目标：评估尼日利亚三级公共眼科医院中眼部保健工作者的眼部健康状况。

方法：基于医院的横断面研究，这项研究中使用自填问卷收集参与研究的工作人员基本的人口统计学信息。每一位受试者都进行了眼部综合检查，包括裸眼或矫正视力、详细的眼前节和眼后节检查，以及使用Goldman眼压计测量眼压。有青光眼视神经病变征象的，或周围前房深度小于角膜厚度25%的受试者接受了房角镜检查。可能患有青光眼的人进行了中央视野分析(24-2， SITA Standard)。视力使用WHO视力受损分类标准镜像分类。

结果：共有275例保健工作人员进行了筛查，其中176(64%)为非临床工作人员。166人(60.4%)受调查者是男性，13.1%有眼部疾病家族史。大部分受访者(86.2%)视力正常(6/18-6/6)。然而1.5%的有严重的视力障碍。女性有严重视力障碍的比例更大(3.7% vs 0%，P=0.018)。然而，我们观察到临床工作人员和非临床工作人员的视力情况无统计学差异(P=0.41)。右眼和左眼的平均杯盘比分别为0.42、0.45，两者之间的差异没有显著性(t=-0.882， P=0.37)。右眼和左眼的眼压平均为14.1、14.0mmHg。右眼眼压和右眼杯盘比之间、左眼眼压和左眼杯盘比之间存在弱相关。老花和屈光不正是受筛查人群中最常见的眼部疾病。有14位受访者(5.1%)患原发性开角型青光眼。而47人疑患有青光眼。

结论：未矫正的屈光不正、白内障和青光眼是眼部保健工作者中最常见的导致视力障碍的眼部疾病。这项研究强调了定期进行工作人员体检以保证及时的诊断和治疗对患病人员的必要性。

METHODS: This is a cross sectional hospital-based study in which a self-administered questionnaire was used to collect basic demographic data from the participating staff. Comprehensive ocular examination including presenting visual acuity with glasses if available, details anterior segment and posterior segment evaluations were performed in each patient as well as intraocular pressure measurement using Goldman Applanation Tonometer. People with evidence of glaucomatous optic neuropathy or peripheral anterior chamber depth less 25% of the corneal thickness had gonioscopy performed on them. People suspected to have glaucoma had Central Visual Field analysis(24-2, SITA Standard).Vision was categorised based on WHO classification of visual impairment.

RESULTS: A total of 275 health workers were screened, out of which 176(64%)were non-clinical staff. Overall 166(60.4%)of the respondents were males and 13.1% had family history of ocular disease. Majority of the respondents(86.2%)have normal vision(presenting visual acuity of 6/18-6/6), however 1.5% have severe visual impairment. There were more females with severe visual impairment(3.7% vs 0%)(P=0.018). However, we observed no significant difference in vision between the clinical and non-clinical staff(P=0.41).The mean cup-disc ration(CDR)in the right and the left eye were 0.42 and o.45 respectively. No significant difference between the RE and LE CDR(t=-0.882, P=0.37). The mean intraocular pressure in the RE and LE were 14.1 and 14.0mmHg. Weak positive correlation was observed between left IOP and left CDR(Pearson coefficient=0.008, P=0.94). Presbyopia and refractive error were the commonest ocular morbidities discovered among the screened staff. Fourteen respondents(5.1%)have primary open angle glaucoma(POAG)and 47 were classified as glaucoma suspects.

CONCLUSION: Uncorrected refractive errors, cataract and glaucoma are the common ocular morbidities responsible for visual impairment among the eye health workers. This study underscores the need for periodic staff screening to enable prompt diagnosis and timely treatment of ocular diseases in the affected staff.
