Diabetes mellitus is a metabolic disease in which glucose homeostasis is defective. This causes sustained elevated blood glucose level, which affects some vital organs like the brain and skeletal muscles. Diabetes affects major systems in the body most importantly the visual system and has been implicated in angiopathy, nephropathy, myopathy and retinopathy. The aim of the present study is to investigate the relationship between visual acuity, Intra ocular pressure, anthropometric parameters and blood glucose amongst diabetics attending a diabetic care center in Port Harcourt. The Intra Ocular Pressure, Body Mass Index and Fasting blood sugar were determined. Uncontrolled blood sugar for males were 30(53.6%), females, 23(52.3%). The relationship between fasting blood glucose and gender was not statistically significant (P<0.00). Most subjects were in over weight category (46%), normal (26%), obese (28%) and underweight (1%). 87% of the subjects had normal intra ocular pressure, 9% elevated intra ocular pressure and 4% had pathological condition. The outcome of this study indicated that most subjects, due to their regular monthly tests and check-up activities, had controlled blood glucose levels and regulated blood pressure which led to reduced ocular challenges such as lens opacity, cataract, glaucoma and diabetic retinopathies among them. More diabetic care centers should be established in every state to educate, manage and care for most diabetic patients in Nigeria to avoid complications arising from uncontrolled blood glucose leading to blindness and other systemic conditions.
