Corneal neovascularization (CNV) has a variety of causes and threatens corneal clarity, thus optimal visual acuity. Conventional medical management includes topical steroids and matrix metalloproteinase inhibitors like doxycycline. Anti-vascular endothelial growth factor (anti-VEGF) agents have demonstrated promise but remain off-label for this indication. However, these agents hold value in cases refractory to first-line medical management. We report the case of a 63-year-old woman who presented with ocular rosacea and CNV affecting vision, on a background of acne rosacea. She was initially treated with fluorometholone and doxycycline, yet continued to deteriorate. Eventually she received two 1.5-mg subconjunctival injections of bevacizumab 2 months apart. CNV completely resolved and results were maintained at 4-year follow-up. This case demonstrates that refractory CNV can be effectively treated with subconjunctival injection of anti-VEGF bevacizumab. The resolution of CNV was also maintained years after injection with minimal adjunctive therapy during this period, and to our knowledge there are no other studies reporting a follow-up period of 4 years after treatment. This is a pertinent case for other clinicians treating patients in a similar situation.
角膜新生血管化(CNV)有多种病因,会威胁角膜透明度,进而影响最佳视力。传统的药物治疗包括局部使用类固醇和基质金属蛋白酶抑制剂,如强力霉素。抗血管内皮生长因子(抗VEGF)药物已显示出前景,但在此适应症上仍属非适应证用药。然而,这些药物在一线药物治疗无效的病例中具有价值。我们报告了一例63岁女性患者,她患有眼部酒渣鼻和影响视力的CNV,基础疾病为酒渣鼻痤疮。她最初接受氟米龙和强力霉素治疗,但病情仍持续恶化。最终,她在两个月内接受了两次结膜下注射1.5毫克贝伐单抗。CNV完全消退,在4年的随访中结果得以维持。该病例表明,结膜下注射抗VEGF贝伐单抗可有效治疗难治性CNV。注射后数年,CNV消退情况得以维持,在此期间辅助治疗极少,据我们所知,没有其他研究报道治疗后4年的随访期。这对其他治疗类似情况患者的临床医生来说是一个相关病例。
