In this study, we describe the clinicopathologic features seen in six cases of intraocular cilia and review the features of previously reported cases. Ultrastructural studies of the cilia showed partial loss of the cuticle layer, diffuse accumulation of small electron-dense granules in cuticle and cortical cells, and loss of continuous cell membranes of the cortex. The cilia were almost completely intact in most of our cases. Intraocular cilia can be tolerated for long periods.

The clinical findings in 116 patients with a provisional diagnosis of trichiasis are presented. In 69% a small degree of entropion producing lash-globe contact was detected. The term lid border entropion is proposed for this condition, which is recognised clinically by conjunctivalisation of the meibomian gland orifices and anterior placement of the mucocutaneous junction. These features were clearly demonstrated by electron microscopy of a biopsy specimen from one patient. An analysis of other causes of trichiasis is discussed and an attempt is made to clarify the terminology currently in use.

Phthiriasis palpebrarum is an uncommon cause of blepharitis and conjunctivitis and may easily be overlooked. A high index of suspicion and careful examination of the patient's lid margins and eyelashes will lead to the proper diagnosis. Treatment is best accomplished by careful removal of the lice and nits (louse eggs) from the patient's lashes. Local application of a pediculocide such as yellow mercuric oxide N.F. 1% ophthalmic ointment applied twice daily for one week or 0.25% physostigmine (Eserine) ointment applied twice daily for a minimum of ten days, to the lid margins should be considered when the total removal of Phthirus pubis and nits is not possible mechanically. Body hair should be examined for infestation with lice and treated with gamma benzene hexachloride shampoo. This medication should be used with caution in infants, children and pregnant women. Family members, sexual contacts, and close companions should be examined and treated appropriately; clothing, linen and personal items should be disinfected with heat of 50 degrees C for 30 minutes.

In spite of the similarity between hairs and eyelashes the later shows several physiological and anatomical particularities. We performed an ultrastructural study of eyelashes and reviewed their pathology.
