Disorders of the Lashes
- Trichiasis: The misdirection of lashes.
- Distichiasis: The presence of a second row of lashes.
- Madarosis: A decrease in number, or a complete loss of lashes.
- Hypertrichosis: Excess number of lashes.
Treatments differ in each case and include:
- Epilation (removal of lashes with forceps – temporary, as they grow back in 4-6 weeks).
- Electrolysis (an electrocautery needle inserted into the hair shaft and a current is applied – multiple treatments are required).
- Cryotherapy (the application of very low temperatures to disable the follicle).
- This condition is dealt with in detail elsewhere on this website.
- Blepharitis refers to inflammation of the eyelids, particularly at the lid margins. It is a common disorder and may be associated with a low-grade bacterial infection or a generalized skin condition.
