Epiphora is the term for excessive tearing. Childhood epiphora is often noted soon after birth, but can be acquired later. When noted during infancy, it is usually due to blockage of the tear drainage system. This type of tearing often improves spontaneously by 6-12 months of age. Medical treatment includes tear sac massage and eyedrops, but if tearing persists, surgical probing of the drainage system may be required. Other rare causes of childhood tearing include pediatric glaucoma and ocular surface disease.
