ObjectiveOne of the diabetes mellitus (DM) complications is foot ulcers. Foot ulcers are influenced by many factors. DM puts patients at risk of injury because of visual impairment. Hyperglycemia can damage blood vessels, which results in peripheral artery disease (PAD). The purpose of this study was to find the relationship of visual impairment and PAD with diabetic foot ulcers.MethodsThis research used observational analytic study with case–control methods. It used purposive sampling in 34 DM patients with foot ulcers and 34 DM patients without foot ulcers. The research instruments were an interview guide to assess visual impairment, physical examination to assess PAD, and documentation study, which was used to know the incidence of diabetic ulcers.ResultsThe results showed that the respondents who experienced ulcers with visual impairment were 44.1% and the respondents who had foot ulcers with PAD were 73.5%. The results of statistical tests showed that there was no relationship between visual impairment and the incidence of ulcers (P = 0.166). The respondents with PAD will have a chance to suffer from foot ulcers 5.808 times higher than those who do not have PAD.ConclusionsThere is no relationship between visual impairment and the incidence of diabetic foot ulcers in Dr. Moewardi Hospital, but there is relationship between PAD and the incidence of diabetic foot ulcers in Dr. Moewardi Hospital. Suggestions of this study are to do foot screening and educate about the importance of foot care to prevent the occurrence of diabetic ulcers.

This leads to inflammation in the vascular endothelium, which results in increased progression of atheroma plaque formation, resulting in progressive narrowing of the vascular lumen. An increased risk of peripheral artery disease (PAD) is determined by the duration of DM. Prevalence of PAD is four times more common in diabetic patients. The absence of pulse in the periphery may predict poor prognosis of the foot to be amputated with or without foot ulcers. The presence of a history of leg pain and no pulse on both legs increases the likelihood of vascular insufficiency.<a ref-type="bibr" href="#j_FON-2019-0023_ref_009_w2aab3b7b9b1b6b1ab1b6b9Aa">9</a>,<a ref-type="bibr" href="#j_FON-2019-0023_ref_010_w2aab3b7b9b1b6b1ab1b6c10Aa">10</a></p><p>In addition to PAD, other factors affecting foot ulcers are vision impairment.

Most of respondents were diagnosed with DM in older age, when it was easy to experience vision problems such as presbyopia and cataracts. Although respondents experience visual impairment, providing family support to help check legs, prevent injuries, create a safe environment, and use sticks to assist in the activity may prevent them from the incidence of ulcers.<a ref-type="bibr" href="#j_FON-2019-0023_ref_014_w2aab3b7b9b1b6b1ab1b6c14Aa">14</a></p><p>PAD was significantly related to the incidence of ulcers by multivariate analysis.
