It can be single or multiple.Infection of chalazion called internal hordeolum. Treatment of it including hot compressor with digital massages of the eyelids. Surgeries with chalazion excision can be done if those measures failed. Internal hordeolum can be treated in the same way as styes and after the infection is cured, surgical excision should be done for chalazion or the remaining mass. 5- Conjunctivitis: Inflammation of conjunctiva which can cause red painful eyes. 6- Dry eyes: Blepharitis especially posterior form can lead to deficiency for tear films or tear film instability due to imbalance between aqueous and lipid components of the tear film. Dry eye will increase the risk of micro erosions of the cornea which with time can lead to corneal infections. 7- Keratitis: Injury to the cornea. Constant irritation of the cornea from inflamed eyelids or misdirected eyelashes may cause lesions and erosions on the cornea which with time can cause corneal ulcer and infections.
