The purpose of the study was to characterize the epidemiological profile and average time on the waiting list of patients undergoing an urgent corneal transplantation (CT) in a referral center in the state of Rio Grande do Norte, northeastern Brazil.
This cross-sectional study included cases of urgent corneal transplants performed in a referral center from January 2010 to December 2014. Data were collected between January and March 2015.
Seventy-four cases of emergency CT were analyzed. Of these, 69.4% were male, over the age range from 8 to 92 years. There were 38 transplants occurring in the right eye, 55.4% with tectonic purpose, 25.7% with optical purpose, and 18.9% therapy purpose. The main indications for patient inclusion in an emergency were the perforation (52.7%) and corneal ulcer unresponsive to medical treatment (33.8%). Interstitial keratitis was the most common diagnosis (74.3%), responsible for all prioritized cases in line for corneal ulcer unresponsive to treatment. The average length of the waiting line to perform the urgent CT was 9.03 days.
In this study, there was a predominance of male patients and patients >50 years old, which corroborates the results of other studies with similar results. Perforation was the main indication to include the patient on the urgency list (52.7%). There is a need for further research to improve public health policies on the process of corneal transplantation as well as raising awareness of the importance of organ donation.
本研究旨在描述巴西东北部北里奥格兰德州一家转诊中心接受紧急角膜移植（CT）患者的流行病学特征以及在等待名单上的平均时间。
这项横断面研究纳入了2010年1月至2014年12月在一家转诊中心进行的紧急角膜移植病例。数据于2015年1月至3月收集。
分析了74例紧急角膜移植病例。其中，69.4%为男性，年龄范围在8岁至92岁之间。右眼进行了38例移植，55.4%用于结构目的，25.7%用于光学目的，18.9%用于治疗目的。患者纳入紧急情况的主要指征为穿孔（52.7%）和药物治疗无效的角膜溃疡（33.8%）。间质性角膜炎是最常见的诊断（74.3%），导致所有因药物治疗无效的角膜溃疡而优先排队的病例。进行紧急角膜移植的平均等待时间为9.03天。
在本研究中，男性患者和年龄大于50岁的患者占多数，这与其他结果相似的研究结果相符。穿孔是将患者列入紧急名单的主要指征（52.7%）。需要进一步研究以改善角膜移植过程中的公共卫生政策，并提高对器官捐赠重要性的认识。
