Abstract Details


The aim of this study is to evaluate the topographic corneal changes in patients with vernal keratoconjunctivitis (VKC) when compared with a healty control group.


prospective research


Fourty-one patients (eighty-one eye) with active VKC and fourty-one healthy subjects (eighty-two eye)were included in this prospective study.Age, sex, age at onset of symptoms, atopic disease,and duration of the VKC symptoms were recorded.All subjects underwent a complete ophthalmic examination, including best-corrected visual acuity and slit- lamp biomicroscopy. Subjects who met the eligibility criteria were examined with Pentacam (Oculus HR inc., Germany) for corneal topography by one trained examiner.


There were no statistically differences between groups in K1, K2,Kmean (p>0,05). The mean Kmaximum value was much higher in VKC group than the control group (p<0,01). There were statistically significant difference between the groups for the mean astigmatism, thickness at the thinnest location, thickness at the apex of the cornea, the difference in the thickness between the apex and the thinnest location, the mean anterior and posterior elevation peak and keratoconus index (p<0.05). The mean corneal volume was higher in VKC group than the control group (p<0,05). According to our parameters, 7 of the 41 subjects (17.07%) were detected as keratoconus and 9 of the 41 subjects (21.95%) were detected as subclinic keratoconus in VKC group.


In our study,in comparison to the control group. increased incidence of topographic characteristics suggestive of keratoconus and subclinic keratoconus were detected in patients with VKC. In patients with VKC, analysis of corneal topography is important for early diagnosis of keratoconus.
