The cornea, conjunctiva and the limbus comprise the tissues at the ocular surface. All of them are covered by stratified, squamous, non-keratinising epithelium and a stable tear film. The ocular surface health is ensured by intimate relationship between ocular surface epithelia and the preocular tear film. It is essential to establish accurate diagnosis for appropriate management of complex ocular surface disorders. Management has improved with introduction of the limbal stem cell concept and amniotic membrane transplantation.
