Abstract
Objectives: To find out the prevalence and severity of keratoconus in spring catarrh patients. Study Design: Descriptive and Perspective study. Setting: OPD K.D.A Teaching Hospital Kohat. Period: March 2017 to October 2019. Material & Methods: All patients suffering from spring catarrh were included in the study after consent. Proper proforma was designed for record. Detail history was taken and for diagnosis all the patients were properly examined with slit lamp. Visual acuity was checked. Radioscopy for irregular scissor reflex and fundoscopy for oil droplet sign for keratoconus was carried out. Keratometry was done to determine the astigmatism and severity of keratoconus Grading of keratoconus was done by the highest axis of corneal power on keratometry as mild (< 48 D), moderate (48-54 D) and severe (> 54 D). Suspected cases were advised corneal topography. Total 480 patients were included in the study. Out of these 480 patients 295 (61.45%) were male and 185 (38.54%) female. The age range of patients was 9 to 37 years. Results: Out of 480 patients, 47(9.79%) patients had keratoconus in which 36(76.59%) were male and 11(23.40%) were female. Out of 47 patients 19 (40.42%) had mild, 22(46.80%) had moderate and 6(12.76%) patients had severe keratoconus. Conclusion: Keratoconus has strong association with spring catarrh.
