Topical antiglaucoma treatment with prostaglandin analogues may precipitate meibomian gland disease.

The popular use of topical prostaglandin analogues (TPAs) in glaucoma patients has a well-documented association with changes in number, length, thickness, and growth pattern of eyelashes. A link between meibomian gland disease and seborrheic blepharitis resulting from topical administration of prostaglandin analogues has not been made to the authors' knowledge. A retrospective study of 43 patients presenting for incision and curettage of chalazion to the operating theatre over a 2-year period was performed.

Thyroid orbitopathy obscuring the diagnosis of a rare neuromuscular hamartoma of the superior rectus muscle in an adult.

A neuromuscular hamartoma is a rare benign tumour that is most frequently associated with peripheral nerves. The authors present a case of a 61 year-old man with bilateral exophthalmos and lid retraction who developed further proptosis and chemosis in the left eye over a five month period. An initial diagnosis of thyroid orbitopathy was made and he had a limited response to two courses of oral steroid administered in another centre.

Enophthalmos associated with primary breast carcinoma.

Background And Objective: The most common source of metastases to the orbit is from breast carcinoma. The orbital presentation can be the presenting sign of the cancer. Proptosis or exophthalmos is the more usual way metastases present, associated with ocular motility problems or diplopia.

Beware the empty curette!

Background And Objective: Chalazions are a common occurrence in the eyelids due to chronic inflammation in the tarsal plate. Treatment of non-resolving cases may involve incision and curettage. Chalazions that are recurrent should arouse suspicion.
