What is Trichiasis:- Trichiasis is a medical term, it is a very common lid abnormality. It is positioned eyelashes that grow back toward the eye, touching the cornea or conjunctiva. Read More:-
Misdirected eye lashes are called trichiasis. Eyelashes 'cilia' emerging normally i.e. from anterior border of lid margin are misdirected backward towards the ocular surface 'cornea'. Tarsal plate remains normal in position. Any condition causing entropies "involution, cicatricle as in Trachoma or spastic entropies" will cause misdirected lashes 'Trichiasis' to rub against cornea.
Causes of Trichiasis:-
1. Secondary to chronic inflammatory conditions like Trachoma, Stevens- Johnson Syndrome, Pemphigus, Blepharitis, traumatic or operative scar, blepharitis "Ulcerative" and chemical burns
2. It may be idiopathic
Treatment:-
1. Epilation of affected eyelash, but they grow in 4- 6 weeks
2. Diathermy: 30 mA current is passed in the root of affected eyelash for 10 seconds then epilated
Electrolysis: done under local anesthesia by injecting lignocaine along the lid margin to anaesthetize root of eyelashes. Positive pole is applied temple. Negative pole is introduced in hair follicle and current of 2 mA is used (bubble is seen at root of eyelash then) eyelash is then epilated
