Abstract:

PURPOSE: To determine the frequency of the patterns of topography in keratoconus in Pakistani population Methods: A retrospective observational study carried out in Al-Shifa Trust Eye Hospital Rawalpindi included 452 eyes of 226 patients with diagnosed bilateral keratoconus without any treatment, from January 2018 to December 2021. There were 114 (25.2%) female and 112 (24.8%) males with mean age 12.6 ± 8.3 years. For all eyes, topographic patterns of the axial power maps, anterior and posterior elevation maps and pachymetry maps were obtained using Galilei G4. RESULTS: Out of 452 eyes there were 40.3% with symmetric patterns and 59.6% with asymmetric patterns. Oval pattern cone was commonly observed pattern (28.8%) and irregular was the least observed 2.2%. SRAX was observed in 5.7 % of eyes. CONCLUSION: The distribution of topographical patterns in keratoconus are almost like Iranian population. Patterns with SRAX were 5.7% which showed that keratoconus prevalence may be high in our population
