摘　　要：目的　探讨不伴脉络膜新生血管 (CNV)的高度近视黄斑出血的眼底改变特征和视力预后。方法　对 3 7例(3 8眼 )不伴CNV的高度近视黄斑出血患者行眼底彩色照相和荧光素眼底血管造影 (FFA)及矫正视力的随访观察 ,其中11例 (11眼 )行吲哚菁绿血管造影 (ICGA)检查。结果　 84 2 %的患眼在出血吸收后于原出血下方可见新的漆样裂纹形成 ;行ICGA的 11只患眼中 ,7眼 (63 6% )于ICGA可透过出血发现呈弱荧光条索的早期漆样裂纹。 81 6%的患眼于出血吸收后视力均有明显增进。结论　不伴CNV的高度近视黄斑出血与新漆样裂纹形成相关 ,建议称之为漆样裂纹性黄斑出血。ObjectiveTo analyze and e valuate the fundus characteristics and visual prognosis of macular hemorrhage in pathological myopia with lacquer crack.MethodsThirty-seven patients (38 ey es) of pathological myopia with macular hemorrhage and without choroidal neovasc ularization (CNV) underwent color photographs and fundus fluorescein angiography (FFA) examination.Indocyanine green angiography (ICGA) were also performed on 11 patients (11 eyes).Follow-up ranged from 3 to 21 months.ResultsThe macul ar hemorrhage without CNV showed oval-shape lesion with the size of <1 PD, and no edema and exudation were seen in pathological myopia.Lacquer cracks appeare d at the site of previous subretinal bleeding in 84 2% of the eyes.The visual a cuities were improved in 81 6% of eyes during the follow-up period.ICGA reveal ed linear hypofluorescence in 7 of 11 eyes (63 6%),indicating a ruptured Bruch 's membrance at the onset of subretinal bleeding.ConclusionA rupture of cho riocapillaris complex and Bruch's membrane causes macular hemorrhage of patholo gical myopia without CNV,leading to the formation of a new lacquer crack.Its pro gnosis is favorable.
