To report a case of a child with neovascular and ghost cell glaucoma in the setting of previously treated vitreous hemorrhage with unique fluorescein leakage from abnormal iris vessels ultimately preventing successful fluorescein angiography.
A 3-year-9-month-old female with a medical history of very high-risk B-cell acute lymphoblastic leukemia presented with eye pain and was noted to have a complete vitreous hemorrhage and intraocular pressure elevation in the right eye which was refractory to maximum medical therapy and vitrectomy. Following vitreous hemorrhage resolution, an examination under anesthesia with fluorescein angiography was found to have diffuse leakage of fluorescein into the anterior chamber, presumably due to the active iris neovascularization. This anterior chamber fluorescein signal prevented visualization of the retinal vasculature. The patient was diagnosed with mixed mechanism glaucoma (neovascular and ghost cell) due to a resolved vitreous hemorrhage in the setting of a presumed prior ischemic event.
We report a case of an unsuccessful fluorescein angiogram in the setting of anterior chamber fluorescein leakage due to active iris neovascularization, and review considerations for the differential diagnosis and useful diagnostic tests in this clinical scenario.
报告一例儿童患者,在既往治疗过的玻璃体积血背景下发生新生血管性和血影细胞性青光眼,异常虹膜血管出现独特的荧光素渗漏,最终导致荧光素血管造影未能成功进行。
一名3岁9个月大的女性,有极高危B细胞急性淋巴细胞白血病病史,出现眼痛,检查发现右眼完全玻璃体积血且眼压升高,最大药物治疗和玻璃体切割术均无效。玻璃体积血吸收后,麻醉下进行荧光素血管造影检查发现荧光素弥漫渗漏至前房,推测是由于活跃的虹膜新生血管所致。这种前房荧光素信号妨碍了视网膜血管系统的可视化。该患者因既往推测有缺血事件背景下的玻璃体积血吸收,被诊断为混合机制性青光眼(新生血管性和血影细胞性)。
我们报告了一例因活跃的虹膜新生血管导致前房荧光素渗漏而荧光素血管造影失败的病例,并回顾了该临床情况下鉴别诊断的注意事项和有用的诊断检查。
