摘要
目的通过相干光断层成像(optical coherence tomography,OCT)观察原发性视网膜色素变性(retinitis pigmentosa,RP)患者的视网膜黄斑区图像特征。方法对临床诊断为原发性视网膜色素变性的25例50只眼进行相干光断层成像检查,观察形态特点并进行厚度测量。结果原发性视网膜色素变性患者黄斑区的相干光断层图像,通常有6种表现:1.神经上皮层弥漫性增厚即水肿(厚度>170μm),13只眼(26%)。2.黄斑囊样水肿8只眼(16.7%)。3.神经上皮层萎缩薄变(<120μm),18只眼(36%)。4.视网膜色素上皮层和脉络膜毛细血管层萎缩薄变,见于所有患者。5.黄斑前膜4只眼(8%)。6.黄斑正常厚度。结论相干光断层成像有助于较早地发现RP的各种黄斑病变,是很有用的检查方法。
Objective To observe the characteristic of macular in patients with retinitis pigmentosa (RP) by optical coherence tomography (OCT). Methods Twenty - five patients of RP were examined to measure the thickess of macular by OCT. Results CKT images of macular in patients with retinitis pigrnentcxsa (RP) have six kinds of expressions: l.the edema of the neurosensory retina (thickness 〉 170μm), 13eyes (26%). 2. cystoid macular edema, eight eyes ( 16% ). 3. the thinning of the neurosensory retina ( thickness〈 120μm), right eyes ( 16% ). 4. retinal pigment epithelium and choroidal capillary vessel are observed in all patients. 5. epiretinal membrane, four eyes (8%). 6. normal thickness of macular. Conclusions OCT is eligible to find the chancre of macular in RP patients. It is a useful tool for doctors in clinic work.
