Blepharophalangeal cysts in children are a common ophthalmologic condition associated with blocked secretion of the blepharophalangeal glands. Children may present with painless hard nodules under the skin of the eyelids, congestion of the eyelids, and other uncomfortable symptoms. Blepharophalangeal cysts are chronic inflammatory granulomas of the blepharophalangeal glands that form as a result of obstruction of the blepharophalangeal drainage ducts and retention of secretions. Children may present with painless hard nodules under the eyelid skin, which are usually painless. Smaller cysts require careful palpation to detect, and there may be limited congestion on the conjunctival surface of the lid corresponding to the mass. If the size of the cyst is small, the child may be able to apply localized warm compresses to the eyelid to promote the regression of the swelling. If the size of the mass is large, the child may be treated with surgery, such as surgical removal of the mass. It is recommended that children with blepharocysts be seen promptly for evaluation of their condition and treatment as prescribed by their physician.
