ENGLISH SUMMARY : Background: The prevalence of diabetes mellitus and its complications is rising globally and many factors which include sedentary lifestyle, obesity, aging, population growth among others have been attributed to this. Ocular complication adversely affects communities and individuals. Aim: To determine the prevalence and factors associated with ocular complications among patients with type 2 diabetes at Onandjokwe hospital Methods: A cross-sectional survey was conducted. Data on presence of hypertension, HIV infection, and level of FPG for 61 patients with diabetes was extracted from the patients’ records. Weight and waist circumference measurement, and eye examination were carried out. Using systematic random sampling, participants were recruited from the two male and female medical wards, and the two medical general outpatient departments. Results: Of the 61 patients who had eye examinations, 39% had ocular complications with abnormalities in visual acuity, 32 (52%) being the most common. Other abnormalities included visual field defects 30 (49%), lenticular defects 28 (46%), retinal defects 25(41%), conjunctival defects 25 (41%) and raised intra ocular pressure 15 (25%). Patients with age greater than 50 years had a slightly higher prevalence of ocular complications 31 (52.5%) as was the case with high Fasting Plasma Glucose (FPG) and high blood pressure with 38 (65.5%) and 33 (55%) respectively. However, only BMI (p=0.008) was found to have a statistically significant association with development of ocular complications among the participants with high BMI increasing risk of ocular complications 8.5 times (Fisher exact 8.5, p-value 0.008). Conclusion: There was a high prevalence of ocular complications among patients with diabetes in Onandjokwe hospital. BMI was found to be a significant modifiable associated factor among patients with of ocular complications.
