Covariates on Vision Problems and their Relatonship of Rajshahi Medical College Hospital (RMCH) Abstract Vision is very important for all living being and the sharpness of vision may be afected due to various causes like scarcity of the proper vitamins, minerals, balanced food, age and some other related covariates. The objectves of the research was to identfy the infuencing covariates among the 21 assigned variables of 72 patents who were sufering from various eye related problems following authors’ survey data using the purposive sampling technique. A throughout investgaton and constructve analysis of the infuental covariates have performed and the results are enlisted in result discussion secton accordingly. As additon, history of vision problem and family history of diabetcs, pathological examinaton, duraton of diabetcs and regularity in visitng doctors may have causal efect on vision problems we have given priorites on them. According to the pathological examinaton records only 4% patents depend on the HbA1c test, 22% on urine test and 74% on RBS test to know the diabetc status of the study area. Hypertension is one more risk factor having negatve infuences on the vision problem. This study shows about 39% of the patents have hypertension and rest 61% of the patents do not have hypertension. About 54% of the patents feeling that they are facing vision problem due to aged cause and rest 45% of the patents are feeling that they are facing vision problem due to diabetcs. It is evident from the ophthalmic examinaton results that about 18% of the patents have normal vision and somewhat any deviaton from normal vision have found for the rest 82% patents. The associaton between diferent covariates have been analysed following the Pearson’s Chi-Square test statstc. The asymptotc signifcant relaton of vision has been unearthed with controlling method of diabetcs and duraton of hypertension will help to the concerning agencies for policy implicaton in the consigned area.

The clarity or sharpness of vision is named as the visual acuity and it is the amiability of the eye to see and distnguish fne details. The visual problems have been seen in all aged peoples especially in the peoples of poor countries due to the defciency of proper food and nutriton. Because the people of these countries have to face some sort of scarcity of the proper vitamins and minerals even balanced food. As a result they may sufer from such kind of vision problems. Impairment in acuity is related with difcultes in physical functon of the patents [1- 3]. An estmate by the WHO suggested that 161 million person’s world-wide have visual impairment including 37 million blind and 124 million with visual impairment less severe than blindness. But total number of persons with visual impairment of the world including uncorrected refractve error was estmated as 259 million 61% higher than commonly quoted WHO estmate. The number of persons in the world with visual impairment due to uncorrected refractve error could range from 82-117 million [4]. Based on WHO blindness in Singapore is 0.5%, Malaysia is 0.3%, Taiwan is 0.6%, Bangladesh is 1.5%, Indonesia is 2.2% and India is 4.3%. Besides these the emotonal distress and low socializaton [5,6] are considered as the part of quality of life. As such vision may depend on so many factors, we consider that factors as covariates. A good numbers of studies have been found in the
