Abstract
The present study was conducted to determine corneal topographic characteristics of children with vernal keratoconjunctivitis (VKC) and compare the corneal topographic indices in VKC subjects with normal subjects MATERIAL AND METHOD: In the hospital based comparative study, 115 consecutive subjects with VKC and 102 age and sex matched normal subjects were selected for the videokeratography with NIDEK ophthalmic operating system. Keratoconus-like topography was determined based on the expert classifier system. Other assessments included visual acuity testing with LogMAR chart, slit lamp biomicroscopy, dilated fundus examination, measurement of central corneal thickness and intraocular pressure. Topographic indices were analyzed and compared using unpaired t-test among different groups. Sensitivity and specificity was estimated by the ROC curve.
