Vitamin A deficiency leads to a wide spectrum of ocular manifestations ranging from conjunctival xerosis to corneal ulceration and perforation. Penetrating keratoplasty along with vitamin A supplementation can save the eye and useful vision.
A 10-year-old boy presented with decreased vision in both eyes for 3 months. Slit-lamp examination with diffuse light revealed bilateral corneal thinning with iris prolapse at inferior aspect of cornea. He underwent therapeutic penetrating keratoplasty in both eyes. Vitamin A supplementation was given as per national protocol. Till 1 year postoperatively visual acuity in RE was 6/18 and LE was pre-phthisical.
Vitamin A deficiency is potentially a sight threatening condition, which may lead to keratomalacia and corneal perforation if neglected. Timely management with Vitamin A supplementation and penetrating keratoplasty can save the eye and vision.
维生素 A 缺乏可导致广泛的眼部表现，从结膜干燥症到角膜溃疡和穿孔。穿透性角膜移植术联合维生素 A 补充可挽救眼球并保留有用视力。
一名 10 岁男孩因双眼视力下降 3 个月就诊。裂隙灯检查显示双眼角膜变薄，虹膜在下角膜处脱出。他在双眼接受了治疗性穿透性角膜移植术。根据国家方案给予维生素 A 补充。术后 1 年，右眼视力为 6/18，左眼接近失明。
维生素 A 缺乏症具有潜在的致盲风险，如果得不到治疗，可能导致角膜软化和穿孔。及时进行维生素 A 补充和穿透性角膜移植术治疗可以挽救眼球和视力。
