CORNEAL TOPOGRAPHY IN VERNAL KERATOCONJUNCTIVITIS (VKC)
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2018, Vol 7, Issue 19
Abstract
BACKGROUND Vernal keratoconjunctivitis (VKC) is a seasonally recurring bilateral inflammation of cornea and conjunctiva found in individuals with atopic background characterised by symptoms like itching, watering, foreign body sensation. Chronic epithelial trauma provoked by eye rubbing due to intense ocular itching has been postulated as important risk factor in the pathogenesis of keratoconus. Our aim was to detect anterior corneal surface changes like astigmatism and keratoconus by topographic evaluation of cornea. MATERIALS AND METHODS This is a descriptive study carried out on 100 patients of VKC of age below 15 years at Sarojini Devi Eye Hospital between August 2016 and July 2017. Best corrected visual acuity (BCVA), slit lamp biomicroscopy and corneal topography were done in each patient. Parameters like steep K, flat K and astigmatism were analysed. Keratoconus like topography were noted. RESULTS Out of 100 patients, 77 were males and 33 were females. Majority were in the age group of 5 - 10 years. Majority of patients presented with mixed type, i.e. 62%. Out of 100 patients, astigmatism < 1D which is physiological was seen in 50% (Males- 37, Females- 13) of patients, astigmatism 1-2 D was seen in 29% (Males- 22, Females- 7) of patients, astigmatism > 2D was seen in 14% (Males- 11, Females- 4) of patients and Steep K > 47.2 D + astigmatism > 1.5 D i.e. keratoconus like topography was seen in 7% (Males- 7) of patients. CONCLUSION Incidence of astigmatism and keratoconus in VKC patients is more when compared to general population of same age group.
