To analysis and evaluate the fundus characteristics and visual prognosis of macular hemorrhage in pathological myopia without choroidal neovasculopathy.
Thirty-seven patients (38 eyes) of pathological myopia with macular hemorrhage and without choroidal neovascularization (CNV) underwent color photograph and fundus fluorescein angiography (FFA) examinations. Indocyanine green angiography (ICGA) was also performed on 11 patients (11 eyes). Follow-up ranged from 3 to 21 months.
The macular hemorrhage in pathological myopia without CNV demonstrated oval, less than 1PD, without edema and exudation. Lacquer cracks appeared at the site of previous subretinal bleeding in 84.2% of the eyes. The visual acuities were improved in 81.6% of eyes during the follow-up period. ICGA revealed linear hypofluorescence in 7 of 11 eyes (63.6%), indicating a ruptured Bruch's membrance at the onset of subretinal bleeding.
A rupture of choriocapillaris complex and Bruch's membrane causes macular hemorrhage of pathological myopia without CNV, leading to the formation of a new lacquer crack. Its prognosis is favorable.
分析和评估无脉络膜新生血管的病理性近视黄斑出血的眼底特征及视力预后。
对37例(38只眼)无脉络膜新生血管(CNV)的病理性近视黄斑出血患者进行彩色眼底照相和眼底荧光血管造影(FFA)检查。11例(11只眼)患者还进行了吲哚菁绿血管造影(ICGA)。随访时间为3至21个月。
无CNV的病理性近视黄斑出血表现为椭圆形,直径小于1视盘直径(1PD),无水肿和渗出。84.2%的患眼在既往视网膜下出血部位出现漆裂纹。随访期间81.6%的患眼视力提高。ICGA显示11只眼中7只(63.6%)有线性低荧光,提示视网膜下出血开始时 Bruch 膜破裂。
脉络膜毛细血管复合体和 Bruch 膜破裂导致无CNV的病理性近视黄斑出血,进而形成新的漆裂纹。其预后良好。
