Introduction: Vernal Keratoconjunctivitis (VKC) is the most common and severe form of ocular allergy seen in paediatric patients. If left untreated it can lead to sight threatening complications like corneal ulcer and limbal stem cell deficiency. It is also often associated with dry eyes, which is commonly neglected in children as they cannot express their complaints. We hesitate in performing the dry eye tests like tear film break up time and Schirmer’s test in children owing to their invasive nature. Ocular Surface Analyser (OSA) is a non-invasive tool which is used in adults to assess dry eye status. The purpose of this research is to present the results of evaluation of OSA as a non-invasive alternative for assessment of dry eyes in paediatric VKC. Methods: Prospective pilot study. The clinical parameters recorded were bonini clinical grading, corneal fluorescein staining, Tear-film Break-Up Time (TBUT) and schirmer’s II test. The OSA parameters recorded were non-invasive TBUT (NiBUT), Meibomian Gland (MG) loss, tear meniscus height and lipid layer type. The OSA and clinical parameters were correlated with the modified ocular surface disease index (OSDI) symptom scores.
