病理性近视眼底荧光造影分析

目的:观察病理性近视的荧光素眼底血管造影(FFA)的特征.方法:选择-8.00D以上病理性近视患者共80例106眼行FFA检查,根据造影表现结合眼科常规检查情况进行分析.结果:造影显示视神经乳头出现异常荧光者21眼(19.8%).视网膜出现局灶性窗口样荧光32眼(30.2%),局灶性墨汁样渗漏荧光20眼(18.9%),局灶性荧光遮蔽18眼(17.0%).黄斑区的局灶性荧光遮蔽15眼(14.2%),局灶性荧光渗漏12眼(11.3%).视网膜血管的异常荧光共10眼(9.4%).视网膜下脉络膜新生血管25眼(23.6%),发生在黄斑区、后极部和周边部,呈单一或多发病灶.结论:病理性近视视网膜脉络膜呈现复杂多样的病变特征,尤其是脉络膜新生血管多发危害大,FFA为临床干预治疗提供依据.

Analysis of fundus fluorescein angiography features in pathologic myopia

AIM:To investigate the fundus features of pathologic myopia(PM) by using fundus fluorescein angiography(FFA).METHODS:A total of 106 eyes of 80 patients with refractive error higher than-8.00D were performed with FFA.Photos of FFA were analyzed and compared with the outcome of routine examination.RESULTS:Using FFA,the optic papilla were found to appear as hypo-or hyperfluorescence in 21eyes(19.8%).Window defects appeared in 32 eyes(30.2%),fluorescein leakage in 20 eyes(18.9%) and masking within the retina in 18 eyes(17.0%).Fifteen eyes(14.2%) showed local masking at the macula and 12 eyes(11.3%) had fluorescein leakage.Vascular abnormalities were found in 10 eyes(9.4%),and 25 eyes(23.6%) were combined with submacular choroidal neovascularization(CNV) as single or multiple focus spreading on the macula,posterior pole and the peripheral retina.CONCLUSION:Chorioretinal eaxminations of pathologic myopia show complicated features,and the multiple CNV causes severe damage to the visual function.FFA can provide the evidences for the clinical intervention.
