To report the effect of antivascular endothelial growth factor therapy for choroidal neovascularisation associated with deferoxamine toxicity.
In an interventional case report, intravitreal antivascular endothelial growth factor therapy was used for the treatment of a choroidal neovascularization in a patient with deferoxamine retinopathy.
A 54-year-old woman with beta-thalassemia intermedia and known deferoxamine toxicity presented with recent vision loss to the left eye secondary to a choroidal neovascular membrane. Visual acuity had decreased from 20/30 to 20/80 in the left eye. Funduscopic examination and fluorescein angiography revealed diffuse retinal pigment epithelial mottling and a choroidal neovascular membrane. Treatment with three doses of intravitreal bevacizumab led to a good structural outcome and improvement of the visual acuity. The patient later developed a choroidal neovascular membrane in the right eye. Similar treatment with intravitreal bevacizumab also led to a rapid structural resolution of the lesion, albeit with a more modest improvement in the visual acuity.
Therapy with intravitreal bevacizumab might be an option for the treatment of choroidal neovascularization in the context of deferoxamine toxicity.
报告抗血管内皮生长因子疗法对与去铁胺毒性相关的脉络膜新生血管形成的疗效。
在一份介入性病例报告中,玻璃体内抗血管内皮生长因子疗法被用于治疗一名患有去铁胺视网膜病变患者的脉络膜新生血管。
一名54岁患有中间型β地中海贫血且已知有去铁胺毒性的女性,因脉络膜新生血管膜继发近期左眼视力丧失前来就诊。左眼视力从20/30下降至20/80。眼底检查和荧光素血管造影显示弥漫性视网膜色素上皮斑驳及脉络膜新生血管膜。三次玻璃体内注射贝伐单抗治疗带来了良好的结构转归及视力改善。该患者随后右眼出现脉络膜新生血管膜。同样采用玻璃体内贝伐单抗进行治疗也使病变迅速获得结构上的消退,尽管视力改善程度较为有限。
玻璃体内注射贝伐单抗疗法可能是治疗去铁胺毒性所致脉络膜新生血管形成的一种选择。
