OS反光带不完整(38.10%),其中7处伴发脉络膜新生血管(87.5%)。结论局部脉络膜陷凹可以见于各个年龄段,多为单眼但也可以是双眼发病,多为单发但也可以是多发的,患者多为近视,病灶的大小、深度变异大,Ⅱ型比Ⅰ型更容易伴发脉络膜新生血管(P<0.05),Ⅱ型的或者伴有IS/OS层破坏的患者更需要积极的随访或者治疗。Objective To evaluate imaging features of focal choroidal excavation with optical coherence tomography（OCT）. Methods A retrospective study among 17 focal choroidal excavation patients （including 18 eyes, 21 lesions） with Heidelberg retina tomography （HRTII） was conducted. This study demonstrated the characteristics of age, gender, dominant eye, refraction concomitant diseases among patients, and analyzed the location, size, classiifcation, morphology of lesions, as well as the IS/OS layer integrity. Results In our study, the age of 17 patients （5 males and 12 females） ranged from 16 to 64 years with an average age of （38.3±11.5） years old, the refraction ranged from ＋1.33 to -8.26 D with A mean value of （-3.27±2.92）D. 1 out of 17 patients exhibited bilateral lesions while multifocal lesions were found in 2 patients. The width of lesions ranged from 117 to 2049 μm with a mean value of （710.0±464.5）μm. The depth ranges from 23 to 158 μm with a mean value of （74.3±39.1）μm. Among 21 lesions, type Ⅰ and type Ⅱ lesions were accounted for 66.67% （14） and 33.33% （7） respectively, 2 of type Ⅰ and 5 of type Ⅱ lesions were accompanied by choroidal neovascularization. 8 out of 21 （38.10%） lesions showed impaired IS/OS relfectivity, 7 of which （87.5%） were accompanied by choroidal neovascularization. Conclusion Focal choroidal excavation may occur through all ages, either laterally or bilaterally. Most of the lesions are solitary while a few multifocal lesions are also showed. Most patients have myopia, exhibiting lesions with variable size and depth. Patients with Type Ⅱ lesions are prone to have choroidal neovascularization. It＆#39;s crucial for this group of patients with or without impaired IS/OS layer integrity to get intensive treatment and follow-up.
