WHAT IS CONCRETIONS ?
Concretions are formed due to accumulation of inspissated mucus and dead epithelial cell debris into the conjunctival depressions called loops of Henle.
They are commonly seen in elderly people as a degenerative condition and also in patients with scarring stage of trachoma.
The name concretion is a misnomer, as they are not calcareous deposits.
Clinical features of concretion
Concretions are seen on palpebral conjunctiva, more commonly on upper than the lower.
They may also be seen in lower fornix. These are yellowish white, hard looking, raised areas, varying in size from pin point to pin head.
Being hard, they may produce foreign body sensations and lacrimation by rubbing the corneal surface.
Occasionally they may even cause corneal abrasions.
Treatment of concretion
It consists of their removal with the help of a hypodermic needle under topical anaesthesia.
