Abstract

OBJECTIVE

The magnitude, determinants of visual impairment, bilateral blindness and low vision among diabetics in Oman were estimated as part of Oman Diabetic Eye Study 2002. This study presents the outcomes and additional risk of visual impairment in diabetics.

METHODS

A cross-sectional study of 2,520 randomly selected diabetics was conducted in 2002 in 10 regions of Oman. The sample was represented by 5,564 diabetics referred for eye checks. Ophthalmologists noted the vision and ocular manifestations of diabetes. Physicians reported the systemic manifestations of diabetes. The magnitude of visual disabilities, bilateral blindness, legal blindness and low vision were estimated and compared to the rates in the population.

RESULTS

The prevalence of visual impairment in diabetics was 28.4% (95% confidence interval [CI] 27.20-29.57). It was 34.6% (95% CI 32.93 to 36.32) in females and 21.2% (95% CI 19.59 to 36.32) in males. The prevalence increased in age. The prevalence of bilateral blindness (vision <0.05) was 0.7%, legal blindness 9.8% (vision <0.1) and low vision 27.7% (vision <0.5).

CONCLUSION

The risk of visual impairment is 25 times more in diabetics than in the Omani population. Therefore, to prevent further increase of visual disabilities, the national health program should prioritize the eye care in diabetics and the predictors of visual disabilities should be further investigated.

摘要

目的

作为2002年阿曼糖尿病眼病研究的一部分，对阿曼糖尿病患者的视力损害、双眼失明和视力低下的程度及决定因素进行了评估。本研究呈现了糖尿病患者视力损害的结果及额外风险。

方法

2002年在阿曼的10个地区对2520名随机选取的糖尿病患者进行了横断面研究。样本由5564名被转诊进行眼部检查的糖尿病患者组成。眼科医生记录了糖尿病患者的视力和眼部表现。内科医生报告了糖尿病的全身表现。对视力残疾、双眼失明、法定失明和视力低下的程度进行了评估，并与总体人群的发生率进行了比较。

结果

糖尿病患者视力损害的患病率为28.4%（95%置信区间[CI]27.20 - 29.57）。女性患病率为34.6%（95%CI 32.93至36.32），男性患病率为21.2%（95%CI 19.59至36.32）。患病率随年龄增长而增加。双眼失明（视力<0.05）的患病率为0.7%，法定失明为9.8%（视力<0.1），视力低下为27.7%（视力<0.5）。
