Study of frequency of corneal astigmatism in patients of vernal keratoconjunctivitis

Abstract

Aim: Our aim was early detection of corneal astigmatism in VKC patients by corneal topography and find out its frequency.Material and Method: This is a cross sectional observational study done on 100 patients (200 Eyes), between age group of 5 to 15 years and diagnosed with VKC. Parameters like Flat K, Steep K, and Astigmatism were analysed. Data were compared with age and gender matched control group.Result: Out of 100 patients, 71 were Male and 29 were Female with mean age of presentation 10.36 ± 3.05 years. Average corneal astigmatism in right eye of caseswas1.51 ±0.49 and in control was 0.68± 0.42 (p value,0.05). Average corneal astigmatism in left eye of cases was 1.49 ±0.49 and in control was 0.69 ±0.44 (p value<0.05).Conclusion: Frequency of corneal astigmatism in VKC patients is more when compared to general population of same age group. All the cases of VKC should undergo corneal topography for early detection of astigmatism and thus to prevent Keratoconus.
