Abstract

Background:- Diabetes is no longer a disease of affluent and industrialized countries. It affects virtually all ocular structures and can lead to blindness. Routine eye examination is necessary for early detection of ocular involvement and prevention of blindness. Only few diabetics have regular eye examination. Aim:- To study the awareness of ocular complications of diabetes among diabetic patients Methodology:- A cross-sectional prospective study of 148 randomly selected diabetic patients was done. A semi structured questionnaire was administered to these patients by an interviewer who is medical personnel, not below the level of a house-officer. Informed consent was obtained from the patients before filling the questionnaires. The information obtained include the biodata, educational level, duration of diabetes, whether they were aware that diabetes can affect other parts of the body, if yes which parts, which parts of the eye can it affect, how can it affect the eye, whether or not routine eye examination is necessary in diabetics, if yes how often, how did they learn about diabetes and how they think awareness of diabetic complications can be improved. The results were collated and analyzed using SPSS version 13, with chi square done where necessary. Results:- A total of 148 patients were studied. Their ages range between 21years and 82years, with a mean of 58.53 +10.4years. Majority were between 36-60yearrs of age. Eighty-three (56.1%) had educational level within secondary level 40(27 %) tertiary education while 25(16.9 %)) do not have formal education. Most common co morbid factor was hypertension, found in 44.6%. One hundred and twenty three (83.1%) were aware that diabetes could affect other parts of the body, 41% were aware of brain affectation, 54% were aware that it can affect the kidneys, 77.7% were aware that it can affect the eyes, 39.2% blood vessels, 66.2% the legs, 40.5% the skin and 41.9% were aware that it can affect the genitals. Of the 77.7% who were aware that it can affect the eyes, more than half (58.8%) did not know the part of the eye that can be affected. 20.3% knew that it can affect the crystalline lens,4.1% external eye, 13.5% the retina and 3.4% thought it can affect the combination of external eye, lens and the retina. Forty nine respondents (33.1%) did not know that routine eye examination is necessary in diabetics, 16.2% says eye examination should be once, 18.2% twice, 18.9% thrice and 26.4% none. Only 18 (12.2%) respondents got their information of eye complication from eye specialists. Sixty- one respondents (41.2%) do not know how diabetes can affect the eye, 29.7% knew that poor control is the problem, 8.8% think it is due to long duration, 7.4% believe it was a combination of poor control and long duration, 2% claim it is due to infection, 8.8% combination of infection, poor control and long duration and 0.7% erroneously believe thinking too much of DM can result in eye complication. Patients who have been diabetic for more than 10years are more aware that diabetes can affect the eye than those below 5years (92.3% vs. 7.2%, p=0.001). Awareness of diabetic complication is better in those with tertiary education than others (p=0.001). Conclusion:- We conclude that though awareness of ocular complication of diabetes mellitus is high, the level of knowledge is low. Health Practitioners especially eye care specialist need to intensify health education through media, regular health talks in clinics to increase knowledge and increase health seeking behaviours of diabetics in the.
