The data of disease history, visual acuity, eye disease and introcular pressure were collected by inquiry and examination. Photography of ocular fundus was used to confirm the diagnosis of DR. Results A total of 535 residents excepted the examination with the participating rate of 90.68%, in whom 146 (27.29%) were identified as with DR. The incidence of single and proliferative DR was 22.29% and 4.30%, respectively. Duration of DM was the independent risk factor of DR, while long duration of DM, accompanied with peripheral neuropathy and body mass index was the in-order independent factor of proliferative DR.

  • The prevalence of age-related macular degeneration in the rural area of Qidong County, Jangsu Province

    ObjectiveTo study the prevalence of age-related macular degeneration (AMD) in the population aged 50 and over in Qidong County of Jangsu Province. Methods3644 individuals from 4 villages were randomly selected by clustering sampling method, according to the household registration information and door to door visits. Visual acuity was measured by modified Bailey-Lovie E logMAR chart. The examination of eyelids, cornea, lens and fundus were also carried out. The diagnosis of AMD was made according to the clinical hierarchy system by Age-Related Eye Diseases Study. χ2 test was used to analyze the prevalence of AMD and its related factors. ResultsAmong 3644 selected individuals, 2985 individuals received examination with a participating rate of 81.92%. In total 97 patients (136 eyes) had AMD with a prevalence rate of 3.25%. Among them, 71 patients (105 eyes) had early stage of AMD (2.38%); 26 patients (31 eyes) had late stage of AMD (0.87%). In these late stage patients, there were 9 patients (13 eyes) of exudative lesions (0.30%). There were 32 male (3.11%) and 65 female (3.32%) patients. There was no statistically significant difference between male and female prevalence (χ2=0.29, P > 0.05). Correlation analysis results showed that the long-term smoking (χ2=15.19) and heart cerebrovascular disease (χ2=81.50) was associated with AMD (P < 0.05). ConclusionsThe prevalence rate of AMD is 3.25% in the residents aged 50 and above in the rural area of Qidong County, Jangsu Province. Long-term smoking, high blood pressure and cardiovascular disease are the risk factors of AMD.
