This study aims to describe the demographic profile, prevalence, pattern, and risk factors for retinal vein occlusion (RVO) in patients over 40 years of age presenting to the Liberia Eye Centre, John F Kennedy Memorial Medical Centre, Monrovia, Liberia.
A retrospective study was conducted on patients presenting to Liberia Eye Centre from July 2017 to February 2021. A total of 17506 new patients were examined during this period out of which 10813 patients were over 40 years of age. Data were collected from the electronic medical record system database. The variables in the collected data included age, gender, location, laterality of eye affected, uncorrected visual acuity, best-corrected visual acuity, intraocular pressure, ocular diagnosis, systemic risk factors, and associated complications.
Of the 10813 patients, RVO was found in 111 patients with an overall prevalence rate of 1.03% (95% confidence interval 0.80-1.2). Central RVO (CRVO) was more common than branch RVO (BRVO) in the defined population with similar proportions of both genders. The mean age for any RVO was 64.45 ± 12.27 standard deviation (SD) years ( = 0.734). Majority of the cases of RVO were from Lofa ( = 20; 18%). Fifty-five (61.1%) patients had hypertension, 5 (5.6%) had diabetes mellitus, and 6 (6.7%) had dyslipidemia. More than one systemic risk factor was present in 24 (26.7%) patients. However, none of the systemic risk factors were statistically significant. Visual acuity was most affected in patients with CRVO, with a visual acuity of <3/60 in 45 (63.4%) patients compared to 12 (30.0%) in BRVO patients. Glaucoma was present in 34 (30.6%) patients. The most common ocular complication was macular edema ( = 62, 55.8%) followed by vitreous hemorrhage ( = 8, 7.2%).
RVO was detected in 1.03% of the study population over the age of 40 years in Liberia, CRVO being more common than BRVO. The clinical presentation of RVO in the Liberian population for the first time provides insight into the burden of the disease and opportunity for further research.
本研究旨在描述就诊于利比里亚蒙罗维亚约翰·F·肯尼迪纪念医疗中心利比里亚眼科中心的40岁以上患者视网膜静脉阻塞（RVO）的人口统计学特征、患病率、模式及危险因素。
对2017年7月至2021年2月期间就诊于利比里亚眼科中心的患者进行回顾性研究。在此期间共检查了17506名新患者，其中10813名患者年龄超过40岁。数据从电子病历系统数据库收集。收集数据中的变量包括年龄、性别、地点、患眼侧别、未矫正视力、最佳矫正视力、眼压、眼部诊断、全身危险因素及相关并发症。
在10813名患者中，发现111名患者患有RVO，总体患病率为1.03%（95%置信区间0.80 - 1.2）。在该特定人群中，中心性视网膜静脉阻塞（CRVO）比分支性视网膜静脉阻塞（BRVO）更常见，且男女比例相似。任何类型RVO的平均年龄为64.45±12.27标准差（SD）岁（P = 0.734）。大多数RVO病例来自洛法县（n = 20；18%）。55名（61.1%）患者患有高血压，5名（5.6%）患有糖尿病，6名（6.7%）患有血脂异常。24名（26.7%）患者存在不止一种全身危险因素。然而，没有一种全身危险因素具有统计学意义。CRVO患者的视力受影响最大，45名（63.4%）患者视力<3/60，而BRVO患者中这一比例为12名（30.0%）。34名（30.6%）患者患有青光眼。最常见的眼部并发症是黄斑水肿（n = 62，55.8%），其次是玻璃体出血（n = 8，7.2%）。
在利比里亚40岁以上的研究人群中，RVO的检出率为1.03%，CRVO比BRVO更常见。利比里亚人群中RVO的临床表现首次为了解该疾病的负担及进一步研究提供了依据。
