【摘要】： 目的通过光学相干断层扫描观察视网膜色素变性患者视网膜黄斑部的图像特征以及黄斑中心凹视网膜厚度的变化情况。方法对临床诊断为视网膜色素变性的6例(12只眼)患者进行眼底照相和光学相干断层扫描检查,观察光学相干断层扫描中视网膜黄斑部图像特征,并与眼底照相的结果作对比,同时在光学相干断层扫描中测量黄斑中心凹视网膜厚度。结果 6例(12只眼)视网膜色素变性患者的黄斑中心凹视网膜平均厚度为149.25±45.03um。视网膜色素变性患者在眼底照相结果中未表现出黄斑部的异常,而在光学相干断层扫描检查中视网膜黄斑部图像有以下5种表现：1.视网膜黄斑部水肿,共2例,3只眼(25%),黄斑中心凹视网膜厚度分别为207um、220um、201um；2.视网膜色素上皮层及脉络膜毛细血管层薄变,共2例,3只眼(25%),黄斑中心凹视网膜厚度分别为85um、134um、107um；3.视网膜色素上皮层(RPE)萎缩,共1例,2只眼(16.7%),黄斑中心凹视网膜厚度分别为95um、103um；4.黄斑部视网膜厚度正常,共1例,2只眼(16.7%),黄斑中心凹视网膜厚度分别为175um164um；5.视网膜色素上皮层厚薄分布不一,共1例,2只眼(16.7%),黄斑中心凹视网膜厚度分别为150um、160um 结论光学相干断层扫描能较早发现视网膜色素变性患者黄斑部各种病变,为早期诊断及早期治疗提供临床依据。
[Abstract]:Objective to observe the retinal macular features and retinal thickness of macular fovea in patients with retinitis pigmentosa by optical coherence tomography (OCT). Methods six patients (12 eyes) with retinal pigmentosa were examined by fundus photography and optical coherence tomography (OCT). The retinal thickness of macular fovea was measured by optical coherence tomography. Results the mean retinal thickness of macular fovea was 149.25 卤45.03 umum in 6 cases (12 eyes) with retinitis pigmentosa. Retinal pigmentosa patients showed no macular abnormalities in fundus radiography, but the macular images showed the following 5 types of macular images in optical coherence tomography (OCT). There were 3 eyes (25%) with macular edema, and the retinal thickness of central fovea of macula was 207um / 220um / 201umU 2respectively. The retinal pigment epithelium layer and choroidal capillary layer were thinned in 2 cases (25%). The retinal thickness of central fovea of macula was 85 渭 m 134um / 107um / 3 respectively. The retinal pigment epithelium layer (RPE) atrophied in 1 case (16.7%). The retinal thickness of macular region was normal in 1 case (16.7%), and the retinal thickness of central fovea of macula was 175um 164um / 5 respectively. The thickness and thickness of retinal pigment epithelium are different. The retinal thickness of central fovea of macula was 150 渭 m / 160um respectively. Conclusion all kinds of macular lesions can be detected by optical coherence tomography (OCT) in patients with retinitis pigmentosa. To provide clinical basis for early diagnosis and treatment.
