Predictors for attending annual eye screening for diabetic retinopathy amongst patients with diabetes in an urban community of Beijing.

Aim: To gain a better understanding of possible factors that may influence the decision of diabetes persons to participate in annual eye screening in an urban community setting of China.
Methods: A structured interview including questions on attendance of eye screening, knowledge and awareness of diabetic retinopathy was conducted. The presence and degree of retinopathy were assessed using two field non-mydriatic retinal photography.
Results: Totally 720 diabetes persons were recruited and 519 were enrolled in this cross-sectional study. In this urban setting of Beijing, among diabetes patients of average of 10y duration, 77% confirmed having undergone at least one eye examination and 61% reported having at least one eye examination with dilated pupil. As for the last 12mo, the number decreased to 210 (47%) and 131 (30%) separately. Most of the participants (95%) were aware that diabetes could affect their vision and that regular eye examination was necessary. Very few of them (12%) however were aware that the early stages of diabetic retinopathy presented without symptoms of vision loss. Having attended patient education on diabetes was effective in building awareness about diabetic eye disease and was a significant positive predictor for attending eye screening [education in a year, Adj. OR=0.47 (0.29-0.74), P <0.001, education years ago, Adj. OR=0.56 (0.33-0.96), P =0.036]. The duration of disease also increased the likelihood of having undergone eye screening (Adj. OR=0.96, P <0.05).
Conclusion: Being exposed to education about the complications of diabetes increases the probability of attending diabetic eye screening. An appropriate patient knowledge building strategy should be made available to patients from the time of diagnosis.
