Abstract

Purpose: To determine the distribution of corneal topographic patterns measured by Pentacam in a rural population based on age and gender. Methods: In this cross sectional population based study, two different rural regions in Iran were randomly selected, by random cluster sampling. Detailed optometric examination including – refraction (objective and subjective), visual acuity assessment and slit lamp evaluation and Pentacam topography were conducted for all participants. Results: Corneal topographic maps of 794 rural cases were evaluated. The mean age of patients was 32.1+18.53 years. A total of 398 patients (51.1) were male and 396 patients (49.9) were female. The most prevalent topographic pattern was Symmetric Bowtie (21.6) and after that Superior Steepening (17.9) and the more rare patterns were Asymmetric Bowtie with Skewed Radial Axis (AB-SRAX) (3) and Round (5.6). The most prevalent topographic patterns in age range from 5-20yr were Oval and Symmetric bowtie (25.9), in 21-40yr was Symmetric bowtie (27.8) and -in >40yr was the Irregular pattern (18.6). Conclusions: This study showed us an important information about corneal topographic patterns of Iranian rural population for the first time. Our result showed that Symmetric bowtie was the most prevalent and skewed radial axis was the rarest topographic pattern. Using this finding can help us in diagnosing and treating the corneal disorders.
