Neurofibromatosis Type I (NF-1) is a neurocutaneous disease affecting the skin, eye and peripheral nervous system. Congenital glaucoma is a rare association, but can be a prelude to the diagnosis of NF-1 later in life. We report this unusual association in a child and discuss the possible underlying pathophysiologic mechanisms.
A nine year old female child on treatment for glaucoma in the right eye was referred to us for definitive management. Her ocular evaluation was remarkable for reduced visual acuity, megalocornea with buphthalmos, congenital ectropionuveae, Lisch nodules and glaucomatous optic neuropathy in the right eye. Systemic evaluation revealed café-au-lait spots on the chest and back. A diagnosis of Neurofibromatosis Type I with congenital ectropion uveae and glaucoma was arrived at and neuroimaging failed to detect any optic pathway gliomas. In view of advanced glaucomatous neuropathy, a conservative therapy was recommended.
Unilateral congenital glaucomas with ectropion uveae are likely to be associated with NF-1. These children should be monitored closely for glaucoma progression and may require neurological evaluation including imaging studies to exclude optic pathway gliomas.
I型神经纤维瘤病(NF-1)是一种影响皮肤、眼睛和周围神经系统的神经皮肤疾病。先天性青光眼是一种罕见的关联情况,但可能是日后诊断NF-1的前奏。我们报告一名儿童中的这种不寻常关联,并讨论可能的潜在病理生理机制。
一名正在接受右眼青光眼治疗的9岁女童被转诊至我们处进行确定性治疗。她的眼部评估结果显著,包括视力下降、角膜增大伴牛眼、先天性葡萄膜外翻、Lisch结节以及右眼青光眼性视神经病变。全身评估发现胸部和背部有咖啡牛奶斑。诊断为I型神经纤维瘤病合并先天性葡萄膜外翻和青光眼,神经影像学检查未发现任何视神经通路胶质瘤。鉴于青光眼性神经病变已进展,建议采取保守治疗。
单侧先天性青光眼合并葡萄膜外翻可能与NF-1相关。这些儿童应密切监测青光眼进展情况,可能需要进行包括影像学检查在内的神经学评估以排除视神经通路胶质瘤。
