Methods: This was a community based descriptive study carried out in Port Harcourt City LGA, Nigeria using a multistage random sampling technique. Inclusion criteria were Visual Acuity > 6/18, age greater than 18 years and no history of past ocular surgeries or trauma. Socio demographic data was obtained through an interviewer based proforma and included age, sex and tribe. Anthropometric parameters were measured using a standard height and weight automated scale (SECA 769,220). Ocular examinations done included visual acuity, applanation tonometry, and ophthalmoscopy. Axial length (AL) was measured using Amplitude (A) scan ultrasonography (SONOMED PACSCAN 300AP). Data obtained from one eye of the subjects were analyzed using SPSS (Version 17), and P value was set at ≤ .05. Results: The study was made up of two hundred and twelve (212) males (45.5%) and two hundred and fifty four (254) females (54.5%) with M: F ratio of 1:1.2 giving a total of four hundred and sixty six (466) subjects. The age range was 18-92 years and mean age of the subjects studied Original Research Article
